transform.position not always getting called

Hi,

I was setting up a very simple platformer script that would set the player to go back to the start position after falling to a certain point.

I noticed however that "transform.position = startPos" is not always getting called when entering the if statement.

It seems random how many times it takes. Sometimes it is called on first time going through the if statement while other times it enters the if statement three times before the new transform position is set.

This is the if statement

Code (CSharp):

1. if (transform.position.y < -20f)
2. {
3.             Debug.Log("Player Died");
4.             transform.position = new Vector3(0f, 5f, 0f);
5.      
6. }

 

what is your problem?

 

the problem is that the line - transform.position = new Vector3(0f, 5f, 0f); is not always getting executed

Meaning that since the player is still below -20 on y it loops through again.

 

you have that on update?

 

Yes, have it under update. Tried it also as a public function and triggered by collison. The function runs but not the change in position. As a matter of fact I cannot get the transform position to change at all now.

Found out now that if I disable the Character Controller it works. So there must be something I have done wrong there.

 

Found solution in this thread:

You have to call Physics.SyncTransforms(); after the change on the transform.

Or enable in the project settings Physics->Auto Sync Transforms. But enabling this can impact performance.

This change in Unity sure had me pulling my hair out. Just glad I tested turning off the CC which then lead me to that thread.
