What are the actual steps one must follow to begin scripting in Voxatron?

It was right in the API docs

EXAMPLE (global script)

  1. create a script object, add it to the room, and edit it.
    old_draw = _draw
    function _draw()
    local dz = sin(time())*5

Is it possible to configure the camera such that it follows the player in a game?

via a script placed inside the player folder (will add code once I've got that worked out)

Is there a way to evaluate a function call stored as a string, say "cls(2)"? I tried


but nope; no such beast.

How does one create a door, then link 2 instances of it across rooms? I've read the docs but an overview of what makes a door is not enough. Step-by-step, up to date instructions would really help. <nudge> @zep. :)

I have a controller connected to my laptop. To configure pico-8 for it, I did : launch Gamepad Tool > Copy Mapping String > append string to sdl_controllers.txt > relaunch pico-8. This works well.

Now, I would like to use the controller's shoulder buttons as replacements for the d-pad's dpleft (btn 0) and dpright (btn 1), respectively. Can this be done at all? Note that this is not for exported (to html) games but rather to those launched from the pico-8 console.

To be clear, I'd like to control a pico-8 game using a gamepad's shoulder buttons.

GamepadTool mapping string, as entered in sdl_controllers.txt is this:
03000000bd12000015d0000000010000,Tomee SNES USB Controller,a:b2,b:b1,back:b8,dpdown:+a1,dpleft:-a0,dpright:+a0,dpup:-a1,leftshoulder:b4,rightshoulder:b5,start:b9,x:b3,y:b0,platform:Mac OS X,

Here's my 558-char TweetTweetJam3 entry, including memory poked sfx (thanks to @eruonna for documenting that).

How do I create a middle c note in sfx 0 programmatically? I'm not sure on the formula to calculate the offset from 0x6000.

I want to control my pico game via html element event handlers. Given that, what memory address (pico8_gpio offset) must I poke at if I want to simulate a btn(0) event? Also, what's the offset for simulating additional player actions, say, btn(0,1)? Thanks.

Is there a shortcut for editor code tab switching? Couldn't find it in the docs.

(This may sound convoluted)

Is it possible to invoke an embedded ("export html") pico-8 program's functions from an external javascript file?

In this particular case, I wrote a .js app that fetches remote data asynchronously (via ajax). I then want to map that data to a sequence of pico-8 program function names, invoking each one in turn at regular intervals.

I often browse the pico-8 forums on my mobile. On my phone (Samsung S4), I have to squint like a maniac because the contents of the pages are not rescaled by the browser, which they would be if the following viewport meta was on each page:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" />

Can the person responsible for these forums (and web site in general) add that so that I can go back to "squintless" reading. :)

Hi all.
The following code doesn't work -- players don't get drawn.
What am I doing wrong?
Thanks in advance.

players = {}

function make_player(col)
  local p = {}
  p.x = 0
  p.y = 0
  p.color = col
  return p

function draw_player(p)

function _init()
  players.home = make_player(1)
  players.visitor = make_player(8)

function _draw()
  foreach(players, function(p) draw_player(p))

Could someone explain how glitch effects similar to Benjamin Soulé's Mr.Beam were done? No code as much as an overview.

Thanks in advance.
