传递给Actor.addBehavior的行为类为null。超级大国

Question

Superpowers游戏引擎。

打字稿。

游戏脚本

let MainChar = new Sup.Actor("Main Character");
new Sup.SpriteRenderer(MainChar, "Leonard");

let CameraMan = new Sup.Actor("Camera Man");
new Sup.Camera(CameraMan);

MainChar.setPosition(0, 0, 0);
CameraMan.setPosition(0, 0, 5);

MainChar.addBehavior(CharacterBehavior);

字符脚本

class CharacterBehavior extends Sup.Behavior {
 update() {
  if(Sup.Input.isKeyDown("LEFT")){
   this.actor.move(-0.1, 0, 0);
 }

  if(Sup.Input.isKeyDown("RIGHT")){
   this.actor.move(0.1, 0, 0);
  }
 }
 }
Sup.registerBehavior(CharacterBehavior);

如何修复？我是TypeScript的新手，并且使用了“export”和“import”，但它不起作用。

Answer 1

为什么您的import { CharacterBehavior } ...已注明？
