my screen is black

there is nothing on my screen when i run my program. here's my code: PLAYER_SPEED = 6 APPLE_SPEED_MIN = 2 APPLE_SPEED_MAX = 5 SPAWN_INTERVAL = 0.8 PLAYER_WIDTH = 40 PLAYER_HEIGHT = 12 APPLE_RADIUS = 6 START_LIVES = 3

func init() -- player variables player_x = 0 player_y = screen.height/2 - 40 player_w = PLAYER_WIDTH player_h = PLAYER_HEIGHT

-- apples: each apple will be [x, y, vy] apples = new [] spawnTimer = SPAWN_INTERVAL score = 0 lives = START_LIVES gameOver = false .

func update() if gameOver then if keyboard.SPACE then init() . return .

-- player movement if keyboard.LEFT or keyboard.A then player_x -= PLAYER_SPEED . if keyboard.RIGHT or keyboard.D then player_x += PLAYER_SPEED .

-- clamp to screen halfW = screen.width/2 if player_x < -halfW + player_w/2 then player_x = -halfW + player_w/2 . if player_x > halfW - player_w/2 then player_x = halfW - player_w/2 .

-- spawn apples spawnTimer -= 1/60 if spawnTimer <= 0 then spawnTimer = SPAWN_INTERVAL ax = rnd(-screen.width/2 + APPLE_RADIUS, screen.width/2 - APPLE_RADIUS) vy = rnd(APPLE_SPEED_MIN, APPLE_SPEED_MAX) apple = new [ax, -screen.height/2 - 10, vy] apples.push(apple) .

-- update apples for i = apples.length-1 to 0 step -1 a = apples[i] a[1] += a[2] -- y += vy caught = false

-- check collision with basket
if a[1] >= player_y - player_h/2 - APPLE_RADIUS then
  left = player_x - player_w/2
  right = player_x + player_w/2
  if a[0] >= left and a[0] <= right then
    score += 1
    apples.remove(i)
    caught = true
  .
.

-- missed apple
if not caught and a[1] > screen.height/2 + 20 then
  lives -= 1
  apples.remove(i)
  if lives <= 0 then gameOver = true .
.

. .

func draw() -- background screen.fillRect(0,0,screen.width,screen.height,"#0B3B17")

-- ground screen.fillRect(0, screen.height/2 - 10, screen.width, 20, "#5C3A21")

-- game over if gameOver then screen.setAlpha(0.6) screen.fillRect(0,0,screen.width,screen.height,"#000000") screen.setAlpha(1) screen.drawText("GAME OVER", 0, -20, 36, "#FFFFFF") screen.drawText("Final score: " + score, 0, 20, 20, "#FFFFFF") screen.drawText("Press SPACE to restart", 0, 60, 14, "#CCCCCC") . .

init()

please help me someone

I'm sorry, I cannot read this.

assuming you aren't using java or python or something, functions are

init = function()
end

update = function()
end

otherwise, this format is a bit too messy to read.

please use the triple backticks for all the code and not just the snippet
