Unity Remote Multitouch

Hi,

do I have to enable something to work with the multitouch input when I use Unity Remote? Thank you.

 

No your code just has to make use of multiple touches

 

Thank you for the answer.

I asked that because what I have is a normal behavior when I build an iOS app, but on Unity Remote instead, the code behaves like if it recognizes only one finger.

 

perhaps you have code that disables multitouch, you disabled it in the remote or you built it through OnGUI which by definition is not multitouch capable at all

 

Thank you again. How can I disable it in the remote? (sounds like the only plausible one)

 

if you use the one from appstore you can't, so no worries there.
in that case you would have disabled it in code or you just don't make use of Input.touches / Input.GetTouch in the right way

 

ok, last question, on AppStore I can find 2 version of Unity Remote, which one should I use?

 

Unity Remote 3

the other one is for unity iphone 1.x which hopefully nobody is using any longer

 

Right, thank you very much then, it seems everything all right, I must have made a mistake somewhere.

 

Me again.

I double checked the code, there is nothing special and I can confirm again that while the multi-touch works normally if I build the app and run it on the iPad 2, it does not work if I use the Unity Remote connecting it to a macmini running Snow Leopard Server.

I do not know what is going on, but I do not see much space for a mistake in code, which behaves normally, since Input.multiTouchEnabled returns false!

How can Unity Remote support the multiTouch if it is not even enabled?

Using the remote would be really useful since tweaking the input settings is very time consuming when I have to deploy to the iPad.

Thank you for your precious help.

 

input.multitouchenabled likely returns the state of the device it runs on -> your mac

keep in mind, NO code is execute on the remote, so also stuff like #if UNITY_IPHONE is failing in such a case for example.

but its strange that it should not work with multitouch anymore as it worked from unity iphone 1.x until the last time I tested it on 3.3 or 3.4 on my itouch 3, itouch 4 and ipad1

 

yep, that is what I thought. So I removed all the UNITY_IPHONE defines, but still, multitouchenabled returns false, how is it supposed to work?

Anyway, I made several tests and this is the result so far:

multiTouchEnabled always returns false (which already does not make any sense and makes the Unity Remote useless)
Input.TouchCount returns the correct value
Touch.phase allegedly seems to return always stationary
Touch.position seems to return alway 0

 

Hi Sebas77,

Did you found how to make Unity Remote 3 work with multitouches? I am experiencing the same issue here

 

multiTouchEnabled does not work with remote, it's a known limitation.
Touch.phase, Touch.position should work just fine, maybe it's a shaky WiFi connection?

 

I debuged the code I am using and Input.touches[] at most only has one element
while running the same application on the device works flawlesly

 

Thanks Unity's staff and again, Dreamora, stop responding if you don't know "again" what you're talking about... It's a old post but you're still doing this ! You are very boring, and you keep wasting all people time... So please stop your annoying spam. Thanks

 

I ran into this issue as well, and it turns out that it was an issue in TouchInputModule.UseFakeInput(). This function checks Input.touchSupported, which as of 5.0.1f3 always returns false in the editor. I make a copy of the file at https://bitbucket.org/Unity-Technologies/ui/src/cc791b3335d2d46b70d932fc70e6ec6c4ea6d561/UnityEngine.UI/EventSystem/InputModules/TouchInputModule.cs and modified UseFakeInput() to always return false. This seems to have fixed my issue for now. A better long-term solution would be for Input.touchSupported to return true when Unity Remote is connected.

 

LOL at this thread being necro'd to yell at @Dreamora for something he said 4 years ago.

 

@_clewis_ Can you please elaborate on your actions for fixing the multitouch issue? Did you just insert the file into your project? I am using a joystick plugin and I get the "The imported type `UnityEngine.EventSystems.TouchInputModule' is defined multiple times" error.
