Rust Cheat Sheet

Variables & Mutability

Variables are immutable by default. This makes Rust safer and makes concurrency easier.
Immutable means once a value is bound to that variable, it cannot be changed.
For example:

fn main() {
 let x = 5;

Technical Art Director/Web Developer/SysAdmin

My name is Chris Sprance. I am an artist, programmer, maker, and man of many hats. Proficient in the next-gen game art workflow with a deep understanding of the technical and procedural content pipeline including the constraints that revolve around games and real-time content. With over 13+ years of experience working in the AAA and indie games industry I've been a part of a lot of problem solving and enjoyed every second of it!

Miscreated Servers

RCON commands and server configuration help

Available Commands:

sv_servername "Name of server in quotes"
wm_timeScale 3 How Fast time moves
wm_forceTime -1 Force a current time
g_pinglimit 0 Ping required to join

Conventions

A = [xA, yA] is a point on the 2D plane. Same for B, C, ...
lengths are in any unit (ex: pixels)
code snippets are in JavaScript

Degrees to radians

angleRad = angleDeg * Math.PI / 180;

	// This is the point we want to find barycentric coordinates of
	vector p = point(0, "P", 3);

	// These are the vertices of the main triangle we want to find coordinates for
	vector v1 = point(0, "P", 0),
	v2 = point(0, "P", 1),
	v3 = point(0, "P", 2);

	// Edge Vectors of the main triangle
	vector e1 = v3 - v2,

	// How far points in grid cells can go from the center of the grid cell. Setting this to a value above 0.5 will make the noise discontinuous, and there will be visible seams.
	// It is reccomended to leave this at 0.3.
	const float CLOVER_NOISE_2D_POINT_SPREAD = .3;

	// The value of pi. Used in the offset function.
	const float CLOVER_NOISE_2D_PI = radians(180.);

	// Hashes a 2D vector into a point. It isn't 100% random, but it's good enough for clover noise to appear random.
	float clover_noise_2d_hash(vec2 p) {
	return fract(1e4 * sin(17.0 * p.x + p.y * 0.1) * (0.1 + abs(sin(p.y * 13.0 + p.x))));
