CCDrawingPrimitives/CCDrawNode学习笔记

cocos2dx两种绘图方式：CCDrawingPrimitives和CCDrawNode。它们都在cocos2dxdraw_nodes目录下。

1. CCDrawingPrimitives（原生绘图）必须在节点的draw函数中调用:

void CC_DLL ccDrawPoint()
void CC_DLL ccDrawLine()

void CC_DLL ccDrawCubicBezier(const CCPoint& origin, const CCPoint& control1, const CCPoint& control2, const CCPoint& destination, unsigned int segments);

1. CCDrawNode（绘图节点）不需要在draw函数中调用，必须addChild才能在页面中显示

void drawPolygon(CCPoint *verts, unsigned int count, const ccColor4F &fillColor, float borderWidth, const ccColor4F &borderColor);
