Input Lag in Animation Script
In the Editor and after building the game on Very-Low Quality (although I can easily run max quality), whenever I press a button, it takes maybe 300ms to actually register the input. And when I tap semi-quick my sprite moves but doesn't animate.
I'm pretty new and am tired of looking for so long so I posted here. The problem seems to be that it's taking a while for my animator to receive the boolean (double-checked in animator window).
Oh, and not to forget, my movement script is not affected by this problem although it also uses Input.GetAxis. However, it is a one-liner.
public class RunningAnimation : MonoBehaviour
{
public bool isRunning;
public Animator anim;
bool flipX;
// Start is called before the first frame update
void Start()
{
anim = GetComponent<Animator>();
}
// Update is called once per frame
void Update()
{
float moveDirection = Input.GetAxis("Horizontal");
switch (moveDirection)
{
case 0:
isRunning = false;
break;
case 1:
isRunning = true;
flipX = false;
break;
case -1:
isRunning = true;
flipX = true;
break;
}
anim.SetBool("isRunning", isRunning);
this.gameObject.GetComponent<SpriteRenderer>().flipX = flipX;
}
}
Input.GetAxis returns a value between -1 and 1. As you hold a key on your keyboard, the value increases up to 1, using smoothing, to produce natural movement. The issue here is, your switch statement only works when the cases are 0, 1 and -1. As I said, it returns a value between -1 and 1 and does take some time to get there. The input lag isn't the problem, but how you are reading the value.
I suggest doing some rounding to get the input immediately, for example, right before your switch statement, you could write:
float moveDirection = Input.GetAxis("Horizontal");
// Rounds values to -1, 0 or 1
if (moveDirection > 0)
moveDirection = 1;
else if (moveDirection < 0)
moveDirection = -1;
WHAAT?? It's interpolated??? I would have not thought at all. Well, of course now I'm realizing that's probably for people using controllers. Anyway, whatever. Works like a charm! Thank you!
You can also use Input.GetAxisRaw() if you do not want any interpolation.
Well, it's been over a year so I know that now, but I guess that will be useful for any noobs who see this in the future.
Also, using GetAxisRaw() worked much better for most projects. Thank you for pointing it out
