In my game I am displaying a textbox; I want it to disappear when i click the button. The code I have tried until now is:
private var isclick: boolean=true;
function OnGUI() {
if (isclick==true){
GUI.Label(new Rect(Screen.width/7,Screen.height/7,Screen.width,Screen.height),word);
words=word;
if (GUI.Button(Rect(Screen.width/5,(Screen.height/4)+320,Screen.width/2,Screen.height/12),"remove")){
isclick=false;
}
}
word is text which is displaying on screen. When I click the button the text has to disappear, but it doesn't.
As I can see you're having problem with indent and close bracers..
private var IsClicked : boolean = false;
function OnGUI() {
if(!IsCliked) DrawWordGUI();
}
function DrawWordGUI() {
words = GUI.Label(labelRect, words);
if(GUI.Button(buttonRect, "Remove")) {
IsClicked = true;
}
}

I have a "Start Game" button
public static bool GameIsStart;
public void changeCamera ()
{
if (GameIsStart == true)
return;
GameIsStart = true;
SceneManager.LoadScene ("Game");
}
}
``
There is a script that I added to the Prefabs
public GameObject [] gameobject;
private bool gameobject_IS_Spawn;
private float RandomPositionforX;
private int RandomObjects;
private void Update ()
{
if (StartGame.GameIsStart &&! gameobject_IS_Spawn)
{
StartCoroutine (Spawngameobject ());
gameobject_IS_Spawn = true;
}
}
IEnumerator Spawngameobject ()
{
while (true)
{
if (StartGame.GameIsStart)
{
yield return new WaitForSeconds (1.3f);
RandomPositionforX = Random.Range (-2.28f, 2.28f);
RandomObjects = Random.Range (0, gameobject.Length);
Instantiate (gameobject [RandomObjects], new Vector2 (RandomPositionforX, 24f), Quaternion.identity);
}
}
}
}
There is a button on the "Game" scene to access the preview
public void ChangeScene ()
{
SceneManager.LoadScene ("preview");
}
}
I click on the button, the "Preview" scene is loaded, but the "Start game" button does not work.
If I put in the "Preview" button SceneManager.LoadScene ("Game")
then I restart the scene ("Game") and everything works.
But if SceneManager.LoadScene ("Preview") but the buttons don't work.
When switching between scenes, is it necessary to stop Coroutine
How can this problem be corrected?
Without seeing the code it's a bit harder to find where the problem is coming from.
The only thing that is coming to my mind is that it may be something related with how the scene is stored and loaded after.
According to the Scene Manager Documentation, you could save the scene1 in a variable and keep the DontDestroyOnLoad(scene1) on its awake method, then add something like:
Scene scene2 = SceneManager.GetActiveScene(); SceneManager.LoadScene(scene1); To the button that reloads the previous scene.
In Unity 3D, when you select a button, it will stay pressed until you click outside the button and basically goes back to its Normal Color. The problem is, I want the button to stay pressed (color-wise) when I click outside the button or scene. Does anyone know how to keep a button pressed or "selected" after clicking it?
You can use Unity UI Toggle (as said by Muhammad). Change the design to remove the checkmark and make it looking like a button.
With this component you have the state 'isOn' that you can use and change the color when selected for example.
