Hi everyone,

I'd like to know how I could make something move along an ellipso�dal path like in the menus you can see in the secret of mana serie... I've tried to make it but I think it shall need an equation on the movement to work properly.

Thanks in advance.

Probably the easiest way would be to use the path behavior set to curved.

Just add a node at the start, mid, and end points, then set its position on the path to 0, and start.

set position to

x: origin.x+cos(angle)*(ellipse width)

y: origin.y+sin(angle)*(ellipse height)

origin would be the point you want at the center of the ellipse, angle is an angle from 0-359 (well it can be anything really, but thatll just loop it back since its an angular value after all)

the other parameters are pretty self explanatory. to make it spin you just need to alter the angle value.
