Mobile/Touch interfaces often feature a long press gesture, that triggers after touching a specific point on the screen for a period of time (ie 500ms). This would be a neat addition to the input manager.

I've found this project incredibly helpful for building the mobile/touch camera input for my 3D project. I wanted to use the SingleTouch/SingleTap events for selecting objects in the scene howevever the events don't appear to propogate through to the CollisionObject input_event signal.

https://docs.godotengine.org/en/stable/classes/class_collisionobject.html

I've had a look through the Readme here and also at the Godot documentation, there doesn't appear to be a simple way to enable this.

Here's two ideas on how this could be achieved:

1. emit a raycast from the primary camera whenever these events are triggered and then call _input_event on the collider.
2. provide a helper function for converting the Godot touch events inside of a _input_event handler (leveraging the existing raycasts), for example:

func _on_input(camera, event, position, normal, shape_idx):
    var gestures = InputGestureEvents(event)
    for gesture in gestures:
        // handle events

I have this warning on v4.2.1.stable.official, no sure if this is something of concern ?

InputManager.gd:288 @ _emit(): An input event object is being parsed more than once in the same frame, which is unsafe.
If you are generating events in a script, you have to instantiate a new event instead of sending the same one more than once, unless the original one was sent on an earlier frame.
You can call duplicate() on the event to get a new instance with identical values.

Hello developers,

This image above is a map with buttons on them.
There seems to be an issue when pinching over these buttons.

There is an option for "mouse filter". This is useful when using a ScrollContainer containing buttons . ScrollContainer also has a "deadzone" to avoid touching and dragging issues over buttons.
Looking into these can help solve the problem.

Great work on the Plugin!

This addon looked incredible promising, and I would have loved to use it in my Android projects, but upon first testing it seemed very laggy and buggy.

To test my impression, I added a simple counter to check if all my taps are registered:

extends Node2D

onready var label = $Label
onready var label2 = $Label2


var tap_counter = 0

func _input(event):
	if (event is InputEventMultiScreenDrag or
		event is InputEventSingleScreenDrag or
		event is InputEventScreenPinch or
		event is InputEventScreenTwist or
		event is InputEventSingleScreenTap or
		event is InputEventSingleScreenTouch):
			label.text = event.as_text()
	if event is InputEventMultiScreenDrag:
		label2.text = "Multiple finger drag"
	elif event is InputEventSingleScreenDrag:
		label2.text = "Single finger drag"
	elif event is InputEventScreenPinch:
		label2.text = "Pinch"
	elif event is InputEventScreenTwist:
		label2.text = "Twist"
	elif event is InputEventSingleScreenTap:
		tap_counter +=1
		label2.text = "Single finger tap "+ str(tap_counter)
	elif event is InputEventSingleScreenTouch:
		label2.text = "Single finger touch"

My impression seemed correct since taps after a certain frequency don't register at all any more.
That's very unfortunate, because the features of this addon would be really amazing if they would work.

Pinch and "Twist" also did not seem reliable at all, constantly switching to "Multiple finger drag"

Thanks for the great library!

The only thing that was missing for me was position finger X. In one application I'm just drawing lines for which I need start vector, end vector.

Can those be pulled out of RawGesture presses[]?

Area3D touches are not obtained and the documentation is not clear how to solve this, any help?

This is what I tried:
if event is InputEventScreenTouch and event.pressed:

When InputEventSingleScreenLongPress is triggered, then an Invalid get index '0' (on base: 'Dictionary') error occurs.
I use Godot 4.4 and GodotTouchInputManager v2.1.0.
This can be reproduced in https://github.com/Federico-Ciuffardi/GodotTouchInputManager-Demo.

I updated my Gogot engine from 4.1.3 to 4.2.1 and touches stopped to work on mobile. When I downgraded back to 4.1.3 it is working now again.

I'm guessing this is a typo ?

Replacing as_text for as_string shows the debug messages correctly:

if DEBUG: print(val.as_string())

Nice work! Here's a minor bug I ran into.

Environment

• Godot 3.2 stable
• Deployed to iPhone X

How to reproduce

Run the following code and pinch the screen.

	if event is InputEventScreenPinch:
		print(event.position)

Expected behavior

event.position is always centered

Encountered behavior

event.position is not centered but contains the last value of InputEventSingleScreenDrag for the first few events when starting to pinch the screen.

hi thanks for your project.
i downloaded the files and also demo files.
but it's not working.

ciao,
vedo che sei italiano quindi bentrovato!
Vedo che usi oggetti che chiami "InputEvent*", ma in realtà non sono oggetti compatibili con la classe InputEvent dell'engine in quanto di fatto utilizzi segnali e non eventi.
Per quanto è vero che un nome è sempre e solo un nome, nella pratica è altamente fuorviante, perchè viene automatico pensare di scrivere in _input(event) if event is InputEventScreenPinch: che non funzionerà mai.
Consiglio di cambiare nomi a questi oggetti, al fine di mantenere chiarezza e linearità con il resto dell'engine.

ciao

I add player control to the already prepared scene using your plugin. The player doesn't move and I get an error:

E 0:00:02.469 _input: Condition "!is_visible_in_tree()" is true.
<C++ Source> scene/2d/touch_screen_button.cpp:201 @ _input()

If I remove everything from the tree except the player, then there is no error and he moves.
What am I doing wrong?

