About this project

What does DeveloperTools add?

DevTools

Minimal Minecraft 1.12.2 client-side mod that I made mainy for my dev env to save some time typing commands, but it can be just as useful for any player or pack maker. Client-side only, not loaded on the server side.

All keybindings are short actions to send the equivalent vanilla command as a chat message, this is how the mod is able to be client-side only while still working on any server. The Create Test World button creates a new world with the same settings each time, perfect for testing things in a controlled environment.

Keybindings

Key Action
F6 Switch to Survival mode
F7 Switch to Creative mode
F8 Switch to Spectator mode
F9 Toggle day / night
F10 Fully heal (restores HP and hunger)
F12 Repeat last command sent in chat

All keybindings are rebindable in the vanilla Controls screen under the DevTools category.

Repeat Last Command (F12)

Any command you send in chat (starting with /) is remembered. Press F12 at any time to resend it. Useful for rapidly re-running /give, /summon, or any other command during testing.

Main Menu: Create Test World

A Create Test World button is added next to the Singleplayer button on the main menu. It instantly creates and launches a superflat creative world with:

  • Creative mode
  • Cheats enabled
  • doDaylightCycle=false
  • doWeatherCycle=false
  • doMobSpawning=false

Each click creates a new world. Existing test worlds are not overwritten.
