Question

What I’m trying to do is create a method that allows a user to search through a list of GameComponents to find a GameComponent of whatever class they passed in.

I’m at a total loss on how to do this. Any Ideas?

This is what I’ve tried so far. I’ve tried a lot of different ways to do it but I keep getting classDude cannot be resolved to a type. Thanks in advance.

public GameComponent<?> getComponentOfType(Class<Object> classDude)
    {

        for(GameComponent<?> gC : mComponentList)
        {
            if(gC instanceof classDude)
            {

            }
        }

    }

It sounds like you want:

public <T extends GameComponent<?>> T getComponentOfType(Class<T> classDude)
{
    for(GameComponent<?> gC : components)
    {
        if(classDude.isInstance(gC))
        {
            return classDude.cast(gC);
        }
    }
    return null;
}

Or without making it generic:

public GameComponent<?> getComponentOfType(Class<?> classDude)
{
    for(GameComponent<?> gC : components)
    {
        if(classDude.isInstance(gC))
        {
            return (GameComponent<?>) classDude.cast(gC);
        }
    }
    return null;
}

In other words, what you were missing were the Class.isInstance and Class.cast methods.
