Editing the Character Model Mid-Game

[FurryEskimo]

My Mod:  https://steamcommunity.com/sharedfiles/filedetails/?id=2238207705
Forward:  My character's 'feet' are actually part of the legs, so I made the foot textures blank.  This looks fine, unless someone tries wearing pants or shoes, since for one, there are no feet!

Solution:  Make the feet appear and disappear, and the legs change texture, based on what clothes are being worn.
Proof it can be done:  https://steamcommunity.com/sharedfiles/filedetails/?id=2268841188
This character's feet are invisible unless they have pants on, and no shoes.  The torso texture also updates when the character is wearing pants.

My work so far:  I re-added some feet textures to my character, and they display correctly when viewed on the character select screen and when trying on outfits at a dresser, but the feet texture is always visible when actually playing the game.  It seems like I need to tell the skin in-game to update to the new texture, but I'm not sure..  I also haven't tried changing the leg textures the way Jelliet the Slime's torso texture changes.  I suspect there's basic code in the game that handles all of this, but I haven't found it yet.

I've attached my mod's current modmain.lua file, where I've been implementing these changes, and Jelliet's, which has already implemented this type of code.

I would reccomened checking out the Skinner component for now sorry i can't really touch my computer cus homework and e.c

I think I found a reference to the kind of thing I'm trying to do.  There's a note reading "--Hack for wormwood cactus legs hiding feet. If someone else sets legs (full body piece) we want to show the feet again. This should be generalized better if we're going to do more silly stuff like feet hiding."

I'm still figuring out how this all works and how to update the appearance, but there's a note Jelliet's code too:

	-- At "0" Skinner is still initializing - we need to push our changes after that
	inst:DoTaskInTime(1, function(inst)
		if inst and inst.components.inventory and inst.components.inventory:GetEquippedItem(EQUIPSLOTS.BODY) then
			if (inst.components.inventory:GetEquippedItem(EQUIPSLOTS.BODY)).components.container then
				inst.AnimState:SetSymbolExchange("swap_body", "swap_body_tall")
			end
			inst.AnimState:Show("swap_body")
		else
			inst.AnimState:Hide("swap_body")
		end
	end)

I suspect there's more, but feel like I've only just started to understand how any of this code really works.

Edit:  Huh..  So in Jelliet her feet are referred to as 'nub's which I thought was just a code coding phrase unique to their mod, but I think it might be pre-programmed!

--deal with foot nubs
local has_nub = BASE_FEET_SIZE[base_skin] == -1
local nub_build = base_skin
if clothing_names["legs"] ~= nil and CLOTHING[clothing_names["legs"]] ~= nil and CLOTHING[clothing_names["legs"]].has_nub then
	has_nub = CLOTHING[clothing_names["legs"]].has_nub
	nub_build = clothing_names["legs"]
end
if has_nub and symbol_overridden["leg"] and not symbol_overridden["foot"] and leg_build ~= nub_build then
	anim_state:OverrideSkinSymbol("foot", nub_build, "nub" )
	feet_cuff_size = 0
end

I tried coding them in before, but nothing happened, but maybe that's because I don't yet know how to activate this code.

Edit 2:  I've tried making more edits to incorporate these changes, but the whole mod started to crash.  I decided to tear out all the cosmetic editing code and start from scratch, but for some reason this code has somehow made itself embedded, and refuses to come out without crashing the mod.  I performed a hard reset to about a week ago and it's working again.

inst:ListenForEvent("equipskinneditem", function_)
inst:ListenForEvent("unequipskinneditem", function_)
inst:ListenForEvent("onchangemoddedskin", function_)

maybe use these events to make sure the code sticks and in the onload function

Thanks.  I'm currently trying to use that to make these edits from inside the character's own prefab file.  So far every time I've tried, inst.clothing ~= nil has come up false, resulting in "No clothing was registered" and so no edits to the visuals.  Also this code only activates when clothing is confirmed, not tried on, which might be an issue down the line..  When I added the code to listen for unequiping clothes without actually adding the function, the server launched, but the world appeared to have been rerendered, but with no portal, and then it crashed, which is a very strange problem but one I experienced yesterday while trying to get this code working.

