I am working on a c++ engine that handles rts so I can easily make multiple rts. I wish to make it accessible to others but right now there is absolutely no documentation and license so it remains for my personal use. I am plugging it in Godot to create a first rts using it more as a technical demo than anything for now, here it is : https://simonpicarter.itch.io/fair-and-square
There is also a devlog here on how I handled collision avoidance and movement https://simonpicarter.itch.io/fair-and-square/devlog/540419/movements-and-collis...
I am happy with the progress, working on the multiplayer bits for now, I hope to be able to publish a real first demo on steam by the end of summer but you can already feel the engine working.
Once the engine is in a nice place I may try to use it for a short jam to evaluate how easy it is to use it.
