License agreement unity что выбирать. Unity3d и развеивание некоторых мифов

Недавно я прочитал очередную на Хабре, в очередной раз были интересные комментарии - и грамотные, и грамотные не совсем.
Я вдохновился и решил немного прокомментировать происходящее.
Надеюсь, кто-нибудь почерпнет для себя здесь что-то новое и интересное.

Несколько комментариев

«Поддержка кеширования ассетов на клиенте продается за отдельные очень большие деньги (это которая не в браузере, а отдельно на диске)».

В 3.2 есть кеширование для всех (с ограничениями, конечно).

«Автор аккуратно опустил две очень серьёзные проблемы:
- Игры на Unity требуют большого трафика,
- Нельзя использовать сложные динамичные сцены».
«Игры на Unity имеют элементарную игровую механику - сложный бой с несколькими игроками будет весьма тормозить».
«Под сложным боем Я имел в виду совместную игру нескольких игроков. Для Unity это является узким местом. Опускать этот момент нельзя, т.к. основное требование к современным играм - это высокая степень социализации. Игроки хотят играть в игры со своими друзьями. Отметьте, что в социальных сетях игр на Unity практически нет».

Отметьте, что большинство игр в социальных сетях имеет асинхронный принцип работы. Т.е. когда Петя в универе, я пришел и сломал ему грядку – Петя пришел домой, зашел на свою страничку в контакте, разозлился и отправил отряд мстителей ко мне на грядку. А я, естественно, в момент нападения никак не взаимодействую с Петей напрямую. Фраза о том, что «совместная игра нескольких игроков является узким местом Unity» звучит, мягко говоря, неприлично – особенно если говорить о действительно небольшом количестве игроков в одной комнате, либо о стороннем сетевом решении.

«И как результат:
- Игры на Unity у людей с низким трафиком превращаются в кошмар,
- Игры на Unity имеют элементарную игровую механику - сложный бой с несколькими игроками будет весьма тормозить».

Вообще, минимальное приложение в вебплеере будет весить чуть больше 500кб, а дополнительные ресурсы можно подкачивать в Asset Bundles (которые пакуются 7z). Если мы говорим именно о трафике, возникающем при обмене игровыми сообщениями – здесь снова играет роль выбранное решение для сети.

«Unity хорош, но прежде чем бросаться писать осмыслите 2 минуса
1: ЗД не панацея и применять его надо осторожно. Посмотрите на топ аппстора - там в основном 2д игры. Посмотрите на соц игры в которые играют сотни миллионов - там нет 3д. Только небольшое количество игровых механик по настоящему требует 3Д.
2: Сделать сочную притягательную графику на 3Д гораздо сложнее чем на 2Д и удается это только профессионалам. Любители и новички делают с 3Д картинку вызывающую страх и ужас…».

Здесь явно присутствует непонимание того факта, что на Unity можно замечательно делать 2д игры. Чем и занимается целая толпа разработчиков в аппсторе (и некоторый процент игр был\есть в top100, между прочим) и казуальщики.

«В Юнити есть deferred освещение, встроенный редактор шейдеров».

Небольшая ошибочка. По-умолчанию никакого подобного инструмента не поставляется, но есть один качественный бесплатный - Strumpy Shader Editor и один платный редактор шейдеров - ShaderFusion . Шейдинг в 3.х шагнул на встречу разработчику (появились surface shader’ы), поэтому написание собственных шейдеров (без визуального редактора) не представляется чем-то невероятным. Портирование шейдеров проходит, в целом, отлично (к примеру, без проблем можно взять и быстренько переделать под юнити что-то отсюда).

«Он закрыт. Т.е. исходных кодов вам не дадут даже по лицензии».

Исходники можно купить, если вы очень уж серьезный разработчик (правда, стоимость исходников начинается от 100к, я предполагаю, а также я вижу очень призрачную вероятность того, что эти исходники вам понадобятся).

А на лицензии (1500$, если мы говорим про Unity PRO), кстати, несколько раз в год бывают скидки, обычно ~20%. Ограничения базовых версий (Unity за 0$, Unity iPhone за 400$) не так велики – значительное количество проектов можно разработать и на них.

«Кто-нибудь пробовал Unity для Android / iOS? Как впечатления?»

Впечатления отличные.
Недавно, например, проходил конкурс от компании Qualcomm на создание augmented reality приложения (можно было использовать квалкомовский Unity SDK) и призы составляли неплохие 125, 50 и 25 тысяч долларов за первое, второе и третье места соответственно.
Обе платформы разработчики активно допиливают и оптимизируют.
На мощных мобилках поддерживается Open GL ES 2.0 (попиксельное освещение, шейдеры) – это, по-моему, отлично. Можно пытаться делать что-то похожее по качеству на Epic Citadel.

