Hi to everyone how can i do this that for example i have 2 gameobjects one is cube and the other capsule and they both have two simple scripts so how can i attach the script of cube to a capsule and also with all of the values.
The most simple way:
- Place this in the script of the Object 1:
[SerializeField]
private YourScript2 yourScript2;
- Attach the script reference from Object 2 to this field in Editor of Object 1.
- Now you can access from Object 1 to Object 2.
can you give me the code with fully explained
This is really all the code you need. What exactly do you not understand?
Next, you can access to Object 2 script like this:
yourScript2.FunctionTest();
I mean that i want to attach the script of the first gameobject to another gameobject through c#
for what purpose?

I am practicing on a project so this point has came so i thought that ask online about this because i do not know about this
Since you are not providing the target task for what purpose you need it, I can only guess.
Some thoughts:
- Cashing is recommended for such task. I described it above.
- You can also access via static mechanics like Singleton design pattern, and so on.
- You can also you Unity - Scripting API: GameObject.Find and then use Unity - Scripting API: GameObject.GetComponent in code to achieve your goal, but this is not recommended when you are dealing with many objects due to performance issues.
You would make it easier for me to answer if you clarified the task.
Generalizing Makaka’s response:
Referencing GameObjects, Scripts, variables, fields, methods (anything non-static) in other script instances or GameObjects:
It isn’t always the best idea for everything to access everything else all over the place. For instance, it is BAD for the player to reach into an enemy and reduce his health.
Instead there should be a function you call on the enemy to reduce his health. All the same rules apply for the above steps: the function must be public AND you need a reference to the class instance.
That way the enemy (and only the enemy) has code to reduce his health and simultaneously do anything else, such as kill him or make him reel from the impact, and all that code is centralized in one place.
Sorry to both of you the one gameobject is prefab and i want to attach the script to the prefab when it is cloning with values and i want to get that script from another gameobject that is already in the scene not a prefab.
To be clear, what you’re asking is how do you copy a component from one game object to another?
No i have two gameobjects one is prefab and the other one is the gameobject that is already in the scene and that have a script that has multiple variables of gameojbect int float and others and i want to attach it to the prefab when it is instatiating how can i do this
Well GameObject.AddComponent<T> is how you attach components to game objects at runtime: Unity - Scripting API: GameObject.AddComponent
So you just get the return on Object.Instantiate, then add your component, and assign values to it as necessary.
