Ok, I am using a .b3d and a .md2 version of my monster and from a previous thread someone mentioned that md2 had better performance. They were 100% correct.

The problem I am having is the I cannot use [code]Collision Bullet,Badguy,2,1[\code] to register a hit.

It makes me use [code]Collision Bullet,Badguy,1,1[\code] instead.

Why is this? Is there a fix for it? I really need to use "method 2" on my MD2 models.

thx :)

You can't. The only solution I can think of is to collide with an invisible B3D proxy or similar. You may have problems syncing up animations tho.

Wait a minute.. you can't collide with the animated b3d mesh anyway. What exactly are you trying to do? You would have to collide with animated bounding boxes/spheres.

I have a radius of 1 for both model types. I am shooting at them, and the B3D using method 2 lets me shoot ANY part of the badguy and it registers a hit.

The Md2 will not register a hit unless I use the method 1 and it only registers if I hit the previously set radius.

So it appears as if the MD2 will only use the radius, and B3D will let me actually check if I hit the bad guy in the head or fingers. B3D offers a great deal more realism in a fire fight....but the performance is 1/2 of the MD2's.

So I was hoping for a MD2 solution that would let me shoot the badguy ANYWHERE I want...not just the radius.

You can only hit his fingers or arm at the un-animated mesh position. Check it.

You can use line pick

Ooh ooh ooh, can't you just place a bunch of pivots with collisions as hitboxes?

I decided to assign collisions to MD2's via

collisions type_player,type_badguy,3,1

where the Const have been already set.

Now, I am trying to get the grip on the

 EntityBox ,x,x,x,x,x,x

command.

Can someone explain how this works? Meaning, does the first 3 "x,x,x" need to be "0,0,0" or what ?

thx
