Basic Script Doesn't Work.

I have an object in my game which needs to move back and forward.

This is my script:

Code (JavaScript):

1.  
2. function Start () {
3.     InvokeRepeating("PlayAnims", 0, 2);
4. }
5.  
6. function PlayAnims () {
7.     animation.CrossFade("Back");
8.     yield WaitForSeconds (1);
9.     animation.CrossFade("Forward");
10.     yield WaitForSeconds (1);
11. }

But this doesn't do anything. I don't get errors and the object won't move.
Please help

 

Did you make sure that all the parts in the code are reached repeatedly, e.g. by placing some Debug.Logs?

 

I don't understand why this won't work.

 

I don't understand it too. That's why we need to find out what is going on. Place some Debug.Log ("..."); in your code, such that you see what is actually being executed. Knowing that the code is actually being executed is the first step to isolate the issue.

 

I did this:

Code (JavaScript):

1.  
2. function Start () {
3.     InvokeRepeating("PlayAnims", 0, 2);
4. }
5.  
6. function PlayAnims () {
7.     Debug.Log("Play Back Animation");
8.     //animation.CrossFade("Back");
9.     yield WaitForSeconds (1);
10.     Debug.Log("Play Back Animation");
11.     //animation.CrossFade("Forward");
12.     yield WaitForSeconds (1);
13. }

Nothing printed to the console...

 

put the script on the object that you want to animate.
Also put #pragma strict at the top of your code.

 

It might be that invoke repeating doesn't like coroutines. You may try this instead:

Code (csharp):

1. function Start () {
2.   StartCoroutine (PlayAnims ());
3. }
4. function PlayAnims () {
5.   while (true) {
6.   Debug.Log("Play Back Animation");
7.   //animation.CrossFade("Back");
8.   yield WaitForSeconds (1);
9.   Debug.Log("Play Back Animation");
10.   //animation.CrossFade("Forward");
11.   yield WaitForSeconds (1);
12.   }
13. }

 

This seems to work but I get two errors:

Loading script assembly "Library/ScriptAssemblies/Assembly-CSharp-firstpass.dll" failed!
Loading script assembly "Library/ScriptAssemblies/Assembly-UnityScript-firstpass.dll" failed!

 

You most likely get them in MonoDevelop. Sorry, can't help with that, because I usually don't use UnityScript.

 

I also get
"The referenced script on this Behaviour is missing!"

 

Put the script on the object...

 

That means Unity "lost" the "connection" to a script and you need to reassign it!
CLICK ON THE WARNING MESSAGE. THIS WILL SELECT THE GAME OBJECT IN THE HIERARCHY WHERE THE SCRIPT NEEDS TO BE REASSIGNED.

 

I like how he's been ignoring my solution the entire time.

 

If that is your entire script it's never going to move anyway.
All you've told it to do is play those animations.
