Removing The Slide From Transform.Translate

Questions & Answers
1

I’m trying to have a simple cube move across the screen vertically and horizontally but at the same time diagonally. I got all of this down with a simple transform.Translate but my problem is that I have a “slide” when I go in one direction then switch to another for example: I got up and decide to go left, I slide up slightly before I fully stop.

using UnityEngine;
using System.Collections;

public class PlayerControls : MonoBehaviour {

    public GameObject player;
    public float speed = 10.0f;
    public float transH;
    public float transV;


    void Update()
    {
        PlayerProperties playerProp = GetComponent<PlayerProperties>();

        if(transV >= 0.001f && transH == 0)
        {
            playerProp.playerState = PlayerProperties.PlayerState.Up;
            playerProp.changePlayer = true;
        }

        if (transV <= -0.001f && transH == 0)
        {
            playerProp.playerState = PlayerProperties.PlayerState.Down;
            playerProp.changePlayer = true;

        }

        if (transV == 0 && transH <= -0.001f)
        {
            playerProp.playerState = PlayerProperties.PlayerState.Left;
            playerProp.changePlayer = true;
        }

        if (transV == 0 && transH >= 0.001f)
        {
            playerProp.playerState = PlayerProperties.PlayerState.Right;
            playerProp.changePlayer = true;
        }

        if (transV >= 0.001f && transH >= 0.001f)
        {
            playerProp.playerState = PlayerProperties.PlayerState.UpRight;
        }
    }

    void FixedUpdate()
    {
        transV = Input.GetAxis("Vertical") * speed * Time.deltaTime;
        transH = Input.GetAxis("Horizontal") * speed * Time.deltaTime;

        transform.Translate(transH, transV, 0);
    }

The reason for this is Input.GetAxis. It smoothes out the input from the keys. Try Debug.Log(Input.GetAxis); in Update to see what I mean.

To avoid this you can use Input.GetAxisRaw instead. This will return 1 iff the possitive button is pressed -1 iff the negative button is pressed and 0 iff neither is pressed.

Also you shouldn’t handle the input in FixedUpdate if you have the rest of your calculation in Update. Fixed Update is used for physics.
