Use Hit Test To Make Walls

Here I'll show you how to use hit test to make a wall in your flash game/movie. First you should probably have your character move so he/she can actually hit the wall. A hit test tells flash what to do once to objects have touched/collided. Like a man and a wall for instance.

If you haven't already viewed the following tutorial I suggest you do.
8 Way Movement Tutorial

1. First make sure you gave your charector the instance name of "man"
2. Then draw your wall (can just be a line if you want)
3. Select your wall
4. Hit "F8"
5. Name your wall and select "Movieclip"
6. Then click "OK"
7. Now skip to the Action Scripting Section below

You will have to put a different action script based on the way your charector will be hitting the wall (from what side). He can hit it from the top, the bottom, the left, or the right. Choose below and add the opproperiate Action Script.

Hit From Above:

• onClipEvent (enterFrame) {
• if (this.hitTest(_root.man)) {
• _root.map._y -=5;
• }
• }

Hit From Below:

• onClipEvent (enterFrame) {
• if (this.hitTest(_root.man)) {
• _root.map._y +=5;
• }
• }

Hit From Left:

• onClipEvent (enterFrame) {
• if (this.hitTest(_root.man)) {
• _root.map._x +=5;
• }
• }

Hit From Right:

• onClipEvent (enterFrame) {
• if (this.hitTest(_root.man)) {
• _root.map._y -=5;
• }
• }

Thats It, Now Test Your Game/Movie!
