Quadtree

An easy-to-modify Quadtree with standard 2D implementation.

Usage

Standard 2D collision detection supports points and bounds (rectangular regions):

use \Quadtree\Quadtree;
use \Quadtree\Geometry\Bounds;
use \Quadtree\Geometry\Point;

$qtBounds = new Bounds(1024, 1024);
$qt = new Quadtree($qtBounds);

$qt->insert(new Bounds(300, 200)); // TRUE
$qt->insert(new Bounds(100, 50, 20, 10)); // FALSE
$qt->insert(new Point(250, 100)); // FALSE
$qt->insert(new Point(2000, 500)); // FALSE
$qt->insert(new Point(299, 199)); // TRUE

Need more logic for collision detection? Create your own ICollisionDetector. Need to insert other objects then points and bounds? Implement Insertable interface.

Installation

Use Composer:

{
    "require": {
        "michalsanger/quadtree": "0.0.1"
    },
    "repositories": [
        {
            "type": "git",
            "url": "https://github.com/michalsanger/php-quadtree.git"
        }
    ]
}

Tests

Due to Nette Tester tests are simple and readable. Run:
