Rotation

A Rotation is an alteration that will rotate a sprite around its center point. It has a number of interesting options in order to get your sprite oriented how you want it.

When applying a rotation to a child sprite, the angles are relative to the sprite's direct parent sprite, not the screen.

create routine as Start launch spinner end

create sprite from windmill-180x180.png as spinner
  where center=90,90 and x=350 and y=160
  having alt=rot1
end


create rotation as rot1
  where speed=-100 distance=720 easein20 easeout=40
end

Parameters

speed={number}: speed of rotation in degrees per second. This can be a negative value to rotate clockwise.
distance={number}: the distance to rotate - positive values only - speed sets direction.
OR,use distance=short to travel the shortest distance to the given destination. In this case, the sign of speed is ignored.
destination={number}: rotate until this angle is reached
toward={number},{number}: rotate until pointing at this x,y coordinate
easein={number}: gradually increase speed over this distance (in degrees).
easeout={number}: before reaching distance, gradually decrease speed over this distance (in degrees).
completion={routine}: specify a routine or another alteration to run when the rotation stops
