Teaching myself some basics by revisiting a TV classic. This is from a while back and I have a better way of animating sprites now. I need to learn how to do wall collisions still. Advice is welcome.

An action-packed top-down racer - like a combination of Micro Machines and Mario Kart.
Start off at 50cc and work your way up to the high-speed 150cc races.
Use powerups to blast through your rivals and knock them into last.
19 different races to complete - including special icy tracks.

Moving game pieces using atan2().
I check to see if the position (px,py)
has reached the target (tx,ty) by
absolute values of positions minus targets.
If they havent reached the destination I increment
by the dx I got from the atan2() calculation.
This works as it is. But I cannot actually control the speed.
If I want it to go faster, say speed 8, there are certain
situations where condition if abs(px-tx)<3 and abs(py-ty)<3 will never
be met and piece will just go forever. And I cant fine tune the <3 either
because sometimes the math just wont allow it.
How do I write code or think about this to move my sprite so I can actually control
the speed and/or accuracy?
Must be able to move any direction at any angle.
Thank you.
speed=5 px,py=getxy(location) tx,ty=getxy(destination) local angle=atan2(ty-py,tx-px) dx=sin(angle)*speed dy=cos(angle)*speed --PROBLEM HERE function _update_move() if abs(px-tx)<3 and abs(py-ty)<3 then --AND PROBLEM HERE --ARRIVED AT LOCATION else px+=dx py+=dy end end |

Hello this is my first game, it's for a school project for fourth grade, and I really really worked hard on this with some help from my dad, my sister (for the art) and Youtube tutorials.
Please give it a try, I'd like some feedback to improve. I hope you enjoy it!!

Updated to remove annoying sound effects. Next version will make them a little more subtle.

A Cartridge for a public presentation on Pico-8
A few months ago I was preparing a talk on pico-8 for our local Makespace.
I was going to use PowerPoint. But I thought it would be fun to make my "powerpoint"
presentation as a Pico-8 cartridge. I could then use the same Cartridge as an example
of coding, sprites, and sounds editing.
You are encouraged to take it and modify it as you want.
The text all lives on tab 2.
The notes for running the presentation are on tab 4. Copy and paste it onto the
a blank editor to see some of the directions to run such a presentation.

Before the presentation
- prepare handouts such as pico-8 cheat sheets

PicoTowns is a town building game inspired by the boardgame Tiny Towns (https://boardgamegeek.com/boardgame/265736/tiny-towns) and the game Tiny Islands (https://dr-d-king.itch.io/tiny-islands).
Build a town out of buildings that arrive in the form of tetris style pieces. Each turn you have a choice from a big or a small piece to add to your town. You have 15 turns to arrange them in a way to try and get the highest score possible!
Daily Challenge mode will give everyone the same sequence of pieces, so you can compete with friends for the highest score each day. (On some platforms, you can click the micromap at the end of the game to copy your score to the clipboard)
In game help is available (click on ?) - this will explain scoring with some diagrams.

I made a simple paint package, Whiteboard, for taking notes.
It uses the mouse by default, but you can choose to instead use the D-pad + X in the pause menu.
Controls
O: Switch between marker and Eraser
X (gamepad mode)/left-click (mouse mode): Use tool
D-pad (gamepad mode)/moving mouse (mouse mode): Move cursor

In "Select Stages" choose which stages are active, hit the "Randomize" button on the main screen and get a random level!
This is a stage randomizer I built for fun. I experimented with coding all the UI elements myself, like buttons and checkboxes.
More info in the "About" section!

A co-worker was curious to use my interactive fiction player, Status Line. He's using "nixos" and he rebuilds large parts of it from source, from scratch, every time before launching into the operating system. At any rate, his setup can't run the Linux binary because his doesn't have some set of dynamic libraries that Pico-8 is expecting. Steam apparently has a similar issue which is fixed by something called "steam-run" which kind of tricks Steam into seeing a "typical" Linux environment. That method is not working for Pico-8 exported binaries, it seems.
Is there a way to export a 100% static-linked binary?

Just a simple space shoot 'em up.
Shoot enemy spaceships and dodge meteors.

Update: Bug fixes
Here's a little line drawing routine I've used for Whiplash Taxi and some other work-in-progress carts.
I wanted to package it up like a drop in tline replacement.
It's equivalent to regular tline, but instead of drawing each tile it uses it to lookup a higher resolution 8x8 tile region and draws that instead. The result is a map with 8 times the detail (or 8 times the size, depending on how you look at it).
The demo is a simple go-cart example. You can press X to toggle between the new routine and the regular tline function.
The actual routine is in tab 1 and consumes 547 tokens.
To use it, you first create some 8x8 "textures" at the top left of your map region:

There are many ways to loop over an array-style table. For example:
local tab = {10,20,30,40}
-- method 1
local calc1 = 0
for i,elem in ipairs(tab) do
calc1 += i*elem
end
-- method 2
local calc2 = 0
for i=1,#tab do
local elem = tab[i]
calc2 += i*elem
end |
Which way is fastest? Well it often doesn't matter, since the work inside the loop usually far outweighs the cost of the loop itself. Or tokens might matter more to you than speed. But in some situations you want your code to be as fast as possible, and that means minimizing the overhead from the loop itself.
Setup
So, which way of looping is fastest? Here are the methods we'll compare:
function for_i(tab) for i=1,#tab do local x=tab[i] -- do some work end end function for_all(tab) for x in all(tab) do -- do some work end end function for_ipairs(tab) for i,x in ipairs(tab) do -- do some work [ [size=16][color=#ffaabb] [ Continue Reading.. ] [/color][/size] ](/bbs/?pid=164729#p) |

Controls:
- Don't move to shoot.
- PRESS X TO USE A POWER UP
How to play:
- Shoot ships to earn coins in each run.
- Unlock the four ships with coins.
- Get cooler weapons.
- Have fun.
Running a mission:
- Avoid the enemy ships.
- Stop moving to shoot.

--for the best experience, play with headphones on.
--ABOUT--
Goom is a small, and yet challenging and fun demake of Doom, a popular fps.
you will run around a small room, defeating waves of enemies until you reach the final boss.
you can shoot using your mouse and run around the map with either the arrow keys, or esdf.
watch your ammo too, as you only have a little bit. however, ammo is restored each round. not your
lives though, so watch out for bullets, and dont get to close to the enemies!
and dont worry, your highscore will be saved!
--CREDITS--
this game was made by Dominic!
