电晕碰撞检测

Question

我有一系列定义如下的圆形对象：

local myBalloon = display.newImageRect("images/cracker.png", 20, 20);
myBalloon:setReferencePoint(display.CenterReferencePoint);
myBalloon.x = Random(50, _W-50);
myBalloon.y = (-10);
myBalloon.myName="balloon"
myBalloon.isSleepingAllowed = false;    
physics.addBody(myBalloon, "dynamic", {density=3.0, friction=1.0, bounce=0.0, radius=9});

然后我有一个可移动的对象，定义如下：

local threeWay = display.newImageRect("images/3way.png", 80, 43);
threeWay:setReferencePoint(display.CenterReferencePoint);
threeWay.x = (display.contentWidth / 2);
threeWay.y = (display.contentHeight -15);
threeWay.myName = "threeway"
pentagonShape = { -40,-5, 0,-22, 40,-5, 35,20, -35,20 }
physics.addBody(threeWay, "static", {density=4.0, friction=1.7, bounce=0.0, shape=pentagonShape});

我还为圆形对象设置了碰撞检测，如下所示：

function myBalloon:collision(e)
if (timeLeft ~= false) then
    if (playerReady == true) then
        if (e.phase == "ended") then
            if ( e.other.myName == "threeway" ) then
                audio.play(balloonPop);
                removeBalloons(self);
            end 
        end
    end
end
end

碰撞在很大程度上是起作用的，但有时圆形物体会落在可移动的物体上，并滚动一小段时间，然后由碰撞检测来处理。

如何为碰撞提供更即时的效果？对象的属性是否需要不同，以便在碰撞上有更多的“力”？

Answer 1

在气球上设置"isSensor“为"true”，这样就会触发你的碰撞功能，而不会发生颠簸、滚动等。
