Hi, I am confused how I can Lerp from inputDirection to targetInput when inputDirection has not yet been initialized, only defined. This piece of code is from a tutorial and I know it works, but I don’t know why. My guess is that inputDirection is a special type of Vector3 that is a reference to user input or that the default value for Vector3 is (0, 0, 0), but my research so far has been unsuccessful.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;
public class PlayerMovement : MonoBehaviour
{
private PlayerInputActions inputActions;
private Vector2 movementInput;
[SerializeField]
private float moveSpeed = 10f;
private Vector3 inputDirection;
private Vector3 moveVector;
private Quaternion currentRotation;
void Awake()
{
inputActions = new PlayerInputActions();
inputActions.Player.Movement.performed += context => movementInput = context.ReadValue<Vector2>();
//Reads a Vector2 value from the action callback, stores it in the movementInput variable, and adds movementInput to the performed action event of the player
}
void FixedUpdate()
{
float h = movementInput.x;
float v = movementInput.y;
//y value in the middle
//0 since no jump
Vector3 targetInput = new Vector3(h, 0, v);
inputDirection = Vector3.Lerp(inputDirection, targetInput, Time.deltaTime * 10f);
}
}
I don’t see any indication that inputDirection is actually related to any user input.
Even if you don’t see it there, the inputDirection variable has an init value. So i suspect (like you did) that the vector3 default init from c# sets them all to 0. To test this, you can just declare a vector3 somewhere in your code and Debug.Log() it. It will print all values and if my guess is right, it should print (0,0,0).
EDITED
Vector3 is a struct and NOT a class, C# inits it to (0,0,0).
