atan2(1,0x8000.0001) returns 0.25, as expected. However atan2(1,0x8000.0000) returns 0.75.

This is the kind of stuff that could be compiler-specific because 0x80000000 is a bit special, however I get this on both Windows and Linux (64-bit).

Hey there, I'm just starting here with Pico-8, trying to understand the syntax.

I just want to create 2 one dimensional arrays numbered 1 to 10, and fill them with the value 63. But I can't seem to figure out how. Can anyone assist with this please?

x={}
y={}

for i = 1,10,1 do
x[i] = 63
y[i] = 63
end

A game about becoming beautiful.

You are but a wee skeleton residing in the Necromancer's Tower. You realize that your skull would be so much prettier if you had some rubies where your eyes would be. Rumor has it that the necromancer holds some very impressive gems. Maybe you should go take a look?

The upcoming Pico-8 0.2.6 release will introduce wavetable synthesis via "waveform instruments". Any of this may change before release so I will try to update it as I discover new info about the feature. The waveform instruments are stored in the same sfx indices as regular instruments (0-7) and use a similar encoding scheme to regular sfx:

Bytes 0-63

The first 64 bytes of the sfx contain one signed 8-bit sample per byte. Pico-8 uses signed 16-bit numbers, so signed 8-bit values from -128 to -1 are represented as 128 to 255, while 0 to 127 are represented normally. Signed 8-bit values outside the -96 to 96 range will appear cropped in the visual editor, although it does appear to be possible to draw values in the full range by dragging the mouse cursor beyond the border.

Regarding PCM playback, Pico-8's tracker updates at about 120.4918Hz, and at 64 signed 8-bit samples per cycle, the sample rate would be about 7711.4752Hz. However, because the closest playback frequencies available are A#-0 (A#-2 in standard pitch notation @ 116.54Hz) or B-0 (B-2 in standard pitch notation @ 123.47Hz), it appears that smooth PCM playback will not be possible by stringing waveform instruments together, as waveforms would not have the chance to play exactly one oscillation per tick; instead being slightly cropped or slightly looped (and then cropped). This will result in clipping/distortion, and weird tuning artifacts.

Welcome to Pico Drummer! It’s a small rhythm generator with just two sounds.

Each hand is triggering its own sound when it hits the drum.
If you want to change the speed you need to change the amplitude of the hands movement. To do that, hold the hand with the mouse and move it up or down and then release it on a certain hight. You can even stop the hand by putting it on top or the drum.

You may also access sound and rhythm settings by hovering your mouse over one if the two drums. Each drum represents its own sound and a hand that beats it. Both of them have 3 tabs of settings, that you can switch by clicking the drum.

• First tab of the settings is speed adjustment and clock divider. Use left and right arrows to adjust hand speed. If you press right, the hand will speed up for a split second, and if you press left, it will slow down. That way you can synchronize hands if they are beating with same speed but out of sync. Up and down arrows changes the clock division number, which is 2 by default. You can create some interesting rhythms by dividing speed of each hand differently.

I don't know English this, it's a translator, sorry for the spelling mistakes, this is a recreation of Jump with two more games.

This is a work-in-progress game of picross. Has someone else used the name picocross? Probably, but this is my one!
It currently only has one puzzle and the game ends once you beat it.

How to play

Use arrows to move the cursor.
Press (X) to place a tile and (O) to place a cross. You can use the crosses to show where tiles definitely are not.
Press (X) or (O) to remove a tile / cross.
Press (X) to highlight / un-highlight a number. You can do this to keep track of which numbers have been solved.

How to play picross

To discover the hidden picture, you need to determine where the tiles must be placed.
For each column and each row you are given a set of numbers. These numbers tell you how many consecutive tiles are in that row or column. Multiple numbers means multiple 'blocks' of consecutive tiles in the same order as the numbers, that are separate from each other.

So, I'm new to PICO-8 (bought it a few hours ago) and im playing around with a simple open world game (I've called it a GTA test, maybe to use for a clone game in the future.) and i am just wondering how i would go about implementing collision in the map (for buildings and such which haven't been added yet). Is that something

I've used SpaceCat's tutorial so far and added my own camera follow code and made a simple map.

This is what I have so far, it is literally just the movement code and a simple map
