How to access a Component from another Child when current is Destroyed
My Character(ParentObject) has 2 sprites/skins(dresses or whatever you wanna call it) that you can select from the menu(Children). Those 2 gameObjects(sprites) are stored in a list, whenever I select a skin from the menu, it Instantiate the selected sprite and destroys the current one(they Instantiate inside Character GameObject). Each Sprite has a Animator.
public class Character : MonoBehaviour {
bool move = false;
Animator animator;
void Start() {
animator = transform.GetComponentInChildren<Animator>();
}
void Update(){
if (Input.GetKeyDown (KeyCode.Space) || Input.GetMouseButtonDown (0)) {
move = true;
}
}
void FixedUpdate() {
if (move == true) {
animator.SetTrigger ("Moved");
}
When the first sprite is destroyed, I get the error "The Object Type Animator has been destroyed but you are still trying to access it". I thought that if the first sprite was destroyed, the code (animator = transform.GetComponentInChildren();) would get the second Sprite Animator. But isn't working that way. How do I get the Animator from the second sprite when the first is destroyed.
P.D. : The 2 Sprites have NO script. Character Object has the script Character.
Likely you will need to call this line again when a component is destroyed:
animator = transform.GetComponentInChildren<Animator>();
Given the structure of your code, it may be simpler to just call it every frame.
The effect is part of the way the scripting language works. When you store the animator you store a reference to the specific instance of the animator component in memory, not the general animator on the childe object.
To fix you could simply grab a reference to the animator in the update loop
void Update (){
animator = transform.GetComponentInChildren<Animator>();
//do other stuff with animator
}
But getting a reference is expensive. This method will cost you in terms of performance.
A better way to do it as follows 1. First check if the animator component is not null. 2. If the animator component is null then get a new reference to the animator
void Update (){
if (!animator){
animator = transform.GetComponentInChildren<Animator>();
}
//do other stuff with animator
}
Its typically a good practice to check if a reference is null every time you refer to a object that might be destroyed.
