I’m trying to figure out how to make a sprite above my player character appear and disappear when I need it to in C# script. I tried looking up the functions used with SpriteRenderer but none of them seemed to be what I needed. I though I could use the variable isVisible but it’s read-only.
Is that the same thing, or does it have other consequences? Also, what function would I use to do that in a script?

The consequences of disabling a gameObject is that it component on it won’t work on it in the game until you make it active again.
If you want the gameObject to still be active and it script and comonent to still work while it invisble ,just turn invisible, in your class put this code
Easy way
public/private SpriteRenderer sr;
public/private bool visible=true/false;
void Start(){
sr=gameObject.GetComponent();
}
void Update(){
if(visible==true){
sr.enabled=true;
}
if(visible==false){
sr.enabled=false;
}
}
Hard way(if you still want to use the sprite renderer in a way);
public/private SpriteRenderer sr;
public/private bool visible=true/false;
void Start(){
sr=gameObject.GetComponent();
}
void Update(){
if(visible==true){
sr.material.color=new Color(sr.material.color.r,sr.material.color.g,sr.material.color.b,255);
}
if(visible==false){
sr.material.color=new Color(sr.material.color.r,sr.material.color.g,sr.material.color.b,0);
}
}
This only check if it visible and set the sprite to be visible or invisible, you would have to make changing the visible variable part depend on how it will work
Hope this help even if you don’t need it.

Hi Luigi 🙂 I’m afraid that your script won’t work properly, it will check every frame too see if the “var visible” is true or false and it would proceed to change it. You will end up with a nice loop hehe.
Although is true that disabling a GameObject will disable its components too, you shouldn’t put important components on a item that will disappear and reappear.

alternate way to MegaLuigi’s first one
SpriteRenderer theSprite;
void Start()
{
theSprite = gameobject.GetComponent<SpriteRenderer>();
}
void Update ()
{
if(Input.GetButtonDown("Fire1"))
{
if(theSprite.ActiveSelf)
{
theSprite.SetActive(false);
}
else
{
theSprite.SetActive(true);
}
}
}
if you left click, it’ll toggle sprite visibility
