Hello, I am fairly new to Unity and coding so excuse me if I sound out of touch. I am making this 2D platformer/sidescroller and I have this sprite for dust trails for when he runs/jumps and since I don’t know how to implement them via the particle system I figured I would create a new game object, attach the dust animations to it, attach it to my character as a child and trigger it via script whenever I run/jump. However, when I set up all the animations and trigger them the game freezes on the very first frame of said animation and I get the following error in the console.
NullReferenceException: Object reference not set to an instance of an object dust.Update () (at Assets/dust.cs:18)
I created an entirely new project with minimal code just to see if it was one of the other scripts affecting it but sadly no. Here’s the new test code that I used for the character (just a jump script basically)
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class jump : MonoBehaviour {
public Rigidbody2D rb;
void Start () {
rb = GetComponent<Rigidbody2D>();
}
void Update () {
if (Input.GetKeyDown(KeyCode.Space))
rb.AddForce(new Vector2(0, 300));
}
void FixedUpdate()
{
rb.velocity = new Vector2(0, rb.velocity.y);
}
}
And here’s the script for the game object I attached the dust animations to -
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class dust : MonoBehaviour {
Animator anim;
jump skok;
// Use this for initialization
void Start () {
anim = GetComponent<Animator>();
skok = GetComponent<jump>();
}
// Update is called once per frame
void Update () {
if (skok.rb.velocity.y > 0)
anim.SetTrigger("go");
}
}
The weird part is the game only freezes if the animation is in any way triggered. I can let the animation loop as I’m playing and there’s no problem whatsoever, but once I trigger it via code the I get this error and the game just freezes.
Honestly I’m sorry if it’s a dumb question, as I said I’m only a week or so into Unity and C#, thanks in advance.
