SetDisplayAspect( 4.0/3.0 )
setvirtualresolution(480,480)
CreateSprite ( 1, 0 )
SetSpritePosition ( 1, 130, 200 )
AddSpriteAnimationFrame ( 1, LoadImage ( "spaceship1.png" ) )
AddSpriteAnimationFrame ( 1, LoadImage ( "spaceship2.png" ) )
AddSpriteAnimationFrame ( 1, LoadImage ( "spaceship3.png" ) )
AddSpriteAnimationFrame ( 1, LoadImage ( "spaceship4.png" ) )
rem Main Loop
