monster_alien_slave (aka Vortigaunt) #

TWHL

Changes #

Restores some bits of its health upon damaging targets with electro-attack (if vortigaunt_selfheal feature is enabled).
When full on health vortigaunt gains an additional energy upon electrocuting enemies. The energy is used to execute new abilities.
Can revive fallen ally alien slaves using an excess energy (if vortigaunt_revive feature is enabled). Unlike Sven Co-op implementation it does not halve the maximum vortigaunt health. Instead vortigaunt can be revived only once.
Can heal injured ally alien slaves spending an excess energy (if vortigaunt_heal feature is enabled).
New ability: a coil attack (if vortigaunt_coil_attack feature is enabled).
Vortigaunt’s arms are glowing upon charging an electro attack.
When a vortigaunt has an excess energy, his claws deal more damage (claws are glowing at the time of melee attack) (if vortigaunt_arm_boost feature is enabled).
When idle, plays some additional effects like random lightning (a feature cut from Half-Life) (if vortigaunt_idle_effects feature is enabled).
If player is ally, vortigaunt can charge player’s suit armor (requires energy) kinda like in Half-Life 2 (if vortigaunt_armor_charge feature is enabled).

Skill variables #

sk_islave_health - monster’s health.
sk_islave_dmg_claw - melee damage.
sk_islave_dmg_clawrake - melee damage (event 2) (not used?).
sk_islave_dmg_zap - zap beam damage. Note: alien slave creates two zap beams, so he can deal double damage if both beams hit the target. This also controls how much alien slave heals another. The maximum coil attack damage is this variable multiplied by 2.5.
sk_islave_zap_rate - framerate of zap attack animation. In Half-Life it wasn’t configurable. Default values: 1 on easy and medium, 1.5 on hard (replicating the behavior from Half-Life).
sk_islave_revival - whether alien slaves can revive each other. 0 means revival is not allowed. 1 means revival is allowed. Default values: 0 on easy and medium, 1 on hard.

Azure Sheep Pantheyeye

The Panthereye in Azure Sheep is based on vortigaunt, so we can implement it via entity template. Do not confuse it with monster_panthereye. The only thing that is currently missing is replacement of skill values (for higher damage output). We also took liberty of increasing the monster’s bounding box size to allow projectiles properly hit the panther.
