You can modify the x/y/z of a Vector3 as follows.

var vectorOne : Vector3;
vectorOne.x += 100;

If you want it to happen when objects collide, you can use OnCollisionEnter or OnTriggerEnter, depending on the rest of your setup.

i think i have a problem!

if(collisionInfo.gameObject.tag == "player1") { velocity.x = velocity.x* 10000;

}

if(collisionInfo.gameObject.tag == "player2") { velocity.x = velocity.x* -10000;

}

but the velocity is still not changing! In the inspector it is still 0! do you have any idea why?

$$anonymous$$ultiplying 0 by 10000 will result in 0! $$anonymous$$aybe add a "Debug.Log()" line in there to be sure that your ifchecks are working?

you were right the if was not working but im not sure what im doing wrong...

function OnTriggerEnter(collisionInfo : Collider) { if(collisionInfo.gameObject.tag == "player1") { print("HELLO"); velocity.x = (velocity.x+1)* -100;

}

if(collisionInfo.gameObject.tag == "player2") { print("HELLO"); velocity.x = (velocity.x+1)* 100;

}

}

the hello is not showing! although im sure my script is right! do u have any idea?
