Hi

I am porting all my stuff to A8 and A8 PhysX (instead of ODE). Its not that easy as mentioned in the update notes i think. The documentation of the PhysX system in the manual seems to be a bit rudimentary too. Nevertheless most works fine now.

Whats still a miracle to me, is the trigger system. When activated, objects fall through the floor. Unless they are set to PH_STATIC. Did someone encounter similar problems?

What do you mean with "trigger system activated" ?

I had a similar problem and I solved it by adding to the entity that function pXent_setccdskeleton, but I had reduced the scale vector to: (0.25,0.25,0.25)

I also wonder what kind of system you meant?

Thanks. Ok, i mean the PhysX event function like this:

Code:

void weapon_pickup_physics()
{
	if(you!=player) return;
	my.event=NULL;
	if(!weapon_give_player())
	{
		wait(-1);
		my.event=weapon_pickup_physics;
		return;
	}
	pXent_settype(me, 0, PH_BOX);
	wait(1);
	ent_remove(me);
}

//uses _type, _mags, _silent
action weapon_physics()
{
        ...
	
	pXent_settype(me, PH_STATIC, PH_BOX);
	pXent_settriggerflag(me, NX_TRIGGER_ON_ENTER, 1);
	my.emask=ENABLE_TRIGGER;
	my.trigger_range=80;
	my.event=weapon_pickup_physics;
}

Hi there. Thanks, but its not solved yet. I still have the same problem. Here is the code:

Code:

void main()
{
	physX_open();
	pX_setgravity(vector(0, 0, -9.81));
	pX_setccd(1);
	level_load("...");
}

action physics_object()
{
	pXent_settype(me, PH_RIGID, PH_BOX);
	pXent_setccdskeleton(me, vector(0.2, 0.2, 0.2), 1);
	pXent_settriggerflag(me, NX_TRIGGER_ON_ENTER, 1);
}

I am certanly making a simple mistake... Does someone have any suggestions? (Thanks)

I suppose this may help...
I and others have had the problem of falling through the floor/terrain when we
up-graded to the A8 PhysX system... There is a major issue with the new system
where everything falls through terrains if your scale of your terrain is altered in wed.
In other words you might need to scale your terrain in med so that when you
locate it in wed it has a scale of one... This has caught a lot of us off guard...
Its just a shot in the dark... but... I hope that helps and solves the issue...

Thanks. But i am not using terrain, i have a block level compiled with the option "Build Simple Map".

You could use pXent_setcollisionflag, that works.
Otherwise you can file a bug report, of course.

Try to use that code, after your level map is loaded, maybe it helps.

Code:

...
physX_open();
pX_setccd ( 1 );
level_load("mylevel.wmb");
pXent_settype(level_ent,PH_STATIC,PH_POLY|PH_MODIFIED);
...

Thanks. I inserted the line after level_load, but it changed nothing.
