CapabilitiesAdd()

Tested on Source SDK 2013 Singleplayer

CapabilitiesAdd allows the programmer to add capabilities to npc's

if your npc's Spawn function you can add capabilities like so:

void CNPC_YourNPC::Spawn(void){

	Precache(); // Runs your npc's Precache function

	SetModel(STRING(GetModelName())); // Sets the model
	SetHullType(HULL_HUMAN);// Sets body type
	SetHullSizeNormal(); // Sets body size

	SetSolid(SOLID_BBOX); // Set collision type
	AddSolidFlags(FSOLID_NOT_STANDABLE); 
	SetMoveType(MOVETYPE_STEP); // Sets move type
	SetBloodColor(BLOOD_COLOR_RED); // Sets blood colour

	m_flFieldOfView = 0.5; // Unknown, sorry :(
	m_NPCState = NPC_STATE_NONE; // Sets NPC state

	// Remove all capabilities so we can add our own
	CapabilitiesClear();

	// Add capabilities
	CapabilitiesAdd(bits_CAP_MOVE_GROUND);	// NPC can walk/run
	CapabilitiesAdd(bits_CAP_MOVE_JUMP);	// NPC can jump/leap
	CapabilitiesAdd(bits_CAP_MOVE_CLIMB);	// NPC can climb ladders
	CapabilitiesAdd(bits_CAP_MOVE_SHOOT);	// NPC can shoot weapon while moving
	CapabilitiesAdd(bits_CAP_USE);			// NPC can open doors/push buttons/pull levers
	CapabilitiesAdd(bits_CAP_OPEN_DOORS);	// NPC can open manual doors
	CapabilitiesAdd(bits_CAP_AUTO_DOORS);	// NPC can trigger auto doors
	CapabilitiesAdd(bits_CAP_TURN_HEAD);	// NPC can turn head, always bone controller 0
	CapabilitiesAdd(bits_CAP_USE_WEAPONS);	// NPC can use weapons (non-innate attacks)
	CapabilitiesAdd(bits_CAP_AIM_GUN);		// NPC can use arms to aim gun, not just body
	CapabilitiesAdd(bits_CAP_DUCK);			// NPC can cover and reload ducking
	CapabilitiesAdd(bits_CAP_WEAPON_MELEE_ATTACK1 || bits_CAP_WEAPON_MELEE_ATTACK2);	// NPC can do weapon melee attack 1 & 2
	CapabilitiesAdd(bits_CAP_INNATE_MELEE_ATTACK1 || bits_CAP_INNATE_MELEE_ATTACK2);	// NPC can innate melee attack 1 & 2
	CapabilitiesAdd(bits_CAP_WEAPON_RANGE_ATTACK1 || bits_CAP_WEAPON_RANGE_ATTACK2);	// NPC can do weapon range attack 1 & 2
	CapabilitiesAdd(bits_CAP_INNATE_RANGE_ATTACK1 || bits_CAP_INNATE_RANGE_ATTACK2);	// NPC can innate range attack 1 & 2

	SetMoveType(MOVETYPE_STEP); // gravity, special edge handling -- monsters use this
	NPCInit();

}
