oIrrlicht is example of Irrlicht usage with objects where funcs aren't exposed (till rev.4) and with funcs exposed for DllCall (from rev.5 and AutoIt examples).
While rev.1 (object version that did not have renamed func object names) is lost, rev.4 UDF (last version with objects) folow similar principes and serve as a good start point for anyone as showcase that other languages can access IrrLicht from objects.
From oIrrlicht rev.5 usage and examples on exposed DllCall funcs will be updated from time to time.
Note that oIrrlicht target audience isn't a new user to AutoIt. oIrrlicht doesn't have help file for AutoIt like au3irrlicht2 but instead it try to folo Irrlicht func usage and coding practice. While dll lacks some exotic functions like grass - cloud animators and XEffects that au3irrlicht2 have, oIrrlicht try to use last Irrlicht version and try to have larger variety of original Irrlicht funcs exposed like VolumeLightSceneNode andvance GUI functionality and similar...
great program autoitoirrlicht, thanks.
