Well, we haven’t had access to all internal sdk functions in our extensions, but we’re getting there little by little. This one we’ve used for many years internally, we just had to temporarily switch to lua_pcall in the external code.

There were somewhere a practical example of that, I remember I played @Dragosha’s Slasher based example on mobile browser, but now I can’t find it

Perhaps, I’ve found two issues on iOS with 1.2.164
- Crash an app after wakeup iOS.
- run app
- wait for device sleeping
- wakeup device
- an app immediate collapses
I’ve tested the game with and without Native extensions, the same results.
Tested on iPadOS 13.1.3, iPAD Pro 12.9 (first generation)
Console:
Also @sergey.lerg has something similar bug on his apps.
-
Crash extension callback when there is an error in Lua callback.
my case:
- In some case my app had an error in msg.post (deprecated url) inside a Lua callback called from IAP extension (listener)
- crash after PCALL https://github.com/defold/extension-iap/blob/master/extension-iap/src/iap_ios.mm#L321
This bug is found Apple review team in my last build when try “restore purchases” (they tested on iPad running iOS 13.2.2), after that I had a little research and reproduced that on iPAD mini 2, iOS,12.3.1.
I fixed my Lua code and have no that issue anymore, BUT, old code worked with my Lua error a year…
sorry, no screen from console made.

Hmm, I couldn’t reproduce it yet
About the crash log, can you perhaps download it with the Download container?
You’ll find this in the window XCode -> Devices and Simulators
I have a crash log from a tester
LunarOrbit-2019-11-28-120919.txt (87.4 KB)
Happened after resuming the game after the ipad was locked.

Is this a vanilla build? I.e. no extensions?

Since I assume it’s a custom build, and I don’t have the unstripped exe, I cannot symbolicate
Many extensions. Can’t reliably reproduce it myself, so hard to make a case.
Understandable. I’d like to remind anyone of keeping the exe+debug symbols for each release you do, for this exact purpose.

This is for HTML5 builds (tested with Scale mode: Downscale Fit, but probably the same for other scaling modes)
On 1.2.163:
window.WINDOW_EVENT_RESIZED is being called immediately upon game launch (callback is registered from init)
On 1.2.164:
window.WINDOW_EVENT_RESIZED is only called if you start resizing the browser manually. However, the original game project’s dimensions may already be different upon game launch, so there is currently no way to detect the new dimensions immediately?

We have in our backlog for 1.2.165 to add more functions to window.* to read the window size at any time, something like window.get_size()

Hi,
I’ve tried to reproduce the issue with other my apps without native extensions and got the same error in console.
Steps to reproduce:
- run app
- wait for device sleeping
- wakeup device
- an app immediate collapses (collapses if debug bundle or just freeze if release bundle)
An open source example for testing: https://github.com/Dragosha/slasher-prototype
Could you try to make iOS bundle of this one and test it?
I tested on iPad6,7 (iPad Pro 12.9" first generation) OS Version: iPhone OS 13.2.3 (17B111)

Hi @Dragosha, I’m trying to reproduce this issue, but I cannot seem to do so.
Do you still see this crash?
Hi @Mathias_Westerdahl , on old builds (May 2020), yes, still. I will test with 171 and back to comments.

Well, I’ve rebuild ‘slasher-prototype’ with 171 and run it on iPad with newest iOS 13.6
and catch the same issue, but now with important ‘error-script’ remarks:
Seems, render.get_window_width() and render.get_window_height() return wrong value after iPad was wakeup. Now I’ll try to check this values in update(), as @britzl suggests in the linked topic.

So, added values checking to rendercam render-script:
but it not helps, just prevents from error-script messages in console
@totebo are you complete solved this issue here? Crash when app comes back from sleep

The error still happens, but doesn’t seem to cause a hard crash. I think the Orthographic camera helper module needs to be patched to fix the remaining errors.

Seems issue is fixed
Not sure what helped: transfer OS on my iPad to iOS 14 (from 13), 1.2.177 version of Defold or additional get_window_with checking in render script, but LyL is correct waking up now.
Happy holidays!

Happy to hear that! @JCash has made changes to the application lifecycle and state handling, although mostly on Android.
