grenade_satchel

grenade_satchel is a point entity available in Black Mesa. The grenade entity that is used by weapon_satchel. It is a  C-4 (explosive) charges that can be detonated with the remote radio. It also uses VPhysics, so you can pick it up and throw it like any other physical object. Steam versions use console variables to configure this entity, the mod version provides exclusive inputs and outputs that are cut in Steam versions of the game. Other inputs and outputs are same as CBaseAnimating.

Represented by class CGrenade_Satchel.

Note:This is the only prop that a player can pick it up in multiplayer mode (sometimes causes in glitchy animations for weapons, there is also a lack of interpolation and/or prediction).

Bug:You can't spawn satchels via Hammer or ent_create grenade_satchel in Black Mesa (the mod version). The game will crash instantly.

Note:While you can do this in the Steam version of the game, using this entity is pointless, mainly because Steam versions doesn't provide any inputs or abilities to detonate them.

Workaround:Use a toggleable model (or prop_physics_multiplayer) with env_explosion.

Bug:Doesn't work properly with level transitions if it wasn't transferred to the next level:

1. Becomes solid to player (only in ).

2. Can't be remotely detonated.

sk_detenator_satchel_plr_dmg_radius	300	Float	Damage radius from satchel.
sk_detenator_frag_elasticity	0.45	Float	Satchel's elasticity or how hard does it bounce. Doesn't work. Probably QPhysics was planned instead of VPhysics for satchels in multiplayer mode.
