Enum octopt::ScreenRotation

#[repr(u16)]
pub enum ScreenRotation {
    Normal,
    ClockWise,
    UpsideDown,
    CounterClockWise,
}

Possible orientations of the display. Note that this should only affect the visual representation of the screen; draw operations still act as if the screen rotation is 0. Only used by some Octo games.

Variants

Normal

Normal landscape screen display, used by 99.9999% of CHIP-8 games

ClockWise

Portrait screen display, ie. a normal screen rotated 90 degrees clockwise

UpsideDown

Upside down landscape screen display

CounterClockWise

Portrait screen display, ie. a normal screen rotated 90 degrees counter-clockwise
