Being able to draw custom inventory images on minisigns

[JohnWatson]

AddPrefabPostInit("minisign",function(inst)
	if inst.qyt_customimagefix~=true and inst.components.drawable~=nil then
		local _OnDrawn_Old = inst.components.drawable.OnDrawn or (function() return end) 
		inst.components.drawable.OnDrawn = function(self,imagename,imagesource, ...)
			_OnDrawn_Old(self,imagename,imagesource, ...)
			if imagesource~=nil and imagesource.components.inventoryitem~=nil and imagesource.components.inventoryitem.atlasname~=nil then
				inst.AnimState:OverrideSymbol("SWAP_SIGN",GLOBAL.resolvefilepath(imagesource.components.inventoryitem.atlasname),(imagesource.components.inventoryitem.imagename or imagesource.prefab)..".tex")
			end
		end
	end
end)

place in modmain.lua

The script above lets you draw custom inventory images on minisigns. By default, the minisigns will just appear empty because the drawable component doesn't check if the item has a custom atlas.

Do you replace the ... with the item name?

[JohnWatson]

no, you just put this in modmain.lua

Really useful, thanks!

Are you sure there's nothing else that needs to be defined?
Testing it out, my custom item is still blank.

I would still like for this to be utilized. Custom items are still appearing blank on the minisigns.

make sure that the 'inventoryitem' component of your item has an 'atlasname' variable whose value is the path of an xml file

If you're referring to "inst.components.inventoryitem.atlasname", my items have that in their scripts.
