2 way collision meshes

[Wizrdwarts]

Why do so few game developers do this? Almost every game I've played, you could shoot out of a wall you glitched into, but not in. Is it impossible for the engine to stop bullets going out either way on just one collision mesh? 2 meshes would take up more performance. The only game I've seen that doesn't let you shoot out of walls is America's Army, and that runs on Unreal 2.5.

i always wondered that myself, that was a big issue in BF.

Yep, got to love it when people glitch in those buildings on Wake, or of course the hotel

Well to my understanding the object/mesh does not use 2sided faces, so only one side is visible and 'useable' if that makes sense, its pointless having inside or backfaces if nobody is going to see them, so you get a performance gain. But yea, I mean they could put 2 sided faces on buildings so if people glitch into them then the could not see anything outside (random or uncle sam texture i guess) but its just not worth it.

Nope! What they would have to do is this: Create more polygons on the inside of each building as a collision mesh, therefor pretty much doubling the amount of polys needing to be processed in each scene. Although, they could just make a cube with 8 verts and place one inside of each building making this a kill zone. Crysis has this ability.

Edit: what would be better though, is to just make it so we can go INSIDE all the buildings

Re: 2 way collision meshes

Could you not just have one collision mesh with two sides, so bullets would not go through either side instead of putting a shell or smaller mesh inside?

Is it the 1-sided thing that lets people get into the walls in the first place?

Re: 2 way collision meshes

Developers shouldn't need to have 2 way collision meshes because the players shouldn't be abusing these glitches.

Re: 2 way collision meshes

Part agree with AVR here but developers shouldn't need to have these things because the maps should be properly tested. OK its different for custom maps but then poorly made custom maps dont get played that often

Re: 2 way collision meshes

I don't know about other games but I remember glitching on CoD3 MP and you couldn't shoot out of the walls even though transparent, you could only shoot out of closed doors and windows.

Re: 2 way collision meshes

Another solution is to, when technology gets a bit more beefy, create buildings with full interiors instead of solid blocks. That way, the walls would be too thin for some douche to glitch in and mess around.
