Found on windows 0.2.0I
If you select text in the console window and then execute a printh call, PICO-8 hangs seemingly indefinitely

I'm working on a raycaster, and I'm stuck on trying to make billboard sprites; I think that it would be a waste to not at least show off what I had, so here's a little demoey thing.

Can you find all 4 hidden orbs?

Vector math for PICO-8!

Have you ever been looking at your code and been like:
"Hmm, i sure do add two numbers to another set of two numbers a lot," then do i have the solution for you!
At the low low price of like 400 tokens, PICO-8 vector math can be yours!
I originally made this to streamline a platformer I may or may not ever finish, but I realized that other people might want this, flagrant waste of tokens or not.

Features!

The code

There are two versions of the whole program. One handles errors more gracefully, while the other has a smaller token footprint

Required functions:

The metatable depends heavily on these two functions

function vec2(x,y)
 if (not y) y=x
 return setmetatable({x=x,y=y},vec2mt)
end

function vecargs(a,b)
if(type(a)=="number")a,b=b,a
 if type(b)=="number" then
  return {a,vec2(b)}
 elseif getmetatable(b)==vec2mt then
  return {a,b}
 end
end

Fault tolerant metatable

vec2mt={
 __index={x=0,y=0},
 __newindex=function (tble, k, v)
  if k=='x' or k=='y' then
   rawset(tble,k,v)                      
  else
   printh("bad key")
  end
 end,
 __unm = function(tble)
  return vec2(-tble.x,-tble.y)
 end,
 __add = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return vec2(a.x+b.x,a.y+b.y)
 end,
 __mul = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return vec2(a.x*b.x,a.y*b.y)
 end,
 __div = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return vec2(a.x/b.x,a.y/b.y)
 end,
 __sub = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return a+(-b)
 end,
 __pow = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return vec2(a.x^b.x,a.y^b.y)
 end,
 __concat = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return a.x*b.x+a.y*b.y --15
 end,
}

Fault intolerant metatable

vec2mt={
 __unm = function(tble)
  return vec2(-tble.x,-tble.y)
 end,
 __add = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return vec2(a.x+b.x,a.y+b.y)
 end,
 __mul = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return vec2(a.x*b.x,a.y*b.y)
 end,
 __div = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return vec2(a.x/b.x,a.y/b.y)
 end,
 __sub = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return a+(-b)
 end,
 __pow = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return vec2(a.x^b.x,a.y^b.y)
 end,
 __concat = function(a,b)
  local c=vecargs(a,b) a,b=c[1],c[2]
  return a.x*b.x+a.y*b.y --15
end,
}

Normalize function

function norm(vec)
 local power=vec^2
 return vec/sqrt(power.x+power.y)
end

wow karel is an intro-duction to programming that ueses phive whole instructions.
karel can move(), which makes it go forewarde
karel can turnleft() whchic should be obvious
karel may dropchip() thath puts a chip on the ground?
karel can takechip() and that picks up any chips that are on the same tile as it
karel is capable of checkchip() whitch returns the chipcode of the chip its on

okay if you want human redable instruction go to this link

How to play

This is you:

	[0x0]

Move with the directions, and start digesting with [O]
Moving and digesting take up energy, and if you run out of energy, you take massive damage to the health meter

Enemies

Viruses

	[0x0]

These simply drift across the screen, and deal damage if they go off of it.
Touch them while digesting to defeat them

Green Bacteria

	[0x0]

These spawn where you see this symbol:

	[0x0]

They slowly drift away from you.

Yellow Bacteria

	[0x0]

They have a short healthbar that you have to deplete, but are otherwise just like viruses.

Allergens

	[0x0]

Drift across the screen and hurt you if you try to digest them

Powerups

Multiplier
Multiplies your score by 10

Red and white pill (antibiotic)
Prevents both kinds of bacteria from spawning

Yellow bottle (allergy pen)
Allergens will not hurt you

Beige thing (platelet)
Halves spawn rate of all enemies

Green arrows (abstract green arrows)
Makes you accelerate faster
