player_ragdoll

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.

player_ragdoll is a point entity available in Black Mesa. This entity used in multiplayer mode, tracks the position of dead player's corpse and moves the camera towards it. If the corpse is exploded in pieces, or if this entity is killed, the camera will show dropped canister instead.
