iscEngine is Update

Fusion Script Game Studio: iscEngine & JS-Engine · published 3 Dec 2025, 21:22 UTC · build 21043860

All newsPlayers around this dateRead on Steam

iscEngine has been updated. Both the game engine and your games will now run more efficiently. New commands have been added, and the code editor has been improved.

Changes:

Application performance has been improved.

It now supports nested structures like if ... end if, loop ... end loop, for ... next, while ... wend, and switch case. In previous versions, nesting these commands would not work properly. This problem is no longer present.

New string functions have been added, including: left, right, mid, strlen, etc.

New math functions have been added, including: abs, sqrt, floor, ceil, round, pow, log, min, max, sin, cos, tan, etc.

File operations were also possible in previous versions, but we didn't include this in the syntax section. You can see an example there now.

In previous versions, the code editor was slow and took a long time to highlight keywords. This is no longer an issue. Now it runs much faster and looks better.
