MarioLiebisch / aoc2021-day1.gd

Created December 1, 2021 09:48

Solution for Advent of Code 2021 day 1 using GDScript

	# Execute with:
	# godot --no-window -s aoc2021-day1.gd

	extends SceneTree

	func read_ints(file: String) -> Array:
	var ints = []
	var f = File.new()
	f.open(file, File.READ)
	if f.is_open():

MarioLiebisch / morse.ino

Created March 24, 2020 13:52

Simplified Morse Code Generator for Arduino

	// Pins used for this
	#define LED_PIN 13
	#define BUZZER_PIN 11

	// The time in milliseconds for short signals
	#define TIME_UNIT 100
	// Frequency used
	// For classic codes both should match
	#define FREQUENCY_LONG 220
	#define FREQUENCY_SHORT 440

MarioLiebisch / hexagons.cpp

Created August 29, 2019 06:43

A simple SFML program to draw a colored, hexagonal grid.

	#include <SFML/Graphics.hpp>
	#include <vector>

	int main()
	{
	sf::RenderWindow window({640, 480}, "Hexagons", sf::Style::Default, sf::ContextSettings(0, 0, 8));

	// We're simply abusing a `CircleShape` here,
	// since a circle defined by 6 points IS a hexagon!
	sf::CircleShape hexagon(25, 6);

MarioLiebisch / conext.hpp

Created July 14, 2019 12:42

An old simple wrapper I've used in a few old tools to get cross-platform coloring in console

MarioLiebisch / timer.cpp

Created May 6, 2019 18:11

Quick and simple timer example using SFML

	#include <SFML/Graphics.hpp>
	#include <sstream>
	#include <iomanip>

	int main(int argc, char **argv) {
	sf::RenderWindow window(sf::VideoMode(300, 100), "Timer Test", sf::Style::Default);
	window.setVerticalSyncEnabled(true);

	sf::Font font;
	font.loadFromFile("Arial.ttf");

MarioLiebisch / statswindow.cpp

Created August 26, 2018 19:02

Small example how to add stats counting to a SFML `sf::RenderWindow`. Release builds could just use `sf::RenderWindow` directly instead. Note this isn't necessarily 100% perfect or correct; written from memory.

	#include <SFML/Graphics.hpp>
	#include <sstream>

	class RenderWindowStats : public sf::RenderWindow {
	public:
	RenderWindowStats() : RenderWindow({640, 480}, "Test") {
	}

	void draw(sf::Drawable &dr, sf::RenderStates states = sf::RenderStates()) {
	++mDrawCallsTemp;

MarioLiebisch / getself.cpp

Created July 22, 2018 16:18

Small utility function to get a running program's own executable path. This should work even if it's called using a symbolic link.

	std::string getSelf()
	{
	char buf[1024] = { 0 };
	#ifdef WIN32
	DWORD ret = GetModuleFileNameA(NULL, buf, sizeof(buf));
	if (ret && ret != sizeof(buf)) {
	std::string res(buf);
	for (auto &c : res)
	if (c == '\\')
	c = '/';

MarioLiebisch / fpsmeter.cpp

Last active July 16, 2018 08:09

A simple to use, self-containing FPS meter for SFML programs I use for testing

	/*
	Usage:

	* Load a font, if you don't have one yet
	* Create the `FpsMeter` object
	* Optional: Set a position
	* Draw the meter

	sf::Font font;
	font.loadFromFile("myfont.ttf");

MarioLiebisch / observable.cpp

Created July 10, 2018 13:49

Simple implementation of an observable variable that will trigger once its value is changed (and which could be adjusted in the callback). This was really just a random idea, it's not perfect by any means.

	#include <iostream>
	#include <functional>
	#include <string>

	// Definee an `Observable` class.
	// This works as a wrapper around a variable of any type.
	// Once it's assigned a new value, a predefined callback is defined to react on this.
	template<typename T>
	class Observable {
	public:

MarioLiebisch / circletext.cpp

Last active May 12, 2018 16:54

A minimalistic example to print text in a circle using SFML. (Example output: https://i.imgur.com/2M2OURz.png)

	#include <SFML/Graphics.hpp>

	int main(int argc, char **argv) {
	sf::RenderWindow window(sf::VideoMode(800, 600), "Circle Text", sf::Style::Default);
	window.setVerticalSyncEnabled(true);

	sf::Font font;
	font.loadFromFile("arial.ttf");

	sf::Text text("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean ut ultrices ante. Aliquam ornare eu enim eget accumsan.", font);
