if your road is close to rectangular or can be approximated by several rectangular shapes you can use the hitTest to determine when your character goes outside the rectangular shapes.

if you want more accuracy or can't use rectangular shapes, you can use the bitmapData's hittest.

if(!man_mc.hitTest(road_mc)){

// do whatever. your man is completely off the road

}

right now i have just add an alert box as shown below to check whether the script is working or not.

this.onEnterFrame=function(){

if(!man_mc.hitTest(road_mc)){

Alert.show("Hit!!!");

}

};

But it is not working...i have added this script on instance of man_mc.

try:

trace("Does not hit!!!");

instead, it will work.

Yes, the ! means NOT

so:

IF NOT HITTEST = TRUE THEN

TRACE "Not hitting"

END IF

use:

trace(man_mc);

trace(road_mc);

this.onEnterFrame=function(){

if(!man_mc.hitTest(road_mc)){

trace("off");

}

and move your man_mc completely off of road_mc. copy and paste the first few lines of the text in your output panel.

1. you should mark helpful/correct answers.

2. what do you want to click to trigger a hittest?

3. what do you want to click to move your man_mc?

4. in what direction do you want to move man_mc when whatever you answer in 3 is clicked?
