Why Simplex Engine 3

Ever worked with GameMaker: Studio? Simplex is aiming to provide a modern, modular, GM:S like environment. Define objects, override events, assign actions, place instances into the room editor. You know the drill. We are taking this intuitive workflow to the next level. Learn how.

Unique value

Room editor runs in 60 fps and all objects are equipped with an additional set of in-editor events. That means you can do anything right in the room editor. From simple stuff like changing ImageIndex on runtime to physical simulation. Anything, rendered via DirectX12, 3D accelerated.

SGML aka GML++

Do you like Game Maker's scripting language as much as we do? So simple to use, right? We are taking GML where noone before - function by function we've implemented almost entire GML into C#, improving each and every function where possible. Ever wondered why draw_rectangle has no angle argument, why instance_find don't accept a predicate or why you can't set shape nor opacity of the game window? Use modern C# constructs and simple GML actions side by side.

All the editors you are used to

Manage all your resources easily with our code, sprites, audio and room editor. Modern looking, dark themed, multi-display aware, ready for 8k forms. Several times faster project loading, using less memory and processing time, utilizing .net framework 4.8

Every single inch modular

Ever wanted to modify right-click instance menu in the room editor? Pair automapping with masks generation, visually edit attributes? We hear you, taking all you know from GMS one step further.

Source control ready

Develop in teams and fear of the merge conflicts not. Simple, efficient project structure allows for painless source control and continuous integration.
