[FEATURE] VPhysics projectiles

[DESTROYGIRL]

Description

Make the detpack, frag & smoke grenades vphysics like half life 2 grenades

Proposed Solution

Make them vphysics so they can realistically roll around and interact with the environment, fit into small gaps and so on in a far more believable way, this would also eliminate issues involving them getting jammed in certain areas

Alternatives Considered

Don't because it would drastically change how people expect nades to (currently) behave

Additional Context

I'm a bit worried of how this might affect gameplay, since it would be very difficult to predict the rotational angle of your projectile when it hits a surface normal, so you couldn't quite tell which way it's gonna bounce. One approach could be applying the torque of the bounce to the angular velocity purely visually, but still use bounding box for the actual collision, so that we'd get the fancy visual of the projectile spinning around without sacrificing gameplay. Admittedly, I can't remember how exactly this is calculated currently but IIRC weren't not adjusting the angular velocity on bounce currently. Could be worth exploring.

IIRC the nades in HL2 were fairly easy to predict on the first bounce, but anything else after that was left to the elements to decide

Also another argument for reliable nade bounces would be smoke lineups, since these can often be several bounces. This is a pretty niche thing to do, but here's one such example: https://www.youtube.com/watch?v=OvcoBP0sDMY
