Cocos2dx_世界坐标和模型坐标

1、世界坐标转成模型坐标

	--Node1
	local node1 = cc.Sprite:create("res/common/node1.png")
	node1:setAnchorPoint(cc.p(1.0, 1.0))
	node1:setPosition(cc.p(400, 500))
	self.panel.layer:addChild(node1)

	--Node2
	local node2 = cc.Sprite:create("res/common/node2.png")
	node2:setAnchorPoint(cc.p(0.5, 0.5))
	node2:setPosition(cc.p(200, 300))
	self.panel.layer:addChild(node2)

	local x, y = node2:getPosition()
	local pt1 = node1:convertToNodeSpace(cc.p(x,y))

	cclog("Node2 NodeSpace = (%f, %f)", pt1.x, pt1.y)
	cclog("Node2 NodeSpaceAR = (%f, %f)", pt2.x, pt2.y)	--Node1
	local node1 = cc.Sp
