What can it do that others can't?

The engine was built specifically to create a game that feels like a complex god world or an ant colony simulator. Lot's of things going on all at the same time; this looks super fun and chaotic and allows for the game to grow extremely quickly in complexity, without the core gameplay changing much.

Run desktop-like simulation games in the browser
Developed with performance in mind, the entire engine was developed to run in a threaded capacity, using webworkers to relay messages between threads. This means multiple AI and tasks doing multiple things at once.

Complex object management database
A complex management database especially crafted for games with many many objects.

Complex AI State machine
Built from the ground up after many iterations, the AI state machine allows you to plugin direct statements to what you want an agent to do. This can include healing when low health, attacking players and chasing players.

Paths & Grid built in
Custom made grid system which can be any size, we can get really enormous maps with this chunk based system. Path finding is also built in with additions to the EasyStar library.

Complex UI State and Management
Our experimental UI allows you to use the same assets directly from the game within your UI, no other pipeline tools required. You can directly call UI components with one line and re-use them whereever you need.

The engine can be used to develop rich experienced for both desktop and mobile with a speciality towards 5G delivered content.

The engine uses the latest technologies to deliver its logic and rendering, this includes WebGL and Webworkers in a multi-threaded environment (even for the browser/mobile)

The UI is entirely integrated into the toolkit and is developed using PixiJS components. It is also entirely optional to create custom HTML or React based UI's on top of the game.
