if you mean rotating to face the mouse then use
Code: Select all
angle=direction(x,y,xmouse,ymouse)/nframes;

But for some reason xmouse and ymouse always tend to be off so your better off making an actor called mouse and on create actor setting it to follow mouse then change the turrent code to
Code: Select all
angle=direction(x,y,mouse.x,mouse.y)/nframes;


EDIT: Put this in draw actor

xmouse and ymouse are screen coordinates. So to use them, use
Code: Select all
direction(xscreen, yscreen, xmouse, ymouse);


In you're example, you're adjusting angle. angle is for movement, and requires directional_velocity.
If you want to adjust the animation use
Code: Select all
double dir = direction(xscreen, yscreen, xmouse, ymouse);
animpos = (int)((dir + 5) * .1) % 36;

This is for a 36 frame rotation animation (for other values you'll need to adjust the numbers.

the animtion of your turrent rotating should start at zero degrees (facing right) and rotate counterclockwise in order for the code to work :)
