A grid-locked object is always aligned with the grid. That means its location is normally exactly equal to that of one of the grid squares, so all you have to do is find which grid space has the same co-ordinates as the player.
If you've been smart about it, you can find the map square at the player's location using something like map[player.y / gridsize][player.x / gridsize].

I can.
Code: Select all
function love.load()
player = {
x,
y,
ySpeed = 0,
grav = 1.5
}
map = {
