[HELP] Maze game using arrow key

ok, so i have made my character and my walls and some other stuff.
but the thing i need help with is my walls. i can get my walls to work.
what i need them to do is if my character touches the wall, he/she dies causing the game to go to the death frame for each different level. oh and may instance for the guy is "dude"

here is the code i have for my guy:

Code:

---

onClipEvent (load) {
moveSpeed = 7;
}
onClipEvent (enterFrame) {
if (Key.isDown(Key.RIGHT)) {
this._x += moveSpeed;
} else if (Key.isDown(Key.UP)) {
this._y -= moveSpeed;
} else if (Key.isDown(Key.DOWN)) {
this._y += moveSpeed;
} else if (Key.isDown(Key.LEFT)) {
this._x -= moveSpeed;
}
}

---

I need help with this as soon as possible.

thanks.

where is your collision check?

Anyway, the simplest way would be to draw the entire wall inside a movieclip, then hitTest it with the player movieclip. The concept is the same as other mouse avoider games.

But if this is tile based, and you are going for a efficient design, you can always check the player's x,y to determine whther he is colliding with a wall cell!

srry bluemagica, but im more of a beginner so if you can maybe help by telling me what to add in my actionscript.