public class Button_Stay_Pressed : MonoBehaviour
{
private Button btn;
[SerializeField]
private Sprite normal_sprite;
[SerializeField]
private Sprite pressed_sprite;
void Awake()
{
btn = gameObject.GetComponent<Button>();
btn.image.sprite = normal_sprite;
btn.onClick.AddListener(TaskOnClick);
}
void TaskOnClick()
{
btn.image.sprite = pressed_sprite;
}
}
Here is the C# script using delegate that'll (toggle between buttons) set clicked button to "on/pressed" (custom) colour and change the other button(s) with this script attached to them to deselect colour, Copy & paste solution(attach this script to buttons you want to toggle between):
using TMPro;
using UnityEngine;
using UnityEngine.UI;
/// <summary>
/// Functionality: Control UI Button clicks selected colour
/// Author: Akrima Huzaifa
/// Date Created: 1st-December-2022
/// </summary>
public class BtnClickHandler : MonoBehaviour
{
public delegate void OnBtnClick(BtnClickHandler obj);
public static event OnBtnClick onBtnClick;
public Button poleBtn;
public Image poleImage;
private void Awake()
{
if (GetComponent<Button>())
{
poleBtn = GetComponent<Button>();
poleImage = GetComponent<Image>();
poleBtn.onClick.AddListener(delegate { OnBtnClick(); });
}
}
private void OnEnable()
{
onBtnClick += SelectDeselectBtn;
}
private void OnDisable()
{
onBtnClick -= SelectDeselectBtn;
}
public void SelectDeselectBtn(BtnClickHandler obj)
{
if (obj == this)
{
OnClick_ObjButtonSelected();
}
else
{
DeselectBtn();
}
}
public void OnBtnClick()
{
BtnClickHandler.onBtnClick.Invoke(this);
}
//---For UI---
public void OnClick_ObjButtonSelected()
{
if (!poleImage.fillCenter)
{
print("if color");
poleImage.fillCenter = true;
poleImage.color = new Color32(230, 230, 230, 255);
poleImage.transform.GetComponentInChildren<TextMeshProUGUI>().color = new Color32(255, 115, 0, 255);
}
else
{
DeselectBtn();
}
}
public void DeselectBtn()
{
print("else color");
poleImage.fillCenter = false;
poleImage.color = new Color32(178, 178, 178, 255);
poleImage.transform.GetComponentInChildren<TextMeshProUGUI>().color = new Color32(255, 255, 255, 255);
}
}
I am very new to Unity and I have trouble understanding on click possibilities with my UI buttons etc.. In my project, I have a button which changes its image whenever I click on it and the way I made it is: I created this script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
[RequireComponent(typeof(Button))]
public class OnClickScript : MonoBehaviour
{
public static int spritenumber=1;
public Button mybutton;
public Sprite square;
public Sprite circle;
public Sprite triangle;
public int counter = 1;
void Start()
{
mybutton = GetComponent<Button>();
}
public void changeButton()
{
if (PAUSESCRIPTE.isPaused == false)
{
counter++;
if (counter == 1)
{
mybutton.image.overrideSprite = square;
spritenumber = 1;
soundmanagerscript.PlaySound("buttonpress");
}
if (counter == 2)
{
mybutton.image.overrideSprite = circle;
spritenumber = 2;
soundmanagerscript.PlaySound("buttonpress");
}
if (counter == 3)
{
mybutton.image.overrideSprite = triangle;
spritenumber = 3;
counter = counter - 3;
soundmanagerscript.PlaySound("buttonpress");
}
}
}
}
I attached this script to my button, selected sprites which I want to use and I added on On Click() function to the button.
Afterwards I decided that I no longer want to change the sprite of my button by clicking on the button itself but rather by clicking anywhere on the screen. I tried using Input.GetMouseButtonDown(0) but got no results since I used it incorrectly. Any help on, how to achieve what I want, is very welcome. Thanks in advance.
Here's how I'd do it:
using UnityEngine.UI;
using UnityEngine;
public class ButtonScript : MonoBehaviour
{
// Public objects
public Sprite[] sprites;
//Private objects/variables
private Image buttonImage;
private int spriteIndex;
void Start()
{
buttonImage = GetComponent<Image>(); // Get the image component of your button
spriteIndex = 0; // Set the index to 0
buttonImage.sprite = sprites[spriteIndex]; // Set the image to the first image in your sprite array
}
void Update()
{
if (Input.GetMouseButtonDown(0))
{
spriteIndex++; // Increment the index
if (spriteIndex > sprites.Length - 1) // Ensure that you stay within the array size
{
spriteIndex = 0;
}
buttonImage.sprite = sprites[spriteIndex]; // Set the image
}
}
}
However, you need to change the image settings to:
Image Type: simple
Use Sprite Mesh: true
(maybe) Preserve aspect: true
As an answer to your comment above, I will suggest you to have a button in the background and your pause button above. Then, replace your Update() method with an event OnClick() as you did before.
