Please support C++.
It is because of C ++ that developers used cocos2d-x and created amazing games Not JS and any low quality games. You lead to this… don’t you see…? This engine is already dead for C++ devs who created top charts games(EU and US people) and new unique games. You know that all clones, copycats and rip-off games comes from China so you start to support that even more by choosing JS way for the engine? Nice shoot in the leg. Thats really sad for me. I fell sorry for you @walzer
Hi @cc_x, I’m not sure why you’re so upset. Cocos team has not abandoned C++. Cocos2d-x v3.17 (C++) was released recently. Last I heard, they were also working on Cocos Creator C++ support (not sure about it’s current status though).
Btw, people who want to copy will copy, regardless of the language, be it C++ or JS.
I too was reluctant initially with JS, but instead of being stubborn I tried it out and now find it as good as C++ development. Infact, I love how hassle free it is to play with strings and all other basic pre-built libraries in JS.
The Cocos team is doing a great job and I know they’re often working hard to get new releases out on time. From my side, I’d like to thank them for being proactive and supportive as well.
@slackmoehrle Any update for the upgrade guide? 3 weeks ago, we tested a 1.9.x prototype project in 2.0.1 and it failed to run. A lot of scripts were broken (because a lot of functions were depreciated (math, random etc.)).
6 weeks have been passed since the release of 2.0 and we still do not have a proper upgrade guide and documentations.
I love Cocos and JavaScript (did launch a successful game with Cocos Studio before). But, my team is already looking into another framework (Unity) for future projects. I really wish Cocos provided better support. May be Cocos should start a paid service to fund the project. I think, people don’t mind paying for reliability and quick support rather than free with no/little support.
So, do you think, can we expect the guide anytime sooner? Although we should start our new projects with the latest framework, should we revert to the older version?
V2 documentation is out on the English site. It turns out there isn’t an English upgrade doc. I’ll translate the text from the Chinese doc and post it in this thread.
Hi Everyone! Particle system + .plist issue with v2.0.1
One of the bullet points for editor fixes in the v2.0.1 release notes states that " * Fixed issue with particle resource import in editor". I don’t know if I’m having that issue, but when I export a .plist and try to use it in another particle system via the particle file field, the new particle system always discards the texture information and generally populates different values for Duration, Emission Rate, Start Color Variation, and sometimes some of the other fields randomly as well. Hitting the sync button always puts a different value in the Emission Rate field than what is in the .plist.
Is there something I am doing wrong, or is this perhaps a bug?
The easiest way to verify this is to put the same number for every single field in a particle system and a Sprite frame. For example, the number 20. After exporting a .plist and loading that .plist into another particle system component, it can never find the texture and then the emission rate gets stamped on. Thanks for your time. Cheers, Greg
v2.0.2 has now been released. links above updated. I suggest everyone update to this release!

I am trying to resolve this error, but cant reach to a solution.
The project works till 1.9 v but from 2.0 this error comes.
And only in preview , in build there are different errors but they are solvable. ie in build this error doesnt comes.
