If at the time of the _GLOBAL_DEF call a setting itself was unknown,
the function would always return the supplied default value instead of
checking for overrides. This commit changes that, lookup now always
happens which correctly takes overrides into account.
I had a situation coming from godot-python where the caller of
Variant::get_call_error_text() passed null for `p_argptrs`. In
addition to fixing that in the caller, seems like good practice to
defend against that situation in the callee to prevent a crash.
So this patch just substitutes some semi-useful text for the source
type name and keeps going so the user's actual error gets emitted.
Now generating mouse events from touch is optional (on by default) and it's performed by `InputDefault` instead of having each OS abstraction doing it. (*)
The translation algorithm waits for a touch index to be pressed and tracks it translating its events to mouse events until it is raised, while ignoring other pointers.
Furthermore, to avoid an stuck "touch mouse", since not all platforms may report touches raised when the window is unfocused, it checks if touches are still down by the time it's focused again and if so it resets the state of the emulated mouse.
*: In the case of Windows, since it already provides touch-to-mouse translation by itself, "echo" mouse events are filtered out to have it working like the rest.
On X11 a little hack has been needed to avoid a case of a spurious mouse motion event that is generated during touch interaction.
Plus: Improve/fix tracking of current mouse position.
** Summary of changes to settings: **
- `display/window/handheld/emulate_touchscreen` becomes `input/pointing_devices/emulate_touch_from_mouse`
- New setting: `input/pointing_devices/emulate_mouse_from_touch`
Fixes reported logically dead codes by Coverity
* image.cpp: Doesn't really need any modification. But to remove the bug
report then we have to move the MAX call away from the for loop
statement.
* rasterizer_gles3.cpp: Removes unnecessary elif condition since it is
checked earlier in the function
* collada.cpp: If stamement never reached due to macro ERR_CONTINUE does
the same.
* navigation_mesh.cpp: Variables should always be null - however, also
checked for the very same condition in their function call. Leaving this
for review (whether the function call is necessary or not)
* path_editor_plugin.cpp: If cancel is true, then it should restore the
edited value to the original provided.
http://docs.godotengine.org/en/3.0/classes/class_editorspatialgizmo.html#class-editorspatialgizmo-commit-handle
* spatial_editor_gizmos.cpp: the very condition of i >= 3 is
predetermined in the if case right before it. Thus case 1 is always '1'
and case 2 is always '-1'
* grid_map_editor.cpp: Same as above in spatial_editor_gizmos.cpp
* voxel_light_baker.cpp: Same as above in spatial_editor_gizmos.cpp
* visual_server.cpp: Same as above in spatial_editor_gizmos.cpp
* visual_script_expression.cpp: char '-' is already true in the switch
case mechanism. Thus it can never reach to default case.
* particles.cpp: Case 'PARAM_MAX' is unreachable due to index checking
right before the switch execution.
* shader_language.cpp: Invalid index is handled in switch default case.
`type < TYPE_FLOAT && type > TYPE_VEC4` -> `(type < TYPE_FLOAT || type > TYPE_VEC4`)
Fixes the "always false problem" in TODO comment.
Fixes most current reports on Coverity Scan of uninitialized scalar
variable (CWE-457): https://cwe.mitre.org/data/definitions/457.html
These happen most of the time (in our code) when instanciating structs
without a constructor (or with an incomplete one), and later returning
the instance. This is sometimes intended though, as some parameters are
only used in some situations and should not be double-initialized for
performance reasons (e.g. `constant` in ShaderLanguage::Token).
- StringName::StringName(const StringName &p_name)
Non-static class member _data is not initialized in this constructor nor in any functions that it calls.
- StringName::_Data()
Non-static class member idx is not initialized in this constructor nor in any functions that it calls.
- String::num_uint64(...)
This less-than-zero comparison of an unsigned value is never true. n % base < 0UL.
- String::hex_to_int(...) and String::hex_to_int64(...)
Execution cannot reach this statement (deadcode)
Also ensure that get_scale doesn't arbitrarlity change the signs of scales, ensuring that the combination of get_rotation and get_scale gives the correct basis.
Added various missing functions and constructors.
Should close#17968.
Starting from April 2018 Apple no longer accepts apps that do not
support iPhone X. For games this mainly means respecting the safe area,
unobstructed by notch and virtual home button. UI controls must be
placed within the safe area so that users can interact with them.
This commit:
- Adds OS::get_window_safe_area method that returns unobscured area of
the window, where interactive controls should be rendered.
- Reorganizes how launch screens are exported - the previous way was
incorrect and modern iPhones did not pick up the correct screens and
because of that used a non-native resolution to render the game.
- Adds launch screen options for iPhone X.
- Makes launch screens optional in the export template. If not
specified, a white screen will be used.
- Adds App Store icon (1024x1024) export option as it now has to be
bundled with the app instead of being provided in iTunes Connect.
- Fixes crash when launching games in iOS Simulator. It happened because
controllerWasConnected callback came before the engine was
initialized. Now in such case the controllers will be queued up and
registered after initialization is done.
- Fixes issue with the virtual keyboard where for some reason
autocorrection panel would intersect with the keyboard itself and not
allow you to use the top row of the keyboard. This is fixed by
disabling autocorrection altogether.
Closes#17358. Fixes#17428. Fixes#17331.
This is accomplished by setting a special value (-1) to the device variable
in the InputEvent that's being used to compare with the one received from the OS.
This special value is invalid for a regular input, so it should be safe.
Implements #17942
