About this project
What does customspeed add?
This is a very simple mod to change the speed of certain cooldowns in the game:
1 The cooldown for villagers, animals and any other ageable to breed again.
2 The time necessary for babies to grow up.
3 Change the time for a mobspawner to spawn mobs.
4 Change the allay duplication time
The New 2.0 version in 1.18 and 1.19 uses gamerules to make the process easier, you can access them in the gamerule tab before the game launches and during a game with the /gamerule command.
You can have info by pressing the mod help key(k by default).
All the mods command start with : /gamerule customspeed.
The mod supports the following commands: (all the times are in seconds and the minimum time is 1 second).
gamerule.customspeed.adultVillagerbreed_150 : The cooldown for a villager to mate again.gamerule.customspeed.babyVillagergrowup_600 : The Time for a Baby Villager to grow up.gamerule.customspeed.adultAnimalbreed_150 : The cooldown for an Animal to mate again.gamerule.customspeed.babyAnimalgrowup_600 : The time for a Baby Animal to grow up.gamerule.customspeed.Spawnerspeed_20 : The average time for a spawner to spawn mobs again.gamerule.customspeed.allayduplciation_300 : The time for an allay to duplciate again
When creating a new world the gamerules can be found in the gamerules tab under the mobs category.

In the game, they can be found when typing /gamerule customspeed. ... (you need to have cheats activated to be able to use them)
For old er forge version 1.16.5 below
info: for the 1.2 1.16.5 version you can use the mod config tabe ingame.
However, as I can only use a slider, that max values are limited so you can use the commonspeed.toml in the config folder to increase it further.
The default time for the spawner has not been changed, but you can change it whatever you want (the game picks a random number between minspawndelay and maxspawndelay, I would recommend not going too crazy on it, it will make mob spawners spawn mobs really fast, but hey do whatever you want).
By default the time are reduces by half for breeding (from 5 to 2.5 minutes) and 8 minutes to grow up instead of 20.
Also the custom time for animal(animal_on) is disabled by default because it would also affect custom mobs. you can try ageable_on if the mod doesnt work on custom animals
with villager_breeding_on and breeding_on you can deactivate the breeding ( no babies will appear).
[for modded animals]: Basically if a mob makes babies and has a cooldown before making a new one it should work. will it work? normally yes but you never know what people do with their code, I would recommend testing it out by putting the values to 10 seconds and see if you can spawn babies and if they grow up immediately., and don't forget it will then affect every mob who makes babies.
from 1.14: the config is text only so you have to quit the game and change the values in the text file breedingspeed-common/customspeed-common.toml[ in the config folder]
if you don't know where it is go in the game main menu > mods> open mods folder> .minecraft> config and open the breedspeed-common.toml or **customspeed.toml(**for the latest version) with the notepad
1.16.5
!!! if you use the latest version customspeed 1.2 you can delete breedspeed-common.toml and customspeed-common.toml as it will no longer work and use customspeed.toml instead, this is only necessary if you want to increase the values over the max in game.
