Forcing object collision from script

by Jack Stone · in Torque Game Engine Advanced · 08/09/2006 (10:05 am) · 2 replies

I'm trying to implement energy shields for my game, and I need to cause a projectile to "collide" using a script call.
I thought that calling oncollision would do it, but I started digging in the c++ and apparently thats called after the collision occurs.
From what I have found, I believe I need to call ShapeBase::queueCollision(ShapeBase* obj, const VectorF& vec) in order to force the projectile to collide. (in shapebase.cpp)

The only problem is, I can't access that function from script. Is there a way to access that function from script? (Is this where a console method would be used?) or is there a better way of doing what I want to do?
I considered creating a transparent dts object with a collision mesh in front of the projectile at the point that I want the projectile to collide, but that seems really messy, and not very efficient.
Also, if I can get queuecollision to work, what would I pass as the vector parameter?

Thanks for any help,
JS

I think I have it figured out now. I wrote a console method that looks like this:

ConsoleMethod( ShapeBase, queueShieldCollision, void , 2 , 4, "(ShapeBase* obj, const VectorF& vec) ")
{


ShapeBase * obj;

VectorF vec(0,0,0);

dSscanf(argv[3],"%g %g %g",&vec.x,&vec.y,&vec.z);


if (Sim::findObject(argv[2],obj)) {

object->queueCollision(obj , vec );

}




}

and I can force any object to collide with any other object from script. It looks pretty cool.

Basically, your just exposing queueCollision to the console. Nice and clean. I'm going to bookmark this, just in case I need it.