Ещё немного мыслей

«Серьезные сцены удобнее отдать делать artist"ам в 3DS Max"е том же. Единственное что плохо - что из FBX (промежуточный формат между максом и юнити) Unity не импортирует источники света. Пришлось писать плагин к Unity на С++. А это доступно только в платной версии. Вобщем намучались с этим движком.»

Скажите, а зачем было писать плагин на С++, если источники света нормально переносятся в юнити в виде геймобъектов-пустышек (dummy)? Можно договориться с художниками о том, как правильно обзывать источники света и написать небольшой скрипт в юнити, который бы при импорте модельки эти источники бы создавал. И сборка уровня в юнити, и сборка уровня в 3д пакете имеют свои плюсы и минусы – и выбор больше, на мой взгляд, зависит от предпочтений разработчиков.

«Возможно, все-таки стоит взяться за реализацию своего майнкрафта с блекджеком - все возможности вроде есть».

Если это поможет, то существует Unity Minecraft Starter Package .

Сеть

Сетевые решения с API, специально подготовленным для работы с Unity3d:

1. Оригинальный Raknet (c++, не подойдет для вебплеера).
2. NetDog (c++, не подойдет для вебплеера и еще у него какой-то совсем чумовой ценник).

Естественно, можно написать что-то свое на произвольной технологии (c++, Java, Erlang, c#, whatever) и прикрутить какой-то еще существующий networking solution. Что-то основанное на TCP\UDP подходит отлично. Если работать по HTTP протоколу, то наиболее частый выбор это php – хотя, как вы понимаете, тот же Erlang или нечто другое тоже подойдет.

Я собственноручно делал простенький чат (не позиционирую это как достижение, но результат в п.3 меня порадовал), который работал через протокол HTTP:

1. Erlang и вебсервер Misultin для серверной части.
2. Unity3d и его класс WWW для клиентской части.
3. Несколько разнотипных девайсов: iPad и iPhone (Unity iPhone Basic), HTC Desire (Unity Android Trial), PC и Mac (в вебплеере, бесплатная версия Unity) – всё это замечательно работало вместе и обменивалось сообщениями.

Оптимизация

1. Чем меньше draw calls – тем лучше (хотя это не панацея). Раньше с этим боролись специальными скриптами для объединения геометрии в один меш (CombineChildren), собирали хитрые конструкции с костями (например, 1 skinned mesh, 8 костей – 8 независимых друг от друга спрайтов с анимацией, такой подход, например, использовался в топовой iOS игре ZombieVille на юнити). Теперь разработчику помогает static batching, dynamic batching и Umbra (система отсечения невидимых поверхностей \ occlusion culling).
2. Без необходимости лучше не использовать Find\GetComponent и похожие методы - по мере возможности лучше сохранить ссылку на компонент один раз при запуске скрипта.
3. Лучше не выполнять лишних расчетов внутри OnGUI() и не использовать больше одного OnGUI() одновременно.
4. Необходимо следить за таким параметром как Fillrate. Несколько плоскостей размером на весь экран с полупрозрачным материалом способны серьезно убить производительность на PC, не говоря уже о чем-то вроде iPad.

Грабли

1. В юнити не существует «game loop»’a или единой точки входа, как к этому многие привыкли в других движках. Т.е. никто вам не мешает такую штуку организовать, но по-умолчанию работает принцип: каждый game object – это некий набор компонентов (в том числе скриптов), при этом в каждом скрипте может вызываться свой набор событий (Start() , Update() , OnMouseDown() , и т.д.).
2. Первым делом, прежде чем ломиться на форумы, стоит хотя бы попробовать ознакомиться с про обезьянку Лерпца.
3. Чтобы найти game object по имени, используем метод GameObject.Find(“Some Object”); , чтобы получить компонент (в том числе скрипт) на этом объекте (который также часто называют «ГО») – используем код вида ссылка_на_объект.GetComponent<Тип>(); .
4. Более-менее продвинутые разработчики тоже в опасности, но грабли у них более изощренные. К примеру, не все знают, что так широко используемый способ работы с материалами (render.material.color = Color.White; , color.material.SetColor(“_Color”) и т.д.) содержит в себе подлянку: При таком доступе создается копия материала в памяти (instance), и объекты не будут работать с batching’ом (который бывает статический и динамический - а skinned batching, вопреки расхожему мнению, в 3.х не поддерживается). Поэтому тут можно либо работать с renderer.sharedMaterial (но тогда свойства материала изменятся у всех объектов с этим материалом), либо менять цвет вершин используя класс Mesh и шейдер который реагирует на такое изменение цвета.
5. NPOT текстуры это плохо (текстуры со сторонами, не кратными степени двойки). Хорошие размеры это 64, 128, 256 и т.д. На iOS ввиду использования PVRTC компрессии нужно использовать еще и квадратные текстуры. Неквадратные текстуры мылятся в 3д (не относится к GUI), а ещё из таких текстур зачастую замечательно вытекает память. Тут еще можно отметить, что хранить текстуры в юнити проекте в формате jpg абсолютно бесполезно, т.к. среда пережимает графические ассеты в свой формат. Я для локальной разработки больше всего люблю psd, а если работа идет удаленно и нужно гонять туда-сюда через ассет сервер\mercurial\svn много ресурсов – тогда мне начинает больше нравиться png.

