How to create a custom rock

[iruizu]

I am trying to add an iron vein rock, but i just have no idea how to. I tried using the "rocks" prefab from the don't starve together files and i ended up with this code: 

Quote

local rock3_assets =
{
    Asset("ANIM", "anim/rock3.zip"),
    Asset("MINIMAP_IMAGE", "rock3"),
}

local prefabs =
{
    "rocks",
    "flint",
    "ironnugget",
    "rock_break_fx",
    "collapse_small",
}

SetSharedLootTable( 'rock3',
{
    {'rocks',       1.00},
    {'rocks',       1.00},
    {'rocks',       0.50},
    {'ironnugget',  0.25},
    {'ironnugget',  0.50},
    {'ironnugget',  0.75},
    {'ironnugget',  1.00},
    {'flint',       0.50},
    {'flint',       0.25},
})

local function OnWork(inst, worker, workleft)
    if workleft <= 0 then
        local pt = inst:GetPosition()
        SpawnPrefab("rock_break_fx").Transform:SetPosition(pt:Get())
        inst.components.lootdropper:DropLoot(pt)

        if inst.showCloudFXwhenRemoved then
            local fx = SpawnPrefab("collapse_small")
            fx.Transform:SetPosition(inst.Transform:GetWorldPosition())
        end

        inst:Remove()
    else
        inst.AnimState:PlayAnimation(
            (workleft < TUNING.ROCKS_MINE / 3 and "low") or
            (workleft < TUNING.ROCKS_MINE * 2 / 3 and "med") or
            "full"
        )
    end
end

local function baserock_fn(bank, build, anim, icon, tag)
    local inst = CreateEntity()

    inst.entity:AddTransform()
    inst.entity:AddAnimState()
    inst.entity:AddSoundEmitter()
    inst.entity:AddMiniMapEntity()
    inst.entity:AddNetwork()

    MakeObstaclePhysics(inst, 1)

    if icon ~= nil then
        inst.MiniMapEntity:SetIcon(icon)
    end

    inst.AnimState:SetBank(bank)
    inst.AnimState:SetBuild(build)
    if type(anim) == "table" then
        for i, v in ipairs(anim) do
            if i == 1 then
                inst.AnimState:PlayAnimation(v)
            else
                inst.AnimState:PushAnimation(v, false)
            end
        end
    else
        inst.AnimState:PlayAnimation(anim)
    end

    MakeSnowCoveredPristine(inst)

    inst:AddTag("boulder")
    if tag ~= nil then
        inst:AddTag(tag)
    end

    inst.entity:SetPristine()

    if not TheWorld.ismastersim then
        return inst
    end

    inst:AddComponent("lootdropper") 

    inst:AddComponent("workable")
    inst.components.workable:SetWorkAction(ACTIONS.MINE)
    inst.components.workable:SetWorkLeft(TUNING.ROCKS_MINE)
    inst.components.workable:SetOnWorkCallback(OnWork)

    local color = 0.5 + math.random() * 0.5
    inst.AnimState:SetMultColour(color, color, color, 1)

    inst:AddComponent("inspectable")
    inst.components.inspectable.nameoverride = "ROCK"
    MakeSnowCovered(inst)

    MakeHauntableWork(inst)

    return inst
end

local function rock3_fn()
    local inst = baserock_fn("rock3", "rock3", "full", "rock3.png")

    if not TheWorld.ismastersim then
        return inst
    end

    inst.components.lootdropper:SetChanceLootTable('rock3')

    return inst
end

return Prefab("rock3", rock3_fn, rock3_assets, prefabs)

however, when spawned through console it is invisible.

I also need help on getting worlgen to generate these new rocks.

You've taken this code from the prexisting rock file, yes? That deals with multiple prefabs using the same resources (anims), so where you've got:

inst.AnimState:SetBank(bank)
    inst.AnimState:SetBuild(build)
    if type(anim) == "table" then
        for i, v in ipairs(anim) do
            if i == 1 then
                inst.AnimState:PlayAnimation(v)
            else
                inst.AnimState:PushAnimation(v, false)
            end
        end
    else
        inst.AnimState:PlayAnimation(anim)
    end

It's not directly calling on anything in the rock3.zip file I assume you've created.

Have a look at other files for single prefabs and see how their bank/build is set and apply those.

It's always really useful for modding if you upload a zip/rar file of your WIP mod so we can look directly at your assets/code!

i didn't think a zip file of my mod was necessary, because my mod its basically that script and the textures so far...(the modmain is bascially PrefabFiles = {  "rock3", } ).

anyways

I managed to get the animation working, i used the gold vein bank with my own sprites and its working perfectly, when spawned the rock shows up, im able to hit it with the pickaxe and it goes through the 3 stages before finally breaking and releasing loot.

The only thing left to do now is get the rock to be spawned among other rocks during worldgen, wich i have no idea on how to do.

Check out the modworldgenmain file in the Tungsten mod, that'll give you a working example of spawning a rock item in worldgen.

Thank you so much, you helped me solve both my problems and now i got it working thanks to you!
