Thanks a lot! Your video helped immensely where the Unity Docs did not, particularly for the difference between the OnValueChanged and OnEndEdit events, and their ties (or not) to scripts!. And the comment by @Lorenzo Bergamini and your reply (about making sure to use the upper elements of the list that are Dynamic, which you stated at 2:23, but which I also missed when initially watching the video. Doh!) was spot on! Well done!
Excellent video! I struggled to understand how to compare 2 fields (Password and Confirm Password) text string fields, and this tutorial got me exactly where I needed to be. THANK YOU!
My problem is if i use input field for entering in messages for a chat, the text goes outside of the background input field and I have moved the text and it doesn't resolve the issue.
i have a problem, this worked for me but after i tweaked some stuff it suddenly didnt work and i dont know why. When i type into the input, the debug log will slow empty, but there is stuff in my input when i go back. that means the string isnt working right? something wrong with my ReadStringInput? but idk why it worked before then stopped, its same as ur code
Nice explanation, but it doesn't work form me :( A text box appears in the inspector (in the OnEndEdit box) and in the console is shown what I write in the inspector, instead of what a I wirte in the InputField. Do you know why?
Probably you selected the static function in the OnValueChanged or the OnEndEdit event, for the static function you have to write the string in the inspector to execute the function and always is executed with that same value. The dynamic function instead sends to the function the string that is written in the Input field
@@lorenzobergamini4657 I do it in 2:23, the upper elements of that list are the dynamic functions (note the tittle "Dynamic Strings"), while the elements below are the static functions, Our function is in both lists but in this case you have to select the one that is in the Dynamic Strings list
mmm there are several alternatives depending on ui design and target platform, if you are in a PC build maybe you want to display a message indicating that the input wasn't correct, maybe a GameObject in the canvas with a background panel, a text with the proper message and an OK Button that simply closes the message it self, for that in the On Click event of the button, click on plus, assign the parent of the message and in the drop down menu select "GameObject" - "SetActive(bool)" and uncheck the checkbox, this way when you press the button the panel closes. Once you have the message working, then work in the logic of the Input Field, suppose you have a script and inside you define a function that is going to be called on the "On End Edit" event from the Input field, something like this": public void InputFieldEnter(string s){ //The user entered a text and hits enter, "s" is the entered text } Connect this function to the Input field, similar to the button, in the On End Edit event from the InputField, click on plus, drag the GameObject that has the script with the function and select it using the drop down menu (make sure you use the function listed on "Dynamic", that way the value send to the function is the content of the input field). Now for the logic, if the input field is empty, display the message else proceed with the next part, something like this: public void InputFieldEnter(string s){ if(s == ""){ errorMessage.SetActive(true); }else{ // do whatever you want if the input is correct } } In the previous case "errorMessage" is a GameObject type variable that has to be defined below the "Start" method and you need to make sure tu drag the GameObject of the error message in the field in the inspector, you define the variable like this: public GameObject errorMessage; //Drag the error message in this field in the inspector So, in summary, if you solve the problem this way, when you enters a null value in the input field, the message will appear, you click OK and enters the text again.
this only works if you have 1 input, what if you have multiple inputs and want to reuse the ReadStringInput functions? how does the code know which input to update?
yes, but you need to define the reference for an InputField component in your script, you can do it this defining a variable above the Start method for example: public InputField theInputFieldIWantToClear; If the prevous line gives you an error, prabably you need to import the proper namespace, above all add: using UnityEngine.UI; Then itˋs very important to initialize that variable with the component you want to clear, if you don´t do this step you´ll get a null reference exception. A simple way to initialize the variable is assigning the GameObject with the InputField component to the field called "theInputFieldIWantToClear" in the inspector of your script. You have a video here: th-cam.com/video/ESwadW9Ttzg/w-d-xo.html Finally the clear part, for that you can do: theInputFieldIWantToClear.text = ""; You can add the previous line were you need to clear the input field, for example in the OnEndEdit function that executes the InputField

@@MoonLiteNite in the on end edit you have to look closely... there is a static area and a dynamic area.. both have the function in it. It seems you have selected the static one.
yes of course! mmm you can do it in different ways, for example, make each field execute it's own function inside the script (in the on end edit event of each input field), then add a button that executes another function that use the information entered.

About your problem, let's divide it in two parts. first saving and loading a string, you can find info about saving strings with player prefs here:
gamedevtraum.com/en/game-development/unity-tutorials-and-solutions/how-to-save-and-load-a-string-with-playerprefs-in-unity/
I suggest you create two functions, one to load and one to save, suppose you define a variable called "inputSavedData":
public string inputSavedData;
public void SaveData(){
PlayerPrefs.SetString(“aNameForYourData”,inputSavedData);
}
public void LoadData(){
inputSavedData = PlayerPrefs. GetString(“aNameForYourData”,””);
}
you can call LoadData in Start or Awake functions, like this:
void Start(){
LoadData();
}
And the saveData function you can call it where you read the input field, let's suppose you do that in a function called, InputFieldFunction:
public void InputFieldFunction(string inputText){
inputSavedData = inputText;
SaveData();
//do whatever you need
}
So up until here is the first part of the problem where you save the data and then recover it.
Now to write the saved text in the input field when loading, for that you'll need to define a reference for an InputField type component, first make sure you implement the UI namespace, above all the script add:
using UnityEngine.UI;
then above start you can define:
public InputField myInputField;
And then in Unity drag the InputField GameObject to the "myInputField" variable in the inspector of the script.
Once this is done you can write a text in the input field, so once you load the data, you can write the recover text to the input field:
void Start(){
LoadData();
myInputField.text = inputSavedData;
}
I hope you can solve your problem
bravo explained very well,
thnx
why do you put the main camera on the ui
Ohh that's because in this particular case the script that contains the function to be executed by the input field is assigned to the main camera
how do we take the text for put it somewhere
Is it working ? : input = textDisplay.GetCompenent().text;
The input variable is already the text, so you don't need to do anything else.
Thank you for your effort, that was very helpful. but what if I have two inputfields that I want to read and want to create a separate string for each inputfield? is that possible?
Yes of course, everything is possible :D
Just make two sepparate functions in your script and connect each input field to each function just how it's done in this video.
Inside the function you can make a boolean variable true indicating that the field was entered, and then check if the other input field is also entered and make things happen in that case. This could be an example:
//Here Begins C#
bool input1Ready=false;
bool input2Ready=false;
string input1Value;
string input2Value;
public void FunctionForInputField1(string textFromInput){
//Connect this function to one input field
input1Value=textFromInput;
input1Ready=true;
if(input1Ready && input2Ready){
//both inputs are entered, what should we do?
}
}
public void FunctionForInputField2(string textFromInput){
//Connect this function to another input field
input2Value=textFromInput;
input2Ready=true;
if(input1Ready && input2Ready){
//both inputs are entered, what should we do?
}
}
//Here Ends C#

Yep, the InputField sends a string to the selected function inside the script, then you have to convert it to int. For example this way:
int intValue = int.Parse(stringValue);
intValue can also be defined as a global variable.
