Problem with a prefab, the public values dont reset when I start the game.

I need to access to a script called "Movement", and this script is in a prefab of an asteroid. inside the script I have a public variable, "velocity" for control the velocity of the asteroids.
ok, then I have an empty object, with a script with the game logic. I need to acces Movement script, for change the variable "velocity

Code (CSharp):

1.  public GameObject asteroid;
2. Movement movement;
3. void Start()
4. {
5. movement = asteroid.GetComponent<Movement>();
6. }
7. ...
8. Void level2()
9. {
10. movement.velocity+=5;
11. }

in theory, in the game the variables change, but then, when the procces stops, the value should be the original, but isnt... And change the prefab. What I do wrong?

Thanks for the help.

You are writing to the prefab directly.... don't you want to instantiate a gameobject from the prefab so it exists in the scene, then write to the values of the instantiated gameObject.

 

And how can I do that?

 

The second example here is pretty much what you're after: http://docs.unity3d.com/ScriptReference/Object.Instantiate.html

 

Dont works, with the second method creates an object, not a GameObject, and cant get component "movement" por change it,

Im ggetting mad, with my prefabs intances (the normal method) in the game I create gameobjects, with the name of the prefab and the " (clone) ", but, later, get component, change values, and modify the prefab instead only the clones in the game..... I dont know...

 

I'm not really sure what problem you're experiencing, to be honest.

If you want to create a version of a prefab in the scene and then change it's values, then you need to Instantiate a copy of it and change the values of that copy.

Code (CSharp):

1. public GameObject asteroid;
2. Movement movement;
3. void Start()
4. {
5. GameObject asteroidInstance = Instantiate(asteroid) as GameObject; // Creates an instance of your prefab in the scene
6. movement = asteroidInstance.GetComponent<Movement>(); // Gets a reference to this instance's Movement script
7. }
8. ...
9. Void level2()
10. {
11. movement.velocity+=5; // Adjusts the velocity value on this instance
12. }

That's assuming you only want one instance of the asteroid to be referenced via this script. I suspect you'll have issues with your current code, depending on what you're trying to achieve, though.