• Мега текстурирование , прямо как у Кармака в Rage:
• Отличная в игре (безусловно необходимая вещь), которая теперь входит в стандартную поставку Unity3d вот
• Я где-то слышал мнение о том, что в приложение на Unity3d (для iOS или Android) невозможно интегрировать поддержку iAd, OpenFeint и т.д. Оказывается, врут .
• Проект-пример для работы с kinect’ом.

Минусы

1. Давно юнитек обещает прикрутить нормальный GUI, и всё никак. Но я верю в светлое будущее. С другой стороны всё не так смертельно – если UnityGUI реально вас достал, можно воспользоваться какой-то разработанной в сообществе примочкой, которая рисует всё в 1 draw call и не кушает много процессорного времени (тут, конечно, большой простор для допиливания). Очень хотелось бы увидеть грамотный WYSIWYG для графических интерфейсов в юнити. Если есть время\желание – такой можно, конечно же, оформить самостоятельно, т.к. возможности по модификации Editor IDE в юнити поистине огромны.
2. Можно без особых проблем взламывать композиции, сделанные на Unity. Можно рефлектить код (правда, нетипизированный JS и Boo зачастую могут спасти автора). Можно распаковывать бандли и вебплеерные композиции. Можно загружать сцены и ресурсы в практически исходном виде обратно в редактор. Код, конечно, можно защищать с помощью обфускации, а вот с ресурсами всё сложнее (особенно в вебплеере). С другой стороны, это можно не считать проблемой – весьма субъективный пункт.
3. На данный момент нету поддержки отображения html внутри вебплеера (что, возможно, изменится, т.к. в редакторе тройки был замечен WebKit, который используется в работе Asset Store). Если нужно рендерить html и можно использовать standalone приложение на юнити, то можно посмотреть

Fees for certain Services are set forth on the Site or via the service panel in the Software (the “Service Panel ”). Unity may increase, modify or add new fees and charges for any of the Services from time to time by posting such changes to the Site or within the Services Panel. Unity will provide you with at least 30 days’ notice of any changes affecting existing Software and/or Developer Services you have already started using, and your continued use of such Software and/or Developer Service after the effective date of any such change means that you accept and agree to such changes, as applicable.

You agree to pay all amounts due for the Services as set forth in the online cart, quote or invoice and in accordance with Unity"s payment terms and, if applicable, those of any payment processor. If any payment is not made on time, Unity may deactivate your access to the Services.

Payments made under the Agreement shall be made without deduction or set-off for any withholding taxes, levies, imports, duties, charges and/or fees imposed by any governmental taxing authority except as required by law. If you are compelled to make any such deduction, you will pay to Unity such additional amounts as are necessary to ensure Unity"s receipt of the full amount that Unity would have received but for the deduction. You will be responsible for, and agree to promptly pay, all taxes or duties of any kind (including but not limited to sales, use and withholding taxes) associated with any purchase or your receipt or use of the Services, except for taxes based on Unity’s net income. In the event that Unity is required to collect any tax for which you are responsible, you will pay such tax directly to Unity or its payment processor. Unity reserves the right to collect any applicable sales, use or value added tax.

All sales are final and there shall be no refunds except as required by law. Further, Unity will not allow changes to your purchase after you complete it. Unity may disable all copies of the Software and/or your access to any Services you have licensed or subscribed to in the event you fail to make all payments when due.

You acknowledge and agree that, in the case of certain Services, any estimates of fees and charges provided to you by Unity (whether based on assumed data consumption or otherwise) are solely estimates based on assumptions and that you are fully responsible for the actual fees and charges that accrue.

