Pretty easy, we're going to do the same thing for the boxesOnScreen array, but we'll also add our collision detection to this for loop.

for (j in boxesOnScreen) {				
	this[boxesOnScreen[j]]._y -= 7;
	if(this[boxesOnScreen[j]]._y < 0) {
		this[boxesOnScreen[j]].removeMovieClip();
		boxesOnScreen.splice(j, 1);
	}

	for(k in ballsOnScreen) {			
		if (this[boxesOnScreen[j]].hitTest(this[ballsOnScreen[k]])) {	
			this[boxesOnScreen[j]].removeMovieClip();
			boxesOnScreen.splice(j, 1);
			this[ballsOnScreen[k]].removeMovieClip();
			ballsOnScreen.splice(k, 1);
		}
	}
}

Code Explanation

Up to the second for..loop everything is the same as the last code snippet that made the ball move, here we are just making the box move and checking if it has gone off the screen. In the second for..loop we'll run our hitTests between each box instance in the boxesOnScreen array and each ball instance in the ballsOnScreen array. If any of the instances collide we remove that instance using removeMovieClip, and we update the arrays.

» Description:

The flash's horizontal road drive was done in CS4 and was upgraded to CS6. The car responds to right/ left key and flash will auto-generate the movement of roads from left-right or right-left based on random number. Have fun driving in this virtual environment and avoid other cars... :) If you are creative, a road driving game can be created from it.
