Controller2D

A simple Character Controller for 2D games that require tight movement. It requieres a Collider2D.

Notice: Although the project is on a higher version of Unity, the scripts should be compatible with any 2018 or 2019 version of Unity.

Usage

You can add the add this controller through the Unity Package Manager using this repository URL + the specific version you want, you can check the different versions under the tags of the repo. For example:

https://github.com/502Studios/Controller2D.git#1.2.0

Collider type

By default the collision shape to cast against the environment will be a square based on the bounds of the Collider attached to the game object. If you set a Capsule Collider 2D the controller will use a Capsule to check for collisions.

Solid Mask

Defines the layer masks on which the controller should check for collisions.

Slopes

If the Manage Slopes toggle is active the Controller will be able to ascend/descend slopes, to set the max slope angle use the Max Slope Angle slider.

Methods

  public void Move(Vector3 deltaStep)

Will try to move the controller in the given direction, will resolve collisions and will align accordingly.

  public CollisionState CollisionState()

A Struct that provides collision information from last frame, will provide collision data for above, below, left and right collisions.

Trigger Detection

You can bind delegate events to detect triggers, in order to detect a trigger the controller or the other GO should have a Collider2D in Trigger mode and a RigidBody2D set as Kitematic or Static to avoid Physics issues.

You can bind to:

• OnTriggerEnter
• OnTriggerStay
• OnTriggerExit

    private void Awake()
    {
        controller2D = GetComponent<Controller2D>();
        controller2D.onTriggerEnter += OnTriggerEnter2D;
    }

    private void OnTriggerEnter2D(Collider2D collision)
    {
        Destroy(collision.gameObject);
    }
