PhysX raycast problem: Retrieving only one collision group

[shadowslair]

OK, here`s what makes me suffer for over a week...

The problem is that when I try to check the group of the returned by the raycast object, it always returns 1 (for GROUP_1_LEVEL - see below).
Somehow it`s not recognising the groups of the other Rigids. Their groups are assigned properly in their create events for sure.

First of all I create some PhysX collision groups, `cause I find it useful:

Code: Select all

enum COLLISION_GROUPS
{
	GROUP_0_NOCOLLISION,
	GROUP_1_LEVEL,
	GROUP_2_CHARACTER,
	GROUP_3_OBJECTS     //group for checking shootable objects 
};

I pass two vectors-origin and direction and defdist value for default distance to check.

Than I create my Raycast like this:

Code: Select all

{

	
      NxShape* shape = Scene->raycastClosestShape(
                  worldRay, 
                  NX_ALL_SHAPES, 
                  hit,
                  GROUP_2_CHARACTER, 
                  defdist);
}
// since the origin of the raycast is in the character`s collision volume
// I ignore it to avoid commiting a suicide =)

So, the question for a million bucks ( not literally ) is what am I doin` wrong?

I did my best to arrange the code, because by simply pasting here makes a mess, and tried to focus on the problematic function. The problem may be somewhere otside, so if you wanna know sth in particular, feel free to ask.

EDIT: I moved the topic from the Beginners section[/code]

Well one thing I would recommend is possibly using the shape that is returned by the raycast function instead of using NxRaycastHit. And if that doesn't work, then you could possibly try out raycast reports.

Thanks.

So, how it will look like? I don`t got it.

How will I return any value than?

( have to mention that chatting for three hours in the IRC drives me crazy )


Ahhh. Something like:

not hit. (...) but shape. (...) , is that right?

[Halifax]

Well it is actually described in this PhysX tutorial.

I got it working! Not exactly as I wanted, but will do it. Using shape->getGroup is working the same as hit.shape->getGroup, but you gave me an idea. I think I`ll suceed doin` it.

Thanks alot, Halifax!!!
