Question by Woutervd · Apr 28, 2012 at 07:42 PM · javascriptcollisiontransform.positionrespawn

Script error: respawn upon collission

Hello!

I am trying to write a script where the player (in this case just a sphere) respawns (as in, goes back to it's original position) when it falls off-world. I wrote the following script:

 #pragma strict
 var position : Vector3;
 function OnCollisionEnter(collision:Collision) 
 { if( collision.gameObject.tag == "Finish" ); 
 {transform.position : Vector3(0, 0, 0)}; 
 }

When trying to execute it, I get the following error: Assets/Die.js(5,1): BCE0034: Expressions in statements must only be executed for their side-effects.

What is going wrong?

Try with:

 #pragma strict
 var position : Vector3;
 function OnCollisionEnter(collision:Collision) 
 { 
    if( collision.gameObject.tag == "Finish" ) 
       transform.position = Vector3(0, 0, 0); 
 }

You have substituted an "=" with a ":", and this won't change the position. Also, you've ended the if statement with a ";". It should work now.

Thank you! I ended up using

 #pragma strict
 var position : Vector3;
 function OnCollisionEnter(collision:Collision) 
 { if( collision.gameObject.tag == "Finish" )
  {
  transform.position = Vector3(1,5,-2.8);
  rigidbody.velocity = Vector3(0,0,0);
  } 
 }

Which works great as a very basic respawn system. The biggest problem was indeed ending the if-statement with a semicolumn. This caused the script to not actually execute what was defined in the function.
