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;

Chris Sprance

Technical Art Director | Character TD | Pipeline, Procedural & Full-Stack Dev

Over 13 years of AAA and indie game development experience specializing in character technical art, procedural content systems, pipeline engineering, and full-stack development. I bridge the gap between art, engineering, and web — designing procedural workflows, architecting production tools, and leading technical art teams to ship polished characters and systems on time. Whether collaborating with engineers on gameplay or editor level tooling, building full-stack web applications to support live games, or solving complex character pipeline problems, I bring both deep hands-on execution and strategic leadership across disciplines.

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))));
