Whats the matter with this (tilebased) issue ?

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

Code:

---



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;

In this part:

Code:

---

// 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.


-genesis f5

j is defined in the bulid map function

Code:

---



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?

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
