HELP - dude, wheres my hitTest?

Hi all,

I hadthis problem a while back, so Im putting the question to you experts. I need my small npc dudes to walk the opposite way whenever they hit a wall (North, South, East or West). I've ued hitTest on the guy, and he moves up the screen towards the test wall where he hits it and doesn't move in the opposite direction (despite my best scripting attempts - Below).

onClipEvent (load) {

dudeSpeed=5;
this.gotoAndStop(1);
}

onClipEvent (enterFrame) {

this._y-=dudeSpeed;

if (this.hitTest( _root.wall ) ){
this._y=
this._y+=dudeSpeed;

}


}

It compiles correctly, runs correctly, but when it reaches the "Wall" MC, it just stops in its tracks. Doesn't move down the y+ axis as requested.
Any suggestions? Much appreciated :)

The reason it stops in its tracks is because you've told it to go left at a speed of 5. Once it hits the wall you've then told it to go right at a speed of 5. The only thing is it's still trying to go left at a speed 5 making its current speed actually 0, so that's why it stops dead in its tracks.

You should try coming up with a function to allow the NPC to move in a random direction (for a random amount of time) and once it hits something, make it's direction change via a direction variable rather than trying to affect its speed.

You might also wanna check out:

code:

---

this._y=

Not sure why its in there, but it definatly cant be helping matters.

Actually, tis up and down, and I know about the function :P question is: how?? Oh, and the this._y= was a typo, didnt really affect it.

shouldnt you just be able to change DudeSpeed?

if(this.hittest(_root.wall){
DudeSpeed=(-5)
}
