Whats the matter with this (tilebased) issue ?

[hooligan2001]

I was mucking around with the out of society scrolling and i tried to get it to scrool up and down but in my attempts i still cant work it out here the code the stuffed up bit is //commented with //up //down

take a look

fscommand ( "allowscale", false );

// includes the map array from an external file
#include "map.as"

// how big is our map?
mapW = map1[0].length;
mapH = map1.length;

// the visible area, what we should draw.
visAreaX = 10;
visAreaY = 9;

// the tiles width and height
tileW = 16;
tileH = 16;

// the x and y positions where our map should be positioned on the stage
startX = 140;
startY = 40;

// used later on for the actual scrolling
majorX = 0;
majorY = 0;
scrSpeed = 3;

// attach an empty movieclip from library, inside this we draw our map.
this.attachMovie("empty", "scrClip", 0);
this.scrClip._x = startX;
this.scrClip._y = startY;

// attach a cover, to make it look smooth
this.attachMovie("cover", "cover", 1);
this.cover._x = startX;
this.cover._y = startY;

// buildMap-function
function buildMap () {
	// i = Height loop || j = Width loop
	for ( i=0; i<(visAreaY); ++i ) {
		for ( j=0; j<(visAreaX+1); ++j ) {
			this.scrClip.attachMovie("tile", "t_"+i+"_"+j, ++d);
			this.scrClip["t_"+i+"_"+j]._x = j*tileW;
			this.scrClip["t_"+i+"_"+j]._y = i*tileH;
			this.scrClip["t_"+i+"_"+j].gotoAndStop ( map1[i ][j][0] );
		}
	}
}

buildMap();

// scroll-function
function doScroll (dir) {
	// right
	if ( dir == "right" && j <= mapW ) {
		this.scrClip._x -= scrSpeed;
		majorX += scrSpeed;
		if ( majorX >= tileW ) {

					removeMovieClip ( this.scrClip["t_"+lasti+"_"+(lastj-visAreaX-1)] );
				}
			}
			++j;
			majorX -= tileW;
		}
	}

	// left
	if ( dir == "left" && (j-visAreaX) > 0 ) {

In this part:

// how big is our map?
mapW = map1[0].length;
mapH = map1.length;

was mapH supposed to be mapH = map1[J].length; ?


just wondering, since I hadn't seen "J" defined in the initial code.

j is defined in the bulid map function

function buildMap () {
	// i = Height loop || j = Width loop
	for ( i=0; i<(visAreaY); ++i ) {
		for ( j=0; j<(visAreaX+1); ++j ) {
			this.scrClip.attachMovie("tile", "t_"+i+"_"+j, ++d);
			this.scrClip["t_"+i+"_"+j]._x = j*tileW;
			this.scrClip["t_"+i+"_"+j]._y = i*tileH;
			this.scrClip["t_"+i+"_"+j].gotoAndStop ( map1[j][0] );
		}

Heh, I guess Ed Mack edited your post and changed what was wrong in the code then?

[hooligan2001]

Dont think he did he just minimise my code due to the fact it was so big

if anyone can fix my problem please be my guest

I just put a small tag on it ... Check my site in a few days for scrolling help (If you're on my mailing list, then you'll be told about it)

k thanks heaps ed
