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.

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

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.

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.
