Intelligent EXE Building

ONIS GAME ENGINE 4.0 examines your project and chooses the appropriate web-game entry automatically. You may select any HTML file, use any filename, and store it anywhere inside your project.

If the project does not contain an HTML file, ONIS can generate a temporary entry from its JavaScript and CSS files without modifying the original project.

The engine then creates its own Windows batch instructions, installs the required packaging tools, uses your computer’s CPU to build the game, and copies the finished portable EXE directly into your Downloads folder.
