How to delete Static Sprites

Hello,

I'm still messing with the Mini Platformer and what i want to be able to do is to place items around that $pGuy can pick up, ie like the Fish Food in that demo.

However i don't want to respawn the Item as they're placed on the level in the designer i would prefer the deleted after they've added the bonus to the player.

How do i do this? I'm used to in other languages etc just deleting/releasing the object but i can't see to find a way to do this.

This is the basic code for the collision of the itemclass and the %this.delete causes an error with the script.

function items::onCollision(%srcObj, %dstObj, %srcRef, %dstRef, %time, %normal, %contactCount, %contacts)
{
if(%dstObj.class $= "playerClass")
{
echo("Let's despawn this");
%this.delete;
}
}


So can anyone point me in the right direction please.

Thanks
