How to use the "On Value Change" in Unity3D Input Field UI component

Question

I'm following a tutorial on how to work with Unity3d and I've hit a dead end.

I believe something changed in a newer version of Unity since the tutorial seems to work nice the way I'm doing it.

I have an Input Field UI component that I want to call a C# function every time I change it.

According to the tutorial I just have to use the "On Value Change" property of the Input Field (script) and tell it to call some function that takes a string as an argument.

public string playerName;
public void setName (string name)
{
    playerName = name;
    Debug.Log("Set playerName: "+name, gameObject);
    Debug.Log("Get playerName: "+playerName, gameObject);

}

Yet, this does nothing, my playerName property it's always empty and I don't receive anything in name.

How do I go about doing this? I've seen an answer setting up a listener in the Start() function, and then using an UnityEvent in here: Get text from Input field

But is there another way to do this using the Unity3d graphical editor that doesn't involve writing so much code?

Answer 1

Yes you can add event handlers via the inspector. Select the InputField game object and scroll down to the bottom of the InputField section in the inspector. Click + to add a new event handler then select the receiving game object and method you want to call.

Use the Dynamic string version of the function to pass the input string as a parameter. The Static Parameters callbacks let you set the function parameter in the inspector, which likely isn't what you want when responding to InputField changes.
