Pico-8 Injects

If you dont know what an "inject" is, ill explain it here.

An inject is a script or program that you append (add) to the end of another program to serve a function. good examples of an inject are code snippets you add to the end of a cartridge to alter things in real time or gain extra functions. RTCP is a great example of a code inject (code below). you simply just add the inject in a new code tab, and it automatically does its set function(s) without having to modify the source code.

Here are a few injects i have created

RTCP

--[[ rtc-p+ ]]--
--portable rtc made by antibrain
cf,clvl,ct=150,100,0
if _init!=nil then _init()end
function rtc()
if cf<0then cf=0elseif clvl<0then clvl=0end
menuitem(1,"corrupt spd:"..cf,function(b) icf(b) end)
menuitem(2,"corrupt lvl:"..clvl, function(b) iclvl(b) end)
menuitem(3,"nxt crpt in:"..-(ct-cf))
ct+=1
if ct>=cf then ct=0
for i=1,clvl do
poke(abs(rnd(-1)),rnd(-1))
end end end
function icf(b)
if(b&2>0)then cf+=10 rtc()end
if(b&1>0)then cf-=10 rtc()end 
return true end
function iclvl(b)
if(b&2>0)then clvl+=10 rtc()end
if(b&1>0)then clvl-=10 rtc()end 
return true end
while true do 
rtc() if _update!=nil then _update()
elseif _update60!=nil then _update60()
end if _draw!=nil then _draw() end
flip()
--the below loop can be removed if you are short on tokens.
if (_update==nil or _update60==nil) and _draw==nil then
?"no update or draw loops found!"
?"for carts that dont use"
?"game loops, load #rtcp and"
?"use that instead."
?" "
?"if loaded off bbs, please"
?"use a pico-8 editor to use this."
stop()end end

A mod of MarkGamed7794's Picoris that allows you to create your own pieces. This is my first project with pico 8, a Tetris game where you can make your own pieces is something I've wanted to play for a while and very proud how it came out. I added a lot of original features and modes as well as many from Picoris 2.

I've had a lot of fun playing and creating this and problem solving to fit a lot in the cartridge, hope you enjoy!

Story

	[8x8]

The story about Mox unfolds in a small canyon enclave, where he's stuck and can't escape. The canyon has been overrun with bandits and other mysterious creatures. There are trains passing multiple times every day, but they never seem to stop in the small town, maybe he can find a clue? (wip)

Hello !!

I'm learning to code, but I quickly find myself getting sidetracked by trying to implement things I haven't seen in the games I've played yet, and ultimately, I end up wasting a lot of time starting over.

I would like to hear your thoughts on Pico-8, what has helped you progress the most? Was it blind development like I'm attempting without any prior experience? Did you follow tutorials or take courses? Did you look at the code of a game you like to try to understand and learn from it?

Specifically, if you were to start Pico-8 programming today with the hindsight you have now, how would you begin?

Thanks in advance.

I'm just getting into PICO-8, so this post is largely just me saying Hello World :)

Here's what I have to show (in the best way) for the past few days of learning how to develop in PICO-8 - tutorials have been super useful and I love what I've seen of the community so far!

____ SPACE ROGUE! ____

Embark on a mission to destroy the enemy aliens!!!!!

Upgrade your ships weapons as you power up in this Space Invader/Roguelite mash-up!

How many enemies can you defeat before re-upgrading your ship?

UPDATE 1.3:

The new update for Space Rogue! adds more core mechanics to make the game be the roguelite that it is! This update adds replay value and provides a foundation for future upgrades & enemies!!!

-- NEW post run shop upgrades!!! Continue your run after your death with an upgraded ship!

• Triple shot!: Fire three bullets at once!
• Upgrade your maximum shield capacity!
• Unlock a power-up that will re-fill your shields to max level. Handy for long runs!

-- Balanced enemy spawns and added a NEW enemy type!!! (this one shoots back!)
-- New sprite for the ships bullets. Adds little more imagination than a yellow brick :)
-- New soundtrack!!! (This one has a bass line! :O)

Also changed up the coding for the way the game handles enemy collision, weapon collision, upgrade logic etc... This will make adding more upgrades & enemies in the future less of a task!

Have fun!

this game has a nice peel..

controls:

• Up and Down = move the knife/stick
• hold c = move faster vertically

Lore:

After years of practice this now is the final exam, bob has to make it. After failing school, work and college, his only choice was clear. To eat potatoes, that would make him grow bigger and stronger, or so he thought. Life is hard, it was a constant pressure on him, he could not rest a minute. that's how busy he was, peeling potatoes. The problem was there, bob didn't have a proper peeler, or a knife. He had to use a stick (don't ask how its possible). The potatoes were weird as well, there were only huge ones. In fact, he was standing on the potatoes. But after years of training and hard work, it finally came to him. He knew the perfect job for him. So he applied for a job at peelstation, you know, the place where they make potato games. But here comes the twist. His parents were actually giraffes. But to him, it didn't matter, his goal is clear. He needs to get a 100% on this test, otherwise he isn't the potato master. Just imagine the consecutive, it would be eternal shame. This here is the moment, can YOU make it ?

Rules

In SameGame, you need to remove groups of like-coloured tiles from a randomly-generated board. Clearing larger groups of tiles will award you more points. You cannot remove individual tiles.
Tiles will fall downwards if the tiles below them have been removed. If a column is cleared completely, all of the tiles to the right of it will be shifted left to close the gap.

Modes

Both modes start with the grid full of random tiles.

• Normal Mode
  In Normal Mode, the goal is to remove as many tiles from the board as possible. The score and move counters don't really mean much in this mode.
• Endless Mode

This is my entry for the 2024 FishFest Game Jam. Help Kalea the shark get her dinner. But beware! Barrels of gunpowder, harpoons, and a guy named Quint are out to hurt you. Try to string fish bites together for more points.

How to play

Hold Z or X and release to jump out of the water and eat fish.
Avoid barrels, harpoons and oxygen tanks!
