Tupenter
Resend chat and commands with a keybind and then even script them: chain with &&, inline math, variables, loops, conditionals, and your own commands with real autocomplete. All client-side, sending plain vanilla commands.
Become a walking repeating command block
The resend key allows you to quickly execute your last sent command 20x/sec!
Create custom commands and resend them easily with a keybind
/blink is one of my favorite custom commands I've made, it uses a raycast to teleport to a looked at surface. It also supports an optional maxDistance parameter
Simple command chaining
Set the time to day and clear weather. Both commands still have Mojang's autocomplete and syntax highlighting
Custom commands page
Uses mod menu to create a dedicated viewer and editor for custom commands
Complex custom commands with parameters
This custom command replaces a spherical area of non-air blocks. Only vanilla commands get sent to the server, so if your commands/sec setting isn't too high this will work on any server with op!
Script Editor Screen
Uses mod menu to create a dedicated viewer and editor for scripts, with a per-script toggle for individual worlds and globally
Running a complex script from a keybind
Tupenter supports complex scripts that resolve into pure-vanilla setblock commands. No command blocks or datapacks used!
Simple chat script to breathe fire
Every time enter is pressed it spawns a falling pillar of fire! Then hold the resend key to breathe continually without needing to re-open chat
