Actor class, also known as actor class, is the most basic element in LIBGDX development and can be inherited. Actor class, from the perspective of OpenGL class, can be called a two-dimensional scene node. It itself has a common approach to properties such as position (postion), bounding rectangle (similar to retangle), Anchor point (Origin), scaling (scale), rotation (rotation), color, and so on: Act (float Delta) : Update the state of the actors in the game, often called in render, parameters are generally passed into the game render interval time. Addaction (Action action): Adding an action, adding a simple animation to the actor Addcapturelistener (EventListener listener): Adding a Capture listener, an object passed in as an event listener , which is used to listen for events during capture. AddListener (EventListener Listener): Add Listener Clear (): Empties all listeners added by the current actor Clearlisteners (): Empties all listeners added by the current actor Clipbegin () : Crop current actor clipbegin (float x,float y,float width,float height): Crop current actor based on incoming rectangle clipend (): End cropping debug (): Debug method Draw (Batch batch , float Parentalpha): Draw Current actor Fire (event event): Sets the current actor as the event target actor, if necessary, passes the event in the argument to the parent of the current actor getactions (): Gets all the actions that are added to the current actor, The return type is a list-type variable getcolor (): Gets the current color Getdebug (): The return type is a Boolean variable that confirms whether the actor has been debugged GetHeight (): Gets the height of the actor getlisteners () : Gets all listeners currently added, return type is a list type variable getname (): Gets the name of the current actor, mates with SetName (String name) using