I need help with managing pan gesture. Currently I'm facing problem with zooming and panning. The panning interferes with zooming controls and I dont know how to fix them.

First, excellent plugin! I'm developing a little Tetris game for mobile and have been using your plugin with great success. Up until now. :)

I have made a pause menu for my game now, and using the in-built Godot pause system by setting get_tree().paused = true. And when I resume the game again with get_tree().paused = false, my single finger taps are no longer recognized. Drags and long presses are. Really weird... On the computer it works, but not on the mobile.

I've been looking through InputManager.gd and testing out a few things, but couldn't get it to work no matter what. I really don't know what's causing this. Could there be some timers that are still running in your script even if the game is paused, and they therefore go out of bounds? I see this condtion:

if raw_gesture.elapsed_time < TAP_TIME_LIMIT and distance <= TAP_DISTANCE_LIMIT:
					_emit("single_tap", InputEventSingleScreenTap.new(raw_gesture))

I figured that maybe raw_gesture.elapsed_time was being incremented during pause, but I really have no clue what's going on in your code.

Do you think you could maybe take a look in this?

Ive been searching for 3 days and still couldnt find it, i can detect a swipe, but i dont know how i can get the direction, looking at the code it seems to be EMITTED, but the emission dont work when i connect them via code or via godot ui, and they dont come with VARAGRS.

any kind of help is appreciated.

hey there - I went to load this asset in Godot 3.2 and got the following error:

Asset Download Error
Bad download hash, assuming file has been tampered with.

Hey, have you worked out a way to detect when a swipe has ended? Is there a way to use is_action_just_released with InputEventSingleScreenDrag?

I've been trying to hack something together for a few days no with no luck, so I thought I'd see if it's something you'd already solved.

Thanks for your code base.

I'm playing around with the current alpha of Godot 4 (4.0-alpha14), and there's quite a few changes which need to be made for at least importing properly.

I can provide a patch but it would probably need a new major version or branch because the changes are not backwards compatible.

Again, great work! I've got a minor suggestion when it comes to consistency of event attributes:

Under drag events like InputEventSingleScreenDrag, event.relative relates to event.position. Under InputEventScreenPinch and InputEventScreenTwist, however, event.relative relates to event.distance and angle (the former undocumented btw) while event.position is still present.

I think it'd be preferable to keep event.relative related to event.position and introduce different attributes for distance and angle.

Is there currently a way to have multi tap events fire regardless of finger distance? I tried editing some InputManager constants to no avail.

PS: thanks a ton for making this! if you're at all interested I can create a pull request for C# compatibility

It works in _input(). But is there a way to have it work in _gui_input?

THIS ONLY OCCURS ON GODOT WEB EXPORT:
The fingers property of input event InputEventMultiScreenDrag is not reset.
It always contains the maximum number of fingers that triggered that event.
So if you triggered the event with 2 fingers, then fingers = 2.
After that, you trigger the event with 3 fingers, then finger = 3.
Then you trigger the event again with 2 fingers, then finger = 3.

I'm working on a tapping game, and due to the fast pace it happens where the player can tap with multiple fingers, on different objects, currently using single_tap which wont register any of those taps which can be frustrating.

I found a way to get to get the position of multiple taps from InputEventMultiScreenTap by looking into the raw_event.centroid function, and i can make a push request to add something like InputEventMultiScreenTap.positions array with them if you'd want.
But more than that I think it could be helpful to have a signal that is emitted on either single_tap or multi_tap, with positions array property for cases such as mine.
I can also implement this.

thanks for the great plugin!

So following the demo, this works

But this does not

I am unfamiliar with the differences between the two in Godot, so this may just be a misunderstanding. Using emulated touch from mouse if I put my cursor at the border of the window and scroll I am able to get a pinch event, but anywhere else it comes in as a normal InputEventMouseButton.

I am using this to test:

func _unhandled_input(event):
	if event is InputEventScreenPinch:
		print("Pinch: " + str(ev.speed))

I have also tested with a different project using pinch to zoom in and out, with a web export and using an Android browser. The behavior seems to be the same.

Swipe and tap input not received when use get_tree().paused on Mobile device.
Godot version: 4.1 rc, 4.0 stable.
Device testing: Android 11, iPhone 11.

Steps to reproduce:

• Use get_tree().paused = true then get_tree().paused = false for UI show, hide (pause mode).
• Swipe and tap input not received anymore. (Ex: InputEventSingleScreenSwipe and InputEventSingleScreenTap)
• Other inputs such as drag, touch, pinch are still received normally.
