📋 About This Mod
Add more variety to the range with slimes that combine two other slimes together!
Description:
Fusion Slimes Rework is a remake of my old mod Fusion Slimes but working far better. This mod adds slimes that are a mix between two slimes that can spawn all around the map. While largos are fully both slimes, Fusion Slimes are more like half and half. Not the most unique slimes ofc, but they add some fun variety to your game!! (Spawn rate may be a bit decreased with modded slimes).
Types of Fusion Slimes:
In the mod there are a few types of fusion slimes you can get.
-
[]Normal Fusion Slimes: These are your run of the mill Fusion Slimes, just a fusion between two different normal slimes (1 in 21 spawn chance in wild)[/]
[]Largo Fusion Slimes: Occasionally one of the slimes in a fusion will be a largo slime, there are not many places largos spawn in the wild, so it can be a bit rarer[/]
[]Clone Slimes: Clone slimes are a rare case where a fusion slimes spawns with two of the same slime (Especially since I have some code trying to prevent this. The probability varies from slime to slime and area to area, but is a 1 in 21 a^10 spawn chance where a is the spawn chance of the slime cloned)[/]
[]Fusion Fusion Slimes: Rarely, one of the slimes in a Fusion is a Fusion Slime, these fusions are a lot like fusions with Pink slimes (Again I have a decent bit of code preventing one of these from spawning in. It's spawn chance I believe is 2 in 21^21)[/]
[]Fusion Clone Slimes: While there is only one type of these, they are extraordinarily rare. It is also the only way to see the true nature of the basic unfused fusion slime (The rarity comes from both clone and fusion fusion prevention systems at once, making them essentially impossible to come across. Spawn chance should be about 1 in 21^221)[/]
Things I could work on:
I don't have any ideas atm
Mod Compatibility:
While fusion slimes will spawn with modded fusions, beware that modded slimes with more complex behaviors will be prone to error spam in the log. The slime should mostly work, and the game not break, but you will get annoying errors in the log. I don't know of many slimes that have issues atm besides some Ocean Range slimes (which that bug is really odd).
For mod Devs, I added the methods Fuser. AddModdedComponent() and Fuser. AddDiscludedComponent which should allow for you to tell fusion slimes info related to your behavior to prevent these issues.
Error codes:
While I would hope you wouldn't come across any of these. There are a few errors that can appear in chat when a fusion slime is spawning.
-
[](Warning) "Empty Constraints while fusing", this is a warning that should never appear. It indicates the spawner which the fusion slime spawned from has an empty constraints (constraints refer to rules for certain sets of slimes spawning) array. This array is important for getting slimes to fuse with[/]
[
]"Ssm is found empty", this error indicates something went wrong collecting members from the slime sets in the constraints (and the haul was empty). Again, this should hopefully never appear. [/][
]"Empty gofp, can't find fusion parents", this error indicates something went wrong getting the game objects from the members in the slime sets (again meaning the haul was empty). I am also pretty sure this error should never pop up.[/][
]"First parent for fusion in spawn was null", this is an error with a higher likelihood of appearing. It means that the gameobject picked from gofp was null, this may happen if null slimes are somehow in a slimeset. Albeit in the vanilla game there should be no cases of this[/][
]"Second parent for fusion in spawn was null", this is the same as the last one, but with the other slime in the fusion.
