Hi, I’m hoping that someone is able to help me with my problem. I am creating a system for children to encourage mouse based navigation. The interface is based on a street map with a number of houses on it, and its up to the kids to move a car around the street map. There are 2 navigation methods that need to be made:

1. The car needs to follow the mouse but it only move within a certain area i.e. the on the road and not over the houses or any other part of the interface that isn’t a road. The code I have is below, but I dont know how to edit it:

onClipEvent (load) {  
\_x = 0;  
\_y = 0;  
speed = 15;  
}  
onClipEvent (enterFrame) {  
endX = \_root.\_xmouse;  
endY = \_root.\_ymouse;  
\_x += (endX-\_x)/speed;  
\_y += (endY-\_y)/speed;  
}

1. The car needs to move to the point where the mouse is clicked, but the area is restricted only to the roads. The code for this is below, but again, I dont know how to edit it so that the car will only move within the road area:

onClipEvent (load) {  
\_x = 0;  
\_y = 0;  
speed = 15;  
}  
onClipEvent (mouseDown) {  
endX = \_root.\_xmouse;  
endY = \_root.\_ymouse;  
}  
onClipEvent (enterFrame) {  
\_x += (endX-\_x)/speed;  
\_y += (endY-\_y)/speed;  
}

I hope that makes sense! I know it can be done, but I don’t how to do it, as I have just started using Flash.Can anyone help me please??? Thanks
