How to save text from input fields in a variable?

Unity Engine
1

I’m trying to create an input field where the player enters their name and the name is then saved into a variable. I have a canvas setup with an input field, the input field will run a function OnString_PlayerName when the editing is done:

// Player name
private string playerName = "";

// This is run by the input field when done editing
public void OnString_PlayerName()
    {   
        // newPlayer already declared early on
        // setPlayerName stores the player name in another script
        newPlayer.setPlayerName = playerName;
    }

I don’t know how to set the input field to store the text into the playerName variable. Could someone help?

    public void OnString_PlayerName(string value)
    { 
        newPlayer.setPlayerName = value;
    }

Then you can create a new entry on the “End Edit” Event on the input field and choose the OnString_PlayerName function in the drop down . Make sure to assign the gamobject on that the OnString_PlayerName script is living on to the object field.

I tried using the code provided, but nothing is saved to the variable. I did all the steps you listed, but what I don’t understand is why pass an argument into OnString_PlayerName? Do I need the private playerName variable?

Are you quite sure you set it up correctly? fffMalzbier’s answer was correct.

In the inspector of my inputfield, the OnString function has another input field underneath the dropdown menu. The example you supplied doesn’t have such a field in the inspector. Is this normal?

There are 2 types of parameter for the event structur: Dynamic and Static.
Static is what you have currently. You can give a fixed input to the function you are calling.
The dynamic gives you automatically the string that was input into the Input field.

Oh, there are two possible structures. I didn’t see that anywhere in the manual (or I probably looked in the wrong place). It would have been nice to see that there.

How would I use this for an Int?

int x = 0;

if (Int32.TryParse(Label.Text, out x))
{
    // you know that the parsing attempt
    // was successful
}

For anyone else trying to figure this one out, the dynamic and static events are set in the drop down when selecting the function name.
