Calling 1 script from another

Unity Engine
1

I have script #1 (store) which is working perfectly UNTIL I try to call script #2 (saver)

Maybe I am not thing this through correctly but When the player is leaving the store all I want to do is save the user info. As this info will be saved in other areas as well as when they exit I don’t want to put the 200 lines in each script. All I want to do is call Saver when the user clicks on the “leave store” button.

		if(GUI.Button(new Rect(30,70,140,25),"Leave Store"))
			{
			Saver.Start(); //Here is where I want it to call the Saver.cs
			Application.LoadLevel(TownScene);
			}

This gives me

as an error. What am I missing?

Thanks in advance

PS Both Scripts are added to the same Object (Store).

gameObject.GetComponent<Saver>().doSomething;

use this to get the script, then call a function after the last “.” or use a variable or whatever you want. Those need be public elements, else you can’t access them. Also the “Start()” function will be run when the game starts/the object appears in the game, so there shouldn’t be a need to re-call it, use a custom function with the needed stuff instead.

Like:

void Start()
{
   SaveGame();
}

void SaveGame()
{
   //do your save actions here and then call "SaveGame()" from other scripts
}

It is working now.

Thanks for the help.

My “saver” works perfectly. However now I want to call it from another scene.

If I put : gameObject.GetComponent(). to where I want to do another save in another scene I get: NullReferenceException: Object reference not set to an instance of an object.

If I add it to the scene I get an error on the server of : Could’t invoke RPC function ‘Saver’ because the networkView ‘SceneID: 2 Level Prefix: 0’ doesn’t exist.

I am probably missing something simple.

Any help would be appreciated.

When you load up the new scene are you saving or re-instantiating the object that the saver script is attached to?
if you are and you do not want to try using

DontDestroyOnLoad(transform.gameObject);

On the script/gameobject you want to carry from scene to scene.
Also

gameObject.GetComponent<Saver>();

Only works if you are trying to make that call from a script that is attatched to the same game object
If you are trying to call on Script:Saver attatched to GameObject: MainCamera
From a script attached to a random Cube in your game you would get that error.

But you can do it with something like this:

private Global glob;

void Start (){
GameObject shandler = GameObject.Find("ScriptHandler");
glob = shandler.GetComponent<Global>();
}
void Update(){
glob.frames = glob.frames + 1;
}

What that does is declares the variable glob as a private variable of Global (bad example the script i am looking for is named Global.cs)

then when void Start is run it finds the gameobject ScriptHandler and then sets glob = the component script Global.
Which allows me to access any public vars/functions with glob.dosomething() or glob.varname

And for anybody who is nitpicky

void Update(){
	GameObject.Find("ScriptHandler").GetComponent<Global>().frames = GameObject.Find("ScriptHandler").GetComponent<Global>().frames + 1;

}

Would accomplish the same thing
