So i was trying to make an ASCII style procedural runner with a death wall that constantly approaches and enemies to dodge and spike traps to avoid. Im kinda stuck and am getting an error on line 29. Any ideas?

-- ASCII RUN

-- Constants
player = {x=20, y=64, vy=0, on_ground=false, sprite='@'}
ground_y = 96
gravity = 0.3
jump_power = -2.5
death_wall_x = 0
speed = 1.5
score = 0
level = {}

define_tiles = {
[' '] = {solid=false}, -- Empty space
['#'] = {solid=true}, -- Ground
['^'] = {solid=true, deadly=true}, -- Spikes
['E'] = {solid=true, deadly=true} -- Enemy
}

-- Generate procedural level chunks
function generate_chunk()
local chunk = {}
for i=1,16 do
local tile = ' '
if i > 12 then
tile = '#' -- Ground
elseif i == 12 and math.random(1, 5) == 1 then
tile = '^' -- Spikes
elseif i == 11 and math.random(1, 10) == 1 then
tile = 'E' -- Enemy
end
add(chunk, tile)
end
return chunk
end

function init_level()
for i=1,32 do
add(level, generate_chunk())
end
end

init_level()

function update_player()
-- Gravity
player.vy += gravity
player.y += player.vy

-- Collision with ground
if player.y > ground_y then
    player.y = ground_y
    player.vy = 0
    player.on_ground = true
else
    player.on_ground = false
end

-- Jumping
if btnp(4) and player.on_ground then
    player.vy = jump_power
end

end

function update_level()
-- Scroll the level left
death_wall_x += speed
score += 1

-- Remove old chunks and add new ones
if #level > 0 and death_wall_x % 8 == 0 then
    deli(level, 1)
    add(level, generate_chunk())
end

end

function check_collision()
local px = 2 -- Player's x position in array (adjusted for indexing)
local py = flr((player.y - 64) / 8) + 1
if level

an interactive drawing tool to create and explore unpredictably chaotic black-and-white graphics

tool drawing generetive art graphics chaos pen unpredictable interactive

Result of mini gamejam with my 6 year old kid.

This cart has already had its ID written to the bottom of the MAP (x:0-127, y:32-64).
When you run it, the following processes are performed.

• Change the drawing target to the sprite sheet
• Call rectfill() with color 0 on the bottom of the sprite sheet (shared with the bottom of the MAP)
• Change the drawing target to the screen
• Draw the bottom of the MAP

The screen should turn completely black as expected, but the MAP continues to draw what it was before it was updated.

Finally, it calls cstore() to exit, and when you run it again, it will update to a completely black screen.

Murdercrab! A 5 stage caravan thing that I'm currently tweaking. There is a bug or two but should be able to make it all the way through to the TLB. There are lots of knobs under the hood to mess with level scaling and balance, let me know if you come up with a good balance. I'm still dinking around with the bullet patterns as I'm not really happy with them atm.

Ripped all the music from pico tunes, so all credit goes to gruber for music

Update 1
I found the fun
Most of the balancing and patterns are in a better state, although the game is too easy.
The core gameplay loop is locked for the most part. I'm still chasing a couple of errors and bugs, especially with the hi score.

Next step is to split it in to two carts and polish

Update 2
did the split and a little polishing. High scores still broken.

Hmm, ill have to figure this out later, it's not loading right in the BBS. If you download both carts you should be able to play it fine. Start with the menu cart

shooter shmup stg caravan arcade cartridge

Basically remade the original Super Mario Brothers for the NES from 1985.
The game is still work in progress, so Question Blocks don't work yet.
More will be added soon!

I've been working on a little side project while making my first Pico-8 game.
It's a cart with some art in it.
I've recently tried adding in a zoom feature for the smaller art.
But for some reason it won't change screens.
Any help would be great.

100% real ai

I dont thing I need to explain, I just wanted to learn more about coroutines.
Have fun :)

Well, this is no pong.

This game was made for the NOKIA 3310 JAM 6, in like 2 days or so.
The entire game was made in only like 823 compressed bytes! which is like a 1/20 of the original donkey kong game :O
Check out the original jam post Nokia Jam / Nopong

READ THE CONTROLS!

• Left and right to move
• DOWN TO GAIN MOMENTUM DOWNWARTS
• you have to keep your height to break the blocks

Gain points by breaking blocks,
when you break all blocks you have to die ONCE and then go on the platform again,

I recommend playing it with sound, have fun :)

Thanks Nick!

You're a goon on the loose, but the fuzz are hot on your tail!
Survive for as long as possible and collect as much loot as you can before you're done in.
