bool HelloWorld::init()

CCSprite sprite = CCSprite::create;

}

#ifdef GL_ES
precision mediump float;
#endif

// 1
attribute vec4 vPosition;

void main()
{ // 2

gl_Position = vPosition;
}
#ifdef GL_ES
precision mediump float;
#endif

// 1
varying vec2 v_texCoord;
uniform sampler2D u_texture;
uniform sampler2D u_colorRampTexture;

void main()
{ // 2

gl_FragColor = vec4(0, 0, 0, 1);
}

why run wrong

#2

What is wrong with it? Did you forget to link/activate the shader program?

@ glProgram~~>link;
glProgram~~>updateUniforms();
glProgram->use();@
