It is somehow impossible to die in this hitbox testing thingy I did. I'm not sure how, or why it's not registering, but it's not.

Spoiler

local baddies = {}

local maxx, maxy = term.getSize()

for i = 1, maxx, 3 do
	baddies[ #baddies + 1 ] = {x = i, y = math.random( 1, maxy / 2 ), v = math.random( 1, 3 ) }
end

local player = { x = maxx/2, y = maxy - 3 }

function drawPlayer()
	term.setBackgroundColor( colors.green )
	term.setCursorPos( player.x, player.y )
	term.write( " " )
end

local id
while true do
	id = os.startTimer( 0.01 )
	term.setBackgroundColor( colors.black )
	term.clear()
	drawPlayer()
	term.setBackgroundColor( colors.red )
	for _, bad in ipairs( baddies ) do
		local doesMove = math.random( 0, bad.v ) ~= 0
		bad.y = bad.y + (doesMove and 1 or 0)
		if bad.y > maxy then
			bad.y = 1
			bad.x = bad.x + math.random( -1, 1 )
		end
		term.setCursorPos( bad.x, bad.y )
		term.write( " " )
		if bad.y == player.y and bad.x == player.x then
			term.setBackgroundColor( colors.red )
			term.clear()
			term.setTextColor( colors.black )
			term.setCursorPos( 1, 1 )
			print( "You lose!" )
			error()
		end
	end
	while true do
		local event = {os.pullEvent()}
		if event[ 1 ] == 'timer' and event[ 2 ] == id then
			break
		elseif event[ 1 ] == 'key' and event[ 2 ] == keys.right then
			player.x = player.x + 1
			if player.x > maxx then
				player.x = maxx
			end
		elseif event[ 1 ] == 'key' and event[ 2 ] == keys.left then
			player.x = player.x - 1
			if player.x < 1 then
				player.x = 1
			end
		end
	end
end

Go to the sides

local player = { x = math.floor(maxx/2), y = math.floor(maxy - 3) }

Yeah, that's a line of code... but I doubt it causes the problem.

You'll want to check for collisions every time anything moves. I suggest moving that code into a function, then calling it after each enemy movement, and each player movement. Right now, your code only checks every .1 seconds.

LOL, this is actually why it's likely not working. Replace your line 9 with Bomb Bloke's version. One or both of the terminal sizes is likely not divisible by two, so you've got non-integer player coordinates. None of your enemies will be at the same coordinate as the player, ever.

Bomb bloke is definitely correct, 51/2 is 25.5 which renders as 25, but will never line up with the enemies. as a side point, you should probably consider changing the structure of your code to be a little more logical, perhaps a basic game loop could assist you

while true do
  gatherInput()
  updateGame()
  renderGame()
end