5.2 Billing

If you purchase Services, you will be asked to provide customary billing information, such as name, company name, billing address, credit card information, and VAT or GST number, either to Unity or its third party payment processor. VAT and GST numbers cannot be added or changed after the purchase is completed. When you provide billing information to Unity or its third party payment processor, you: (i) represent and warrant that you are the authorized user of the card, PIN, key or account associated with such billing information; (ii) agree to pay Unity for all purchases (including all applicable taxes) made via the Site or Services Panel; and (iii) thereby authorize Unity or its third party payment processor to charge your credit card or otherwise process your payment for any purchase, subscription or other fees incurred by you. If you are directed to Unity’s third party payment processor, you may be subject to terms and conditions governing use of that third party’s service and that third party’s privacy policy. Please review such third party’s terms and conditions and privacy policy before using such services.

5.3 Subscription Terms

Any subscriptions you purchase will remain in effect for the initial subscription period, and thereafter will automatically renew on a month-to-month basis at the then-current list price, unless you renew the subscription for a new subscription term or terminate and cancel it as described on the Site.

6. Compliance

To ensure compliance with the Agreement, you agree that within ten (10) days from the date of Unity or its authorized representative’s request, you shall provide all pertinent records and information requested in order to verify that your installation and use of any and all Services is in compliance with the Agreement along with a signed verification that all such information is complete and correct. Furthermore, if you are a Legal Entity, Unity or its authorized representatives may upon reasonable prior notice access and inspect your facilities and computer systems to review and verify your compliance with the Agreement. Any such inspection shall be conducted during regular business hours at your facilities or electronically via remote access. In the event you have impermissibly used Unity Personal (or other products) or have not paid the applicable fees for all Services you have deployed or used, you agree to immediately pay for such Services, as well as the reasonable inspection costs, upon Unity’s demand.

7. Termination And Account Cancellation

Unity will have the right in its sole discretion, and without prior notice to you, to suspend or disable your Unity Account or terminate the Agreement and/or your right or ability to access or use any of the Services if: (a) you breach this Agreement; (b) your use of the Services poses a security risk to, or otherwise adversely impacts, the Services or any third party; (c) your use of the Services subjects Unity, our affiliates or any third party to liability; (d) your use of the Services may be fraudulent; (e) you have ceased to operate in the ordinary course, made an assignment for the benefit of creditors or similar disposition of your assets, or become the subject of any bankruptcy, reorganization, liquidation, dissolution or similar proceeding.

In the event of any suspension, disablement or termination, you acknowledge that: (i) Unity will have no further obligation to provide the Services to you; (ii) all rights granted to you under the Agreement will immediately cease; (iii) you may no longer access any of Your Content that was previously submitted via any of the Services or that was related to your Unity Account, and Unity will have no obligation to maintain or forward you Your Content; and (iv) you will remain liable for all fees and charges for all Services ordered. If Unity suspends, disables or terminates due to your breach, you will also remain liable for any remaining amounts owing for the entire term of your subscriptions. Any suspension, disablement or termination will not affect your obligations to Unity (including, without limitation, proprietary rights and ownership, indemnification and limitation of liability), which by their sense and context are intended to survive such suspension, disablement or termination.

10. Limitation Of Liability

UNITY AND ITS LICENSORS’ TOTAL AGGREGATE LIABILITY TO YOU FROM ALL CAUSES OF ACTION AND UNDER ALL THEORIES OF LIABILITY RELATED TO THE SERVICES WILL BE LIMITED TO THE GREATER OF: (A) THE AMOUNTS PAID BY YOU IN THE MOST RECENT THREE (3) MONTHS FOR USE OF THE SERVICES; OR (B) ONE HUNDRED U.S. DOLLARS (US$100). IN NO EVENT WILL UNITY, ITS LICENSORS OR ANY OTHER PARTY INVOLVED IN CREATING, PRODUCING OR DELIVERING THE SERVICES BE LIABLE TO YOU FOR ANY SPECIAL, INCIDENTAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF DATA, BUSINESS, PROFITS, GOODWILL, SERVICE INTERRUPTION, COMPUTER DAMAGE, SYSTEM FAILURE OR ABILITY TO EXECUTE) OR FOR THE COST OF PROCURING SUBSTITUTE PRODUCTS OR SERVICES ARISING OUT OF OR IN CONNECTION WITH THE AGREEMENT OR THE EXECUTION OR PERFORMANCE OF THE SERVICES, OR FROM THE USE OR INABILITY TO USE THE SITE, COMMUNITIES OR WEBSITE CONTENT, OR FROM ANY COMMUNICATIONS, INTERACTIONS OR MEETINGS WITH OTHERS AS A RESULT OF YOUR USE OF THE SITE, SERVICES OR COMMUNITIES, WHETHER SUCH LIABILITY ARISES FROM ANY CLAIM BASED UPON CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY OR OTHERWISE, AND WHETHER OR NOT UNITY OR ITS LICENSORS HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSS OR DAMAGE. THE FOREGOING LIMITATIONS WILL SURVIVE AND APPLY EVEN IF ANY LIMITED REMEDY SPECIFIED IN THE AGREEMENT IS FOUND TO HAVE FAILED OF ITS ESSENTIAL PURPOSE. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OR EXCLUSION OF LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATION OR EXCLUSION MAY NOT APPLY TO YOU.