Your pause button will catch the left click and your background button will not.
Be sure to tick Interactable in the Button component.
Then you can safly remove the Image component of your background button, if you don't need it.
What it means is you can create (or modify) a class for your pause button
using UnityEngine.EventSystems;
public class PauseButton : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler
{
public bool IsMouseOver = false;
public void OnPointerEnter(PointerEventData eventData)
{
IsMouseOver = true;
}
public void OnPointerExit(PointerEventData eventData)
{
IsMouseOver = false;
}
// --
// Your OnClick method
// --
}
Note: the using eventSystems.
Now you can use this bool value within a code like amengelbrecht send you.
I'll will copy and paste his code from his answer, and add the bool value based on the previous class above.
public class BackgroundButtonScript : MonoBehaviour
{
// Public objects
public Sprite[] sprites;
public PauseButton pauseButton;
//Private variables
private Image buttonImage;
private int spriteIndex;
private void Start()
{
buttonImage = GetComponent<Image>(); // Get the image component of your button
spriteIndex = 0; // Set the index to 0
buttonImage.sprite = sprites[spriteIndex]; // Set the image to the first image in your sprite array
}
private void Update()
{
if (Input.GetMouseButtonDown(0) && !pauseButton.IsMouseOver)
{
spriteIndex++; // Increment the index
if (spriteIndex > sprites.Length - 1) // Ensure that you stay within the array size
{
spriteIndex = 0;
}
buttonImage.sprite = sprites[spriteIndex]; // Set the image
}
}
}
This will allow you to click anywhere on your screen except if the mouse is over your pause button. In this case, OnClick from the pause button will be called.
Be careful
If your game is is pause and the user left click anywhere but the pause button, depends on how your pause works, the Update() method of BackgroundButtonScript will be called and can lead to if (Input.GetMouseButtonDown(0) && !pauseButton.IsMouseOver).
I imported a custom sprite from Photoshop, and its color was purple. I want it so that when the button is pressed, it changes color. When I used renderer.material.color = Color.cyan;, and once the button is pressed, I have no idea how to make the color of the button return back to normal.
I just noticed that my answer, at its core, is the same as Heisenbug's, but in UnityScript.
private var original : Color;
function Start ()
{
original = renderer.sharedMaterial.color;
}
function changeColor(newColor : Color)
{
renderer.material.color = newColor;
}
function resetColor()
{
changeColor(original);
}
This is how you use it:
changeColor(Color.black);
There is no built-in way to do that. You can, however, store the original color before modifying it and the reassign it back:
Color originalColor;
void Awake()
{
originalColor = renderer.sharedMaterial.color;
}
void ChangeColor(Color newColor)
{
renderer.material.color = newColor;
}
void ResetDefaultColor()
{
renderer.material.color = originalColor;
}
I am programatically showing the soft keyboard when a layout is loaded on a button click.
I am showing the softkeyboard only when the textfield has focus. It works fine. But when I call the same method at another place in the code(not a button click) then the soft keyboard does not show up. Below is my code. Please point out where I went wrong.
public void showNewView() {
setContentView(R.layout.activity_main);
this.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
isRegisterScreen = true;
final EditText text1 = (EditText) findViewById(R.id.label1);
final EditText text2 = (EditText) findViewById(R.id.label2);
final InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
text1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean hasFocus) {
if(hasFocus){
inputManager.showSoftInput(labelText, InputMethodManager.SHOW_IMPLICIT);
}else{
inputManager.hideSoftInputFromWindow(text1.getWindowToken(), 0);
}
}
});
text2.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean hasFocus) {
if(hasFocus){
inputManager.showSoftInput(text2, InputMethodManager.SHOW_IMPLICIT);
}else{
inputManager.hideSoftInputFromWindow(phoneText.getWindowToken(), 0);
}
}
});
text1.requestFocus();
}
