MoveToGridSpace(ball.x, ball.y); It basically means that in the array grid
that 0=a walkable tile and 1=a non walkable tile. Can i set the array so that
say 2=goto next scene and 3 triggers something else etc? What would the script
be for 2=goto next scene? Thanks

Actually, it is a lot more complicated than it sounds! Not sure if this revised
code will work... Change the stepActions function to however you want. In that
function, steppedOn will represent the number the character stepped on. Also,
don't forget to change the collisions array, and add some 2's and 3's!

function stepAction(steppedOn){
if(steppedOn==0){
trace('You stepped on a normal square!');
}else if(steppedOn==2){
trace('Oh no! You stepped on a 2!');
}else if(steppedOn==3){
trace('You stepped on a 3!');
}
}

Cool, that works great.

So if i wanted it to goto the next scene i have to replace the trace section?

What script shall i put for it to goto scene 2 when its on tile 2?

Sorry, the script i posted first was an old version, i have a new version with
this script: // first set up spacing and collisions spacing = 20; movingTo =

in that you sent back the character wasnt constraining to the area set in the
array. I tried just pasting in the script before the array section and the
character wouldnt walk on tile's with 2 or 3. The goto scene 2 question still
applies aswell.

I changed a few other things in the code, so it won't work. Try this:
First, select Frame 1 of Scene 2, open the properties panel, and type in
scene2_1 as the <Frame Label>
Use this code:

function stepAction(steppedOn){
if(steppedOn==0){
trace('You stepped on a normal square!');
}else if(steppedOn==2){
trace('Oh no! You stepped on a 2!');
_root.gotoAndStop("scene2_1");
}else if(steppedOn==3){
trace('You stepped on a 3!');
}
}

The goto scene 2 works, least thats one problem out of the way. The character
is still not constrained to the area, he was before the new script was put in.
Could this have something to do with the array?

So now the character can go on 1 spaces? Hmmm... Try changing the isValidTile
function to this:

IsValidTile = function(x,y){
trace('You stepped on '+collisions[x][y]);
if(collision[x][y] != 1){
trace('You aren't allowed to step on 1!');
}
if (collisions[x][y] != 1) return true;
else return false;
}

When you run the code, and try moving the character, what is traced?

Then, if that doesn't work try this:

IsValidTile = function(x,y){
if (collisions[x][y] == 1){
return false;
}else
return false;
}
}

My array grid is set up like this: http://www.iso-land.com/movementtest4.swf
I made the array grid so it stays within the floor but with the new script
thats been added tonight the character goes outside the floor. The character
wont walk on the 1 tiles, he just walks everywhere else outside the main floor
even though the grid shouldnt let him. I tried the script you just gave me but
loads of errors come up with it. Thanks

Ahh... then this should work:

IsValidTile = function(x,y){
if (collisions[x][y] !== 1 && collisions[x][y]!=undefined) return true;
else return false;

The character doesn't move at all now, i pasted that script over:

IsValidTile = function(x,y){
if (collisions[x][y] !== 1) return true;
else return false;

How about:

IsValidTile = function(x,y){
if ((collisions[x][y] !== 1) && (collisions[x][y]!=undefined)) return true;
else return false;
}

If that doesn't work, can you try:

IsValidTile = function(x,y){
trace(collisions[x][y]);
if (collisions[x][y] !== 1) return true;
else return false;
}

When you run this code, what is traced normally, and what is traced when you
go outside the boundaries?

Yay, this one worked: IsValidTile = function(x,y){ if ((collisions[x][y] !==
1) &amp;&amp; (collisions[x][y]!=undefined)) return true; else return false; }
Is there any problem you cant solve!!! Thanks very much for the patience and
help yet again!!
