Function Documentation

void CC_DLL
cocos2d::GL::deleteProgram
( GLuint  program)

Deletes the GL program.

If it is the one that is being used, it invalidates it. If CC_ENABLE_GL_STATE_CACHE is disabled, it will the glDeleteProgram() directly.

Since
v2.0.0
var deleteProgram ( var  program)

Deletes the GL program.

If it is the one that is being used, it invalidates it. If CC_ENABLE_GL_STATE_CACHE is disabled, it will the glDeleteProgram() directly.

Since
v2.0.0
local deleteProgram ( local  program)

Deletes the GL program.

If it is the one that is being used, it invalidates it. If CC_ENABLE_GL_STATE_CACHE is disabled, it will the glDeleteProgram() directly.

Since
v2.0.0
void CC_DLL
cocos2d::GL::blendResetToCache
( void  )

Resets the blending mode back to the cached state in case you used glBlendFuncSeparate() or glBlendEquation().

If CC_ENABLE_GL_STATE_CACHE is disabled, it will just set the default blending mode using GL_FUNC_ADD.

Since
v2.0.0
var blendResetToCache (   )

Resets the blending mode back to the cached state in case you used glBlendFuncSeparate() or glBlendEquation().

If CC_ENABLE_GL_STATE_CACHE is disabled, it will just set the default blending mode using GL_FUNC_ADD.

Since
v2.0.0
local blendResetToCache (   )

Resets the blending mode back to the cached state in case you used glBlendFuncSeparate() or glBlendEquation().

If CC_ENABLE_GL_STATE_CACHE is disabled, it will just set the default blending mode using GL_FUNC_ADD.

Since
v2.0.0
void CC_DLL
cocos2d::GL::setProjectionMatrixDirty
( void  )

sets the projection matrix as dirty

Since
v2.0.0
var setProjectionMatrixDirty (   )

sets the projection matrix as dirty

Since
v2.0.0
local setProjectionMatrixDirty (   )

sets the projection matrix as dirty

Since
v2.0.0
void CC_DLL
cocos2d::GL::bindTexture2D
( GLuint  textureId)

If the texture is not already bound to texture unit 0, it binds it.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glBindTexture() directly.

Since
v2.0.0
var bindTexture2D ( var  textureId)

If the texture is not already bound to texture unit 0, it binds it.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glBindTexture() directly.

Since
v2.0.0
local bindTexture2D ( local  textureId)

If the texture is not already bound to texture unit 0, it binds it.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glBindTexture() directly.

Since
v2.0.0
void CC_DLL
cocos2d::GL::deleteTexture
( GLuint  textureId)

It will delete a given texture.

If the texture was bound, it will invalidate the cached. If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glDeleteTextures() directly.

Since
v2.0.0
var deleteTexture ( var  textureId)

It will delete a given texture.

If the texture was bound, it will invalidate the cached. If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glDeleteTextures() directly.

Since
v2.0.0
local deleteTexture ( local  textureId)

It will delete a given texture.

If the texture was bound, it will invalidate the cached. If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glDeleteTextures() directly.

Since
v2.0.0
void CC_DLL
cocos2d::GL::deleteTextureN
( GLuint  textureUnit,
GLuint  textureId 
)

It will delete a given texture.

If the texture was bound, it will invalidate the cached for the given texture unit. If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glDeleteTextures() directly.

Since
v2.1.0
var deleteTextureN ( var  textureUnit,
var  textureId 
)

It will delete a given texture.

If the texture was bound, it will invalidate the cached for the given texture unit. If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glDeleteTextures() directly.

Since
v2.1.0
local deleteTextureN ( local  textureUnit,
local  textureId 
)

It will delete a given texture.

If the texture was bound, it will invalidate the cached for the given texture unit. If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glDeleteTextures() directly.

Since
v2.1.0
void CC_DLL cocos2d::GL::bindVAO ( GLuint  vaoId)

If the vertex array is not already bound, it binds it.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glBindVertexArray() directly.

Since
v2.0.0
var bindVAO ( var  vaoId)

If the vertex array is not already bound, it binds it.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glBindVertexArray() directly.

Since
v2.0.0
local bindVAO ( local  vaoId)

If the vertex array is not already bound, it binds it.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glBindVertexArray() directly.
