POHow to get cocos2d to draw all rectangles in an array

Body
copied!<p>How can I draw all the rectangles in a CGRect array? The code I have so far is: in my init method:</p> <blockquote> <p><code>rec1 = CGRectMake(50, 400, 30, 30);</code><br> <code>CGRect startingRect = rec1;</code><br> <code>int count = 48;</code><br> <code>CGRect rectArray[count];</code><br> <code>rectArray[0] = startingRect;</code><br> <code>CGRect oneRect = rectArray[0];</code><br> <code>int i;</code><br> <code>for (i = 1; i < count; i++) {</code><br> <code>oneRect.origin.x += 40;</code><br> <code>if (oneRect.origin.x+oneRect.size.width > size.width) {</code><br> <code>oneRect.origin.x = startingRect.origin.x;</code><br> <code>oneRect.origin.y -= 40;</code><br> <code>}</code><br> <code>rectArray[i] = oneRect;</code><br> <code>}</code><br> <code>[self draw];</code> </p> </blockquote> <p>in my draw method:</p> <blockquote> <p><code>glColor4f(1.0, 0, 0, 1.0);</code><br> <code>glLineWidth(1.0f);</code><br> <code>[self drawRectange:rec1];</code> </p> </blockquote> <p>and in my drawRectangle method:</p> <blockquote> <p><code>glColor4f(1.0, 0.0, 0.0, 1.0);</code><br> <code>CGPoint vertices[4] = {</code><br> <code>ccp(rect.origin.x, rect.origin.y),</code><br> <code>ccp(rect.origin.x+rect.size.width, rect.origin.y),</code><br> <code>ccp(rect.origin.x+rect.size.width, rect.origin.y+rect.size.height),</code><br> <code>ccp(rect.origin.x, rect.origin.y+rect.size.height)</code><br> <code>};</code><br> <code>ccDrawPoly(vertices, 4, YES);</code><br> <code>glVertexPointer(2, GL_FLOAT, 0, vertices);</code><br> <code>CC_ENABLE_DEFAULT_GL_STATES();</code> </p> </blockquote> <p>The problem is, since the draw method overrides the original (at least thats what i think it does), i can't modify it to accept a CGRect parameter so it can send a message to the drawRentangle method for each rect. Can someone please help me? Many thanks.</p>
