Question

I’m trying to draw a simple colored circle on the screen with cocos2d, but everything I draw comes out white.
I tried glColor4f and glColor4ub but neither one works, even though they were used here to draw colored primitives: http://code.google.com/p/cocos2d-iphone/source/browse/trunk/tests/drawPrimitivesTest.m?r=1813

These are examples straight out of their code, but it’s just giving me a white circle and a white line.

-(void) draw
{
    [super draw];
    glEnable(GL_LINE_SMOOTH);

    glColor4f(0.0, 1.0, 0.0, 1.0);
    glLineWidth(2.0f);
    ccDrawLine(ccp(10,100),ccp(50,79));

    glLineWidth(16);
    glColor4ub(0, 255, 0, 255);
    ccDrawCircle( ccp(200,  200), 100, 0, 10, NO);

}

Answer 1

cocos2d 2.0 uses OpenGLES 2.0. glColor4f no longer exists. To change the draw color you can use

ccDrawColor4F(0.0f, 1.0f, 0.0f, 1.0f);
