|
||
|
// Purpose: Implements the zombie, a horrific once-human headcrab victim.
|
||
|
//
|
||
|
// The zombie has two main states: Full and Torso.
|
||
|
//
|
||
|
// In Full state, the zombie is whole and walks upright as he did in Half-Life.
|
||
|
// He will try to claw the player and swat physics items at him.
|
||
|
//
|
||
|
// In Torso state, the zombie has been blasted or cut in half, and the Torso will
|
||
|
// drag itself along the ground with its arms. It will try to claw the player.
|
||
|
//
|
||
|
// In either state, a severely injured Zombie will release its headcrab, which
|
||
|
// will immediately go after the player. The Zombie will then die (ragdoll).
