I'd like to have a button displayed on screen, and as long as it's held, the user would turn.
This is how I created the button, and how I tried marking when the button is held:
if (GUI.Button (new Rect (OffsetUI, Screen.height - OffsetUI * 7, OffsetUI * 6, OffsetUI * 6), "left")) {
playerScript.LeftButtonHeld = true;
}
else {
playerScript.LeftButtonHeld = false;
}
Unfortunately this doesn't seem to work. I believe the button gets into 'if' statement, whenever the button is clicked (on finger up).
How can I detect when a user is holding the button?
Instead of GUI.Button, you will want to use GUI.RepeatButton as shown here:

I have a ScrollRect to which I add content to. When it reaches the point where the content is longer than the ScrollRect (ie when the ScrollBar's value changes from 0), I want the ScrollRect to scroll all the way down (I do this by tweening the ScrollBar's value until it reaches 0). However, my problem is that I can't figure out how to do this smoothly over time.
Here's my code snippet:
public void Update() {
if (scrollbar.size < 1 || scrollbar.value > 0) {
LeanTween.value(scrollbar.value, 0, duration).setOnUpdate((float val) => {
if (scrollbar.value == 0) {
LeanTween.cancel(this.gameObject);
} else {
scrollbar.value = val / scrollAdjustment;
}
});
}
}
I tried using "Time.deltaTime" and "Time.time" in place of duration and it did not seem to matter. Here's a gif of what happens:
(In this example, I used "duration" that had the value of 5 (the idea was to have the transition take 5 seconds) and "scrollAdjustment" was 50 but it did not seem to matter what I set either of these values to.
You can see it instantly snaps to the bottom. I'd like this to be a smooth transition. Any help is appreciated!
My settings:
Then here is me scrolling with my mouse wheel while the autoscroll feature is turned off (because I'm using Rewired, I am intercepting an input called "ZoomIn" and "ZoomOut" and add "0.01f * scrollSpeed" (where scrollSpeed is 15 in this case):
You shouldn't need to add any additional code to make the scroll bar function as the way you want it to. Try deactivating your script and mess with your scroll bar. Make sure you have your Number Of Steps On Your Scrollbar Component as 0 to make it smooth. If it's still not working, send some screenshots of your scroll gameobject to see if the rect is the problem or something else.
Imagine some standard Unity UI ScrollView. You grab it with your mouse and start dragging it so it is scrolling with your mouse. How do I programmatically make it stop scrolling while mouse button is still down? Is there any way to make ScrollRect think that user is released mouse button?
Quite old question, but I found exactly this same problem and no clean solution. My problem was to have scrollRect with items which I can scroll left/right but when user select one item and drag it up then scrollRect should cancel scrolling and allow user to drag item up. I achieved this by temporary setting ScrollRect.enable to false, and after few ms set it back to true.
Here is part of mu code which do this. Maybe somebody find this useful.
void Update()
{
if (state == DragState.Started) {
dragStart = Input.mousePosition;
state = DragState.Continued;
}
if (state == DragState.Continued) {
Vector3 pos = Input.mousePosition;
if (pos.y - dragStart.y > 80) {
scrollRect.enabled = false;
state = DragState.None;
Invoke("ReenableScroll", 0.01f);
}
}
}
private void ReenableScroll() {
scrollRect.enabled = true;
}
Its not easy to make the EventSystem think something has happend while it hasn't. I believe its much easier to implement your own ScrollRect logic and parse the mouse input yourself
You can call ScrollRect's OnEndDrag() method with artificial PointerEventData.
var forceEndDragData = new PointerEventData(EventSystem.current)
{
button = PointerEventData.InputButton.Left
};
_scrollRect.OnEndDrag(forceEndDragData);
Here is my code:
using UnityEngine;
public class InputController : MonoBehaviour {
void Update() {
if (Input.GetMouseButtonUp(0)) {
var hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
if (hit.collider != null) {
var e = hit.collider.gameObject;
Debug.Log(e.transform.position.x + ":" + e.transform.position.y);
}
}
}
}
When I click/touch a cell, sometimes the hit is good and the cell is revealed, sometimes the hit is always false (it's like I touch the wrong cell) and sometimes it depends of the position of my click (see images below).
I click the left part of the cell, the console says I click the cell on the left.
I click the right part of the cell, the console says I click the right cell (and reveals it). In this case it's left / right but it can be top / bottom, a corner...
I don't know if my problem is very well explained sorry, and my English is not perfect... Don't hesitate to ask me more details!
Ok I find the problem.
The left cell had a scale of 2 so it overlaps the right cell.
I Guess Here is problem with collider overlaping. you have to just reset all the collider and check it, is it overlaping on any object or not?
you can check colider on gamemode , turn on "Gizmo". so you will see all the collider and check it again is it overlaping on there or not ?
How do I place a UI Button (the new UI) so that it is always at the bottom-left on the screen/viewport? My idea was to do it in code like this:
void Awake () {
fireButton.transform.position = new Vector3(Screen.width - 50, Screen.height - 50, 0);
}
It is not working at all. How can I best do this?
Instead of doing it in code, click on the UIButton in the scene or hierarchy then go into the inspector and in the top left of the transform component you will see a square, click it, hold shift and alt and then click the 'Bottom Left' square to latch it to that side of the screen.
My game uses a registration form scene in order to register a user. I've got several Textboxes(UIInput) on screen.
I would like to have Next/Previous Button over the keyboard which appears when i select a text box for input. this way i will be able to navigate on multiple textboxes in the registration form.
right now i am using HideInput=true so there is nothing over the keyboard
I am sure you have Box Collider "using UIInput",
Simple way would be to add UIButton To your InputBox.
Once you do that attach scene GameObject or PrefabObject, with a public method() to the UIButton OnClick Notify option, Select Method from the drop down.
Test Code:
Private Bool ShwNxtBtn = false;
Public Void MethodName(){
if (ShwNxtBtn != true){
ShwNxtBtn = true;
}else{
ShwNxtBtn = false;
}
Note: you could use Toggle, but I've had some issue with that and input Collider.
