LÖVE

I have a line of sight algorithm, however when checking the players (x,y) and the enemys (x,y) against the table of blocks it only returns nil (no LoS) When all blocks are in the way of the LoS, eg:

P - Player
W - Wall
E - Enemy

P--------W-----E----W (LoS = true)

P-------E-----W-----W (LoS = true)

P ----------W----W-----E (LoS = false)


I've included the love file,
wasd to move, green background = no LoS

Fixed it for you. The problem was that you effectively only checked the last block, because all earlier checks are undone.

Thanks
