Scratch

If sprite 1 is revolving around sprite 2, and distance is the distance between them, than do this in sprite 1:

[blocks]
<go to[ sprite2
<point towards( mouse
<move( distance )steps>
[/blocks]

There are more complex formulas, but I don't feel like going into them right now.

Well call me the most confused person alive.  I can make a sprite revolve so it goes directly away from the mouse, but not towards.

When I try to make it go the other way it glitches out and the sprite flies everywhere.

???

EDIT:  Wait, I think I have it.  Gimme another minute, please.

Wait, I have it!  Sorta.

Only one glitch where when you mouse your mouse under the center sprite that doesn't move, your sprite goes the other way.  The end result is the same but it takes the long route around.

Agh, wish I could understand the script D: . Oh well, thanks  .

Just import it, then you don't need to know!     (That came out a little meanly, sorry)
Oh, and wherever it says [x positon] of [Sprite 2], change the [Sprite 2] to the sprite you want it to revolve around.

<when green flag clicked>
<forever>
<go to[ Sprite1 ]>
<point towards( Mouse pointer )>
<move( 100 )steps>
<clear>
<stamp>

Close, but that would make it point, not rotate, right?

It would stay exactly 100 pixels away from the centre sprite closest to the mouse.
Like there's an circle with a radius of 100 around the center sprite that the moving sprite must stay on, but it trys to stay closest to the mouse.

I just realised floppy said this before, but this will make it less flashy.

Yes, but what I'm saying is it won't rotate, it will just immediately be where it needs to be in one frame, instead of slowly moving towards where it should be.

Actually, I described it incorrectly- I meant more of what colorfusion did (sorry). Still, I have one problem with colorfusion's- it clears the stage. What I'm looking to do requires the stage to be stamped and it can't be cleared. Could someone make something that looks exactly like colorfusion's but doesn't use stamp or clear?

Darn.

CURSE YOU, SIMPLICITY MAN!!!! *evil fist-shaking*

Just get rid of the stamp and clear and it should work the same.

xD sorry. Works  . Thanks!
