Does Unity has a common interface for generic type casting?

Hello All,

I would like to ask, that is there any interface or other way to solve for Unity to achieve generic type casting successfully?

I got failed casting for it ( Cannot convert type 'UnityEngine.Object' to 'T' ):

Code (csharp):

1.         public T LoadExternal(string objectName)
2.         {
3.             Object instance = Instantiate((Resources.Load(objectName, typeof(T))));
4.  
5.             return (T)instance;
6.         }

Thank you!

 

That's not the correct syntax to create a generic method.

Do you need to add a constraint?

Code (csharp):

1.  
2. class YourClass<T> where T : UnityEngine.Object // <-- Constraint
3. {
4.   ...
5.  
6.   public T LoadExternal(string objectName)
7.   {
8.     Object instance = Instantiate((Resources.Load(objectName, typeof(T))));
9.     return (T)instance;
10.   }
11. }
12.  

 

Thank you, that's what I'm looking for!

 

You need to add <T> to your method declaration:

Code (csharp):

1.  
2. public T LoadExternal<T>(string objectName)
3. {
4.     Object instance = Instantiate((Resources.Load(objectName, typeof(T))));
5.     return (T)instance;
6. }
