Collider2D

The Collider2D class, part of the zygarde::physics::components namespace, represents the core 2D collision detection mechanism. It is used by other components, such as BoxCollider2D, to manage collision layers and handle collision events.

Overview​

Collider2D is a final class designed to handle low-level collision detection and management within a physics engine. It maintains a queue of detected collisions and uses layer-based filtering to determine which objects interact.

Properties​

  • include_layers: A vector of integers specifying the layers the collider should include in its checks.
  • collision_layers: A vector of integers specifying the collision layers the collider should respond to.
  • collision_queue: Queue of collisions the collider has.

Example Usage​

The Collider2D class is a private utility within BoxCollider2D, meaning it is not intended for direct use outside of its friend class. Below is an example of how BoxCollider2D interacts with Collider2D to process collisions.

#include "box_collider_2_d.hpp"

using namespace zygarde::physics::components;

BoxCollider2D boxCollider(Vector2f(100.0f, 50.0f), {1, 2}, {1});

// Check for collisions in BoxCollider2D, which uses Collider2D internally
if (boxCollider.HasCollision()) {
    auto collision = boxCollider.GetNextCollision();
    // Process collision details
}
