Circle Offset for Leg Movement (Solved)
Solved by myself. Just put the trig blocks together randomly and got it.

Hi all, me again.
I'm trying out an animation technique for the movement of legs in an NPC character for my next game (if this works).
Basically, I have the main body of the character, "Char".
I then have two legs (which move in the same way, so I'll only portray one) which follow "Char" around, but moving in constant circles.
Here is my script so far:

I need Xoff and Yoff to change accordingly, as if they were actual position variables, to end up with a circle path. Diagram:

Get it?
I imagine we need some trig, but I'm getting there next month. For now, I have to rely on the kindness of strangers. Let's hope there's some left
Thanks!

Re: Circle Offset for Leg Movement (Solved)
I can help you with this. If it's direction does not have to be a specific thing, click the square button to the left of the sprite at the top above the scripts, and use this:
Put that in the forever block. Change the 5 at the ends to adjust how far the leg should be from the center, adjust how fast it turns to change, er, how fast it turns.
However, if the direction of it is important, add this in:
And get rid of the turn block. Replace the 
pieces with 
pieces.

Thanks heaps! It worked really well and I just locked its direction. I don't think I'll need more tweaking, it shouldn't become an all-animation project.
