Issue with character-specific actions

[TigerPrascire]

I have completed my mod, however, the action my character can do is available to ALL characters when the mod is installed. How do I make it so only this one character can perform that action instead of anyone. Is there a code I can use to identify the character by name and say that only that character can then perform the listed action?

Either add a specific component for your character (like the Reader component for waxwell and wickerbottom), or check for your character in the action (if act.doer and act.doer.prefab == "yourcharacter").

Not sure where to add the act.doer check in the code. Should I add it in the components file for the throwable or should I add it in the modmain somewhere?

No, I meant if you were creating a whole new action for your character. Take a brief look at actions.lua to see what I meant. Or don't.

If you want your item to only be available to your character, make your life easier and just make it character-specific. Add this to your item definition:

inst:AddComponent("characterspecific")
inst.components.characterspecific:SetOwner("yourcharacter")

If you want your item to be available to all characters and to make it so only your character throw it, try using something like this in your modmain.lua:

local function Throw(self, pt, thrower)
	if (self.specialuseby ~= nil and thrower and thrower.prefab ~= self.specialuseby) then
		return false
	end
	self:OldThrow(pt, thrower)
end

local function ThrowablePostInit(self)
	self.OldThrow = self.Throw
	self.Throw = Throw
	
	function self:SpecialUseBy(prefab)
		self.specialuseby = prefab
	end
end

AddComponentPostInit("throwable", ThrowablePostInit)

and this in your item file:

inst:AddComponent("throwable")
inst.components.throwable:SpecialUseBy("yourcharacter")

Note: it might work, but I wouldn't count on it. It's untested and I'm not reliable to begin with. Hopefully the intent is clear and helps you find a solution. Feel free to ask if anything isn't obvious or if you have any issues.

I can't get it to work and I've been at this for hours. It seems like wherever I add an exception for one character to have this action, it breaks EVERYTHING. Here is my code, without the exceptions added in, so you can see what I'm dealing with and sorry for how much of a spaghetti mess this is.

Am I correct to understand that this code works (no crashes) and lets any character throw both regular spears and tiger's spears, and you want to change it to only allow your character to throw spears? If that's the case, try adding this right after SPEARTHROW.fn = function(act):

	if (act.invobject and (act.invobject.prefab == "spear" or act.invobject.prefab == "tigerspear"))
	and not (act.doer and act.doer.prefab == "yourcharacter") then
		return false
	end

It works! It's a little clunky but.. it works! The other characters still try to throw the spear, it says "I can't do that", then the spear appears in their hand again. But it never leaves their inventory. Amazing! Whenever I tried that, either every character couldn't do it or it'd just crash

I guess that's better than nothing.  Sorry, I can't think of any "cleaner" solution other than making the items exclusive to your character.
