Combat

A hub for articles about creating fighting and combat in Source maps and mods.

Mapping

• ai_relationship - sets which NPCs will fight or ally with which others
• Standoffs - controls how NPCs behave during combat
• Assaults - organized attacks along a path
• Squads - getting NPCs to act as a team
• Rappelling (see external link)
• Door kicks (through the use of scripted sequences)
• ai_goal_police - station a guard at a door (non-lethal)
• path_corner - used to create patrol routes (see external links for tutorial)
• Turrets - fixed, movable, and usable varieties
• Hint nodes and Nodegraph for NPC navigation.

Entities

Most NPCs can fight, but some require special set-up:

• Dropships: npc_combinedropship; see external link
• Gunships and helicopters (npc_combinegunship and npc_helicopter) (see external link)
• Striders (npc_strider)
• headcrab cannisters
• npc_sniper

Notes

• NPCs will not move far, if at all, unless they have info_nodes. See Node graph.
• All types of Combine soldier are placed with npc_combine_s entities; see the model property.
• Human rebels are placed with npc_citizen entities.