local function equipskinneditem(inst)
	print("Item has been equipped.")
	local overrideslegs = false
	if inst.clothing ~= nil then
		print("There is clothing.")
		if inst.clothing["legs"] ~= nil and inst.clothing["legs"] ~= "" then
			print("There are pants.")
			for k,v in pairs (CLOTHING[inst.clothing.legs].symbol_overrides) do
				if v == "leg" then
					print("Will override for legs.")
					overrideslegs = true
				end
			end
		end
		
		if overrideslegs and not overridesfeet and (inst.clothing["feet"] == nil or inst.clothing["feet"] == "") then
			print("There are pants and no shoes, so making texture swap!")
			inst.AnimState:OverrideSymbol("foot", "furryeskimo", "nub")
		end
	else
		print("No clothing was registered, somehow?")
	end
end

local function unequipskinneditem(inst)
	print("Item has been removed.")
	--Do nothing, for now.
end

Made a breakthrough!  It's not done, there's plenty more to do, but it seems to work!

local function equipskinneditem(inst)  --Test code.
	print("Item has been equipped.")
	local overrideslegs = false
	local overridesfeet = false
	if inst.components.skinner.clothing ~= nil then
		print("There is clothing.")
		if inst.components.skinner.clothing["legs"] ~= nil and inst.components.skinner.clothing["legs"] ~= "" then
			print("There are pants.")
			for k,v in pairs (CLOTHING[inst.components.skinner.clothing.legs].symbol_overrides) do
				if v == "leg" then
					print("Will override for legs.")
					overrideslegs = true
				end
			end
		end
		
		if overrideslegs and not overridesfeet and (inst.components.skinner.clothing["feet"] == nil or inst.components.skinner.clothing["feet"] == "") then
			print("There are pants and no shoes, so making texture swap!")
			inst.AnimState:OverrideSymbol("foot", "furryeskimo", "nub")
		end
	else
		print("No clothing was registered, somehow?")
	end
end

Edit:  And I spoke too soon..  For some reason it's registering me as wearing clothes 100% of the time, even when I have nothing on..

Ok, by editing the skinner PostInIt, which relates to clothes, I got the visual appearance of the feet working correctly while playing, but not while trying on clothes, which I'd managed to do before!  I made the skinner edit in modmain.lua and it seems to activate when the game starts, and every time I select an outfit, but not when just trying them on in the display menus.

local CLOTHING = GLOBAL.CLOTHING  --Test code.
local function SkinnerPostInit( skinner )
	print("Skinner code activated!")
	local _oldSetSkinMode = skinner.SetSkinMode
    skinner.SetSkinMode = function( self, skintype, default_build)
	
		if self.inst.prefab ~= nil and self.inst.prefab == "furryeskimo" then
			self.inst.AnimState:ClearOverrideSymbol("foot")
			self.inst.AnimState:ClearOverrideSymbol("torso")
		end
	
		_oldSetSkinMode(self, skintype, default_build)
		
		if self.inst.prefab ~= nil and self.inst.prefab == "furryeskimo" then --skintype ~= nil and skintype ~= "ghost_skin" and

				local overrideslegs = false
				local overridesfeet = false
				
				local overridestorso = false
				local overridespelvis = false

I'll probably need to make further edits to this, but it's working, for now.

[FurryEskimo]

I got it working, finally.  I have the worst headache and am going to get some rest before revisiting this.  It still has trouble with pants that include feet, or costumes that include feet.  When that happens it simply makes them invisible.

christ dude, i went to bed and you fixed this wierd ass problem, props

[FurryEskimo]

@thomas4846

haha, thanks.  I’m just glad to have figured it out.  My game was hard-crashing almost non-stop while testing this, but I got it.  Putting it in the character’s file helped a lot, because the print functions started working and I could hone in on what was/wasn’t working.

Also, I think what I need to do now is add a third option to the code for when it’s overwriting the feet.  When the base legs/feet are showing, the ‘feet-feet’ texture needs to be invisible, including shoes.  When legs are added and not shoes it adds the custom feet texture, but when legs and feet are added it should do literally nothing, so they will appear normally.

Edit:  Yep, I was right!  Slipped in just a liiiittle extra code and it appears to work just fine now!

elseif overrideslegs and (overridesfeet or clothing_names["feet"] ~= nil) then
	print("Overriding nothing, default feet!")
	--Do nothing.

Edit 2:  Turns out that code works for the first half, that determines how the character looks when selecting clothing.  The extra code needed in the section that actually applies that code to the character looks like this:

elseif overrideslegs and (overridesfeet or self.clothing["feet"] ~= nil or self.clothing["feet"] ~= "") then
	print("Overriding nothing, default feet!")
	--Do nothing.
