I make games and pixel art and love PICO-8!


PixelCod

In my opinion, taking snippets of code/music/gfx from Pico-8 games with permission from the author to put in your own games is great as it helps build the community up and help beginners.

What I don't like is when people keep on taking other peoples games, changing some sprites, then re-posting the game as a "Hack". All this does to the community is make people appreciate the author of the "Edit" (that spent 10 minutes on the game) rather than the original creator that spent hours of their life creating these games.

On top of this, it fills up the BBS with duplicate games (that a worse versions than the original) rather than new, interesting content.

If you're going to make a "Hack" then at least make it a worth while change and credit the author with A LINK TO THE ORIGINAL GAME.

However, this is just my own opinion so feel free to comment your thoughts and ideas on the subject below.

Hello Pico-8'ers!

I've been wanting to be able to make a game in which you explore a large game world that is bigger than the available map space in Pico-8 for some time now but I can't see an easy way of doing this. I've seen people using bits of the sprite space but I'm still not sure how they achieve this.

I'd like to be able to have a giant game world similar in size to that of 'Duck Duck on the Loose'

If anyone knows of ways to do this i'd love to here your ideas!

After a long time without any updates I have decided to post version 0.5 of the game in its current, un-finished state. There is no goal as such apart from mine gold and build some cool looking space stations. Since version 0.4 many changes have been made such as adding a title screen, fixing some sound issues, improving sprite work, adding some new building blocks and many other improvements.

This is an unfinished update and game overall that will most likely never be finished but I hope you enjoy what is here now. I think that it is for the best for me to move onto new ideas and projects rather than get stuck on the same project for months on end.

Hey all, I was just wondering if there is a way to run Pico-8 games on the web (using HTML) or on a desktop at native resolution; One pixel on Pico-8 corresponds to one pixel on my monitor to get a tiny Pico-8 game window?

Any body know if this is possible?

NOTE: This is a guide to my menu system that I have used in the example cartridge however contains mostly general tips that you can adapt to your own needs.

This is a simple guide for my Menu System that also shows off how to do simple 2-colour palette swapping. Anyone is free to build upon and implement this system into their own games they make.

If there are any questions or queries, feel free to leave a comment and I'll try to reply as soon as possible. Here are some guides suitable for beginners to help explain how to use it.

Guides

How To Add More Options:


To add, change, or remove options from the menu you have to edit the m.options variable:

 
M.OPTIONS={"OPTION 1", "OPTION 2", "OPTION 3"}

This will display each item as a separate option in the menu. To add more options simply add more items to the array separated by commas.

How To Select Options:


To make something happen when you select an option we need to check for a button press. We can do something like this:

 
IF BTNP(4) AND --If the button 'z' is pressed
MENU_TIMER>1 THEN
  INIT_SETTINGS() --Do something
END

We set MENU_TIMER to 0 in any init() functions to do with the menu (e.g. INIT_MENU() or INIT_SETTINGS() ) and then increment it by 1 in the UPDATE_MENU() function. We check that MENU_TIMER is bigger than 1 to ensure that we don't select more than one option at a time.

Instead of calling INIT_SETTINGS() here you could make it do something else, for example, start the game.

How To Change Palettes:


To be able to change palettes we first need a list of palettes that we can switch to. This can be done like so:

 
--Inside an _init() function

PALS={{7,0},{6,5},{10,8}}

PALS is the variable that will store our palettes (sets of 2 colours). Each item in PALS is another array containing 2 values, a colour 1 and a colour 2. Our first example palette in PALS is {7,0}. Colour 1, represented by 7, is the colour white in PICO-8 and colour 2, represented by 0, is black. By setting our text to draw using colour 1 and the background to draw using colour 2, we can end up with a menu that is white with a black background.

To do this we need to create some variables to store the active colour 1 and colour 2 that we want to use:

 
--Inside an _update() function

COL1=PALS[PALNUM][1]
COL2=PALS[PALNUM][2]

PALNUM refers to the number of the palette you wish to use. For example, if PALS={{7,0},{6,5},{10,8}} then PALS[2] would give us the second index, which in this case is palette {6,5}. PALNUM can be a hard coded palette number or can be dynamically changed in-game by selecting a menu option as I have done in the example cartridge.

For COL1 we firstly referenced PALS, then the palette to look for inside PALS (using PALNUM) and then we searched for '1'. The number 1 here means 'the first item in PALS[PALNUM]' or 'item 1 in PALS[PALNUM]' which will give us the first value of one of our palettes! We can then use this to select the first and second colours of our chosen palette and assign them to COL1 and COL2.

To use our new COL1 and COL2 variables, all we have to do is replace anywhere we have hard coded in a colour with either COL1 or COL2:

 
PRINT("HELLO WORLD",64,64,[b][u]7[/u][/b]) ------> PRINT("HELLO WORLD",64,64,[b][u]COL1[/u][/b])
CLS([b][u]0[/u][/b]) ------> CLS([b][u]COL2[/u][/b])

For changing palettes for sprites, you can draw all of your sprites in black and white and then use PAL(7,COL1) or PAL(0,COL2) before you draw your sprites. This will replace the white on your sprite with COL1 and replace the black on your sprite with COL2. Here's an example using my little octopus sprite:

[16x16]
No use of PAL()

[16x16]
PAL(7,Col1)
PAL(0,COL2)

When doing this, remember to call PAL() with no arguments after drawing the sprites to reset the colors back and avoid coloring issues.

Thanks for checking out my guide! I may end up making some more in the future but we'll see how this one turns out...

Happy Coding!

Update 1.5! - Music, Mines and Mayhem!

