Custom Air Drag

@havik I doubt that Source engine takes other entities into account when calculating air drag. I'd assume it's either placebo or maybe a different addon doing that. This addon only changes variables that Source uses to calculate the drag. It doesn't change the equations in any other way.

When I'm following an car, why does the air draft affects me and him?

@z̕͢oin̵k
Unfortunately Garry's Mod API doesn't provide a way to get information about the default drag properties of an entity, at most you can read the current state or change it.
I could technically store the initial values when the tool is first used on the prop, before applying the properties, but not sure if it's worth it.
If you have access to E2 or Starfall, you could probably whip out something that fits your needs quite quickly.

is there a way to reset props to their normal drag values?

They don't have to escape the map to disappear though, props can vanish when they spin too fast. Ik buggy props aren't the point of this addon but I only made them for funny physics interactions. I would've fixed this or made something like this for myself but idk how to code lua currently.

They probably just gain so much velocity that they fly outside of the map boundaries and get deleted by the engine.
You could probably hack around this in a few ways, but it's definitely outside of the scope for this addon. Just don't let your props fly around loose with negative drag :P

Things with -5 drag go so fast they vanish sometimes. Is there any way to fix that?

I've been looking for this exact addon for days. Only because I wanted to give props -5 air friction lol

do not put air drag at -1.00 , big mistake

the heck Megumin? what are you doing jeezus.
