Hi, everyone. I made a very simplistic scene manager for you all to use, its somewhat compressed as well. here's an example:

Basically, this scene manager allows you to create init, update and draw for each scene (as well as anything else you want to cook up, of course).

HOW TO USE
to make a new scene, use the command 'nscn' inside of your init function. for example: nscn({init=function() end, update=function() end, draw=function() end})

to grab the current scene thats running so you can modify it or its variables, you can simply create a local variable called 'self'.

local this=scn['self']()

I am interested in the future making a game (not even sure if it would be in Unity, Game Maker, Godot, or something else) and having some dusty arcade cabinet that you find - and it has a Pico-8 arcade game on it!

I am wondering how feasible it is for the Pico-8 game to be embedded and how well the game canvas could be moved around and positioned, incorporated into the game, to look like it's in a cabinet, etc., or if it's even possible at all.

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.

Not sure if this is expected behavior, but it seems that if a monster is a room goal, setting the "infinite death" flag will not respawn them when you re-enter the room.

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.

Modified previous work to add a centroid bar to spiral galaxies.

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.

Instructions

• Use arrow keys to move.
• Press X to switch heroes.
• Bump enemies to attack.
• Stand on two colored squares to ascend, creating a totem from the third square.
• Stand on a green or blue totem to give the other hero an ability:
  • Shoot (green) hits enemies at range.
  • Jump (blue) lets you jump onto enemies and over walls.
• Step on a red totem to gain health.
• Step on an orange totem gain gold.
• Red and orange totems are refilled when an enemy steps on them.
• Ascend to the surface to win.

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

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 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 :)
