How can I make a sprite orbit the mouse? Had a nifty idea, although I'm stuck on how I can get this to work. I'm guessing it has to do with some clever maths? I tried messing around with the sin, cos and tan values of a variable and placing the sprite at the mouse's position +/- the value of that 'equation'. Something along the lines of:


I have a variable which I simple use like a form of 'for' loop in the do/loop:


I have attached a VERY primitive picture showing what I want to acheive

Try using a Revolute joint about an invisible sprite to get the visible one rotating about the invisible one.

Then make a Mouse joint between the invisible sprite and the pointer.

Thanks! to both of you, I think I'll use the non-maths method, seams to be simplest to control.

+ to Marl since that would ensure the face of the moon visible to earth wouldn't change. Keep it real

I would also like to point out however, in all fairness to reality, that the moon's orbit is elliptical

My code handles that.

Change the values of Size# in the x and y statements to different numbers to create elliptical, or even figure 8 orbits. (Or wavey ones, or crazy ones, or see saw ones lol)
