Can not call function matmul and matmul3d

Thu, 13 Feb 2025 04:10:47 UTC

(version 0.1.1d, Windows 10)

I can not call function matmul() and matmul3d() directlly.

At the same time, they can be called as a method of Class userdata

a=vec(1,2,3)
b=vec(2,2,2)
matmul(a,b,1) -- runtime error, attempt to call a nil value (global 'matmul')
a:matmul(b,1) -- OK

Get Support to PICO-8/Picotron in VSCode

Sat, 26 Oct 2024 13:56:43 UTC

pico-api is a project consisting of definition files for the sumneko/lua extension for VSCode, allowing you to write PICO-8 or Picotron programs with the support of modern editor features.

Usage

Install and enable sumneko/Lua extensions in VSCode Marketplace

Download the repo from Github(pico8 or picotron)
Put the folder .vscode/ and library/ into your workspace.
Create Lua files in your VSCode workspace.
Create a cartridge and include the Lua file in it with:

-- picotron
cd("/myproj")
include("main.lua")

-- pico8
#include main.lua

Then you can write code in the workspace of VSCode and enjoy code prompts, formatting, AI copilot, etc.

We really need some new precautions for spams

Printh Easily with VSCode

Tue, 05 Sep 2023 11:20:34 UTC

I found a simple way to use printh on Windows without any setup by using Terminal in VSCode.

Using Lnk file

Drag and drop the lnk of PICO-8 into VSCode Terminal;
Press Enter to run it;
Use printh in PICO-8!

Now printh will output its info to VSCode Terminal.

Using p8 file in VSCode

And if you set pico-8.exe as the default program to open your p8 file, you can just drag and drop your p8 file in the VSCode to Terminal. It will open PICO-8 and load the cart and printh still works.

Another way by editing lnk file: https://www.lexaloffle.com/bbs/?tid=42367

A mistake in manual about coroutine

Mon, 03 Jul 2023 06:38:01 UTC

@zep There is a mistake in the PICO-8 manual.

6.14 Additional Lua Features > Coroutines > costatus(c)

Return the status of coroutine C as a string:
  "running"
  "suspended"
  "dead"

The status "normal" is missing.

When coroutine A calls coroutine B, and you check the status of A in B, you will get "normal".
