There are two stationary balls-ball A and ball B. There is another ball- ball C, which has to move from ballA to ballB.

The problem is that when the I “run” the movie, ball C is automatically placed at the position of ballB. That is, I do not see ball C moving from the position of ball A to the position of ball B.

I have used a line-drawing algorithm to move ball C. Also, the entire stuff is written in Actionscript.

PS:this.\_x++ and this.\_y++ will not work because ballC has to travel the exact path between the two balls

ballA and ballB are of green color and the ballC is of red color.

you could look into the library.

Important:i want to see the ballC move from ballA to ballB.So I initially place ballC at ballA position and I wrote the actionscript to move ballC to ballB but when I run the script, I see ballC at ballB.

many thanks for opening the .fla

onClipEvent(enterFrame){  
diffx=\_root.ball2.\_x-\_x  
diffy=\_root.ball2.\_y-\_y  
\_x+=diffx/5  
\_y+=diffy/5  
}

This will give it some easing also.
