This field represents if the class is exposed to the scripting API.
The value is 'true' if the class was registered manually ('ClassDB::register_*class()'), otherwise it's false (registered on '_post_initialize').
- Added missing registration of classes that are meant to be exposed.
Previously logging logic was scattered over OS class implementations
with plenty of duplication. Major changes in this commit:
- Extracted logging logic into a separate Logger hierarchy. It allows
easy configuration of logging mechanism depending on compile-time or
run-time configuration.
- Implemented RotatedFileLogger which is usually used with StdLogger,
providing persistency of logs. It is often important to be able to
obtain logs of the game even in production to be able to understand
what happened prior to some problem. On mobile there previously was
no way to obtain the logs aside from having the device connected to
your machine.
- flush() is not performed in release mode for every logged line. It
is only performed for errors.
Rename user facing methods and variables as well as the corresponding
C++ methods according to the folloming changes:
* pos -> position
* rot -> rotation
* loc -> location
C++ variables are left as is.
The changes include work done to ensure that GDNative apps and Nim
integration specifically can run on Android. The changes have been
tested on our WIP game, which uses godot-nim and depends on several
third-party .so libs, and Platformer demo to ensure nothing got broken.
- .so libraries are exported to lib/ folder in .apk, instead of assets/,
because that's where Android expects them to be and it resolves the
library name into "lib/<ABI>/<name>", where <ABI> is the ABI matching
the current device. So we establish the convention that Android .so
files in the project must be located in the folder corresponding to
the ABI they were compiled for.
- Godot callbacks (event handlers) are now called from the same thread
from which Main::iteration is called. It is also what Godot now
considers to be the main thread, because Main::setup is also called
from there. This makes threading on Android more consistent with
other platforms, making the code that depends on Thread::get_main_id
more portable (GDNative has such code).
- Sizes of GDNative API types have been fixed to work on 32-bit
platforms.
- The Windows, UWP, Android (on Windows) and Linux builds are
tested with Scons 3.0 alpha using Python 3.
- OSX and iOS should hopefully work but are not tested since
I don't have a Mac.
- Builds using SCons 2.5 and Python 2 should not be impacted.
Currently we rely on some undefined behavior when Object->cast_to() gets
called with a Null pointer. This used to work fine with GCC < 6 but
newer versions of GCC remove all codepaths in which the this pointer is
Null. However, the non-static cast_to() was supposed to be null safe.
This patch makes cast_to() Null safe and removes the now redundant Null
checks where they existed.
