[iOS] Accelerometer and Gyroscope bug.

cmontiel · 03-28-2012 01:34 AM

1) Build tutorial.
2) Minimize
3) Maximize
4) Gyroscope and Accerometer not working.

Tested on iPad 3.

Thanks, I'll test it

I've tested this with latest EE iOS SDK released few days ago on iPad 1, start, minimize, resume, and accelerometer continued to work (gyroscope is not present on ipad1)

Good to know that it works on iPad 1.

But I tried the tutorial a lot of times on iPad 3, and it doesn't work. After resume, the values don't change and show the same values when was minimized.

I'll check this on different versions of Simulator

I've found some code which may have caused the issue. I hope this should work OK in next release.

Fixed!

Today I double checked this.

For some reason the first time I tested on iPad 3 they were working. After donwload again the ios sdk and remove the old tutorial projects, Accelerometer is working as expected but Gyroscope values are 0,0,0 always. You don't need minimize.

Also compiling for simulator, it drops new undefined symbols:

Up. Tested with build 4.

Compiling for simulator => undefined symbols.
Gyroscope not working. Values 0,0,0. (Device iPad 3, iOS 5.1)

**Esenthel** · 05-26-2012 06:55 PM

Hello,

I did test the simulator, iPhone/iPad 4.3/5.0, XCode 4.2, and it worked fine.
Please download iOS SDK to new folder, and run it from there without any manual changes/editions

I did also test the gyroscope in iPhone 4 using iOS 5.0.1 and it works fine.

After updating phone to iOS 5.1.1 it all works fine as well.

cmontiel · 05-27-2012 05:11 PM

I'm using XCode 4.3.2.

On the iPad, I have iOS 5.1.1

I have just downloaded the iOS SDK build 6 (new folder, clean installation, iOS 5.1 is set by default without manual editions).

Simulator => OK.
Device => Undefined symbols, this time DrawParticleAdd and DrawAnimatedParticleAdd.

Code:

Please someone can confirm this with the latest esenthel ios sdk?

**Esenthel** · 05-27-2012 07:16 PM

Thanks, I've upgraded my xcode and now see the same problem, I will fix this shortly.

**Esenthel** · 05-27-2012 07:54 PM

I've reuploaded the iOS SDK.

cmontiel · 05-27-2012 08:22 PM

Simulator => OK!
Device => OK!

Gyroscope => values 0,0,0. This feature is not important to me, I don't need gyroscope for my game but I pretty sure that something is wrong.
