VisualizaçõesHow do I disable diagonal movement in Unity 2D?
I would like to ask if there is a way to disable diagonal movement in Unity 2D. The thing is when I press 'W' + 'D'(move key) at the same time then the character starts to move diagonally. So instead of the character moving diagonal when combining button press, I want it to go completely straight instead if I press 'd' or any other key to move even if I'm still pressing the other button at the same time. So to say prioritize the function of the last button I pressed.
Here's a short video to explain my problem further .
And here's the code for my character movement.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class keycontrol : MonoBehaviour
{
public float moveSpeed = 0f;
public Rigidbody2D rb2d;
Vector2 movement;
public Animator animator;
// Update is called once per frame
void Update()
{
movement.x = Input.GetAxisRaw("Horizontal");
movement.y = Input.GetAxisRaw("Vertical");
animator.SetFloat("walk_right", movement.x);
animator.SetFloat("walk_left", -movement.x);
animator.SetFloat("walk_down", -movement.y);
animator.SetFloat("walk_up", movement.y);
}
void FixedUpdate()
{
rb2d.MovePosition(rb2d.position + movement * moveSpeed * Time.fixedDeltaTime);
if(Input.GetKey("left shift"))
{
moveSpeed = 200 * Time.deltaTime;
animator.speed = 1.5f;
}
else
{
moveSpeed = 110 * Time.deltaTime;
animator.speed = 1f;
}
}
}
Thanks for help

A simple way to do this is to prioritize one axis over the other and just wrap the other check in a condition.
movement.x = Input.GetAxisRaw("Horizontal");
if (movement.x != 0)
{
movement.y = Input.GetAxisRaw("Vertical");
}
However, this can fail, because depending on your input, the axis might return values close to zero when using a controller. In this case, you could just get both values and check for the larger one.
movement.x = Input.GetAxisRaw("Horizontal");
movement.y = Input.GetAxisRaw("Vertical");
if (Mathf.Abs(movement.x) > Mathf.Abs(movement.y))
{
movement.y = 0;
}
else
{
movement.x = 0;
}

Sharing as an answer since I can't comment on this post, you should check out the new input system unity released recently: https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/manual/QuickStartGuide.html
It gives better control over inputs such as event systems so you can lock the movement until the first key is released.

You can handle the movement only in one of the axis handled each chance in the code, find draft below:
bool isXMoving;
bool isYMoving;
// Update is called once per frame
void Update()
{
if (Input.GetAxisRaw("Horizontal") != 0f && !isYMoving) {
movement.x = Input.GetAxisRaw("Horizontal");
movement.y = 0;
isXMoving = true;
isYMoving = false;
}
if (Input.GetAxisRaw("Horizontal") != 0f && !isXMoving) {
movement.y = Input.GetAxisRaw("Vertical");
movement.x = 0;
isYMoving = true;
isXMoving = false;
}
Debug.Log($"X: {movement.x} Y: {movement.y}"); //check
animator.SetFloat("walk_right", movement.x);
animator.SetFloat("walk_left", -movement.x);
animator.SetFloat("walk_down", -movement.y);
animator.SetFloat("walk_up", movement.y);
}
