Syntax troubles (GetComponent and changing variables)
Hello. It seems a lot of other people have trouble accessing and changing variables in other scripts/components however I've managed to make myself a problem that the other answers I've read weren't about to address.
I have a bool I want to change that lies on a different script. Both the script making the change and the script containing the changing variable lie on the same gameObject.
Can someone point out what I'm doing wrong? I'm working in C#
var go = this.gameObject;
go.GetComponent("PlayerStateSync").moving = false;
That tells me UnityEngine.Component doesn't contain a definition for the "moving" bool I'm trying to reference.
var go = this.gameObject;
var com = go.GetComponent("PlayerStateSync");
go.com.working = false:
That tells me UnityEngine.GameObject can't find a definition for the bool.
Try this instead
var go = this.gameObject;
var com = go.GetComponent<PlayerStateSync>();
com.working = false;
Or if you want to be really fancy
GetComponent<PlayerStateSync>().working = false;
This assumes that PlayerStateSync is a subclass of MonoBehaviour.
What? Really?
Why does that work? It looks almost exactly the same as my attempt!
There are three different version of GetComponent(). The version that you've used GetComponent("PlayerStateSync") will return an object of type Component, which you'd then have to cast into an instance of PlayerStateSync,
var com = GetComponent("PlayerStateSync") as PlayerStateSync;
If you want to avoid having to perform the casting operation, then you can use the generic version of GetComponent()
var com = go.GetComponent<PlayerStateSync>();
These two version are identical, it's just that the second option is a bit cleaner and more readable.
Ahhhh ok. Yes I see it in the documentation now that you've explained it.
function GetComponent. () : T function GetComponent (type : String) : Component
It's not apparent to me what those mean so I've just been glossing over it <- noob.
So now I can better read an API reference, thanks!
