Fixed File::GetChecksum() logging numerous errors if file open in write mode. This prevented AssetImporter scene mode from working properly.
Fixed DocConverter asserting in debug mode. Added safe IsAlpha() & IsDigit() functions to StringUtils and exposed them to script.
Removed the "None" constraint & collision shape type for editing convenience. Note: Either the SetBox() etc. functions or ApplyAttributes() needs to be called to create the initial shape. This is to prevent a dummy shape first being created on scene load, then immediately being destroyed.
Do not debug draw disabled components.
Fixed music cutting off in networked NinjaSnowWar.
Fixed signed/unsigned mismatch in LightTest script code.
Converted Drawable components to use the Enabled flag (replaces Visible attribute.)
Converted ScriptInstance to use the Enabled flag.
Converted SoundSource & SoundSource3D to use the Enabled flag.
Show disabled node/component icons in red.
Added possibility to rotate UI element contents around a pivot point. Note: UI::GetElementAt(), child elements and child element scissoring do not currently respect rotation.
Separate script object functions for file and network serialization.
Fixed crashes in some factory instantiated classes when running without all subsystems.
Fixed crash if calling BringToFront() for a detached UI element.
Always create UI root element, even in headless mode.
Do not abort binary format scene loading if loading a component fails, as it is being read from a nested buffer and we can skip to the next.
Added Extras directory for contributions which are not strictly Urho3D core.
Added OgreBatchConverter utility from Carlo Carollo, modified to use Urho3D classes to be crossplatform compatible.
Fixed initial scene resource path in editor.
Fixed loading of editor UI configuration.
Allow casting AnimatedModel & Skybox to StaticModel in script.
Warn and redirect if StaticModel::SetModel() called on AnimatedModel().
Always output material list in AssetImporter model mode.
Editor reads imported model's material list when choosing model via component edit (Configurable, can be disabled from settings dialog.)
Simplified editor config file structure.
RenderSurface can define multiple viewports.
RenderSurface viewports can be set to update when visible in the scene (default, same as previous functionality), update always, or to update only when manually queued. The last two modes are useful when rendering a scene view eg. for use in a UI widget.
Changelog:
- Urho3D engine returns proper exit code, supports window resizing and quite mode, supports setting of any log level regardless of built type.
- Change the default graphic resolution in windowed mode from 800x600 to 1024x768 which I believe should be more common now.
- Log subsystem distinguishes between standard output and standard error streams. Error log entries are sent to stderr, so even in quite mode which stops sending to stdout, the error entries would still be shown on console. This is handy to weed out mundane entries from error entries during debugging/development.
- For UI elements, only save attribute values that are different than default attribute values during save serialization.
- Misc. UI enhancement: slider supports paging on 'empty' area along the slider; scrollbar responds to the slider hover and click on 'paging' area; menu supports passing the popup state to its sibling when mouse hovering pass the sibling; (bug fix) prevent button to generate release event erroneously (click outside, drag, hover inside, then release), plus now it should behave correctly on other situation (e.g. click inside, drag outside, then drag inside again); file-selector, list view, and line edit accept keypad 'Enter' as well; cursor supports defining shape for OS mouse too when it is set to visible, new busy cursor shape; (bug fix) fix the text default attribute values for selection and hover color to match the color assigned by constructor; line edit supports double-click to select all; scrollview hides the horizontal and vertical scrollbars automatically if not needed (still does not hide correctly on a few cases though :-).
- Refactoring the scripts in Editor application to take advantage of the Urho3D UI potential and other small improvements, like: fade out the UI when moving or rotating the scene; relayout the UI element when main window resize in windowed mode; demo the usage of busy cursor when loading scene from file; modified node/component attribute values are shown with different text label color; store the configuration file in hidden folder under user home folder as per normal practice for applications runs on MacOSX and Linux platforms; use the OS mouse so the it can move freely between Editor in windowed mode and other graphical apps.
The UI attributes in *.xml files are adjusted accordingly. The most important change is, the cursor shape now uses Image resourceref instead of Texture2D.
- Refactoring to replace code constructing the empty instance with reference to static const 'empty' instance whenever it is available; refactoring to remove redefinition of VariantMap and VariantVector in Serializer.h.
- Bug fixes: prevent double posting of error messages in the log on MacOSX and Linux platforms when Urho3D exits on error; fix DumpAPI() from erroneously substituting 'doubleClickInterval' to 'floatClickInterval'.
- Added a new tool to make dumping of the Script API even easier. I have managed to initialize a minimalist engine's subsystems to start the DumpAPI() function.
Changes:
I. Build environment
1. Added new cmake definition to disable/enable Log subsystem in main's CMakeLists.txt.
2. Added setting in main's CMakeLists.txt to pass the "-D_DEBUG" compiler flags for Debug configuration build on non-MSVC compiler. At least it is needed on XCode to get verbose debug log. I assume MSVC does not have this problem.
3. Added '../Engine. to include directories in Input's CMakeLists.txt to allow Input to reference Engine class for handling of SDL_QUIT event (see V.5 and VII.1).
4. Changed cmake_gcc.sh to sed Doxyfile to exclude Direct3D9 and include OpenGL variants of the classes, assuming gcc is only for Mac OS X and Linux.
5. Changed cmake_ios.sh to sed Doxyfile to exclude Direct3D9 and include OpenGL variants of the classes.
6. Added new cmake_macosx.sh shell script to prepare cmake for Xcode in Mac OS X environment.
7. Updated Docs/Reference.dox to correct the URL to AMD's Compressonator.
8. Updated Docs/ScriptAPI.dox to reflect API changes in UI.
9. Added *.sh scripts in the Bin folder to invoke the respective demos.
II. Audio
1. Minor refactoring on Audio class: removed redundant header include, removed redundant call.
2. Corrected minor documentation typo error in Sound.h.
III. Container
1. HashMap minor optimisation: operator [] implementation would not traverse the container twice before node insertion, refactored Clear() and Sort() implementation, changed to static_cast instead of reinterpret_cast, etc.
2. HashSet minor optimisation: refactored Clear() and Sort() implementation, changed to static_cast instead of reinterpret_cast, etc.
3. List minor optimisation: refactored Clear() implementation and changed to static_cast instead of reinterpret_cast.
4. Corrected documentation error for operator > in Pair class.
5. Added new Contains() methods and renamed Print()/PrintArgs() to AppendWithFormat()/AppendWithFormatArgs (while they are still new :-) in String class. Added ToString() global function in StringUtils class to take advantage of new append methods (useful in constructing a formatted string for logging in one liner; becomes no-ops when logging not enabled).
6. Added new Remove() method in Vector and PODVector classes.
IV. Core
1. Enhanced ProcessUtils class to add native approach to detect number of Physical and Logical CPUs for iOS platform.
BUG FIX: Previous ParseArguments(int, char**) implementation assumed there were no space in the pathname which causes parsing error when it does. Fixed by enclosed the argument in quotes before appending into command line. With this fix, Ninja War demo is runable in iPhoneSimulator.
2. In StringUtils added new convenient global function to construct a formatted string, see III.6.
3. In Variant added MAX_VAR_TYPES enum for guarding a while loop.
V. Engine
1. Added pragma to suppress LLVM/Clang erroneous warnings on unused functions in APITemplates.h.

