Please what is ofIndexType ? Thanks

it’s either

GL_UNSIGNED_INT
or
GL_UNSIGNED_SHORT

depending on what platform you are on (iOS, Desktop, etc)

Depending on the IDE you are using you should be able to just right click it (or the equivalent) and jump to the definition, I use it all the time in Xcode and Visual Studio.
