下面是main.lua文件的完整代码，单击屏幕任意一点会创建一个精灵，精灵之间相互碰撞后产生回调事件。

local MainScene = class ("MainScene",function()
    return display.newScene("MainScene",{physics = 2})
end)

function MainScene:ctor()
    self:getPhysicsWorld():setGravity(cc.p(0,-100))    --重力
    self:getPhysicsWorld():setDebugDrawMask(cc.PhysicsWorld.DEBUGDRAW_ALL)
    local size = display.size
    local body = cc.PhysicsBody:createEdgeBox(size,cc.PHYSICSBODY_MATERIAL_DEFAULT,2)
    local edgeNode = display.newNode()
    edgeNode:setPosition(size.width/2,size.height/2)
    edgeNode:setPhysicsBody(body)
    self:addChild(edgeNode)
    --监听碰撞
    local function onContactBegin(contact)
        local tag = contact:getShapeA():getBody():getNode():getTag()
        -- print(tag)     --碰撞后的回调事件
        return true
    end

    local contactListener = cc.EventListenerPhysicsContact:create()
    contactListener:registerScriptHandler(onContactBegin,cc.Handler.EVENT_PHYSICS_CONTACT_BEGIN)
    local eventDispatcher = cc.Director:getInstance():getEventDispatcher()
    eventDispatcher:addEventListenerWithFixedPriority(contactListener,1)

self:getPhysicsWorld():setDebugDrawMask(cc.PhysicsWorld.DEBUGDRAW_ALL)
    local function onTouchBegan( touch, event )
        return true  
    end
    local function onTouchEnded( touch, event )
        local location = touch:getLocation()   --获取鼠标的位置
        local event_x = location["x"] or 0      
        local event_y = location["y"] or 0
        self:addSprite(event_x,event_y)
    end
    local function onTouchMoved(touch, event)
    end
    local listener1 = cc.EventListenerTouchOneByOne:create()  --创建一个单点事件监听
    listener1:setSwallowTouches(false)  --是否向下传递
    listener1:registerScriptHandler(onTouchBegan,cc.Handler.EVENT_TOUCH_BEGAN )
    listener1:registerScriptHandler(onTouchMoved,cc.Handler.EVENT_TOUCH_MOVED )
    listener1:registerScriptHandler(onTouchEnded,cc.Handler.EVENT_TOUCH_ENDED )
    local eventDispatcher = self:getEventDispatcher() 
    eventDispatcher:addEventListenerWithSceneGraphPriority(listener1, self) --分发监听事件
end
function MainScene:addSprite(x,y)
    local oneSprite = display.newSprite("game/basketball/image/basketball.png")
    -- local oneBody = cc.PhysicsBody:createBox(oneSprite:getContentSize(),cc.PHYSICSBODY_MATERIAL_DEFAULT,cc.p(0,0))  --矩形刚体
    local oneBody = cc.PhysicsBody:createCircle(25,cc.PHYSICSBODY_MATERIAL_DEFAULT,cc.p(0,0))      --圆形刚体   
    oneBody:setContactTestBitmask(0xFFFFFFFF)
    oneBody:applyImpulse(cc.p(0,10000))
    oneSprite:setPhysicsBody(oneBody)
    oneSprite:setPosition(x,y)
    oneSprite:setTag(101)
    self:addChild(oneSprite)
end


function MainScene:showWithScene(transition, time, more)
    self:setVisible(true)
    local scene = self
    display.runScene(scene, transition, time, more)
    return self
end

return MainScene

效果图如下
