problem with onCollision for each object [solved]

by Rami Bokhari · in Torque Game Builder · 05/24/2011 (7:26 am) · 8 replies

hey guys, what am I trying to do is to control the nCollision with specific objects..
I did :

function platform::onCollision( %srcObj, %dstObj, %srcRef, %dstRef, %time, %normal, %contactCount, %contacts )
{
   %classy = %srcObj.getClassName();
   if(%classy $= "bullet")
   {
   
   alxPlay(ShrekenWallHit);
   }

this code is not working! any help? I know it's a noob question am sorry XD

    Define onCollision callback within class you want it to apply to. That's what classes are for.

    function bullet::onCollision(%srcObject, %dstObject, %srcRef, %dstRef, %time, %normal, %contacts, %points) {
   alxPlay(ShrekenWallHit);
}

    thanks, but the problem is I don't want everything hit with the bullet play SFX I need to control it...

    Oh, I've got it wrong...

    Which part of it does not work? onCollision is not called, or %classy variable is empty, or alxPlay doesn't play anything? It shouldn't be hard to find where it does something you don't want it to.

    thanx man.. I did this and it worked

    function platform::onCollision(%srcObj, %dstObj, %srcRef, %dstRef, %time, %normal, %contactCount, %contacts)
{
   if(%dstObj.class $= "bullet" )
   {
   
   alxPlay(ShrekenWallHit);
   }
}

    it seems the problem was in getClassName()function

    thanx again Rpahut :)

    I think "isMemberOfClass()" function would work, I think. So you could say...

    function platform::onCollision(%srcObj, %dstObj, %srcRef, %dstRef, %time, %normal, %contactCount, %contacts)
{
   if(%dstObj.isMemberOfClass(bullet))
   {
   
   alxPlay(ShrekenWallHit);
   }
}

    And be mindful that %srcObj and %dstObj are not guaranteed to be in any given order. Either one could be the one that is hit or the one hitting, if you take my meaning....

    Also, wouldn't %this have to be added to the function-parameters for "platform"?

    If "platform" is an object then sure - however, depending on how the system is ordering collisions %srcObj might actually be %this anyway.

    You can set up scoped functions that don't rely on an underlying object - in which case the first parameter is not special in any way.
