Function Documentation

invalidateStateCache()

void cocos2d::GL::invalidateStateCache

(

void

)

Invalidates the GL state cache.

If CC_ENABLE_GL_STATE_CACHE it will reset the GL state cache.

Since

v2.0.0

useProgram()

void cocos2d::GL::useProgram

(

GLuint

program

)

Uses the GL program in case program is different than the current one.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will the glUseProgram() directly.

Since

v2.0.0

deleteProgram()

void 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

blendFunc()

void cocos2d::GL::blendFunc	(	GLenum	sfactor,
		GLenum	dfactor
	)

Uses a blending function in case it not already used.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will the glBlendFunc() directly.

Since

v2.0.0

blendResetToCache()

void 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

setProjectionMatrixDirty()

void cocos2d::GL::setProjectionMatrixDirty

(

void

)

Sets the projection matrix as dirty.

Since

v2.0.0

enableVertexAttribs()

void cocos2d::GL::enableVertexAttribs

(

uint32_t

flags

)

Will enable the vertex attribs that are passed as flags.

Possible flags:

• VERTEX_ATTRIB_FLAG_POSITION
• VERTEX_ATTRIB_FLAG_COLOR
• VERTEX_ATTRIB_FLAG_TEX_COORDS

These flags can be ORed. The flags that are not present, will be disabled.

Since

v2.0.0

bindTexture2D() [1/2]

void 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

bindTexture2D() [2/2]

void cocos2d::GL::bindTexture2D

(

Texture2D *

texture

)

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.

Remarks

: It will bind alpha texture to support ETC1 alpha channel.

Since

v3.13

bindTexture2DN()

void cocos2d::GL::bindTexture2DN	(	GLuint	textureUnit,
		GLuint	textureId
	)

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

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

Since

v2.1.0

bindTextureN()

void cocos2d::GL::bindTextureN	(	GLuint	textureUnit,
		GLuint	textureId,
		GLuint	textureType = GL_TEXTURE_2D
	)

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

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

Since

v3.6

deleteTexture()

void 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

deleteTextureN()

void 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

activeTexture()

void cocos2d::GL::activeTexture

(

GLenum

texture

)

Select active texture unit.

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

Since

v3.0

bindVAO()

void 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
