previous versions :

New version of Tubular Craze, a clone of Pipe Mania.

The goal is to connect pipes from the Start tile (S) to the End tile (E) with at least a number of pipes (the number below "LEFT" in the lower left).

You can see the 5 next pipes to lay down on the left, the pipe with a red outline is the current one to place (it's the same as you cursor).

There are still some annoying bugs:

Anchors are sometimes overlapping, making them impossible to move
I'm not sure all the puzzles have a valid solution
There is an easy way to cheat

Here is a cartridge I was working on and forgot about. It's a happy surprise that it is more or less working!

Here is a fun math game, inspired by the game "24", where you have to make mental calculation to obtain a target number with only the 4 integers given to you.

You can use parenthesis and standard operators (+,-,*,/) to get to the result.

Good luck!

The fun part in this cartridge is the calculator which includes a parsing Shunting-yard algorithm to generate and evaluate an RPN expression.

1.4 Update :

Fix an issue when there was still numbers on the stack when evaluating an expression (like "829" evaluated to "9", instead of giving an error)

1.3 Update :

Button X deletes the last character
The delete button is replaced by a "c" (like in a calculator) to reset the guess

1.2 Update :

Fixed a bug with the shunting yard algorithm (the test for operator precedence was incorrect)
Added a debug/test mode for RPN calculation (set the scene=2)

1.1 Update :

Score, timer and difficulty indicator
Fireworks when a correct solution is guessed (from the Fireworks effects by Saccharine)
Some invalid calculations are detected (not all)
Fixed some other bugs

Hi,

I wrote a perl script to convert a cartridge spritesheet to png and back. This way, you can edit your sprites in your favorite software and update the cartridge when done.

bitfield manipulation

Tue, 22 Sep 2015 16:35:00 UTC

Hi,

Is there a way to make bitwise operations in pico8?
Otherwise, I don't understand how btnwe are supposed to use the bitfields returned by the functions btn() and fget(n).

Shouldn't we be able to do something like :

flag2_set = fget(tile) & 2

I know fget(tile, 2) would work, but I don't see how to use the bitfield. Am I missing something obvious?

Rewrote the code nearly from scratch, levels are map are
redone collisions based on the Wall Collision Example cartridge

First attempt at Pico8 tracker with the Arkanoid music
Multiple levels are now playable in one game (if you are good enough)
Retry OK after Game Over
Better collision and ball direction
Ball speed varies according to where it bounces on the paddle
Boss sprite

0.02

multiple levels, although for the moment you can access them only by changing the start_level variable
Oooh! Shiny start page!
More sprites
Collision still buggy
Sticky paddle when starting / losing life

Todo list

Power ups
