PICO 8 Handheld

Tue, 29 Mar 2016 13:11:36 UTC

I've been working on a handheld for playing PICO-8. It uses a Raspberry Pi Zero, and an Adafruit 1.8" screen for displaying. The screen size is 160x128, so PICO-8 fits perfectly (alright, centered). The buttons and button PCB are robbed from a USB NES controller I had. The case is 3D printed to fit the parts (very tightly). Total size of the unit is 120x45x20mm.

The screen mirrors the output of the HDMI, so you can play with either the TV or built in screen. Currently, it has no internal battery, but I'd like to find a good lipo battery to add. In the meantime, I just connect a USB power stick.

_draw vertical flip

I'm trying to port Write Fight for playing on a cocktail cabinet (players at opposite ends of a face-up screen). So one of the things I want to do is write text & HUD elements oriented to the player who collected it. Is there a function, such as camera(), where I could flip/rotate all draw calls until reset?

I'm doing work-arounds in the meantime, but I thought I'd throw out the question.
Thanks.

Nesting While loops

I don't know if this is a bug or feature, but it seems to me that nested loops do not work.

I attempted to use the following code, debugging the text showed that only one loop occurred:

local x=0
local y=0
while(x<16) do
 while(y<16) do
  val=mget(x,y)
  print(val)
  y+=1
 end
 x+=1
end

I don't know if this is intended or a limit of lua, but I was able to work around it with the following code:

local i=0
while(i<256) do
 local x=i%16
 local y=(i-x)/16
 val=mget(x,y)
 print(val)
 i+=1
end
