为什么我在 Unity 编辑器 window 中的输入工作正常，但在游戏构建中却完全没有？

Question

I have a pretty simple script:

 void Start()
 {
 }
 void Update()
 {
     if (Input.GetKeyDown("return")){
         play();
     }
 }
 void play()
 {
     anim.SetTrigger("playbutton");
 }

It works wonders in the editor window, but when I build and run, absolutely nothing happens. It loads the scene just fine, but the button inputs don't seem to be getting through.

UPDATE: I tried several different buttons, but those didn't work. I did try putting the anim.SetTrigger line in the Start function, and it didn't work either, which means that this is a problem with the animator/script, not the input.

Answer 1

the script seems simple and fine, i suggest that u try the same script in an empty project to see if it works or not if it dose work try to apply the script on an other game object and run. lets say it didn't work u can try this instead "if (Input.GetKeyDown(KeyCode.Return)" or try to use an other key

Answer 2

I'VE FOUND IT. The animation component in the object in question was set to cull completely, not always animate.
