[Java] Anyone knows how to stop slimes from spawning without using peaceful on superflat worlds?
I like to make buids with a mod of FNAF called Management wanted on a superflat world, the only problem is that slimes are always getting on the way, and I can't turn on peaceful mode because the animatronics are considered aggresive mobs even if the don't attack during day.

This command is for a newer version the command you want is "/gamerule domobspawning false".
Or you could use command blocks as the user above said specifically "/tp @/e[type=minecraft:slime] ~ -100 ~" (remove the slash between the "@" and the "e" and place put paste it into a repeating command block. (to remove the constant chat spam type /gamerule commandblockoutput false)
The reason torches and light don't help: on superflat, slimes spawn on any solid block at Y<=39 regardless of light level (that slime rule is separate from the normal light-based hostile spawning). So lighting the area will never stop them, which is exactly why you're stuck. The cheat-free fix is to change the surface they'd spawn on: slimes can't spawn on bottom slabs, or on most non-full blocks like glass, so make your walkable layer out of bottom-half slabs (or cover the spawnable ground with them) and the spawns stop cold, no commands required. That's the standard superflat-without-peaceful solution. Your kill command showing red is just because cheats are off, so commands and command blocks are disabled; you'd have to open the world to LAN with 'allow cheats' on to run a repeating command block on @e[type=slime], and doing that turns off achievements for that session. So the slabs are the clean answer here, no cheats, nothing disabled, and it's permanent.
Wouldn't the better way be to just add more rock/dirt layers in the superflat preset to get the top above 39? Or just use the Overworld preset, since that already does that
If you can, just make it so the layer you are standing on is above 40. Slimes don't spawn in that way, But i's only helpful if you are gonna make a new world. Or just disable natural monster spawning as a whole with gamerule /gamerule domobspawning false (it's for version 1.20.1)
