flash actionscript:

let's say your stage is 640x480 and your movie clip you are moving is called
car_mc:
code on main timeline:
this.onEnterFrame=function(){
if (car_mc._x>=640-car_mc._width|| car_mc._y>=480-car_mc._height){
//we know the car is outside of view, you can call a new function
that changes variables and changes direction of the clip
}
}

there's a much simpler way to do it...... without code.

MASK the layer that has the car in it:

1. Put a layer above your car layer.
2. Draw a box that covers the stage.
3. Right click on this layer and select mask.

It will automatically mask the layer directly below it and the car will only
appear on the stage, where that box is drawn.

Now you have two ways to go! =)

First of all, I wannaFlashU- My way is better because your movie clip will
go off stage and cannot be rerouted to stay on the stage. It will not be
seen when entering the mask, but it will keep animating forever.

wildteen- You need to place my code this.onEnterFrame=function(){ code on
the maintimeline, make sure you are placing this code on the main root
timeline, not the button or movie clip itself.

Todd, when i first read the name of this thread and the initial post, I thought
he had everything working except the car was seen going off of the page (beyond
the stage) and thats what I was addressing.

Of course you have to have code to either bounce the car back the other way or
make it appear entering from the opposite side of the screen (ala asteroids) -
I thought he already had that code in his project. I misunderstood.

speaking of asteroids, here's a link to the tutorial on making that and some
of the ideas in there may give you some help on this project as well.
