help Spawn Set Piece with 100% chance

[zyxerdima]

Hello,

I'm working on mod and all almost done, but I stuck with problem - how to spawn Set Piece with 100% chance anywhere in the world? (e.g. like Pig King, but without special room)

My Set Piece "my_set_piece" static layout:

Spoiler

require("constants")
local StaticLayout = require("map/static_layout")
return {
            type = LAYOUT.STATIC,
            args = nil,
            defs = {},
            ground_types = {GROUND.CARPET, GROUND.CHECKER},
            ground = {
                    {1, 1, 1, 1, 1},
                    {1, 2, 2, 2, 2},
                    {1, 2, 1, 1, 1},
                    {1, 2, 2, 2, 1},
                    {1, 1, 1, 1, 1},
                    },
            --desctibe object which ones Set Piece should contain        
            layout = {
                    --pass Prefab name itself
                    pigtorch = {
                                     {x=-3, y=-3}, {x=3, y=3},
                                },
                    mermhead = {
                                     {x=-3, y=3}, {x=3, y=-3}
                                },
                    my_new_item = {
                                    {x=0, y=0}
                                },
                    },            
            scale = 0.5
}

As was mentioned at this comment it is possible to use ordered_story_setpieces at modworldgenmain.lua and it should do the job - generate Set Piece with 100% chance, so I've done

local Layouts = GLOBAL.require("map/layouts").Layouts
Layouts["my_set_piece"] = GLOBAL.require("map/layouts/my_set_piece")
Layouts["my_set_piece"].start_mask = GLOBAL.PLACE_MASK.IGNORE_IMPASSABLE_BARREN
Layouts["my_set_piece"].fill_mask = GLOBAL.PLACE_MASK.IGNORE_IMPASSABLE_BARREN
Layouts["my_set_piece"].layout_position = GLOBAL.LAYOUT_POSITION.CENTER

and added code with AddLevelPreInitAny ordered_story_setpieces

    AddLevelPreInitAny(function(level)
        if level.location ~= "forest" then -- only in overworld
            return
        end
        if level.ordered_story_setpieces == nil then -- if ordered_story_setpieces does not exist already, create it
            level.ordered_story_setpieces = {}
        end
        table.insert(level.ordered_story_setpieces, "my_set_piece")
    end)

But this didn't working for my Set Piece. Chances are around 50%.
At Teleportato mod source code I found usage of AddTaskSetPreInitAny so I've done

AddTaskSetPreInitAny(function(tasksetdata)
    if tasksetdata.location ~= "forest" then
        return
    end
    
	tasksetdata.set_pieces["my_set_piece"] = { count = 1, tasks={"Make a pick", "Dig that rock", "Great Plains", "Beeeees!", "Speak to the king", "Forest hunters", "For a nice walk", "The hunters", "Magic meadow", "Frogs and bugs","Oasis","Badlands","Lightning Bluff"}}
end)

And looks like it's working for 100% chances, but I don't know if it is good solution or no - have no idea what 'Task' is.

Looking forward to suggestions how it should be done.

Someone? Anyone?

A task basically means all the bits of worldgen (you can see it there in the examples like "speak to the king" is the pig king area), so attaching your set piece mod to a task is a legit way to do it. If you seem to have made it work 100% just give it some testing - regen a bunch of worlds, check your log files for errors etc.
