Input.acceleration

Is this item different on windows store apps then on iOS and Android?

When we ported from Android to iOS we never changed the Input.acceleration code at all. however on windows store (WinRT tablet) we seem to be getting wildly different values.

 

Hello,

Changing it to true didn't help so i peeked at it with the debugger and it is already true.

EDIT: made a dummy project. it appears as your team's "if" statement is reversed. if i set it false it seems like i am getting values like i expected on iOS and Android.

 

Win RT tablet (first model) portrait mode with the windows button on the bottom of the screen. I.E. "kickstand mode"

i don't know how to explain this but i will try pseudo code

bool flipAxis = false;
if(deviceMode == KickstandMode)
{
flipAxis = true;
}


if(flipAxis)
{
float tmp = Input.acceleration.x;
Input.acceleration = Input.acceleration.y;
Input.acceleration = -tmp;
}

EDIT: tried to submit the project to the bug reporter but it errored out. how can i send a project to bugs@unity.com?

EDIT2: uploaded project to google drive. put in email bug report. #596479

 

Don't really want to harp on this however, i just ported our game to winphone 8 and it seems so far the acceleration values are similiar to ios and android. it does appear to be a winstore app bug.

 

please review above. i have already submitted a bug report with example project.

my mistake above. thought landscape... typed portrait. i do apologize. i am always holding my RT tablet in landscape mode. when in landscape mode. the kickstand and windows button are on the bottom of the device.

the fact remains though that if i compare the Input.acceration values of a WinRT project to those of WinPhone, iOS, and Android they are not the same. the latter 3 are the same.

to me it seems that
iOS.Input.acceration.x = winStore.Input.acceration.y;
iOS.Input.acceration.y = -winStore.Input.acceration.x;
iOS.Input.acceration.z = winStore.Input.acceration.z;

I think you can plainly see the values are not the same.

Again link to project that generates these screenshots is in bug report. #596479

 

please check again readings do not match.

If you have a test project. please post it i'll download it and load it on my devices to prove to either me or you it works or doesn't

EDIT: side note. just a documentation update but the docs for this function do not state anywhere that it is dependent on the project being in portrait or in landscape. the only "hint" we have is a comment in the example that states that the home button is on the right hand side. I'm assuming this is iOS since android doesn't have a home button. however that would mean to me that ALL devices regardless of the project being in landscape or potrait. if the device is held in landscape mode with the equivalent home button on the right then they all will receive the same value. that clearly is not the case here. so it seems at least the documentation needs an update to state that accerlation values are dependent on the project's landscape/portrait orientation and the location of the home button when in that orientation.
