a$.$ Correct behavior: i$.$ All monsters with a vertical or horizontal line of sight to the player move $1$ tile closer to the player $1.$ Starting from the tile above the adventurer$$s location and working upward, check each individual tile to see if there is a monster on the tile. $2.$ If there is a monster on a tile, move the monster one tile closer to the adventurer. $3.$ Continue to check until you have reached the top of the map or reach a pillar $($monsters can$$t see through pillars$)4.$ Repeat the same logic with down, left, and right $($in that order$).$ Make sure all monsters that are supposed to move do so before you go to the next step. ii$.$ Return true if a monster reaches the player, false otherwise. $1.$ The adventurer is killed if a monster moves onto their tile $($check if the player position now contains a monster$),$ return true $($adventurer killed, game over$)$ if so$,$ otherwise return false $($the monsters did not attack the adventurer, yet...$).$
