Grenade frag

This entity is not in the FGD by default.
It should not be put directly in a map because it can only be configured through code in Steam versions of the game. In the mod version, you still use it for rare cases, but it's more easy to use an exploadable prop.

grenade_frag is a model entity available in Black Mesa. The grenade entity that used by weapon_frag and HECU soldiers. It is a frag grenade that explodes after a certain amount of time, it also uses VPhysics, so you can pick it up and throw it like any other physical object. In multiplayer, used QPhysics (similar to Half-Life and Counter-Strike 2), so you can't pick up it, but it has a predictable throw path. 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_Frag.

Bug:Level transition will break the detonation timer, causing this entity to never explode.

Bug:In multiplayer, if a player dies while cooking frag and before throwing it, it will create a frag that will never disappear, it will also collide with other players.

Bug:Particles disappear after save loading.

Bug:This entity will never explode if spawned via Hammer or ent_create grenade_frag (not in ).

Note:Particles from this entity are different in mod and Steam versions.

Example.

This is how it looks like in all Steam versions of the game. This is how it looks like in the mod version (the image uses increased brightness and contrast for clarity).
