打开和关闭特定对象的物理

Question

我怎样才能打开和关闭＆＃34; physics.addBody＆＃34;在我的＆＃34;酒吧＆＃34;对象

如果我尝试：

physics.pause(bar, "static", {density=.1, bounce=.5, friction=.2,filter=barCosllisionFilter } ) 

所有物理暂停

bar object：

bar = display.newSprite( BARimageSheet, BARsequenceData1)
bar.x = display.contentWidth/2
bar.y = display.contentHeight/2
bar:play()
bar.collided = true
bar.name = "bar"
bar.gravityScale = 0.0 
physics.addBody(bar, "static", {density=.0, bounce=.5, friction=.2,filter=barCosllisionFilter } )           
bar.isVisible = true-- false
bar.isFixedRotation=true
screenGroup:insert(bar)

Answer 1

尝试将其关闭：

--change the bar body's active state to false
bar.isBodyActive = false

要再次启用它，只需将属性设置为true即可。
