Multitouch not working in 3.4.3 Release in iOS

[SkanerSoft]

Godot version

Godot 3.4.3 Release

System information

iOS 15.2.1 / iPhone SE / OpenGL ES 2.0 Renderer: Apple A9 GPU

Issue description

First there were big glitches with touches in 3.4.3 RC 2 and I couldn't test multi-touches in it because of this issue - #58274

In the new version, this problem was fixed, but multitouch does not work completely.

Steps to reproduce

The problem concerns both the _input and the SreenTouchButton events.

I have no way to run deeper tests to find out the cause of the problem, but this again prevents me from releasing the game for iOS...

Minimal reproduction project

Any project with touch input control.

On my own project I wasn't able to reproduce an issue. I guess an MRP is required for this one.

@SkanerSoft please try this branch naithar@f6fbe06 you should be able to use GitHub built template from here: https://github.com/naithar/godot/actions/runs/1904075045 once it's finished.

Unfortunately, I don't have that option. The build of the game is being done by a friend of mine who is currently unavailable for the next few days.

I'm getting this result with the fix.

The fix probably works, but I can't test it yet. I don't have a macbook to compile the game and my friend can't do it right now. I believe it works and am waiting for the 3.5 beta 2 update to test it out. Hope it comes out as soon as possible! Thanks for your work!

@SkanerSoft The fix is included in 3.4.4 RC 1 released today: https://godotengine.org/article/release-candidate-godot-3-4-4-rc-1
It would be great if you could confirm that it works fine for your project before we release 3.4.4 stable.

Hey guys, I've been trying to implement multitouch in my game today and came across this thread. I'm building primarily for IOS and I can confirm after installing 3.4.4 RC1 and then building out the game, that multitouch still isn't working for me. Has anyone else tested it on hardware?

I tested on an iPhone 8, which is my primary testing device.

Essentially I'm adding the touches to a dictionary, and displaying them on screen. I never get more than 1 index. My code is more complex, but I've been testing it like so

var _touches = {}

func _unhandled_input(event) :
	if event is InputEventScreenTouch:
		_touches[event.index] = event

[naithar]

Just tested 3.4.4.rc1 from https://downloads.tuxfamily.org/godotengine/3.4.4/rc1/ with this code:

func _unhandled_input(event):
	if event is InputEventScreenTouch:
		print("Index: " + str(event.index) + ", pressed: " + str(event.pressed))

Had to rename templates folder from 3.4.4-rc1 to 3.4.4.rc1 to force Export to work.

Got this logs from XCode project:

Fix seems to be working.

[CarlosRios]

You're right! error was that I hadn't downloaded the new export templates. Changing the folder did it for me as well.

Had to rename templates folder from 3.4.4-rc1 to 3.4.4.rc1 to force Export to work.

Oops, I'll have to fix my scripts to prevent this from happening.

It would be great if you could confirm that it works fine for your project before we release 3.4.4 stable

@akien-mga

Hey! Yes, it works well. It's true that the octahedral compression issue hasn't gone away on iOS, but that will be in another post. Not here.

[akien-mga]

@SkanerSoft There has been more fixes for octahedral compression after 3.4.4-rc1, I will release 3.4.4-rc2 today or tomorrow to validate them. See #58592 for details.
