Simple Move

by SuperAntx
Add strafing or diagonal movement to your game in just a few clicks!
This library provides users with simple alternatives to BYOND's default KEY+REP control scheme. It uses KEY+UP and KEY+DOWN macros as a way to process multiple movement commands at once.

This means you'll be able to add things like diagonal movement, strafing, and movement speed to your game. It's designed to work right out of the box with minimal effort.
I absolutely love this library and find myself including it in every project I work on. It makes movement feel so much better and adds a lot of things people often ask about.
