How to use inputfield with a button and text?

It's pretty easy, you need a script that has a reference to the InputField and the Text, and a function that takes the text from the input and set it as the text of the Text when called. Then, setup that function to be called when the button is pressed.

The script should look similar to t$$anonymous$$s: using UnityEngine; using UnityEngine.UI;

 public class InputFieldToText : MonoBehaviour {
     public InputField Field;
     public Text TextBox;
 
     public void CopyText() {
         TextBox.text = Field.text;
     }
 }

Now:

1. Create a Button, an InputField and a Text

2. Add that InputFieldToText script to any object, select that object and drag and drop the InputField and the Text in the proper slots for that script.

3. Select the Button and look at the inspector, there's a Box at the bottom to add functions that should be called when the button is clicked.

4. Press the "+" button at the bottom right of that box, it'll add a new line.

5. Drag and drop the game object that has the InputFieldToText component into the box where it says "(None) Object", it will enable the drop down button next to it.

6. Click in that dropdown, look for the InputFieldToText entry in that list and select it.

7. It will display another menu with valid functions you can call from that script, select the CopyText function.

That's it, run the game, type some text in the input field and press the button.

Also, if you can't find tutorials explaining how to use somet$$anonymous$$ng there's always the API documentation. You can see there that the InputField and the Text classes both have a "text" property.
