If you're reading this document, you're probably one of many people confused about how to implement OOP-like classes in Lua. But no worries! This document aims to explain all the fundamental concepts in beginner-friendly language.

Metatables

Before we start, we need to talk about metatables. These are Lua's way of allowing users to overload operators. Operators include arithmetic +, -, *, /, etc., but also things like indexing tables a[b], creating new indices in tables a[b] = c, function calls, a(b, c, d), you get the idea.

We can set the metatable of a table using setmetatable(t, metatable). The metatable is another table, that contains fields for overriding

using UnityEngine;

/// <summary>
/// Small helper class to convert viewport, screen or world positions to canvas space.
/// Only works with screen space canvases.
/// </summary>
/// <example>
/// <code>
/// objectOnCanvasRectTransform.anchoredPosition = specificCanvas.WorldToCanvasPoint(worldspaceTransform.position);
/// </code>
