Help with triggers and kactorspawnable

[peterfhannon]

Hi Folks,

I have a really simple level where pawns can push a ball around. I want to detect if the ball is pushed outside of the central square area.
I spawn the ball (subclass of KActorSpawnable) at the start of the level using unrealscript, and have created trigger volumes in the editor, with trigger events in kismet to capture the touch events and play a sound.

I've been banging my head against a wall for some time now ... How do I set things up so that the ball actually fires the touch event that I set up in kismet?

Heres my ball, the KActorSpawnable subclass:

Class TTBall Extends KActorSpawnable
      Placeable;

Simulated Event Tick(Float DT)
{
  //Do Gravity
  GravityForce( DT );
}

Simulated Function GravityForce( Float DeltaTime )
{
  StaticMeshComponent.AddForce(vect(0,0,-9.8));
}

Simulated Function AddForce( Vector force )
{
  StaticMeshComponent.AddForce(force);
}

Simulated Function SetRBLinearVelocity( vector aVelocity )
{
  StaticMeshComponent.SetRBLinearVelocity(aVelocity);
}

DefaultProperties
{
  Begin Object Name=StaticMeshComponent0
        StaticMesh=StaticMesh'tiki-taka.bigball'
        bNotifyRigidBodyCollision=True
        HiddenGame=False
        ScriptRigidBodyCollisionThreshold=0.001
        LightingChannels=(Dynamic=true)
	AlwaysCheckCollision=TRUE
	BlockZeroExtent=true
	collideActors=true
	
  End Object

  bNoEncroachCheck=false
  Components.Add(StaticMeshComponent0)
  StaticMeshComponent=StaticMeshComponent0;
  CollisionComponent=StaticMeshComponent0;
  collisionType=COLLIDE_TouchAll;
  bWakeOnLevelStart=true;
  bBlockActors = true;
  
  Physics=PHYS_RigidBody
}

simulated event PostBeginPlay()
{
	Super.PostBeginPlay();

	StaticMeshComponent.WakeRigidBody();
}

Also, how would I change the shape of the trigger volume to a cuboid?

Many thanks in advance,

Peter

It seems every time I post my desperate plea for help on here I figure it out shortly afterwards .

For anyone else struggling with a kactor or kactorspawnable and collisions/ trigger activation, your problem could be, as mine was, that you have simple box collision and or simple line collision set in the static mesh of the kactor you are trying to collide against things/ touch triggers. These simple box collisions claim to look to a physics asset to handle collisions - and I don't have a physics asset set so I presume this is why it was failing to register any collisions / triggers.
I think I set these trying to get something to work some time ago and didn't realize it would cause me so much grief! Hope this saves someone else a lot of stress...
