How to make maze walls?

if each wall is a rectangle, you can simplify your coding by creating a parent for the walls and adding rectangular movieclip walls to that parent. 

you could then loop through all the children of that parent checking a hitTestObject between your and the child walls.  if it's negative, store the ball x and y.  if positive, re-assign the ball x and y to the previously stored values.

create your maze.  convert each rectangle in the maze to a movieclip and assign an instance name (eg, m1,m2,...,m44).  don't convert any L-shaped, U-shaped or rotated L-shaped, U-shaped etc sections.  only rectangular blocks.

you can then use:

var prevX:int;

var prevY:int;

var i:int;

var mP:Sprite=new Sprite();

addChild(mP);

for(i=1;i<=44,i++){

mP.addChild(this["m"+i]);

}

function moveBall(evt:Event){

          ball.x -= accelX*30;

          ball.y += accelY*30;

          if(ball.x > (480-ball.width/2)){

                    ball.x = 480-ball.width/2;

          }

          if(ball.x < (0+ball.width/2)){

                    ball.x = 0+ball.width/2;

          }

          if(ball.y > (800-ball.width/2)){

             ball.y = 800-ball.width/2;

          }

          if(ball.y < (0+ball.width/2)){

                    ball.y = 0+ball.width/2;

          }

checkWallF();

}

function checkWallF():void{

for(i=0;i<mP.numChildren;i++){

if(ball.hitTestObject(mP.getChildAt(i))){

ball.x=prevX;

ball.y=prevY;

break;

}

prevX=ball.x;

prevY=ball.y

}

}

}

this line:

for(i=1;i<=44,i++){

should b:

for(i=1;i<=44;i++){

you're welcome.

Hi again, Kglad. I've downloaded this flash file with code for the maze (i too am keen to make a maze), but when i test the movie, the ball fails to move.

Am i missing something?

are you testing on an iDevice?

not at all, am testing on a big pc. And, BTW, when i test the Flash file, an xml file is created. Is that supposed to happen?

check the publish settings.  you're publishing for iOS, that's why flash is creating the xml.

also, that code uses the accelerometer to move the ball.

you need to change both to test ball movement in that file.

Hi. U are right, of course. I got that code and flash file from the above link, and it is set up for mobile devices. As i understand, Accelometer is for mobile devices, and while i changed the publish settings to use Flash as the Player (instead of Air for ios which was how the file was set up), i am wondering if it is possible to use this code as such, on a big PC, not mobile device.

And, i dont know how to change the accelemeter in hte publish settings....

thank you.

yes, but instead of using the accelerometer, use something else (like a keyboardevent listener) to move the ball.

Hi Kglad

I have downloaded http://www.kglad.com/Files/forums/maze.fla

I'm having the same problem as Tixy where just one wall of the left of the maze.fla file has collision, the ball MC just passes through the other walls in the project, is there something I need to change with the checkwall function?
