i hope someone can help, i am stuck and i am a fairly mid level actionscripter so this is something i haven’t done before.

i have a little crab movie clip on the bottom of the ocean floor in a scene.  
i want the crab clip to avoid the mouse on the x axis only and i want it to be contained to the edges of the movie. i have found info on doing this on both and x and y axis and without being contained. i have also found info on this but without any gravity or friction to it which we need.

any help is much appreciated!

thanks,

basically, wouldn’t you just make the crab accelerate towards the side of the movie the mouse is farthest from?

Something like this:  
if you have a restriction on the crab’s left and right boundaries

var crabMin:Number = 0;  
var crabMax:Number = 100;

Then you check the current mouse position, and see whether it’s closer to the left or right.

var currentMouse:Number = \_xmouse;  
if((crabMax - currentMouse) \> currentMouse){ //Meaning the crab is more to the right  
// than the left (I think 🙂 )  
crabMC.\_x += (.98) \* crabMC.\_x;  
} else {  
crabMC.\_x -= (.98) \* crabMC.\_x;  
}

I think that may do it, but I haven’t actually tested that. Oh. and the .98 corresponds to friction. And the reason it’s greater that currentMouse is that crabMin is 0. Otherwise, it’d be a bit different.

If you’re willing to wait a while, I may get around to testing that. Otherwise, ask questions if you have them, and have fun. 🙂