11. Controlling Law and Jurisdiction

11.1 Choice Of Law

The Agreement is governed by and construed in accordance with the laws of Denmark, without regard to or application of conflict of laws rules or principles. The United Nations Convention on Contracts for the International Sale of Goods will not apply.

11.2 Arbitration

Except as set forth below in Section 11.3, any dispute arising out of or in connection with the Agreement, including any disputes regarding the existence, validity or termination thereof, shall be settled by arbitration. The parties agree to arbitrate all disputes by simplified arbitration arranged by The Danish Institute of Arbitration in accordance with the rules of simplified arbitration procedure adopted by The Danish Institute of Arbitration and in force at the time when such proceedings are commenced. The parties further agree that any arbitration shall be conducted in their individual capacities only and not as a class action or other representative action, and the parties expressly waive their right to file a class action or seek relief on a class basis. You and unity agree that each may bring claims against the other only in your or its individual capacity, and not as a plaintiff or class member in any purported class or representative proceeding. If any court or arbitrator determines that the class action waiver set forth in this paragraph is void or unenforceable for any reason or that an arbitration can proceed on a class basis, then the arbitration provision set forth above shall be deemed null and void in its entirety and the parties shall be deemed to have not agreed to arbitrate disputes.

11.3 Arbitration Exceptions

Notwithstanding the parties’ agreement to resolve all disputes through arbitration, either party may bring an action in court: (a) to enforce its intellectual property rights (“intellectual property rights ” means patents, copyrights, moral rights, trademarks, and trade secrets, but not privacy or publicity rights), including without limitation to seek injunctive relief; (b) in cases that do not involve intellectual property rights, to seek temporary, preliminary or other expedited or provisional injunctive relief (but not money damages); or (c) collect fees due pursuant to the Agreement. If you reside (or your principal place of business is) within the United States and the parties have an intellectual property rights dispute, you and Unity agree to submit to the personal and exclusive jurisdiction of and venue in the state and federal courts located in San Francisco County, California. If you reside (or your principal place of business is) outside of the United States and the parties have an intellectual property rights dispute, you and Unity agree to submit to the personal and exclusive jurisdiction of and venue in the courts located in Copenhagen, Denmark. The parties agree to accept service of process by mail, and hereby waive any and all jurisdictional and venue defenses otherwise available.

12. General

The Agreement is the complete and exclusive understanding and agreement between the parties regarding its subject matter, and supersedes all proposals, understandings or communications between the parties, oral or written, regarding its subject matter, unless you and Unity have executed a separate agreement governing your use of the Services, in which case such separate agreement(s) will control in relation to the relevant Services. The English language version of the Agreement is legally binding in case of any inconsistencies between the English version and any translations. Any terms or conditions contained in your purchase order or other ordering document that are inconsistent with or in addition to the terms and conditions of the Agreement are hereby rejected by Unity and will be deemed null. You may not assign or transfer the Agreement or any rights granted hereunder, by operation of law or otherwise, without Unity’s prior written consent. Any attempt by you to do so, without such consent, will be void. Unity may assign or transfer the Agreement, at its sole discretion, without restriction. Unity may assign your User account for collection, and the collection agency may pursue claims limited to the collection of past due and owing amount and any interest or cost of collection permitted by law or the Agreement in any court of competent jurisdiction. Subject to the foregoing, the Agreement will bind and inure to the benefit of the parties, their successors and permitted assigns. Except as expressly set forth in the Agreement, the exercise by either party of any of its remedies under the Agreement will be without prejudice to its other remedies under the Agreement or otherwise. Unity will deliver all notices, approvals or other communications required or permitted under the Agreement, including those regarding modifications to the Agreement: (a) via e-mail (in each case to the address that you provide); or (ii) by posting to the Site, the Service Panel or your Unity Account. For notices made by e-mail, the date of receipt will be deemed the date on which such notice is transmitted. The failure by either party to enforce any provision of the Agreement will not constitute a waiver of future enforcement of that or any other provision. Any waiver, modification or amendment of any provision of the Agreement will be effective only if in writing and signed by authorized representatives of both parties.
