Clones of Prefabs problem

Hello everyone, In some specific time periods, I want to speed up the steam of my prefabs which goes from left side of the screen to the righ side. And ı’m applying a force with the “Rigidbody.addforce” But ı want to apply this speeding up both to the prefabs which has already been produced and to the new ones which will be produced. Otherwise its being a syncronisation problem in the screen. Do you guys know how can ı do this?

 

Why not to store current force and then asign it on instantiating.

 

You could use a static speed variable in their script, then just increase the value and all gameObjects using the script will be able to use the value in their Update() methods.

 

how can i change speed of prefabs previously created

 

If you store a list or arraylist of all active objects then you can just loop through them adjusting their speed.

 

Yep. You could likely use a listener for changes in speed as well. Not sure which is faster.

 

.Does prefabs automaticlly removed from arraylist when destroyed. Or can i scripting manuelly for this?

and is there anyway to reach all clones which were already created without using arraylist?

 

OK once you have instantiated a prefab it's a gameObject. You can use a script on the gameObject that uses the OnDestory() method to remove it from the arraylist.

http://docs.unity3d.com/ScriptReference/MonoBehaviour.OnDestroy.html

If the cloned gameObjects all have the same script on them then you can use the static speed variable I mentioned before.

 

thank you too much for your answers, i understood which way i must follow. But i really hate to use arraylist. So is there anyway to reach all clones which were already created without using arraylist?

 

You can do a GameObject.Find or have them subscribe to an event listener thing.

 

i have no idea how event listenig is working? and i didnt find this from scripting reference :/

 

GameObject.Find (probably find by tag?) is likely the easiest.
