Check If GameObject Has Render Component
Hi,
I'm trying to turn off all my renderers on my object, and all their child's. So what I'm doing is getting all the components in the gameObect in a for loop and using a renderer.enabled = false. But sometimes the game object might not have an renderer, and it will throw an error.
How would I do an if statement to check firstly if it has a renderer, then shut it off:
var components = GetComponents(Component);
for(var c : Component in components){
if(Renderer)
c.renderer.enabled = false;
}
You're close.
It doesn't really make sense to get all of the components, if you're just looking for renderers -- a renderer is a component.
You could do something like this:
for ( var r : Renderer in GetComponents(Renderer) )
{
r.enabled = false;
}
This can potentially cause a compiler warning about implicit downcasts, which you can avoid by adding #pragma downcast to your script, or treating r as a Component which you always cast to a Renderer.
If you want to search an entire GameObject and its children, you could use GetComponentsInChildren() instead.
In Unity, testing the reference to a component or game object returns true when the component exists, and false if not:
var components = GetComponents(Component);
for(var c : Component in components){
if(c.renderer)
c.renderer.enabled = false;
}
