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.
Apparently -ffast-math generates incorrect code with recent versions of
GCC and Clang. The manual page for GCC warns about this possibility.
In my tests it doesn't actually appear to be measurably slower in this
case, and this is used in a batch process so it seems safe to disable
this.
This fixes#10758 and fixes#10070
- Makes vararg methods automatically use PROPERTY_USAGE_NIL_IS_VARIANT on return types
- Completely removes the ":type" suffix for method names. Virtual methods must use the MethodInfo constructors that takes Variant::Type or PropertyHint as the first parameter for the return type (with CLASS_INFO as a helper to get the PropertyInfo). Parameters must use PROPERTY_HINT_RESOURCE_TYPE and hint string.
- PROPERTY_USAGE_NIL_IS_VARIANT is no longer needed for parameters, because parameters cannot be void.
- Adds missing PROPERTY_USAGE_NIL_IS_VARIANT to virtual and built-in methods that return Variant.
- 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.
-Make sure handles are always visible (on top)
-Fixed instanced scene selection (should work properly now)
-Added interpolated camera
-Customizable gizmo colors in editor settings
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.