I've been working hard lately on some of my current projects and finally got around to updating Space Delivery! This time round I've added in enemy mines that you need to dodge whilst collecting and delivering packages around the map. On top of this, the player can now get a GAME OVER screen when they die and strive to beat that high-score! I've also worked on ironing out lots of bugs and improving the overall graphical fidelity of the game.

Feedback:
As always, community feedback is much appreciated and has a big impact on the final result. Any suggestions, constructive criticism (or just criticism) about the game are more than welcome!

Changelog:
-Added bad music
-Added a deadly space mine enemy
-Added a game over screen
-Added high-score functionality
-Added a black border around text for better readability
-Added a particle system for creating explosions + smoke
-Added SCREENSHAKE
-Added sprite frame animation support
-Added more asteroid islands
-Optimised some functions
-Players now gain 2 health whenever they deliver a package
-Changed the package sprite to a more traditional box
[8x8]

Controls:
Arrow Keys - Move
Z - Land / Take-off

Follow the arrow to collect and deliver packages. Land on the delivery zone to deliver a package.

Update 1.4.1! - Sound!


Just a small update to re-implement sounds into the game. It's interesting how much of a difference it makes with and without sound!

Update 1.4! - Overhaul!

So after another long break from the game whilst developing 'Shuriken Toss', I decided to revisit it and... completely remake it! That's right, completely re-write the game and strip it down to the bare bones and focus this time on the core gameplay mechanics and functions of the game. I felt that I kept wasting too much time before getting bogged down with trying to optimise the game (although it was never optimised!) and adding silly extras such as text systems and palette swapping when there was no core game there yet. This is a good thing, however, as I have learnt a lot from working on this and other projects that has helped to better this game.

Objective:
Your goal is to follow the direction of the objective arrow and collect the delivery orb. You then take it back to the drop off point marked by a:
[8x8]
and land your ship on it by pressing 'Z' ('A' on a controller) in order to score a point. There is currently no win or lose conditions so you can keep scoring to your hearts content!

Future Ideas:
Next I think I will try and add some kind of threat to delivering the orbs like space mines or enemies that keeps the player on their toes. I may also add shooting, however I'm very tempted to keep the protagonist a pacifist as they are only a delivery courier, not a space marine ¯_(ツ)_/¯. Any suggestions would be greatly appreciated ;) .

Feedback:
At the moment I'm very torn with whether to add the fuel system to the game or not as i feel as though it can be more of an inconvenience than a 'main feature'. I would love your feedback and ideas on this and any other aspects of the game, thank you!

Changelog:
-Changed the world size from 3x3 rooms big to 4x4
-Changed maximum fuel capacity
-Changed fuel bar size and position
-Added 'Delivery Orbs' that can be delivered for points
[8x8]

-Added a score to the UI
-Added an objective pointer that points towards the 'Delivery Orb'
-Added a life bar for the player that decreases by one when you run out of fuel
-Added a classic building from the old versions of the game back in because I liked the design
-Removed sounds from the game (temporary)

I hope you enjoy this early version of the game!

Update 1.3! - Fuel, Explosions And Even More Space!


Sorry for not updating for so long (I've been rather busy) but here is my Space game at the moment. It's still pretty bare-bones with no goal however I've been working hard on implementing some new features and had to completely re-write how the world map is stored and used by the game... See the change-log below for a full list of changes. I'll probably add some kind of respawn next after you explode and see if I can get a simple delivery system working. Any suggestions in the comments are welcome as usual!

Future Update Ideas:
My idea for this game is that you'll have to collect and deliver packages from around the map to certain places whilst dodging enemies and making sure you don't run out of fuel on the way! The fuel gauge can represent the players fuel AND also the players health so that your fuel decreases when you get attacked AND when you fly around.

Known Bugs:
-Explosion particles stay on the screen when you change room
-Player sometimes doesn't spin out of control when they run out of fuel

Changelog:
-Changed ship speed and acceleration/deceleration
-Changed the map to now support 3x3 rooms!
-Changed all of the contents of the rooms
-Changed landing/taking off speeds to be faster
-Changed all of the sounds in the game
-Changed the name of the game to 'Space Delivery'
-Changed screen border thickness
-Fixed when the player moves into the next room
-Fixed graphical glitch when changing rooms
-Fixed players minimum landing height
-Added a simple menu system for palette swapping
-Added a title screen for the menu
-Added a fuel system for the ship
-Added particle generator for explosions
-Removed the text system (for now anyway, it was creating clutter)
-Moved the palette swapper into the menu
Update 1.3.1
-Fixed a sound bug

I was wondering how I would go about making some flashing text for a game-over screen that reads "press z to try again". I tried using modulo however when I attempted this it would display the text for one frame and then show (about) 30 empty frames.

Any help on a simple and effective method would be greatly appreciated.

I'm quite new to Pico-8 and video game programming and so started out by making a simple ping pong like game. I can't seem to figure out how to make my ball collide with the side of the paddle however which leads to the ball getting stuck inside the paddle, bouncing up and down, or just passing through the paddle.

Ideally I'd like the ball's x and y velocity to reverse when it hits the sides of the paddle.

Thanks in advance for any help!

'p' is my paddle object
'b' is my ball object
p.w is the paddle width
p.h is the paddle height

 
 --ball wall collision
 if b.x>=128 then b.dx*=-1 end
 if b.x<=0 then b.dx*=-1 end

 --ball paddle collision top
 if b.x>=p.x and b.x<=p.x+p.w and
 flr(b.y)==p.y-b.size then
   b.dy*=-1
 end
