What can i write to component in function.

Hi,
what can i write for component when i create a function?

Example

Public void test (.... ex)
{
gameObject. GetComponent<ex>() ;
}

Instead of .... ????

When i was write Component instead of... I taking a mistake.

'ex' is a variable but is use like type.

What can i do about this situation?

 

It's unclear what you are trying to do exactly. Maybe you are trying to create a generic method that takes a type? Is this what you are looking for? Sorry your English is difficult to understand.

Code (CSharp):

1. public void test<T>() where T : Component
2. {
3.   gameObject.GetComponent<T>() ;
4. }

 

praetor can u help me understand how to use this where to generic method

 

Well this method doesn't really do anything. I have no idea what the OP is actually trying to accomplish. I guess one possibility would be something like this:

Code (CSharp):

1. public bool HasComponent<T>() where T : Component {
2.   T behaviour = GetComponent<T>();
3.   return behaviour != null;
4. }

Then elsewhere in your code you could check for the existence of a type of component:

Code (CSharp):

1. if (HasComponent<Collider>()) {
2.   // do something
3. }

You could probably achieve something more useful with a more concrete subtype like Behaviour which would let you enable/disable something, or some custom type.

 

Sorry about that.
I have writed my phone.

I want to explain again.

Example you have got a simple function.

Public void test(string k) {
Debug. Log(k);
}

If you want to call this function you write test("hello my name is " ) ;


Well if my function is

Public void test ( ???) {

gameObject. GetComponent<test>() ;



}

Test(????)

 

thnks i will google concrete subtypes

 

your function doesn't do anything. we need to know what you're trying to get from the function.
this function takes a gameobject and checks if it has a script attached

run it with
test(cube_gameobject);

Code (CSharp):

1. Public void test (GameObject obj) {
2.     if(obj.gameObject.GetComponent<somescript>() )
3.     {
4.         Debug.Log("the object has the script");
5.     }else
6.     {
7.         Debug.Log("script not found");
8.     }
9.  
10. }

 

Johne5, what i can write instead of ???.

 

you could put this.gameObject
so
test(this.gameObject);

or if you have public gameObject, you can use that.

public GameObject testObject;

test(testObject);

 

So;
Public void test(GameObject ex) // what can i write instead of GameObject
{
gameObject. GetComponent<ex>();
}

Test(b); // b is public gameobject

Sorry, it is not working.

 

Error is
Ex is a variable but is used like a type.

 

If you want a "dynamic" thing to put into GetComponent you have to do it like my example:

Code (CSharp):

1. public void test<T>() where T : Component
2. {
3.   gameObject.GetComponent<T>() ;
4. }

Then you can call it with whatever type you want. For example:

Code (CSharp):

1. test<Collider>();

 

You're giving us enough info about what you're trying to do.
it's failing because of this line
gameObject.GetComponent<ex>();
This does nothing. it's an incomplete statement. you're getting a conponent and not doing anything with it.
and it should be use like this.
ex.GetComponent<Transform>(); or what ever class you're looking for

GameObject can be any class.
like
Public void test(Text ex)
Public void test(Animator ex)
Public void test(Renderer ex)
Public void test(Transform ex)
Public void test(String ex)
Public void test(Int ex)
Public void test(Float ex)

 

My real function;

Public void levelLov(Trabsform childA, string geciciString,........ diz) // what can i write instead of.....?
{
foreach (Transform child in childA)
{
if (child.name! =geciciString & & child. gameObject. GetComponent<diz>())
{k=k+1;animArr[k]=child;}
}
etc.

So, preatorblue Your codes is not proper to my codes.

 

I hope this will help

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. public class TestApp : MonoBehaviour
4. {
5.  
6.     public GameObject ex;
7.     private Transform tx;
8.     void Start()
9.     {
10.         test1(ex);
11.         test2("New Name For Object");
12.     }
13.     void Update()
14.     {
15.  
16.     }
17.    
18.     void test1 (Gameobject obj)
19.     {
20.         tx = obj.GetComponent<Transform>();
21.     }
22.    
23.     void test2 (string str)
24.     {
25.         ex.gameObject.name = str;
26.     }
27.  
28. }

 

Johne5 I know you are right but unity3d give an error when i did your say

 

So the answer is lots of things.
but from your code it looks like you might be trying to set an animation

Code (CSharp):

1. Public void levelLov(Trabsform childA, string geciciString, Animator diz)
2. {
3.     foreach (Transform child in childA)
4.     {
5.         if (child.name! = geciciString & & child.gameObject.GetComponent<diz>())
6.         {
7.             k=k+1;animArr[k]=child;
8.         }
9.     }
10. }

the line of code is looking for a script to be attached to the child objects. So, can you tell me the name of a script that is attached to a child object?

 

@PraetorBlue's solution can work here. What you probably want to do is this:

Code (CSharp):

1. public void LevelLov<T>(Transform child, string geciciString) where T : Component
2. {
3.    foreach (Transform child in childA)
4.    {
5.       if (child.name != geciciString && child.gameObject.GetComponent<T>() != null)
6.       {
7.          k=k+1;
8.          animArr[k]=child;
9.       }
10.    }
11. }

 

Unfortunately same error johne5


'diz' is a variable but is used like a type.

 

I think you might have a typo.
Public void levelLov(Trabsform childA, string geciciString, Animator diz)
should be
Public void levelLov(Transform childA, string geciciString, Animator diz)

 

No no it is a phone mistake johne5 code is right.

PraetorBlue and vryken, i am trying your suggestion.

 

can you tell us what script you're looking for in child objects?
Does it change all the time? then try PraetorBlue's code.

 

Well, how can i call this function?
levelLov(tempTransform, tempString,....)

 

it sounds like you don't know what diz is used for, so i removed it. give this a try

Code (CSharp):

1. Public void levelLov(Trabsform childA, string geciciString)
2. {
3.     foreach (Transform child in childA)
4.     {
5.         if (child.name! = geciciString)
6.         {
7.             k=k+1;
8.             animArr[k]=child;
9.         }
10.     }
11. }

call it with
levelLov(tempTransform, tempString)

 

Johne5, there is a lot of objects in my scene and they have some components thats I write. Example A1 B1 etc.. (400-500 pieces)

This function will make different animations based on the component on the object.

 

ok, so go with something like this

Code (CSharp):

1. public void LevelLov<T>(Transform child, string geciciString) where T : Component
2. {
3.    foreach (Transform child in childA)
4.    {
5.       if (child.name != geciciString && child.gameObject.GetComponent<T>() != null)
6.       {
7.          k=k+1;
8.          animArr[k]=child;
9.       }
10.    }
11. }
12.  
13. call it with
14. levelLov<B1>(tempTransform, tempString);

 

PraetorBlue and

Your code is not giving an error but how can i call this function with 3 arguments

 

Add a third argument to the function, whatever that may be.

 

Finally, it is working. You're amazing.
Thank you for your answer.
PraetorBlue, Johne5, Vryken

You are my hero this month

Thanks alot really
