Help with collision/overlapping with tilemap

I have a problem and i cant get it right.

What i need to solve is how to find which tile a sprite is overlapping.

Example

Lets sayI have a tilemap with 2 different tiles with tile id 0 and 1.

Lets make a map of these two tiles and then put a sprite on this map

Now i want to see if the sprite is overlappin a tile with id 0 or 1 when i move the sprite around.

What is the best way to do this?

Do you want to know the exact tile (0 or 1) that is overlapping the sprite or if the sprite is overlapping visible tiles at all?

If you only want to know if the sprite is overlapping a visible tile, independently from the number. You need only:

+ Sprite: Is overlapping Tilemap

-> ...

I need to know the exact tile. If its on tile 0 or 1

Use the expression:

TileAt(PositionToTileX(sprite.x), PositionToTileY(sprite.y))
