Widget Event

[DevilXD]

I have a small question... I'm making a mod with magical sword, which has the "finiteuses" component, but it will be unbreakable... Normally, after finiteuses reaching 0, tool breaks... But my sword has this function:

local function Discharge(inst)        inst.IsCharged = false        inst:RemoveComponent("finiteuses")    inst.components.weapon:SetDamage(30)        --inst:PushEvent("imagechange")    end

Everything works great, but removing "finiteuses" doesn't update "itemtile" widget, and leaves big "0%" on the sword image... Moving it to another slot causes "0%" to disappear, so it's iamge updating problem...

 

I tried to solve this, by adding to "finiteuses" this function:

local function FiniteUsesComponentPostInit(inst)    function inst:OnRemoveFromEntity()        --local itemtile = resolvefilepath("scripts/widgets/itemtile")        local itemtile = require("widgets/itemtile")        itemtile:PushEvent("imagechange")    endendAddComponentPostInit("finiteuses", FiniteUsesComponentPostInit)

...but the game crashes... Can someone help me?

Weapon is removed in on onfinished finction in your prefab file.

You can just put discharged sword in the player invenotry after charges reach 0%

you could search in other files it may be possible to equip that discharged sword rigth away.

 local item = SpawnPrefab("discharged sword")
        player.components.inventory:GiveItem(item)

I replaced:

local function onfinished(inst)    inst:Remove()end

on:

local function Discharge(inst)    inst.IsCharged = false        inst:RemoveComponent("finiteuses")    inst.components.weapon:SetDamage(50)        --inst:PushEvent("imagechange")    end

...and only issue is that sword image in inventory bar, which has a big "0%" leaved by removed "finiteuses" component...

I just need a way to update image in the inventory... I tried to do this by pushing an "imagechange" event in "scripts/widgets/itemtile"...

Maybe I am doing it the wrong way... How can I do this?

post the whole thing here I will fix it

It should not be nessesary, beacause better is to add OnRemoveFromEntity() function to "finiteuses" component, that updates image after removing it, right ?

 

By the way, is there any possible way to access a widget file from prefab ?

I was thinking about making 2 prefab files:

-normal discharged sword (this one is eternnal so no finite uses component)

-charged sword with finiteuses component

 

and just changing the prefab on ligtning strike to charged sword

after all charges run out just give the player discharged sword again

 

will try to code that on something

[DevilXD]

Ahh, I see... So simply I should split it in 2 prefab files, one with discharged and one with normal state... That solves my future problem with making "Super charged" state - simply add third prefab file... Am I right?

Maybe there is a way of updating that image, but I can't find it, tried few times with different things and nothing worked, so making them 2 prefabs is the only idea I have atm, but it can cause some problems.

Maybe someone else will know how to update that image after component is gone.

[DevilXD]

There is a way to change image of the item in inventory, ex. chester eye bone (two images, with open and closed eye...) It's something like:

 

inst.components.inventoryitem:ChangeImageName("path/to/file")

 

You can see, i was trying to use it (look in Discharge), but it didn't work...

But it only changes/refreshes an image, not a "child" tile on that image, in my case - "0%"...
