weapon I'm trying to make a character's own spear, and I need help.

[Wuf]

Hello everyone who is reading, I need help from more experienced people. I have very little understanding of coding, but I have already made some small progress (alas, only with night vision). I just can’t build the code for a custom spear, it’s quite ordinary, the battle spear code could even work for me, but alas, I can’t find it anywhere (in fact, I had an idea that when hit, the spear would cast poison, but I don’t know how to do even that). If anyone can help, I will be very glad.

P.S. Here is the code that I somehow put together, the mod certainly didn’t crash when entering the game, but there were no weapon in my inventory or craft:

local assets=
{    
    Asset("ANIM", "anim/corrupt_spear.zip"),
    Asset("ANIM", "anim/swap_corrupt_spear.zip"),
    
    Asset("ATLAS", "images/inventoryimages/corrupt_spear.xml"),
    Asset("IMAGE", "images/inventoryimages/corrupt_spear.tex"),
    
}

local prefabs = 
{
}

local function OnEquip(inst, owner)
    owner.AnimState:OverrideSymbol("swap_object", "swap_corrupt_spear", "corrupt_spear")
    owner.AnimState:Show("ARM_carry")
    owner.AnimState:Hide("ARM_normal")
end
    
local function OnUnequip(inst, owner)
    owner.AnimState:Hide("ARM_carry")
    owner.AnimState:Show("ARM_normal")
end
    
local function fn(sim)
    
    local inst = CreateEntity()
    local trans = inst.entity:AddTransform()
    local anim = inst.entity:AddAnimState()
    local sound = inst.entity:AddSoundEmitter()
    inst.entity:AddNetwork()
    
    MakeInventoryPhysics(inst)
    inst.entity:AddMiniMapEntity()
    inst.MiniMapEntity:SetIcon( "corrupt_spear.tex" )
    
    anim:SetBank("corrupt_spear")
    anim:SetBuild("corrupt_spear")
    anim:PlayAnimation("idle")
    
    --Weapon Ascpect
    inst:AddTag("sharp")
    inst.entity:SetPristine()

        if not TheWorld.ismastersim then
            return inst
        end
    
    inst:AddComponent("weapon")
    inst.components.weapon:SetDamage(51)
    -----
    

    
    -------
    inst:AddComponent("inspectable")
    inst:AddComponent("inventoryitem")

    inst.components.inventoryitem.imagename = "corrupt_spear"
    inst.components.inventoryitem.atlasname = "images/inventoryimages/corrupt_spear.xml"
    
    inst.components.inventoryitem.cangoincontainer = false
    inst.components.inventoryitem.onputininventoryfn = function(inst, player) 
    if player.prefab ~= "corrupt" then 
        inst:DoTaskInTime(0.1, function()
        
        player.components.inventory:DropItem(inst)
        player.components.talker:Say("It seems to slip right out of my hands!")
    end)
    end
    end
    
    
    inst:AddComponent("equippable")
    inst.components.equippable:SetOnEquip( OnEquip )
    inst.components.equippable:SetOnUnequip( OnUnequip )
    
    return inst
end

return Prefab("common/inventory/corrupt_spear", fn, assets, prefabs)

Does the prefab itself exist in the game? just curious, I'm not expert at these kinda things either but I want to make sure whether the prefab is added to the game or not.

Yes, it seems like there is, but even when I try to spawn it, it-.. Well, it’s just not there, it’s not invisible, it’s not there.

sorry my english is not very good

Can you perhaps try uhh, turning these into:

inst.AnimState:SetBank("corrupt_spear")
inst.AnimState:SetBuild("corrupt_spear")
inst.AnimState:PlayAnimation("idle")

Because right now from what I see, you're using local anim = inst.entity:AddAnimState() which would mean that Lua would probably see it as
inst.entity:AddAnimState():SetBank("corrupt_spear") and to me that just feels odd.

Also, I think you can just use inst.entity:AddAnimState() instead of local anim = inst.entity:AddAnimState().

(6o 6) I'll try, thanks

Alas, it didn't work

Ah heck. Clearly I'm not cut out for most of these things. I guess we need to wait for real professional help, sorry I can't help more.

It's okay, it was at least an attempt. Thank you

I'm not exactly an expert, but have you tried putting this in your modmain.lua? 

PrefabFiles = {
	"common/inventory/corrupt_spear"
}

I also am pretty sure that you don't need to put a file path as the name of your prefab, you can just put the item name in return prefab() (maybe that's the problem, maybe you tried to spawn a prefab called "corrupt_spear" when the only item that was added to the game was "common/inventory/corrupt_spear"). I also dont think that you need to have a prefab table because i've made custom items without these two things.
if that does work, and your item spawns in the game then i think i also know how to make the poison mechanic, in the health component there is a function called StartRegen(amount, period, interruptcurrentregen) so the code would look something like this (i havent tested it but this should maybe work)

local function onhit(inst, owner, target)
	target.components.health:StartRegen(-1, 5) -- you should probably also check if the target exists and has a health component
end

--other stuff until you add the weapon component

inst.components.weapon:SetOnAttack(onhit)

-- the rest of the code
