[Solved] Insert custom gensteps?

[Orion]

I would like to spawn some extra structures when the map is created. I've created a genstep for it, but now I've realized all existing gensteps are hardcoded.

Does anyone know if there is another way to get it to run?

I hit the same wall trying to create my Aethervent, and I think its something that might be in the changelog for alpha 9.

I was going to look at writing something that has a TickRare() that tries to determine when the map is first loaded, and then does the generation (and then sets a flag so it never triggers again).

Maybe something that looks for the colonist count to transition from 0 to 3+, and then generates the stuff in the same way (ie I don't think there is any problem with that in the same way other stuff is generated on the fly).

I did find a possible solution that I'm exploring now (kudos to alphalol's "AlphaTweaks").

Inheriting MapComponent creates a sort of global object after loading the map. Now I'm trying to figure out how to use Scribe_Values to check if it has run before. If it's the first time, I should be able to run my GenStep.

Once alpha 9 is there, it should be simple to run the GenStep in the originally intended way.

If anyone has more experience, getting this done, please let me know. If I figure it out myself, I'll post the solution here.

I found a way to check it:

Code Select Expand

using System.Text;
using RimWorld;
using Verse;

namespace SpawnTest
{
    public class MapComponent_SpawnTest : MapComponent
    {
        private bool created;

        public override void MapComponentTick()
        {
            base.MapComponentTick();
            if (!created)
            {
                Create();
            }
        }

        /// <summary>
        /// Create our stuff.
        /// </summary>
        private void Create()
        {
            Log.Warning("Creating fancy things...");

// Spawn code:

            //new Genstep_ScatterThings
            //{
            //    thingDefs = new List<ThingDef>
            //    {
            //        ThingDef.Named("NutrientPasteDispenser")
            //    },
            //    minSpacing = 5f,
            //    extraNoBuildEdgeDist = 4,
            //    countPer10kCellsRange = new FloatRange(0.7f, 1f),
            //    clearSpaceSize = 10,
            //    neededSurfaceType = TerrainAffordance.Light
            //}.Generate();

            // Will be saved when ExposeData is called later.
            created = true;
        }

        /// <summary>
        /// Upon loading or saving...
        /// </summary>
        public override void ExposeData()
        {
            base.ExposeData();

            Scribe_Values.LookValue(ref created, "Created");

            if (!created)
            {
                Log.Warning("Not created. This should not happen.");
            }
            else
            {
                //Log.Warning("Ready.");
            }
        }
    }

This seems to work fairly well, although things are spawned just after the game has started (a bit too late for my taste).

Nice, thanks, should be ok for me I think at the moment. Is there some XML definition that references the MapComponent_SpawnTest class?

Curiously not. It just automagically works. Although only for new maps (sorta makes sense).
