Question

我想在点击一个对象时调用removeBody函数。我一点击必须在对象上调用removeBody函数的对象，并在我释放之后鼠标然后它必须再次像物理对象一样。这些是我的代码尝试着。请提出任何建议

local function removephysics(objId)
   physics.removeBody(objId)
end

local Bodyobject={density=3.0, friction=0.2, bounce=0.3, radius=20}

object1=display.newImage("img1.png")
object1.x=325
object1.y=200
object1.id="obj"
physics.addBody(object1,Bodyobject)
object1.addEventListener("touch",removephysics)

Answer 1

您可以使用event.phase来获取触摸侦听器的状态，并查看此代码

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

local Bodyobject={density=3.0, friction=0.2, bounce=0.3, radius=20}
function removephysics(event)
   if event.phase == "began" then
      physics.removeBody(object1)
   elseif event.phase == "ended" then
      physics.addBody(object1,Bodyobject)
   end
end


object1=display.newImage("img1.png")
object1.x=325
object1.y=200
object1.id="obj"
physics.addBody(object1,Bodyobject)
object1:addEventListener("touch",removephysics)

如何在电晕的触摸事件中动态调用物理的removeBody函数
