DeveloperTools

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

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.
