so i want to use the x y(2.7374673, 6.3748372, 0) of the player and change it to get the x y on the tilemap(4,-3) to be used to react to activators and doors, how do i do that?

You can use a collision object to detect when the player touches a certain type of tile: https://www.defold.com/manuals/tilemap/#_tile_source_collision_shapes

Are you interested in something like this?

function tile_id(inst, x, y)--inst is self
	x = math.ceil(x)
	y = math.ceil(y)
	return tilemap.get_tile(inst.TILEMAP, inst.TILEMAP_LAYER, math.ceil(x/TILE_SIZE), math.ceil(y/TILE_SIZE))--TILEMAP & TILEMAP_LAYER is saved as layer on object
end

That’s how I use inside LUA module, but you can config as you want.

This function converts world position to tilemap position and return ID of tile.

The function assume the tilemap is at origin and not rotated, right?

Kinda. It simply converts world position to tilemap position. In the world, tiles might be 16x16 or whatever, but in tilemap, they are like 1 pixel wide.
You can read a bit more here.
