我们知道,当我们移动时,我们会看到离我们越近的物体,会移动的越快,越远的物体,比如远处的山会移动的很慢,而最远处的物体,比如太阳几乎不动,这个现象叫视差,而在游戏中模仿视差,可以让玩家感觉到游戏中的角色的确是在移动。CCParallaxNode可以很容易的建立一个视差层,你可以控制每一层的视差率、位置和层级的高低。
local mapRes={ near=string.format("%s.%s",Resource_1.map.near.loc,Resource_1.map.near.rtype), middle=string.format("%s.%s",Resource_1.map.middle.loc,Resource_1.map.near.rtype), far=string.format("%s.%s",Resource_1.map.far.loc,Resource_1.map.near.rtype) } local MapParallaxNode=class("MapParallaxNode",function() return cc.ParallaxNode:create() end) MapParallaxNode.ctor=function(self) local s=cc.Director:getInstance():getVisibleSize() self._nearBg=nil self._middleBg=nil self._farBg=nil self._layerNode=nil self:initFarBg() self:initMiddleBg() self:initNearBg() self:setPosition(0,0) self:setAnchorPoint(cc.p(0,0)) self:addChild(self._farBg, -1, cc.p(0.03,0), cc.p(0,s.height+20)) self:addChild(self._middleBg, 1, cc.p(0.18,0), cc.p(5,s.height*2/3+90) ) self:addChild(self._nearBg, 2, cc.p(0.65,0), cc.p(0,s.height*2/3+40)) end --初始化地图近景 MapParallaxNode.initNearBg=function(self) local cache=cc.Director:getInstance():getTextureCache() local texture=cache:getTextureForKey(mapRes.near) local sprite=cc.Sprite:createWithTexture(texture) sprite:setPositionX(0) sprite:setScale(0.43) sprite:setAnchorPoint(cc.p(0,1)) self._nearBg=sprite end --初始化地图中景 MapParallaxNode.initMiddleBg=function(self) local cache=cc.Director:getInstance():getTextureCache() local texture=cache:getTextureForKey(mapRes.middle) local sprite=cc.Sprite:createWithTexture(texture) sprite:setScale(0.7) sprite:setAnchorPoint(cc.p(0,1)) self._middleBg=sprite end --初始化地图远景 MapParallaxNode.initFarBg=function(self) local cache=cc.Director:getInstance():getTextureCache() local texture=cache:getTextureForKey(mapRes.far) local sprite=cc.Sprite:createWithTexture(texture) sprite:setScale(0.4) sprite:setAnchorPoint(cc.p(0,1)) self._farBg=sprite end MapParallaxNode.create=function(self) return MapParallaxNode.new() end return MapParallaxNode
CCParallaxNode添加视差精灵的函数:
self:addChild(self._farBg, -1, cc.p(0.03,0), cc.p(0,s.height+20)) self:addChild(self._middleBg, 1, cc.p(0.18,0), cc.p(5,s.height*2/3+90) ) self:addChild(self._nearBg, 2, cc.p(0.65,0), cc.p(0,s.height*2/3+40))parallaxRatio是设置不同层的x,y移动速度 |
