Can a Tilemap be displayed wrong?..

Rainfollower

...or does it take cursor position somewhat differently?

I am now doing point-and-click movement, with positions snapped to tilemap.
And when I set navigation visibility mode to "Force Show", I noticed that my units keep moving even if I click within the same tile. Even though they should not! It is the same tile! Must be same array of tiles!
So I added debug output. And it confirmed that clicking within the same tile boundaries, I get different tilemap coordinates.

Here, the screenshots.

First pair of the numbers in Output are the click coordinates, converted with this function:

func global_to_map(global_coords : Vector2) -> Vector2i: # global_coords = to_global(get_local_mouse_position())
	return local_to_map(to_local(global_coords))

I am really puzzled here! I mean, I could make an error in writing snap, but this is very raw coordinates converted to a tile. What could possibly go wrong here? Any ideas, please?..

PS: TileMap transform is (0, 0) just in case, I checked.

Rainfollower could be rounding error for the mouse coord

kuligs2 loss of ~ 16px on rounding? (Tiles are 32x32)/ And with in-built engine functions? Seems a bit too much. no?..

Have you tested

local_to_map(get_local_mouse_position())

directly?

Your conversion to and from global coordinates seems correct, yet I'd still try to rule this out as a source of error.

Dodo_87 yes, I tried that too, thank you.

Okay, I solved this myself.

Q: Did tilemap display wrong?
A: Yes, it did.

Q: Why did it happen?
A: I changed the size of tiles initially, and did not re-create tiles correctly, only tweaked texture_region_size and tile_size — and thought it was okay, because everything looked the same. But it was not okay.

Q: How was it discovered?
A: New test scene with new test tilemap/tileset. But this new scene converted coordinates correctly! So I went through the setup of TileSet and Tilemap again, painted tilemaplayer anew, and this fixed everything.
