I created a trigger that follows a character.
I was wondering what is the best way to do this?
I created it by using sweep() function and physHit
I tried using cuts(). but I did not understand how to get the other colliding object. Any help out there?

What are you trying to achieve?
Do you want to check what physical actors are located withing a specified shape?
You can call Physics.cuts, provide a callback in which you can check each reported hit separately.
I think there are somewhere tutorials on physics callbacks (bloody massacre perhaps).

hmm.. bloody massacre was for licensed only?
i guess i can check that later on..
Yeah I'm looking for a moving trigger system.

Currently i have something like this:

Code:

void EnemyManager::Trigger()

{

ball.set(1.5f,2.0f,1.5f,Vec(pos()+matrix().y*0.8f));

PhysHit phys_hit;

if (bool collision=Physics.sweep(ball,Vec(pos()+matrix().y),&phys_hit))

    {

    if (state==WALKING)OpenDoors(phys_hit); // Checks if there are any doors in hes path. check if they should be opened.

    if (enemyScript!=NULL)enemyScript->CheckObjects(phys_hit); // Checks if there are any other objects //behaviors for them are in the script

    }

}

this is not working very well.. i would like to try achieving something similar with cuts?
