Physics 在经过replaceScene更新当前界面后， 会出现重复碰撞的问题

Cocos2d-x Lua
#1

已经解决

在onExit 时，
c.Director:getInstance():getEventDispatcher():removeEventListener(self.contactListener)

  1. 可以把下面代码建立一个Scene , 然后观察print(“log…”)

当球第一次与方块接触时， 每次接触， 打印一次 log …

  1. 然后点击Restart

这时可以明显看出来， 球与方块接触时， 每次打印两次 log …

这个情况怎么解决？？

补充： quick-cocos2d-x 3.2rc1 ,3.3rc1 都有这个问题

local c = cc
local roleCtrl = require("app.controller.roleCtrl")

local RoleTestScene = class("RoleTestScene", function()
    return display.newPhysicsScene("GameScene")
end)



function RoleTestScene:ctor()
    self.world= self:getPhysicsWorld()
    self.world:setGravity(c.p(0,-100))
    self.world:setDebugDrawMask(cc.PhysicsWorld.DEBUGDRAW_ALL)




        -- 碰撞监听处理...... 
    self.contactListener = c.EventListenerPhysicsContact:create()
    self.contactListener:registerScriptHandler(handler(self,self.onContactBegin), c.Handler.EVENT_PHYSICS_CONTACT_BEGIN)
    local eventDispathcher = c.Director:getInstance():getEventDispatcher()
    eventDispathcher:addEventListenerWithFixedPriority(self.contactListener, 1)


end

function RoleTestScene:onEnter()


    -- 盒子.... 
    local box = display.newRect(cc.rect(display.cx , display.cy, display.width , display.height) , 
        {fillColor = cc.c4f(0,0,0,1), borderColor = cc.c4f(0,1,0,1), borderWidth = 1} )

    :align(display.CENTER , display.cx , display.cy )
    local boxBody = c.PhysicsBody:createEdgeBox(c.size(display.width-100 , display.height -100 ))
    boxBody:setCategoryBitmask(0x01)
    boxBody:setContactTestBitmask(0x05)
    box:setPhysicsBody(boxBody)
