How to make ranged weapon use durability instead of just disappearing?

[pikafan8]

I tried to make a crossbow, which is weaker than the blowdart, but has a large number of finite uses. However, after firing the crossbow, it still disappears? Could I have some help with this?

 

local assets={    Asset("ANIM", "anim/crossbow.zip"),    Asset("ANIM", "anim/swap_crossbow_normal.zip"),	    Asset("ATLAS", "images/inventoryimages/crossbow.xml"),    Asset("IMAGE", "images/inventoryimages/crossbow.tex"),		}local prefabs = {    "impact",}local function onfinished(inst)    inst:Remove()endlocal function onequip(inst, owner)     owner.AnimState:OverrideSymbol("swap_object", "swap_crossbow_normal", "swap_crossbow_normal")    owner.AnimState:Show("ARM_carry")     owner.AnimState:Hide("ARM_normal") endlocal function onunequip(inst, owner)     owner.AnimState:ClearOverrideSymbol("swap_object")    owner.AnimState:Hide("ARM_carry")     owner.AnimState:Show("ARM_normal") endlocal function onhit(inst, attacker, target)    local impactfx = SpawnPrefab("impact")    if impactfx and attacker then        local follower = impactfx.entity:AddFollower()	follower:FollowSymbol(target.GUID, target.components.combat.hiteffectsymbol, 0, 0, 0 )        impactfx:FacePoint(attacker.Transform:GetWorldPosition())    endendlocal function onthrown(inst, data)    inst.AnimState:SetOrientation( ANIM_ORIENTATION.OnGround )endlocal function common()    local inst = CreateEntity()    local trans = inst.entity:AddTransform()    local anim = inst.entity:AddAnimState()    MakeInventoryPhysics(inst)        anim:SetBank("crossbow")    anim:SetBuild("crossbow")        inst:AddTag("blowdart")	inst:AddTag("sharp")        inst:AddComponent("weapon")    inst.components.weapon:SetDamage(0)    inst.components.weapon:SetRange(8, 10)        inst:AddComponent("projectile")    inst.components.projectile:SetSpeed(90)    inst.components.projectile:SetOnHitFn(onhit)    inst:ListenForEvent("onthrown", onthrown)    -------        inst:AddComponent("inspectable")        inst:AddComponent("inventoryitem")    inst.components.inventoryitem.imagename = "crossbow"    inst.components.inventoryitem.atlasname = "images/inventoryimages/crossbow.xml"		        inst:AddComponent("finiteuses")    inst.components.finiteuses:SetMaxUses(TUNING.WATHGRITHR_SPEAR_USES)    inst.components.finiteuses:SetUses(TUNING.WATHGRITHR_SPEAR_USES)        inst.components.finiteuses:SetOnFinished( onfinished )        inst:AddComponent("equippable")    inst.components.equippable:SetOnEquip(onequip)    inst.components.equippable:SetOnUnequip(onunequip)        return instendlocal function normalequip(inst, owner)     owner.AnimState:OverrideSymbol("swap_object", "swap_crossbow_normal", "swap_crossbow_normal")    owner.AnimState:Show("ARM_carry")     owner.AnimState:Hide("ARM_normal") endlocal function normalthrown(inst)    inst.AnimState:PlayAnimation("dart_normal")endlocal function normal()    local inst = common()    inst.AnimState:PlayAnimation("idle_normal")    inst.components.equippable:SetOnEquip(normalequip)    inst.components.weapon:SetDamage(75)    inst.components.projectile:SetOnThrownFn(normalthrown)        return instendreturn Prefab( "common/inventory/crossbow_normal", normal, assets, prefabs)

Wouldn't adding "projectile" component to the crossbow make it fire itself when you use it? Boomerangs and blowdarts are fine this way, but I think your crossbow is more similar to staffs or weather pain rather than them. So basically, the weapon and the projectile should be separated and you would need to make a new prefab file that defines the projectile.

 

Perhaps something like this...

On crossbow.lua (or whatever your prefab is named)

local prefabs = {    "impact",    "crossbow_normal_bolt",}

local function common()    local inst = CreateEntity()    local trans = inst.entity:AddTransform()    local anim = inst.entity:AddAnimState()    MakeInventoryPhysics(inst)         anim:SetBank("crossbow")    anim:SetBuild("crossbow")         inst:AddTag("blowdart")    inst:AddTag("sharp")         inst:AddComponent("weapon")    inst.components.weapon:SetDamage(0)    inst.components.weapon:SetRange(8, 10)    ------- ...

local function normal()    local inst = common()    inst.AnimState:PlayAnimation("idle_normal")    inst.components.equippable:SetOnEquip(normalequip)    inst.components.weapon:SetProjectile("crossbow_normal_bolt")        return instend

 

On crossbow_projectile.lua

local assets={	Asset("ANIM", "anim/crossbow_projectile.zip"),}local function OnHit(inst, owner, target)    inst:Remove()endlocal function common()	local inst = CreateEntity()	local trans = inst.entity:AddTransform()	local anim = inst.entity:AddAnimState()    MakeInventoryPhysics(inst)    RemovePhysicsColliders(inst)        anim:SetBank("projectile")        inst:AddTag("projectile")        inst:AddComponent("projectile")    inst.components.projectile:SetSpeed(50)    inst.components.projectile:SetOnHitFn(OnHit)    inst.components.projectile:SetOnMissFn(OnHit)    inst:AddComponent("weapon")    inst.components.weapon:SetDamage(0)    inst.components.weapon:SetRange(8, 10)    return instend 

 local function normal()      local inst = common()      inst.AnimState:PlayAnimation("normal_bolt", true)     inst.components.weapon:SetDamage(TUNING.NORMAL_BOLT_DAMAGE)      return inst end return Prefab( "common/inventory/crossbow_normal_bolt", normal, assets)
