Load Support
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Shows when the player has too less Java memory allocated, and plays a sound when the game has finished loading.
It is fully configurable in config/loadsupport.toml.
Config 🚀
The config in config/loadsupport.toml is pretty self explainatory:
loadFinishSound = "minecraft:ui.toast.challenge_complete"
minMemory = 4.0
errorTitle = "Error: Not enough Java memory!"
errorMinMemory = "Please allocate at least {minMemory} GB of Java memory to your Minecraft instance!"
errorCurrentMemory = "You have currently {currentMemory} GB allocated."
memoryInfoLink = "https://github.com/vaporvee/LoadSupport/wiki/How-to-allocate-more-memory-to-your-Minecraft-instance"
{minMemory} and {currentMemory} get replaced by their actual values.
