This is so noobish… but how do I link to a AS2 class file?
Locally I’m doing this:
import com.gskinner.sprites.CollisionDetection;
and in the same dir of the swf I have the whole “com.gskinner.sprites.” directories.
But how I would do it to upload the swf? How do I point to an online as2 class file? 😑
Bah. Thanks.

you can download his example [fla files at this link.](http://www.gskinner.com/blog/archives/2005/10/source_code_sha.html)
Classes are compiled into the swf when the swf is generated/created. So, they aren’t needed on the web server - than can’t be utilized that way. The import statement needs to be in your fla on a frame - and depending on how he has it set up, you either create an instance of the class on the timeline something like: var foo:TheClass = new TheClass(items may need to get passed in there); or, classes can be linked to movieclips within the library - you can right click on a clip in the library and select linkage - and set things there.
Hope this helps.

```auto
import com.gskinner.sprites.CollisionDetection;
speed = 1;
hit = false;
function onEnterFrame() {
if (CollisionDetection.checkForCollision(leader, room, 255)) {
leader.gotoAndStop(2);
hit = true;
} else {
hit = false;
leader.gotoAndStop(1);
}
// ******************
if (Key.isDown(Key.RIGHT)) {
if (CollisionDetection.checkForCollision(leader, room, 255)) {
leader._x -= speed
} else {
leader._x += speed;
}
} else if (Key.isDown(Key.LEFT)) {
if (CollisionDetection.checkForCollision(leader, room, 255)) {
leader._x += speed
} else {
leader._x -= speed;
}
}
//
if (Key.isDown(Key.UP)) {
if (CollisionDetection.checkForCollision(leader, room, 255)) {
leader._y += speed
} else {
leader._y -= speed;
}
} else if (Key.isDown(Key.DOWN)) {
if (CollisionDetection.checkForCollision(leader, room, 255)) {
leader._y -= speed
} else {
leader._y += speed;
}
}
}
```
That’s my code, but If I upload it to imageshack for example, it doesn’t work. 😕

I’m trying to find out why the collition detection isn’t working. Locally it does, well… not too good…

does the collision detection happen with dynamically loaded images…? or flash drawn movieclips ?

So far with 2 simple MC’s.
“leader” and “room”.
It works… sort of. If you collide and keep holding the key it won’t go through the wall, BUT if you let go and there’s a collision still taking place you can press the opposing key and you’ll go through the wall…
That’s why I want to upload it, so you guys can see what’s up…
