The animation state could not be played because it couldn't be found!

Question

Hi, trying to make a custom FPS player with self-made animations but when I use this code attached to the First Person Controller and press shift, it gives me the error in the question.

Here's the code I'm using, it references to animations in the Main Camera.

     childObject= GameObject.Find("Main Camera");
     if (ch.isGrounded && Input.GetKey("left shift") || Input.GetKey("right shift")){
         speed = runSpeed;
           childObject.animation.Play("fpsrun");
           }
           else {
           childObject.animation.Play("fpswalk");    
     }

Anyone know a quick fix for this? The animations are in the Assets folder. Do they need to be in a special folder somewhere? Also, they are attached to an animation tab in the inspector in Main Camera.

Any help? Thanks!

Your animations are not being found because they must be marked as legacy. Go to your project pane and select one of the animations (fpswalk or fpsrun). Then set the inspector to Debug Mode as shown in the photo attached. The animation type will probably be 2. Set it to 1. Repeat this step for your other animation(s).

Also, just for some debugging purposes, and cleaner code, try this as far as your script goes.

 #pragma strict
 
 private var childObject : GameObject;
 
 var walkSpeed: float = 7; // regular speed
 var crchSpeed: float = 3; // crouching speed
 var runSpeed: float = 20; // run speed
 
 private var chMotor: CharacterMotor;
 private var ch: CharacterController;
 private var height: float; // initial height
 
 var h : float;
 var speed : float;
 var lastHeight : float;
 
 var childAnim : Animation;
 
 function Start()
 {
     childObject = Camera.main.gameObject;
     childAnim = childObject.animation;
     chMotor = GetComponent(CharacterMotor);
     ch = GetComponent(CharacterController);
     height = ch.height;
     h = height;
     speed = walkSpeed;
 }
 
 function Update()
 {
     if(childAnim.GetClip("fpsrun") && childAnim.GetClip("fpswalk"))
     {
         if (ch.isGrounded && Input.GetKey(KeyCode.LeftShift) || Input.GetKey(KeyCode.RightShift))
         {
             speed = runSpeed;
             childObject.animation.CrossFade("fpsrun", 0.25f);
         }
         
         else
             childObject.animation.CrossFade("fpswalk", 0.25f);    
     }
     
     else print("Animations not found.");
     
     if (Input.GetKey(KeyCode.C))
     { // press C to crouch
         h = 0.5 * height;
         speed = crchSpeed; // slow down when crouching
     }
 
     chMotor.movement.maxForwardSpeed = speed; // set max speed
     ch.height = Mathf.Lerp(ch.height, h, 5*Time.deltaTime);
     lastHeight = ch.height; // crouch/stand up smoothly 
     transform.position.y += (ch.height-lastHeight)/2; // fix vertical position
 }

Glad I could help, I learned something new as well :D

Yeah, it removes the "jumpy" transition from fpswalk to fpsrun, looks way better than it was when it was animation.play!

Well, for example, if you're using W and S or Up and Down Arrows (Vertical Axis) to walk, you could do something like this:

 if(Input.GetAxis("Vertical") != 0)
 {
     if (ch.isGrounded && Input.Get$$anonymous$$ey($$anonymous$$eyCode.LeftShift) || Input.Get$$anonymous$$ey($$anonymous$$eyCode.RightShift))
     {
         speed = runSpeed;
         childObject.animation.CrossFade("fpsrun", 0.25f);
     }
 
     else
     {
         speed = walkSpeed;
         childObject.animation.CrossFade("fpswalk", 0.25f);   
     } 
 }

If you don't want to mark your animations as legacy, you can use the new Playables API to play non-legacy AnimationClips:

 private List<PlayableGraph> graphs = new List<PlayableGraph> ();
 
 // Just call this function when you want to play an AnimationClip on a specific GameObject.
 // from https://docs.unity3d.com/Manual/Playables-Examples.html
 private PlayableGraph playAnim(AnimationClip clip, GameObject obj) {
     PlayableGraph playableGraph;
 
     AnimationPlayableUtilities.PlayClip(obj.AddComponent<Animator>(), clip, out playableGraph);
 
     // save all graphs we create and destroy them at the end of our scene.
     // you might need to optimize this if you make a lot of animations.
     graphs.Add (playableGraph);
 
     return playableGraph;
 }
 
 void OnDisable() {
     foreach (var g in graphs) {
         g.Destroy();
     }
     graphs.Clear ();
 }

when changed to legacy, my animation inspector is all grayed out.
