MouseLock & PointerLock for GameMaker
(click for web demo)
I made a small GameMaker: Studio extension that provides a unified API for "mouselock" between desktop and web (html5).
The way this works is by utilizing built-in mouse snapping functions on desktop targets, and using Pointer Lock API on HTML5. It bridges between the two, and you get simple functions like mouse_lock() , mouse_unlock() , and mouse_delta_x & mouse_delta_y for getting the mouse movement offset while mouse is locked.
So, if you ever wanted to make some web-based first-person shooters (or just games with mouselook) with GameMaker: Studio, now you can.
The extension is free and can be downloaded from itch.io or GameMaker: Marketplace .
