This cart outlines a fairly simple way in which diagonal vectors can be normalized, to avoid super-fast diagonal movement. On tab 0, you can check out the normalization code, and an example of where you should drop it in your code to make it work!
Feel free to use this function in your code, or to revise the math to make a more efficient system! The movement is a little jittery, so there's definitely room for improvement!
Also ... Vector the Skateboarding Duck might feature in future games. We'll see!

You are the tomato worm and you are very hungry for tomatoes. Clear mind-bending puzzle levels of all tomatoes by eating them while making sure you don't get stuck in corners with your growing body.
Controls:
arrow-keys/d-pad: move the tomato worm on the grid
x: go to next level after clearing the current one
z: restart current level
Update 1.0:
- 65 levels
- more gameplay elements including non-ripe tomatoes

Guide your character on a journey through dungeons inhabited by perilous adversaries. Solve puzzles and discover secrets to get your hands on that special kind of loot.
The game pays homage to the old isometric classics like Cadaver, Hero Quest, Darkmere etc.
-- WORK IN PROGRESS --
TO-DO:
- Add monsters, with basic AI (wander/patrol and attack on sight)
- Combat and damage formulas
- If token/compressed space allows it I'll add the map feature, else it'll be kicked to the curb.
- Player character animations (idle, walk, melee, cast spell, die)
- Add some more props/decor if spritesheet allows it
- Optimize
- Optimize
- Optimize
- ...Optimize!

Description
Enter a cursed tower where the world has come alive and grows with every touch! Reach the top of the tower to attain the chalice and break the curse!
Instructions
- Use the arrow keys to move.

Itty bitty baby update! I want to keep this weekly to make sure it gets finished before the new year:
*A small bit more structure. And ... secret object 'C' has been added.
I said I'd upload something to do with this within the week
so here you go:
Z - Jump
X - Shoot
S - Toggle palette
A little of the framework is set. I'm going to clean things up a bit and add more features next week.
You can use the code/art here for whatever you want. The goal is to make something people can use/learn from. Fair warning that the codebase isn't great atm; expect improvements next update. The lil robot suit thing is a character I use in stuff, but you can have her cameo in a game or whatever. It's not a big deal.
Feel free to request features or leave feedback here.

Hi everyone! I know something about coding (very basics stuff) and I'm new to PICO-8.
I'm doing some tests, one of this consist in highlighting an object when the user switch between two objects.
I need some kind of switch, like: when you press 4 the first time highlight X, the second time Y, the following times switch to the other.
This is the code, sorry for bad english:
rect1_x1=5 rect1_y1=120 rect1_x2=20 rect1_y2=110 rect2_x1=5 rect2_y1=5 rect2_x2=20 rect2_y2=15 sex1=-1 sey1=-1 sex2=-1 sey2=-1 function _init() cls() end function _update() cls() if btn(4) then sex1=rect2_x1-1 sey1=rect2_y1-1 sex2=rect2_x2+1 sey2=rect2_y2+1 elseif btn(4) then sex1=rect1_x1-1 sey1=rect1_y1-1 sex2=rect1_x2+1 sey2=rect1_y2+1 else end end function _draw() --background----------- rectfill(0,0,127,127,1) --select--------------- rectfill(sex1,sey1, sex2,sey2,10) --1-------------------- rectfill(rect1_x1,rect1_y1, rect1_x2,rect1_y2,8) --2-------------------- rectfill(rect2_x1,rect2_y1, rect2_x2,rect2_y2,8) end |

I've been looking for a coding project to fiddle with on the go. Discovered that as a Voxotron owner I also own Pico-8, which was a generous bonus (ありがとうございます！）I use a Surface Pro 2017, and the lightweight nature of Pico-8 is perfect for this tablet size with the on-screen keyboard. However there are a few points that need addressing:
- On-screen keyboard arrows don't work. (hoping someone can confirm? Makes the editor a drag to use)
- Headphones are ignored. All other apps play sound through headphones but Pico-8 forces everything through the Surface Pro speaker. See below.
- Touch to interact with the editor window requires a double-tap where a single mouse click works. Basically the touch input just doesn't feel natural, as when changing toolsets or positioning the text editing cursor.
Hoping that there are API abstractions on Windows platform that can be adopted for "get touch support for free!" (he said, understanding that nothing is ever so simple)
東京に住んでいるので、そろそろピコピコカフェに行くつもりです！
素晴らしいアプリを作って大変ありがたいです。

Hey,
I finally managed to tie all the loose ends together in my Outrun-esque racer. There's only one route, but the controls have some nuance which should make for healthy competition.
I know very little about 3D and projection and stuff, so most of the tech is from this excellent article:
https://codeincomplete.com/posts/javascript-racer/
Have fun! And what's your best time?

I noticed that if there is a file named "splash.png" in PICO-8’s directory, it will be displayed at launch before the boot sequence. This also works with cartridges exported as binary.

Hi all,
I finally found the time to tie together all the loose ends in my Outrun-esqe racer. It is just a single level, but there's some nuances in the controls which should make for health competition!
What's your best time?

Just testing out some sprite art that I made. Don't look directly at the code without personal protective equipment.

EDITED 2/14/2020
I came up with several functions that I think would go good in pico8 and would reduce file size for larger games
--math
function ldx(d,l) --stands for lengthdirx
return cos(d)* l or 1
end |
function ldy(d,l) --stands for lengthdiry
return sin(d)* l or 1
end |
function ptl(x1,y1,x2,y2) --stands for point length
return sqrt(((y2-y1)^2)+((x2-x1)^2))
end |
function ptd(x1,y1,x2,y2) --stands for point direction
return atan2(y2-y1,x2-x1)
end |
function wrp(v,l,h) -- stands for wrap
local o=v
while(o < l) o += (h-l)
while(o > h) o -= (h-l)
return o
end |
function rng(v, l1, h1, l2, h2) -- stands for range
return l2 + (v - l1) * (h2 - l2) / (h1 - l1)
end |
--vectors
function vec(vx,vy) --stands vector local m= [ [size=16][color=#ffaabb] [ Continue Reading.. ] [/color][/size] ](/bbs/?pid=55218#p) |

I'm going to call this the beta version, I'll show it at the boston indies showcase tonight and hopefully catch whatever bugs might be left.
Most certainly the last iteration before release.

how to create smoth gridmovement for player?so he smoothly moved to the side of the grid cell?

can someone tell me why my objs.add() function isn't working?
its supposed to let the user pass in a table or object struct and create and store a instance of it.
however it seems to overwrite the instances with the most recent call so they always get created with the last call's paramaters.

Inspired by watching tutorials from Bridgs, MBoffin and Gruber. Scenery collision is a bit hit and miss (lol), but I'm scratching an itch with it right now. This one is 2-player only, sorry - but my goal is a bigger map and a decent single-player mode. Oh, and the next production will have a little more polish to it (including a proper 'death' animation ha ha).... and I'll learn about writing 'optimal' Lua code
Objective
Player 1 and Player 2 get to drive around one of 4 maps, blasting each other. Shots can ricochet off the mountains but will travel over water. The harder difficulty adjusts the rate of reload and your speed in relation to shots.
Cheers
Robsoft
