Mob spawn minimun tile dimension

[BoroBeast]

Hey core keepers,

What is the minimum dimension of a tile set to spawn mobs like slimes ? Is it 16x16 and if it's smaller they dont spawn ?

What are the conditions to do a farm mob zone

One more QUESTION : Can you plant seeds like 5x5 at a time or for now you can only do 1 by one ?

As far as my knowledge there's no minimum, as long as the spawn floor exists it can spawn the enemies. Think there's more info on the wiki but unless something changed with 1.0 the system use to work like every spawn floor in a range of you would roll every X amount of time and if it hit right an enemy would spawn there. As such the more floor there is the higher the odds you hit on the spawn.

Second question again unless something changed with 1.0 (which I haven't seen) planting is still 1 spot at a time for some unholy reason. There was a mod called placement plus that solved that issue but the creator is having issues making it work on the 9.9.9 and 1.0 versions of the game due to some back end changes that happened.

Mob spawns happen in 16x16 chunks of tiles (call it a cell). When you view the map, you can see your coordinates, with (0,0) being the lower left corner of the first chunk, so moving to the right 16 tiles and up 16 tiles is the dimensions of your cell.

Each mob has a minimum amount of tiles needed to spawn a mob. For most slimes as an example, this is 6 slime tiles of the matching color. There is also an associated spawn chance percentage based on how many tiles are present beyond the minimum. I can't specifically remember how this check works, but for a 90% chance of spawn for the slimes, you need 7 slime tiles in your 16x16 cell.

Most mobs will only spawn ONCE per 16x16 cell, per type of mob (or maybe tile). So, if you have 8 slime tiles in your 16x16 cell to spawn an orange slime with a 100%+ chance, or if you have 256 slime tiles to spawn an orange slime, you will still only spawn ONE orange slime, because the check only happens once PER CELL. So you only need 8 total orange slime tiles in your 16x16 cell.

Each mob has a spawn check in a cell every 15-22 minutes, so they don't all happen all at once with all the other mobs. This means mob farms can be a little slow.

Here is a wonderful chart with specifics for each mob and their spawn requirements.

Did I hear that they changed how mobs spawn in the 1.0 update? Or are they still working basically the same?

I haven't seen much of a change in game with a running compact mob farm, but there could be slight changes that I haven't noticed?

Cool, thanks!
