Defold 1.2.164 has been released


Defold 1.2.164

In this sprint we’ve added support for multi touch on HTML5.

We’ve also fixed some iOS 13 related issues, related to our iOS app code.
(E.g. modal popups now work properly.)
This however means we had to do some big changes, so if you are an extension developer, be sure to read the more detailed information below.
The two major breaking changes are regarding callbacks outside of the main thread, and the registration flow for app delegates.

There have also been a number of other great additions and fixes.

Native Extensions

iOS Application Loop + OS Callbacks

This is a breaking change.

Previously, we had a custom startup procedure, allowing us to keep ownership of the event loop on the main thread.
Now however, we use a regular application loop, but that also means that callbacks from the OS is likely to not come from the main thread.
(This is how it was already working in our Android version.)
As a developer of UI applications, this is a common problem, you get a callback from a non UI thread, and need to pass info to the UI thread.
The solution in our case is to store the needed data for a period of time, and then process that data on the UI (main) thread.

As an example, you can look at extension-push,
where we protect an array with a mutex. We push to the array from the non-UI thread, and we read from the array on the UI thread.

dmExtension::RegisteriOSUIApplicationDelegate + dmExtension::UnregisteriOSUIApplicationDelegate

This is a breaking change.

Due to the new application loop, we needed a new way to register the app delegates.
This is now done via a static initializer in order to be able to hook into the engine before the UIApplicationMain()is called.

See example here

Lua Callbacks

To help in the process of refactoring our extensions, we added a few extra functions to manage Lua callbacks.

  • struct LuaCallbackInfo;
  • LuaCallbackInfo* dmScript::CreateCallback(L, index)
  • void dmScript::DestroyCallback(LuaCallbackInfo* cbk)
  • void dmScript::SetupCallback(LuaCallbackInfo* cbk)
  • void dmScript::TeardownCallback(LuaCallbackInfo* cbk);
  • lua_State* dmScript::GetCallbackLuaContext(LuaCallbackInfo* cbk)
  • int PCall(lua_State* L, int nargs, int nresult);

We also added a helper function void dmArray::Map(void (*fn)(T* value, void* ctx), void* ctx); that makes it easy to map a function over all elements in an array. We use it to handle all queued up callbacks from the non-UI threads.

You can see a practical example here


In the event of a crash in the native code, our crash handler will be invoked.
We’ve now also added a printout, for easier sharing of info in such an event.

Debug symbols

We’ve made some improvements on how to deal with the debug symbols.
It’s important to keep debug symbols for each release of your game, for debugging any native issues that might pop up.
This is especially true if you are using native extensions, since we build a custom engine in the cloud for you.
(If you are not using native extensions, we keep the debug symbols on the download page)

When you opt to bundle with debug symbols, we will bundle these symbols next to your bundle.
The layout for each platform is different, here is the layout:

Is it lua_pcall()? I strongly advise not to use lua_pcall() when invoking callbacks, because when there is an error inside the callback, the developer is not notified about it. The app doesn’t work and it’s unclear why.

It is, and we don’t usually have troubles with it?
From the documentation (which isn’t up yet):

“This function wraps lua_pcall with the addition of specifying an error handler which produces a backtrace.
In the case of an error, the error is logged and popped from the stack.”



Ok, it’s just before you were using lua_pcall() in the push extension without the error function and I didn’t like it.



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 :confused:




Perhaps, I’ve found two issues on iOS with 1.2.164

  1. 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)


Also @sergey.lerg has something similar bug on his apps.

  1. Crash extension callback when there is an error in Lua callback.
    my case:

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 :confused:

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 :confused:



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. :slight_smile:

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?


High DPI Window Size Discrepancy

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()



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:

Could you try to make iOS bundle of this one and test it?
