iPhone development--- cocos2D collision detection (ballistic path class) cocos2D really bad with the coordinate transformation, sprite.anchorPoint = ccp (0, 0) if not neatly shows the sprite.anchorPoint = ccp (0.5, 0.5) then, after the completion of collision detection, to go half-cell half-lattice. . . Collision objects that simply put the best pictures do little more than a little bit of the main collision with CGRect magicSquare ... cocos2D coordinate conversion so difficult to use, sprite.anchorPoint = ccp (0, 0) not neat if the display sprite.anchorPoint = ccp (0.5, 0.5) then, after the completion of collision detection, to go half-cell half-lattice. . .
