Definition

INT angle

Angle is a predefined local variable which holds the angle (measured in 1/1000 of a degree) at which the graphic of that process (assigned by the local variable graph) will be drawn. It also influences the result of the function advance().

Example

To make the graphic of a process spin:

Program spinning_graphic;
Begin
    graph = new_map(100,100,8);  //Create a cyan square and assign it to 'graph'
    map_clear(0,graph,rgb(0,255,255));
    x = 160;     //Position the graphic's center
    y = 100;     //in the center of the screen
    Loop
        angle += 1000;    //increase the angle of graphic by 1000 each frame. 1000 = 1 degree.
        frame;
    End
End

This process will spin the cyan square by 1 degree each frame.
