[bug] Switching orientation breaks the AR

[marcusx2]

If I switch the orientation on the phone from portrait to landscape and vice versa, the augmented content disappears permanently.

Apparently this bug was already reported here. Will it be fixed? This is a pretty big deal...I can't use mindarjs in production like this.

[marcusx2]

@hiukim Any thoughts on this? Will it be fixed, or are there currently no plans to fix it?

[hiukim]

Yes, currently it will break if device changes orientation. I agree it needs to be handled. I will look into it when I have some free time.

[marcusx2]

Ah ok. For now I'll need to use zappar. ARJS' image tracking is just not good enough, and switching orientation is really important for production. I can't just tell the client not to switch orientations T_T. I hope this gets fixed soon.

@hiukim Will this be fixed soon? ;_;

[hiukim]

@marcusx2 sorry, unlikely. At least not these two weeks. Busy with work lately.

[marcusx2]

Is there any workaround while this isn't fixed?

[arslc]

@marcusx2 try this:

window.addEventListener('orientationchange', () => {
 //stop mindar
 mindar.stop()

 //ur function to hide 3D object (optional)

 //restart mindar after 1 second delay
 setTimeout(()=>{
  mindar.start()
 }, 1000)

}, false)

Not the most elegant way, but as a temporary solution it may help.

P.S. I know, this is deprecated event, but it still work on iOS 16. So we can use that until @hiukim not fix this bug

[marcusx2]

@arslc Thanks this is a good enough workaround, it works just fine!

[arslc]

@marcusx2 Glad it helped :) @hiukim Probably should be closed issue?

[marcusx2]

@arslc I don't think it should be closed. I think we should be able to rotate the phone without having to stop and start the AR engine again. This is still just a workaround in my opinion.

fixed in v1.2.2
