java - libGDX : How check if the actor exist on stage or not

Question

如何检查 Actor 是否被移除或不在舞台上？

像这样:

if(actor.isRemoved) {
   // enter code here
}

Answer 1

来自Documentation :

getStage

public Stage getStage() Returns the stage that this actor is currently in, or null if not in a stage.

所以你可以像这样使用它:

if(actor.getStage() == null) {
    //actor not on stage
}
