The note seems to be a cut and paste copy of the one for playdate.graphics.tilemap:getTileAtPosition(x, y)
:
Tilemaps and imagetables, like Lua arrays, are 1-based, not 0-based. tilemap:getTileAtPosition(1, 1) will get the index of the top-leftmost tile.
What was probably intended was a note related to setTileAtPosition()
instead.
