How Would I make a chunk generator generate with less noise for the noise. I don't want it to generate mountains or anything like that.

I wonder what these do.

this.perlinHeight = new NoiseGeneratorPerlin(rand, 4);

(double)this.settings.stretchY

float f5 = this.settings.biomeDepthOffSet + biomegenbase1.getBaseHeight() * this.settings.biomeDepthWeight;

float f6 = this.settings.biomeScaleOffset + biomegenbase1.getHeightVariation() * this.settings.biomeScaleWeight;

      Immediately forceloading chunks? [1.18.2]

      By JayZX535 · Posted

      That's basically what the failure does, my apologies for failing to specify.  It just tries again on the next tick until it detects the entities for that chunk are loaded, and then tries to load the entity.  From there it gets into different failure states depending on what goes wrong, but in short, if the entity fails to load once the entity list becomes available, the request is cleared and must be resubmitted by the end user.  There should be few cases where that actually happens. Yes, that is my understanding of forceloading.  That's why on a successful summon, it removes the forceload.  Otherwise it does just leave the chunks loaded long term. Thank you for your help, any knowledge is useful!  I don't often mess with forceloading and my prior experience is 1.16 so I'm also a bit out of my depth haha.

      Immediately forceloading chunks? [1.18.2]

      By Xoroshio · Posted

      I will have to do more research about 1.18 chunk loading. You were unclear about how your code manages with the entity load failure. If you simply used a loop, I suggest submitting a tick task to the next tick which does the same thing, checking if the entities are loaded and if so teleporting the right one else submitting another tick task etc. Also I think forceloading permanently force loads the chunk, and it only starts to unload when you make a subsequent call to mark the chunk as not forceloaded. I may be completely wrong, I dont know much about 1.18, most of my experience is 1.20. Good luck I hope you figure it out after all this time 😅

      Crash during "loading mods"

      i managed to fix it by reinstalling the modpack and re-add all the extra mods I've had previously.
