World Loading Tweaker

World Loading Tweaker allows you to change the amount of spawn chunks used to load Minecraft terrain (worlds, dimensions, respawning, etc.) to increase the loading or quality of worlds!
Choosing a low amount of spawn chunks can drastically reduce the amount of time it takes to load a world, whilst choosing a higher amount can make it slow down, but improve the quality of spawning, like not having to see the chunks flash when they are loading.
When tested with spawn chunks set to 0, the world instantly skipped the loading box, and went straight to loading terrain, taking about 0.8 seconds to load.

When tested with spawn chunks set to 10, the world loading took about 3 seconds to load, but the amount of chunks loaded was better.

These results may vary depending on your computer, for example for some you may not notice any difference in loading times, but that is because this is made mainly for potato PCs, but loading times will still probably change even on high-end computers.
Minecraft's default spawn chunk radius is 2, just so you know.

Please note that to notice a difference in world loading, you must have played the world at least once with the pack installed, or it will not work.

I hope you enjoy!

Commands:
/function wlt:disable Disables the spawn chunks change and turns it back into 2 (you can still set it back whenever you want)

/function wlt:load
This doesn't do much, as it is already used when the world loads, but it sets the spawn chunk radius to 0

/function wlt:spawnchunkschange/0
Also sets the spawn chunk radius to 0

/function wlt:spawnchunkschange/1
Sets the spawn chunk radius to 1

/function wlt:spawnchunkschange/2
Sets the spawn chunk radius to 2

/function wlt:spawnchunkschange/5
Sets the spawn chunk radius to 5

/function wlt:spawnchunkschange/10
Sets the spawn chunk radius to 10
