The Good Pills 0.1

This is my first attempt on creating a game using PICO-8 within 24h.

The goal is simple: your character need to eat the good pills, knowing that the pill should be of the same color as the character.

• Use Left and Right arrow keys to move the character, and Down arrow to Speed up the Pill
• Use X and Z keys to change the character's color
• Put you under a pill to eat it

Have fun!

So I was planning on giving abilities to my player character in the form of auras. My question is: Is it possible to code in the aura color changing (i.e. from blue, red, purple, etc
) with a core sprite, or does each one have to be drawn out individually?

I like the new printable button glyphs introduced in 0.1.8. This is a small idea, but it'd be cool if they were allowed chars in variable names. Right now any appearance outside of a string is a syntax error.

Bonus: pre-define L R U D O X to equal their btn() values, so I can test btn(L) as well as btn(0).

Defective PICO-8, please help :(

Please help :(

I just upgraded to v0.1.8, and now when in SPLORE, attempting to access 'NEW' gives the error 'UNABLE TO CONNECT TO BBS' but every other tab can connect as per usual. Does anyone else get this? Is this a known bug?

recommended soundtrack

This is a shabby prototype of a combat system.
I suppose the main influences are Ocarina of Time and Golden Sun.
Maybe the over-the-shoulder perspective is heresy on a platform like this, I was thinking it's a bit like pokemon though.
I think the most interesting feature is the way your mobility is limited. your position is locked to north/south/east/west and you can move between a near/far plane, like this:

It would be great if it was possible to draw in the sprite and map editors using only the keyboard (i.e. without requiring the use of a mouse/touchpad). With sprites being only 8x8, I find myself wanting an easy way to precisely move the cursor by one pixel at a time instead of the inherent looseness/analogueness of a mouse/touchpad.

I also think in general it might be thematically fitting for all of PICO-8's editor modes to be completely useable without requiring a mouse, to be similar to older computers for which mice were either optional peripherals or not present at all :)

Update 2019-05-13: Use the "Enter Menu" to "load" some code examples.
Update 2017-05-14: The sonification can be switched off :-) (or rather, you need to explicitly turn it on in the X-menu).
Update 2017-05-05: Added crazily sounding sonification.
Update 2017-04-24: Made the UI a bit more clear and fixed some bugs.

TL;DR:

Hold X, pres DOWN once, release X, and watch the nerdy numbers fill your screen.

First version done in one night.
I'm pretty surprised by what can be done with PICO-8 in so little time.

When using _update60(), btnp() timing is also 2x faster, which makes it much less useful - the time to let go before the press is repeated is halved to 0.12s, and time between repeats also goes down.

This matches the docs (which say frames), but doesn't feel like it was intended - maybe something to be fixed for 0.1.9?

Just wanted to make sure I understood how things worked before diving into it too deeply.

So I understand the idea behind the pattern editor, I've used it to make short sound clips and stuff (and then these are obviously arranged within the music editor to make different instrument tracks, etc)

From what I can tell at a surface glance though, is that the music editor only supports one song. Is that correct? I get the impression that I can set the loop start/end points to choose between different pattern sets to allow for multiple songs (eg 0-7 might be song 1, 8-16 could be song 2, etc). Additionally, I assume that I can create my own pattern arrangements on the fly by means of poke()

Anyone know for sure?

Bezier curve drawing! Z/X to change nodes, arrows to move the node around.

Is there any way to rotate or flip a sprite map?

I have a platformer room that is a sprite map but want to be able to rotate/flip the map so I can get several rooms out of a single drawn room.

My alternative is to use the map as a blueprint and then just draw the sprites myself in the loop at coordinates so I can rotate them that way, but sounds like quite a bit of effort (for me and the P8). So hoping I can manipulate the sprite map somehow.

Hey, just a simple question:

Does Pico-8 support vnc on the raspberry pi?

Thanks

Greetings.

I have gotten trouble in coding a part of my game. The core gameplay is that a dragon goes through a randomly-generated dungeon, finds a treasure, and goes back to the start. The problem is that I had trouble knowing just how to place the dragon and the treasure. The idea is that the dragon would have to travel a considerable distance before finding the treasure, which is located at a "dead end". The code I used in the dungeon generation is here: http://www.dangerousru.in/p8/p8gen.html

I appreciate any help I get here.

Hi,

The other thread about converting numbers to hex strings got me wondering if it was possible to do the same with fixed point data. (I did try searching here first but didn't find anything about this specifically)

I wrote a quick test to dump the bits out, but for floats I'm not sure where to find the fractional part. I figured it'd be in the top byte, but as the last test shows, it's not there (or my code is wrong). Is it possible to get at this data?

Thanks

function convert(value)
  local binary = ""
  for i=1,16 do
    local shift = shl(1,i-1)
    binary=abs(shr(band(shift,value),i-1))..binary
  end
  print("convert "..value.." to binary:")
  print(binary)

  local integerval = 0
  for k=1,16 do
    local str = shl(sub(binary, k, k),16-k)
    integerval += str
  end
  print("and back again: "..integerval)
  print("")
end

function _init()
  cls()
  convert(0xc0de)
  convert(12345)
  convert(3.14159)
end

I'm trying to make a platformer that just uses pixel colors as a way to check for the ground/walls of a level, no sprite flags. At first it seems to work, the guy (stick) moves left/right and jumps on the initial ground just fine. But then when you jump up on the platform to the right and either walk or jump off back to the left, he sinks into the ground.

See code below, but what I'm doing is checking the pixel immediately below the stick to see if it's a ground color and if so, stop applying the gravity. Seems simple enough...made sense to me but I'm clearly missing something.

I'm happy with the jumping action, it's nice and smooth and such but landing seems to be an issue. If anyone has suggestions for my code or just insight in general, I appreciate it. Making a platformer is new to me...I usually make shmup games :)

NOTE: Code as-is is not checking for left/right collisions, just ground for jumping.
