reduce the 3D effect when only using 2D feature

[drelaptop]

• cocos2d-x version:3.17

for not any members in cocos2d-x team to maintain the 3D feature yet

-----------updated--------

Thanks for feedback, what we should do is to reduce the 3D effect when only using 2D feature, NOT remove 3D

3D features works great in cocos, why to remove them?

[drelaptop]

thanks for telling this.

some developers only using 2D feature in cocos2d-x, hold a idea that 3D have a bad effect on 2D performance.

@drelaptop What kind of bad effect do you say now? Can you give more details?

[Dimon4eg]

I think it's mostly compile time and binary size.

In ccConfig.h there are config defines for physics:
CC_USE_PHYSICS
CC_USE_3D_PHYSICS

For 2D game would be good to cut off 3D part also.

[gestern]

Good idea!

[umitgoren]

It should be improved in v4. Why should we use Unity3D?

[Dimon4eg]

@umitgoren Unity3D?

[umitgoren]

@Dimon4eg If 3D is removed some Cocos2d-x users will prefer Unity3D for its advanced 3D features.

[Dimon4eg]

No, I propose to add define to ccConfig.h for 3D part of engine.
If define is 0 then 3D part is disabled.

@gestern another possible reason is about the performance, the cocos2d-x without 3D added own a better performance than cocos2d-x with 3D added, when only use 2D feature. This need to be tested and proved, I can't make sure.

thanks @Dimon4eg , we should reduce the 3D effect when only using 2D feature in deed.

I'm disposed to agree with @Dimon4eg , add define to ccConfig.h for 3D part of cocos2d-x.

#define CC_USE_3D 0

And as I know, some guys are developing 3D for Creator. So please do not remove the 3D of cocos2d-x but add 3D to Creator.
