Are all hitboxes in hl2 considered solid objectives for collision detection? Also is there a way to make a weapon only usable when it hits certain hitboxes and does nothing against other hitboxes? And finally, if I had two hitboxes, one inside the other, could I have some weapons ONLY hit the center hitbox while having others ONLY hit the outer hitbox?

These are just some modding questions I have, if I don't get a good answer I'll have to e-mail valve. ;(
 
There won't be any hit boxes. All the player models will be physically simulated and I think Gabe mentioned per pixel hit detection too.

All the damage location stuff in HL1 was hitbox based wasn't it? So this time around it should be more accurate.
 
actually, hl2 will use hitboxes, its doom 3 that uses the per pixel thing
 
OH!! Nvm, they are like damage zones-that per-pixel thing Id is doing. Yea, once, in Wolfenstein-I shot a guy in the space between his legs, he still bled. In Half-Life 2-your probably gonna be able to launch an object between people's legs and etc...
 
woulda been great if HL2 had perpixel hit, but I guess a good hit-box system would do.
 
But surely if everything is physically simulated, there is no need for hit boxes?

Hit boxes are the invisible box areas that cover parts of a model to tell the engine 1) where the character is hit and 2) where the character can be hit.
There was an uproar about the hit boxes for the heads of player models in CS being too big or too small.
 
Where does it say HL2 will use a hit box system?!!
 
I thought they were gonna use something similair to that pixel thingie, but with polygons, so the polygons of the model is the place where it can be hit.. I'm not sure of this thought, but it would be nice.

You know we have come a long way since Wolfenstein...
 
I'd like to see some proof saying whether they will or won't.

I don't get why, if an object is physically simulated in the world, like all bodies will be, there would be any need for hit boxes. It's simple, the object has a presence in the engine, why do you need to tell the engine where it is? It's there.

Obviously in HL1 and other games, there were no physical simulation so hit boxes were needed. Why would Source need hitboxes and where does it say there will or won't be?
 
Hey )[eVo]( Para, do you know a guy called )[eVoo]( Silly Hats? I met him in a Wolfenstein ET match.
 
there are no hit boxes in hl2, it's hit by the polygon. just scan through the "from valve only" thread on this site. they mention that bullets can fly between someone's legs and not hit anything.
 
Well, I just emailed Yahn, he's usually fast on replies so I'll see what he says.
 
I still think they are using hit boxes as I seem to remember them saying per pixel was a big drain on resources. Cant remember where this was from, i think a magazine preview.

I also remember them saying they had improved hitboxes since hl1 so you wont be able to tell the differene.

then again i could just be making this stuff up, so go email Gabe oO
 
Shoot - can someone find and post the directx triangle select demo? It uses a tiger model to show detecting tris in a model.... May help some people understand how it works.
 
If they are using hitboxes lets hope you don't have to aim BEHIND your enemy like you do in HL1.

-ios
 
Chris_D, the fact that some things are physically simulated doesn't matter. We know that HL2 bullets aren't physically simulated, they're just raycast like every other game. If they decided to keep the performance cost of hit detection cheap, then hit-boxes are required. If they decided to make it more accurate and therefore expensive, they could be using the model's rendered polys for hit detection.

EDIT: In addition, just because something's physically modeled doesn't necessarily mean its rendered polys are used for collision detection. For a complex object like a character, games typically use a bounding box to determine if the model collides with walls, floors, other characters, props, etc. The character is still 'physically modeled', but as a simplified object.
 
They have already stated that they will be using a hitbox system. It will have more boxes per model than the earlier hl, so you wont be shooting between a guys legs and causing dmg. But it wont be as exact as per polygon hit detection either.

IMO hit boxes is for the birds. But valve wants their game to run on low end comps so they have to make sacrafices where they can.
 
SheepFactory read your PM, now.
 
HL2 will probably not use hitboxes because it's outdated and not so realistic.

Example:

Player hides behind a wall.

Player 2 spots a part of Player's hand.

Player 2 opens fire at Player's hand.

Player does not take damage.


Well, I don't know if I'm making this up though. ;(

They will use hitboxes, not A hit box. Quake3 for example used A hit box, and the hit box was the same for every model. Hl2, from what ive read from the developers, will use multiple hit boxes to better comform to the model. So there will be a box to cover the upper arm, a box to cover the lower arm, a box to cover the hand, and so on. There shouldnt be any body part where you fire at but no dmg occurs.

How do you know? If you say if it was mentioned by a Valve official before, show me some evidence.

I dont save and catagorize every nuance of hl2 info i come across.

However, since im a nice guy, i will spend some time and look for the quote for you.
 
Half-Life 2 uses hit-box hit detection.

Subject: quick short question, promise!


Does HL2 use per-pixel hit detection? Or are we still working with hit boxes? Thanks!
 
Valve has stated a lot that Hl2 will be using hitboxes, not per pixel/polygon what have you. Valve stated that it was too much of a load on the system. Plus valve is updating the hitboxes. the head will have a perfect "box" to fit it so will the arms, legs feet whatever...

Trust me... Its not that big of a deal... Im sure valve will handle the hit detection quite well.:cheers:
