Smooth transition to radiated biome

Alphado-Jaki · March 26, 2018

I've come up with this idea while updating my terrain mod and guide. Personally, I won't use this for my mod, but looks useful for other modder, so I post here.

To whom haven't use RWG Previewer, Red is Radiated biome, Yellow is Wasteland biome.

This tweak removes radiated & wasteland from center of the world. Those biome are appears as player goes to far from center.

You can use this mod by 3 steps in rwgmixer.xml.

1. edit cell_cache_size into 9.

<?xml version="1.0" encoding="utf-8"?>
<rwgmixer>
<world ruleset="vanilla" />

<rulesets>
	<ruleset name="vanilla" cell_cache_size="[color="#0000CD"]9[/color]" cell_size="1800" cell_offset="0" generation_distance="10000" terrain_generator="vanilla" biome_generator="vanilla">

2. Edit biome_generators as below, or define new biome_generator.

	<biome_generators>

3. Edit biome_spawn_rules as below.

	<biome_spawn_rules>

	<biome_spawn_rule name="forest">

</biome_spawn_rules>

That's all!

Interesting idea. Seedname influence not destroying it?

You figured out what affects the parameter "cell_cache_size="?

Interesting idea. Seedname influence not destroying it?

Yeah, of course.

You figured out what affects the parameter "cell_cache_size="?

Several alpha ago, I tested lower than 8 (vanilla) because of curiousity. This resulted as some biomes are replaced with the unseen blank biome which generates only dirt and clay. So, I assume this option as how many biome can be generated per cell.

This is the SS of the blank biome. Highway road also vanishes.

Tested with some seedname. Looks nice to me.

!!!hmmm....Thanks for the info! now I can investigate it!

cell cache size is how many cells can be held in memory

Alphado-Jaki · March 27, 2018

cell cache size is how many cells can be held in memory

Thanks for correction

Does it mean this property won't affect generation itself?

n2n1 · March 27, 2018

cell cache size is how many cells can be held in memory

Yes... this is understandable, because it is written in the name of the function.

But what does that mean? it's about memory when creating the world? or when you draw during the game or like that ?

what does it practically affect?

how can we use this?

Alphado-Jaki · March 27, 2018

Yeah... I also want to know about that. Other options such as level can be find "how works" or "what is valid use", while some of them are broken for now.

But this, cell_cache_size, which appears at the first several line, is really unclear. What most modders (including me) can do is only guessing from behavior during trial and error (this causes misunderstand), or from meaning of the attribute name.

I hope devs make it clear sooner or later.
