Soo is it possible to do this?

Thanks for a fun and edifying challenge, @marioeligi!

What I also myself found immediately unintuitive, was that one cannot directly compare two Tiles OR two Tile Location objects directly to eachother, like you attempt with this statement:

The reason seems to be that two (instances?) of an object can not be equal and there is no _.isequal() method defined, as discussed by @cosmoscowboy et.al. here:

Locations and Objects

I am not completely sure how Javacript compares objects, so I am assuming the comparison you are trying to make might point to the same tile in the game, but are two separate objects. Being two separates objects that may not be equal, even though conceptually they point to the same tile in the game.

But there are other working solution which you could use, some of which I have played around with in this example:

plez halp alternatives

1. Compare both the column and row(or y and x) properties of the Tile Location Objects in the arrays and the tilemap location object of mySprite, respectively, against eachother, which give unique enough comparisons,
2. Put the Tile Images in arrays instead of the Tile Location objects of the Tiles and compare those instead against the image of the tile that mySprite is on, or
3. Keep Tile Location objects in arrays and compare the images of these to the image of the tile that mySprite is on.

All 3 above work with varying degree of efficiency, but you can see for the green grass tiles, that none of the direct object comparisons work.

There are probably other and more efficient ways to do this, but that would be a question for other more experienced forum members. I never, for instance, figured out @NightIsland’s myTile.tileSet methodology for the same type of comparisons discussed here:

How to test when player is over a certain type of tile?

I’d like to ask for something else, if I may: it’s not always practical to create a sprite for every type of a tile; for instance, in a game that has a lot of water and a lot of land, detecting whether you’re flying over land would be very silly to create a sprite for every land tile. So I’d like to return to the original question, and ask ‘how can I detect what type of tile is at position X,Y [or underneath an existing sprite’s position, or whatever)?’ It would be perfectly acceptable, for my…
