Corona SDK实现了球体在静态物体如墙壁上的逼真反弹效果。

我希望让球的弹跳更加逼真。有时候它会弹跳，达到最高点后逐渐减速，在触地后再次弹跳得更高。当球撞到墙上时，就像墙对球施加了一种力，而这不是我的本意（除了重力，它的默认设置是 y 方向上的 9.8 重力加速度），我没有对球施加任何力。

physics.addBody(bottomWall, "static", {density = 0, friction = 0, bounce = 0, isSensor = false})
physics.addBody(leftWall, "static", {density = 0, friction = 0, bounce = 0, isSensor = false})
physics.addBody(rightWall, "static", {density = 0, friction = 0, bounce = 0, isSensor = false})

local circle = display.newCircle( halfW, 20, 25 )
circle.x, circle.y = 160, -100
physics.addBody(circle, "dynamic", {bounce = 0.95})
