its gonna be a race

update:I added more sattelites and a cow (very productive I know).
Still thinking about the gameplay, I think I am going to make them be able to bump into eachother and collide with astroids and maybe sattelites aswell. and when they eventually get to the moon. maybe do a moonlander mini-game or something.

Hi all,

I'm writing a short graphical text adventure for the PICO-8, and a few weeks ago I determined that I needed a vector graphics editor capable of outputting PICO-8 code. I've created a web app called GMagic that lets you make vector drawings on a canvas, then export Lua functions for drawing them. I also provide the functions for drawing polygons and polylines:

ptstr() (needed for the functions):

 
function ptstr(s)
	local data={}
	local wip=''
	for i=1,#s do
		r=sub(s,i,i)
		if(r==',') then
			add(data,wip+0)
			wip=''
		else
			wip=wip..r
		end
	end
	add(data,wip+0)
	return data
end

Polygon:

 
function poly(r,c,p)
	local t=ptstr(r)
	--based off alienryderflex.com/polygon_fill
	--t=table x1,y1,x2,y2...
	--c=colors (hex)
	--p=pattern
	local pc=#t/2
	local px={}
	local py={}
	local my=127--miny
	local xy=0  --maxy
	--split out xy lookups
	for i=1,#t-1,2 do
		add(px,t[i])
		add(py,t[i+1])
		if(t[i+1]<my) my=t[i+1]
		if(t[i+1]>xy) xy=t[i+1]
		if(i<#t-2) then
			if(p) fillp(p)
			line(t[i],t[i+1],t[i+2],t[i+3],c)
			fillp()
			--yield()
		end
	end
	--scan down the screen
	for y=my,xy do
		local nx={}
		--build a list of nodes
 	local n=0
 	local j=pc
 	for i=1,pc do
 		if((py[i]<y and py[j]>=y)
 			or(py[j]<y and py[i]>=y)) then
 			add(nx,(px[i]+(y-py[i])/(py[j]-py[i])*(px[j]-px[i])))
 		end
 		j=i
 	end
 	--bubblesort nodes
 	local k=1
 	while(k<#nx) do
 		if(nx[k]>nx[k+1]) then
 			nx[k],nx[k+1]=nx[k+1],nx[k]
 			if(k>1) then
 				k-=1
 			end
 		else
 			k+=1
 		end
 	end
 	--fill the pixels
 	for l=1,#nx-1,2 do
 		local d=nx[l]
 		local e=nx[l+1]
 		if(d>=127) break
 		if(e>0) then
 			if(d<0) d=0
 			if(e>127) e=127
 			if(p) fillp(p)
 			line(d,y,e,y,c)
 			fillp()
 		end
 	end
 end
 --yield()
end

The game is a work in progress, but is mechanically complete. Just adding levels and polish at this point.

EDIT: I've got 6 levels so far. I'm going for maybe 10-15, and then I want to add some more SFX and music.

This is a work in progress randomly generated marble game. I have to shout out Eggnog, who made the excellent game PicoPutt. You should go play that, this game is only possible because of his excellent collision methods, and it's not nearly as good.

It's an implementation in pico-8 of the famous puzzle game,
with one of the most beloved rulesets amongst the game's enthusiasts.

WIP.

Today I am starting a new tutorial series on how to make a Roguelike in Pico-8. New episodes will be released throughout February. Hopefully, we will be done before the 7-Day Roguelike Challenge 2019 begins. The series is designed to give you the skills and tools to participate in that challenge.

If you have any questions of feedback you can post them in this thread.

Here is the full playlist

Here are the videos:

#2 - Basic Movement

A difficult platforming game with a gardening/Splatoon-like twist. Made by Charlie Tran

This is one of my first games, and my longest to date. Please let me know what you think, thanks!

A tweetcart I made to teach myself what sin() and cos() actually do. I never took trigonometry.

A demake of my game Patrick's Cyberpunk Challenge for the TweetTweetJam.

The object of the game is to move Patrick the Leprechaun around the board and remove all 28 squares. Squares with special symbols will remove extra squares:

Move Patrick to a square using the arrow keys. Note that you can (and sometimes must) move diagonally by pressing two arrow keys simultaneously.

Puzzles might be impossible to solve, and the game doesn't recognize if you win or lose. If the screen is empty except for Patrick, you win! If you have no legal moves, you lose and must restart the game manually.

Not a big problem, but probably easy to fix.

If you're in the sprite editor and press Alt+Left to go to the code editor, the cursor will move one space to the left.

The same happens if you're in the music editor and press Alt+Right; the cursor will move to the right.

Here's a strange bug I found. If you write something like this in the code editor:

 
rectfill(0,0,5,5)

and you search for 0 with CTRL+F, it will highlight the first 0. If you then press CTRL+G, however, it will fail to find the second one. The same goes for the 5.

From my testing, this seems to only happen with every other occurence. If you search for 0 here:

 
rectfill(0,0,0,0)

then CTRL+G will only highlight the first and the third argument.

I've only had it happen with function arguments, and only with single-character arguments; single-letter variable names also have this problem. Putting a space after the commas also makes it behave properly.

It's a bit of a problem when writing tweetcarts where you have little whitespace, short variable names, and want to find variables or number literals to replace while optimizing :)

WIP version of a little roguelike I'm working on.
Sprites are based on Scroll-o-Sprites by Quale-Art.

You are THE BOY and you have entered the DIRE DUNGEON in search of treasure and glory!

Currently, v0.1 only features character and camera movement.

This was totally a bug but I decided to add Back In Black and some beers.

Enjoy !
