As in cocos2d to draw a triangle with vertices in different colors???

cocos2d-x C++
#1

Hi! I really need your help! Tell me, how do I draw a triangle on CCRenderTexture with colored tops? I tried to override the ccDrawSolidPoly to be output with the ground and the triangle with colored tops.
`void ccDrawSolidPoly( const CCPoint *poli, unsigned int numberOfPoints, ccColor4F color, int w )
{

lazy_init();


s_pShader->use();
s_pShader->setUniformForModelViewProjectionMatrix();    
s_pShader->setUniformLocationWith4fv(s_nColorLocation, (GLfloat*) &color.r, 1);

ccGLEnableVertexAttribs( kCCVertexAttribFlag_Position );

// XXX: Mac OpenGL error. arrays can't go out of scope before draw is executed
ccVertex2F* newPoli = new ccVertex2F[numberOfPoints];

// iPhone and 32-bit machines optimization
if( sizeof(CCPoint) == sizeof(ccVertex2F) )
{
    glVertexAttribPointer(kCCVertexAttrib_Position, 2, GL_FLOAT, GL_FALSE, 0, poli);
}
else
{
    // Mac on 64-bit
    for( unsigned int i=0; i<numberOfPoints;i++)
    {
        newPoli[i] = vertex2( poli[i].x, poli[i].y );
    }
    glVertexAttribPointer(kCCVertexAttrib_Position, 2, GL_FLOAT, GL_FALSE, 0, newPoli);
}    
glDrawArrays(GL_TRIANGLE_FAN, 0, (GLsizei) numberOfPoints); 
///////////////////////////////////////////////////////////////////////////////////
glPolygonMode(GL_FRONT_AND_BACK, GL_FILL);
glBegin(GL_TRIANGLES);
glColor3d(1,0,0);      // рисуем треугольник
glVertex3d(0,0,0);
glVertex3d(700,700.9,0);
glVertex3d(200,200,0);
glEnd();
///////////////////////////////////////////////////////////////////////////////////
CC_SAFE_DELETE_ARRAY(newPoli);
CC_INCREMENT_GL_DRAWS(1);

}` But in the end I got one color triangle, the color that matches the color of the polygon. How can I be? (sorry for my english :))
