Note: This is the WD17 + compatible version, from the WD25 project posted here
https://depot.PC SOFT.fr/resource.awp?file_id=281474976711146;demoscene

The code of this version is slightly different from the 25+ which is more responsive in handling callbacks.
The Skin used is different, as well as the main soundtrack which uses a "music tracker" in .mod format (inherited from the Amiga) particularly popular in the DemoMaker community for its very small size.

You can change the main soundtrack here:
IF gB.Monolith = 0 THEN // Specific to WD17
gB.Monolith = 1 // Specific to WD17
gB.AudioFile = EXEresource () + "MANDFORC_ (1992) .MOD" // Main audio theme
BassChannelPlay (gP.hMain)
gB.Monolith = 2 // Specific to WD17
END
The supported audio formats are:
.mp3, .wav, .ogg, .aif, .mo3 , .it, .xm, .s3m, .mtm, .mod, .umx.

StarGate is the transposition of a GDImage project written in C++ (available on the private forum www.objreader.com).
You can limit the size of the WINDEV framework as much as possible (only MAT, STD, VM), because everything is coded directly with the flat API in procedural mode to boost performance.
The SinAPI and CosAPI functions perform on-the-fly conversion from degrees (WD) to OpenGL radians.

This code is for those who like to get their hands dirty and want to test low level programming in WL.
