What's this part of the code supposed to catch?

Here? probably nothing, i got some of my code from one of my scripts that had vectors in them, so it was probably left-over from something, in case the object bottom was pointing at the sky resets it

I'm not optimistic about uncertain code - either give it a comment or remove it. surfaceNormal returns the normal to the terrain at that location, so it seems out of place.

Yeah, no, i will remove it, it was originally a code that would create an Ace circle tag where the explosive was, and when it was in a ramp in a certain modded object it returned 0,0,0 and would place a floating/clipping circle in the ramp, so that was a bandaid fix.

on the second hand, iirc if there isn't a FireGeo LOD it defaults to normal Geo right? i should probably replace "FireGeometry" here for for "Geometry" do you agree?


private _bbox = boundingBoxReal [_expSetupVehicle, "FireGeometry"];
_offset = -((_bbox select 0) select 2);
