Swapping x +,- coordinants with hittest.

[cdrake]

I can use code like this it will only work for the first time it comes in contact with it. I am wanting to know how I can make it self aware of what direction it is going and automatically go the opposite direction when it hits something.

onClipEvent (enterFrame) {
if (hitTest(_root.sbg) == true) {
_x += _root.sbgspeed;
}
}

My code just assumes that the clip is moving to the left at all times which would not be true after it hits the sbg clip and starts going right.

I know it can be done. I just need a little push :p

[Billystyx]

onClipEvent(load){
//initial direction
dir="left";
}
onClipEvent (enterFrame) {
if (this.hitTest(_root.sbg)) {
if(dir=="left")_x += _root.sbgspeed;
if(dir=="right") _x -=_root.sbgspeed;
}
}

and change 'dir' to match when you move the clip's direction.

That wasnt exacly what I was looking for but I did realize something when trying out your code though.


onClipEvent (enterFrame) {
if (hitTest(_root.block2) == true) {
_root.speed = -_root.speed;
}
if (hitTest(_root.block3) == true) {
_root.speed = -_root.speed;
}
}


This is what I was wanting but I was trying to make it more complicated than it really was. The only problem with the code is that I can only use it for one instance of a movie clip. If I put the code in any other ones they all just start shaking back and forth.

Is there a way I can make it work without giving each movie clip instance its own speed variable?

I tried adding code like this but it didnt work.

onClipEvent (load) {
_root.block1 = _root.speed;
_x += _root.block1;
}


thanks.

I have this in Clip 1

onClipEvent (load) {
_root.block1 = _root.speed;
}
onClipEvent (enterFrame) {
_x+=_root.block1
if (hitTest(_root.block2) == true) {
_root.block1 = -_root.block1;
}
if (hitTest(_root.block3) == true) {
_root.block1 = -_root.block1 ;
}
}


and this in clip 2


onClipEvent (load) {
_root.block2 = _root.speed;
}
onClipEvent (enterFrame) {
_x-= _root.block2;
if (hitTest(_root.block1) == true) {
_root.block2 = -_root.block2;
}
if (hitTest(_root.block3) == true) {
_root.block2 = -_root.block2;
}
}


The two movie clips just glide on past each other for some reason.

A few things are odd with your code. I attached something that works.

By the way, you really don't need to path to the _root if you're coding properties of the parent clip. Meaning, use "_x" or "this._x" instead of "_root.myClip._x".

ahh. I see. thank you for the help.
