Get number of columns and rows in tilemap

Based on this question,

Trying to find width of tilemap level

@p3nguinc4g3 How dit you set the tileMapData into a variable? I am also curious to find out what the width and height is. There is a function, TileMapData.isOutsideMap(x, y), but I am not sure how to use it. Instead of defining a tile as the random location the sprite starts at, I want to place the sprite at the bottom and middle of the tilemap. Maybe the width and height of a tilemap works differently than the location of a tile. Maybe if you repost this issue under Arcade | Help, someone els…

I can make a tilemap to be a certain number of columns and rows, but once it’s made, I cannot see a block function to get those values. I have to remember what those values are for each tilemap and then find a location at col/row coordinates.

Knowing the number of columns and rows in block code, I could then place sprites within the timemap (bottom of tile map in the middle) such as

place [sprite] on top of (tilemap col( (tilemap.columns % 2 )) row (tilemap.rows - 1))

Are you talking about placing a Sprite onto one of those (col, row) coordinates?

[Dreadmask197]

This is the tilemap row and column where you can edit the space on how big you want the tilemap to be.

[cosmoscowboy]

Exactly. I need to remember those values for each tilemap I make, and maybe even store that in a variable. I want to be able to call block code to get those values, so that if I change the tilemap, the, code such as:

let centerX = tilemap.width / 2
let centerY = tilemap.height / 2

Still works.

[Dreadmask197]

So you want to turn this as a function and still call those numbers?

[Dreadmask197]

You know like this?

You can always change the numbers on the function so you don’t have to remember as much number I think

I think @cosmoscowboy wants to be able to get the width and height from his code, and not need to hard code the tilemap with and height in his code

[Dreadmask197]

oh. I was just trying to help

[cosmoscowboy]

I like your idea of creating the function, but it is just the same as having called the original code of ‘place sprite on top of…’.

I am just curious to know if you can get the width/height of a tilemap in order to make decisions in code based on those values. Thanks for your help.

You’ll want to use the tilemaps extension for that:

@jwunderl Thanks, I indeed came across that extension, it is very helpful.
