- This is part of 01219245.
This guide is very short. It only discuss various techniques in implementing platform games.
Here are a few useful links:
- The guide to implementing 2D platformers by Rodrigo Monteiro.
- Sonic Physics Guide

Collision detection: cc.Rect
Previously, we have implemented our own collision detection routine. However, Cocos2d-html5 has provided us with a few nice collision detection tools. See code here.
Related functions are:
- Creation: cc.rect
- Accessing functions: cc.rectGetMaxX, cc.rectGetMidX, cc.rectGetMinX, cc.rectGetMaxY, cc.rectGetMidY, cc.rectGetMinY
- Testing:
- cc.rectEqualToRect
- cc.rectContainsRect
- cc.rectContainsPoint
- cc.rectIntersectsRect
- cc.rectOverlapsRect
- Manipulation:
- cc.rectUnion
- cc.rectIntersection
