Joystick Diagonal?

Questions & Answers
1

Hello friends, I have currently got some code that let’s me trigger animations with joystick input. I can do Up,Down,Left,Right but I don’t know how to do diagonal

can someone help me please?

   if (joystick1.Horizontal >= 0.9f)


                {
                    anim.Play("NewShove");
                }

I can recommend the new InputSystem in general (see InputSystem package).

With the attached code, I created an InputProcessor that rotates the raw Input by a configurable amount of degrees (45 for diagonal).
Just put the script somewhere in your project and add “Rotate” as a Processor.

using UnityEditor;
using UnityEngine;
using UnityEngine.InputSystem;

/// <summary>
/// Input processor to rotate a two dimensional input by the configured degrees
/// </summary>
#if UNITY_EDITOR
[InitializeOnLoad]
#endif
public class RotateProcessor : InputProcessor<Vector2> {
    [SerializeField, Tooltip("The angle in degrees to rotate the vector by")]
    private float rotateDegrees = 45f;

#if UNITY_EDITOR
    static RotateProcessor() {
        Initialize();
    }
#endif

    [RuntimeInitializeOnLoadMethod]
    private static void Initialize() {
        InputSystem.RegisterProcessor<RotateProcessor>();
    }

    /// <summary>Rotates the given vector <paramref name="value"/> by the configured <see cref="rotateDegrees"/></summary>
    public override Vector2 Process(Vector2 value, InputControl control) {
        float sin = Mathf.Sin(degrees * Mathf.Deg2Rad);
        float cos = Mathf.Cos(degrees * Mathf.Deg2Rad);
        float vx = value.x;
        float vy = value.y;
        value.x = cos * vx - sin * vy;
        value.y = sin * vx + cos * vy;
        return value;
    }
}

If you just want to rotate this one joystick, here’s a snippet:

float degrees = 45;
float vx = joystick1.Horizontal;
float vy = joystick1.Vertical;
float sin = Mathf.Sin(degrees * Mathf.Deg2Rad);
float cos = Mathf.Cos(degrees * Mathf.Deg2Rad);
Vector2 rotated = new Vector2(cos * tx - sin * ty, sin * tx + cos * ty);
if(rotated.x >= 0.9f) anim.Play("NewShove");

Thank you so much for that in depth response @detzt!

However, I’m am not sure on how to implement your code as I am new in the C# game. Do you know a fix that could be more suited to my current approach (Simple) haha.

Thank’s again :slight_smile:
