How to remove Vanilla Trees

[rjord2018]

I am replacing the vanilla trees in Rimworld with new trees and am looking at how not to have vanilla trees appear when my mod is active.

Is there a way of doing this?

I think the best way would be to add your own biome(s) with only your plants (and probably other things) allowed.

But if you prefer a rough solution, you can patch <wildPlants> sections of vanilla biomes:

Code Select Expand



<?xml version="1.0" encoding="utf-8" ?>
<Patch>

<Operation Class="PatchOperationReplace">
<xpath>/Defs/BiomeDef[defName = "TemperateForest"]/wildPlants</xpath>
<value>
<wildPlants>
<YourPlant1>0.5</YourPlant1>
<YourPlant2>0.4</YourPlant2>
<YourPlant3>0.8</YourPlant3>
</wildPlants>
</value>
</Operation>

<Operation Class="PatchOperationReplace">
<xpath>/Defs/BiomeDef[defName = "TropicalRainforest"]/wildPlants</xpath>
<value>
<wildPlants>
<YourPlant1>0.2</YourPlant1>
<YourPlant2>0.2</YourPlant2>
<YourPlant3>0.7</YourPlant3>
</wildPlants>
</value>
</Operation>

</Patch>


Though some other mods may add spawning tags in the plants defs rather than biomes, so you may have to get rid of them, too:

Code Select Expand


<Operation Class="PatchOperationRemove">
<xpath>/Defs/ThingDef[defName = "SomeModdedPlant1"]/allowedBiomes</xpath>
</Operation>
<Operation Class="PatchOperationRemove">
<xpath>/Defs/ThingDef[defName = "SomeModdedPlant1"]/spawnChance</xpath>
</Operation>

<Operation Class="PatchOperationRemove">
<xpath>/Defs/ThingDef[defName = "SomeModdedPlant2"]/allowedBiomes</xpath>
</Operation>
<Operation Class="PatchOperationRemove">
<xpath>/Defs/ThingDef[defName = "SomeModdedPlant2"]/spawnChance</xpath>
</Operation>

Thanks for the reply... I had been looking at creating my own biome for the mod but have not yet found a tutorial on how to do it yet.

Am currently looking at biome def files in the MarsX mod as that mod is what I am trying to achieve
