====== Lua AI Common Function Repository ======

<code>
-- AI function repository by king bore haha / george
-- Made for DS1, but knowledge is very compatible with other games.

-- OnIf. Allows mid-action logic
-- Example: "combo 1, OnIf" allows you to recheck the target's distance and angle and decide the combo followup attack afterwards.
function OnIf_######(ai, goal, codeNo) -- Change ###### to the number ID defined in goal_list.lua (example: for Gwyn, it would be 537000)
	-- GOAL_COMMON_If codeNo can be checked here for different behavior.
    if codeNo == 10 then -- 
		-- Action go here
    elseif codeNo == 20 then
		-- Action go here
    end
    return 
end
goal:AddSubGoal(GOAL_COMMON_If, 10, codeNo) -- codeNo checked in onIf function to allow different behavior

-- OnIf v2.0, devised by Meowmaritus
ENABLE_COMBO_ATK_CANCEL(GOAL_COMMON_If) -- Allows GOAL_COMMON_If to utilize Combo recovery events. (Personally, I put this in "if.lua".)
function OnIf_######(ai, goal, codeNo) -- Change ###### to the number ID defined in goal_list.lua (example: for Gwyn, it would be 537000)
	-- GOAL_COMMON_If codeNo can be checked here for different behavior.

		-- Action go here
    elseif codeNo == 3010 then
		-- Action go here

-- Target Types (TargetType)
-- Any instance of a targetType in list list can be replaced with any other type. (Example: replacing an attack's TARGET_ENE_0 with TARGET_FRI_0 will make them aim at an ally)
-- (In example commands, I used  in default target types that are USUALLY what you want)
TARGET_NONE
TARGET_SELF -- self
TARGET_ENE_0 -- enemy
TARGET_FRI_0 -- ally
TARGET_EVENT -- unused
TARGET_LOCALPLAYER -- the player (host)

-- GetDist
-- Check target's distance in comparison to self's origin position (in meters)
-- Distance is offset by self's npcParam hitRadius
-- If target is within hitRadius, distance will be negative. Distance will continue to decrease as target approaches origin
-- -- Lowest possible value is when target is at self origin, which would have a distance of negative hitRadius
-- If target is outside of hitRadius, distance will be positive. Distance will continue to increase as target leaves origin
