Question

我试图在模拟器上检测动态对象与静态对象的碰撞，但不能在设备上检测。

在createScene上我创建了对象：

b1 = display.newRect( 50, 80, 140, 140 )
b1:setFillColor( 49/255, 179/255, 173/255 )
b1.anchorX = 0.0
b1.anchorY = 0.0
physics.addBody( b1, "static", { density = 1.0, friction = 0.3, bounce = 0.2 }  )

b1:addEventListener( "collision", onCollision )  


playerBox = display.newRect( display.contentCenterX - 55, display.contentCenterY - 55, 110, 110 )
playerBox:setFillColor( 241/255, 76/255, 0/255 )
playerBox.anchorX = 0.0
playerBox.anchorY = 0.0
playerBox:addEventListener( "touch", onTouch )
physics.addBody( playerBox, "dynamic", { friction=0.3, isSensor=true } )

playerBox:addEventListener( "collision", onCollision )

group:insert( b1 )

group:insert( playerBox )

听众：

local function onCollision( event )
    if ( event.phase == "began" ) then
      gameOver() 
    elseif ( event.phase == "ended" ) then  
    end
end

函数gameOver（）从未调用过设备。

请帮忙吗？

您需要物理，然后在添加物理实体之前调用physics.start()。并且你的物理实体必须对齐，以便它们实际碰撞。这里修改了代码：

local physics = require("physics")
physics.start()

local group = display.newGroup()

local function onTouch()
    print("touched")
end

local function gameOver()
    print("gameover")
end

local function onCollision( event )
    if ( event.phase == "began" ) then
      gameOver() 
    elseif ( event.phase == "ended" ) then  
    end
end

b1 = display.newRect(  display.contentCenterX - 50,display.contentCenterY, 140, 140 )
b1:setFillColor( 49/255, 179/255, 173/255 )
b1.anchorX = 0.0
b1.anchorY = 0.0
physics.addBody( b1, "static", { density = 1.0, friction = 0.3, bounce = 0.2 }  )
b1:addEventListener( "collision", onCollision )  

playerBox = display.newRect( display.contentCenterX - 55, display.contentCenterY - 150, 110, 110 )
playerBox:setFillColor( 241/255, 76/255, 0/255 )
playerBox.anchorX = 0.0
playerBox.anchorY = 0.0
playerBox:addEventListener( "touch", onTouch )
physics.addBody( playerBox, "dynamic", { friction=0.3, isSensor=true } )

playerBox:addEventListener( "collision", onCollision )

group:insert( b1 )

group:insert( playerBox )

我还添加了您可能已经拥有的缺失函数，只是为了能够运行代码。请记住，playerBox是一个传感器，因此不会发生碰撞反应，其他物体只会通过它。
