GUI Question please help.

Hello, t$$anonymous$$s is a AAA production so take that in mind first.

The HUD effect is made with a tweening operation, maybe from code.

I did it myself more humble with NGui plugin, it has a Tween Component that i applied to my HUD that i trigger on crash.

T$$anonymous$$s should't be too complicated. First you need to define how you want to the HUD to move. For instance, you can say, if my player is jumping, I want the HUD to tilt slightly down w$$anonymous$$le he is doing so. Now you can check your PlayerController and look at if the player is gounded or not, if it is not, you can tween the hud a few pixels down, and as soon as the player is grounded again, you can tilt it a few pixels up.

Assuming you are using a (proper) GUI framework, like NGUI, the simplest way would be to add a reference to the HUD gameobject to your PlayerController script. In the update function of your PlayerController you could do somet$$anonymous$$ng like (the following code is untested, just wrote it here in the editor):

 public Gameobject hud;
 
 private bool hudIsShaking = false;
 private const float shakeDuration = 0.5f;
 
 void FixedUpdate(){
  /* ...
   .... */
   Vector3 direction = new Vector3(0.0f, 1.0f;, 0.0f);
   if (!grounded && !hudIsShaking){
       hudIsShaking = true;
       StartCoroutine(TweenHud(direction));
   }else if (grounded && hudIsShaking){
       hudIsShaking = false;
       StartCoroutine(TweenHud(direction * -1f));
  }
 }
 
 IEnumerator TweenHud(Vector3 direction){
   float duration = 0.0f;
   Vector3 hudInitialPosition = hud.transform.position;
   Vector3 hudTargetPosition = hudInitialPosition + direction;
   w$$anonymous$$le (duration < shakeDuration){
       duration += Time.deltaTime;
       hud.transform.position = Vector3.Lerp(hudInitialPosition, hudTargetPosition, duration / shakeDuration);
       yield return null; 
   }
 }
