Cocos2D 2.0 - 数以百万计的OpenGL错误 [英] Cocos2D 2.0 - Zillions of OpenGL errors

问题描述

我将Cocos2D项目转换为2.0。

我使用Cocos2D 2.0模板（无物理的简单模板）创建了一个空白项目，

我编译，我看到了没有错误。我运行应用程序，它似乎正确运行，但我有控制台上的这些错误...

正如我所说，这是从一个空白模板创建的。

如何解决这个问题？

解决方案

OpenGL错误0x506 = GL_INVALID_FRAMEBUFFER_OPERATION

Cocos2D 2.0和Cocos2D 1.0之间的主要区别是OpenGLES版本。 Cocos2D 2.0使用OpenGLES 2.0，Cocos2D 1.0使用OpenGLES 1.0。

我想你可以使用在OpenGLES 1.0中找不到的API。

示例：GLBegin（），GLLineWidth（）等

使用此绘制函数：

   - （void）draw 
 {
 [super draw]; 
 ccGLEnableVertexAttribs（kCCVertexAttribFlag_Position）; 
 kmGLPushMatrix（）; 
 self.world-> DrawDebugData（）; 
 kmGLPopMatrix（）; 
} 
  

而不是这样：

   - （void）draw 
 {
 glDisable（GL_TEXTURE_2D）; 
 glDisableClientState（GL_COLOR_ARRAY）; 
 glDisableClientState（GL_TEXTURE_COORD_ARRAY）; 
 
 world-> DrawDebugData（）; 
 
 //恢复默认GL状态
 glEnable（GL_TEXTURE_2D）; 
 glEnableClientState（GL_ColOR_ARRAY）; 
 glEnableClientState（GL_TEXTURE_COORD_ARRAY）; 
 
} 
  

也可以使用GLES-Render.h和GLES-Render。 m从Cocos2D 2.0

I am transposing a Cocos2D project to 2.0.

I have created a blank project using Cocos2D 2.0 template (the simple template without physics) and transferred all files from the old project to the blank project.

I have also converted that to ARC.

I compile and I see no errors. I run the app and it appears to be running correctly, but I have these errors on console...

As I said, this was created from a blank template.

how do I fix that?

解决方案

OpenGL error 0x506 = GL_INVALID_FRAMEBUFFER_OPERATION

Main difference between Cocos2D 2.0 and Cocos2D 1.0 is OpenGLES version. Cocos2D 2.0 uses OpenGLES 2.0 and Cocos2D 1.0 uses OpenGLES 1.0.

I guess you may used API that is not found in OpenGLES2.0 that found in OpenGLES 1.0

Example:GLBegin(), GLLineWidth() etc

Use this draw function:

-(void) draw
{
    [super draw];
    ccGLEnableVertexAttribs( kCCVertexAttribFlag_Position );
    kmGLPushMatrix();
    self.world->DrawDebugData();    
    kmGLPopMatrix();
}

Instead of this:

-(void) draw
{
    glDisable(GL_TEXTURE_2D);
    glDisableClientState(GL_COLOR_ARRAY);
    glDisableClientState(GL_TEXTURE_COORD_ARRAY);

    world->DrawDebugData();

    // restore default GL states
    glEnable(GL_TEXTURE_2D);
    glEnableClientState(GL_COLOR_ARRAY);
    glEnableClientState(GL_TEXTURE_COORD_ARRAY);

}

Also use GLES-Render.h and GLES-Render.m from Cocos2D 2.0
