Broadphase<T extends Hitbox<T>> class abstract

The Broadphase class is used to make collision detection more efficient by doing a rough estimation of which hitboxes that can collide before their actual intersections are calculated.

Currently there are two implementations of Broadphase:

• Sweep is the simplest system. It simply short-circuits potential collisions based on the horizontal (x) position of the components in question. It is the default implementation when you use HasCollisionDetection.
• QuadTree works faster in some cases. It requires additional setup and works only with fixed-size maps. See HasQuadTreeCollisionDetection for details.

Always experiment to see which approach works best for your game.

Methods

add(T item) → void

Adds an item to the broadphase. Should be called in a CollisionDetection class while adding a hitbox into its collision detection system.

addAll(Iterable<T> items) → void

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

query() → Iterable<CollisionProspect<T>>

Returns the potential hitbox collisions

remove(T item) → void

Removes an item from the broadphase. Should be called in a CollisionDetection class while removing a hitbox from its collision detection system.

removeAll(Iterable<T> items) → void

toString() → String

A string representation of this object.

inherited

update() → void

This method can be used if there are things that needs to be prepared in each tick.

Operators

operator ==(Object other) → bool

The equality operator.