4. Refactored DebugHUD class to use the String's new append method instead of a series of strings concatenation.
5. Enhanced Engine class to make Logging an optional feature that can be turned on/off like Profiler subsystem (see I.1), only unpause the audio when it was pause by the Engine previously, no need to check for uninitialized graphics due to window was closed (see VII.1) as engine's exiting_ flag should be set when SDL quits (even by quitting the process externally).
6. GraphicsAPI minor optimisation: Add call to reserve vector to the required known size.
7. Enhanced IOAPI to add preprocessor directive to no-ops the logging functions when Logging not enabled, see I.1.

BUG FIX: On mobile devices, the CSM only has two splits. Use preprocessor directive to define the attribute as VAR_VECTOR2 instead of VAR_VECTOR4, accordingly.
BUG FIX: Previous implementation used local ray against world bounding box for RAY_OBB. Fixed by first transformed the world bounding box to local coordinate.
11. Refactored Material class to set or unset the specular_ flag without traversing the shader parameters each time.
12. Refactored Model class: added call to reserve container capacity, removed redundant call to set the number of vertex buffer to 1 (which is Geometry's default).
13. Modified OcclusionBuffer Clear() method to use post decrement.
14. Refactored Octant and Octree classes: changed to use the new PODVector Remove() method, added index_ instance variable to facilitate child octant deletion, simplified the conditional check in the Release() but still achieving the same result.
15. Refactored OctreeQuery class to reorder the condition and to use post increment.
16. Refactored ParticleEmitter class: removed redundant class forward, changed to use the other ColorFade constructor that inits both color and time, added call to reserve container capacity.

XIV. Script
1. Enhanced Addons class: removed redundant include, changed code to suppress compiler warning, exposed new String's Contains() methods to script enginei (see III.6).

2. kNet: Removed std::cout statement in the UDPMessageConnection.cpp.
3. SDL: Changed XCODE_DEBUG_CONFIGURATION to _DEBUG in SDL_uikitappdelegate.m, see VIII.2.
BUG FIX: The touch focus was always zero causing the touch event from touchpad in Mac OS X platform was not handled correctly by Input class because the GetInputInstance() method returns 0 when windowID is 0. Assign the touch's focus with current focus window ID. NOT SURE THIS IS THE CORRECT FIX THOUGH.
XVII. Demos
1. BUG FIX: TestScene.as and TestSceneOld.as assert in the btAlignedObjectArray.h. It was caused by the script trying to remove the RigidBody and/or CollisionShape while in the middle of physics collision event handling. The Bullet's assert could be observed when build using _DEBUG. Fixed by postponinig the removal to post step.
2. Enhanced the NinjaSnowWar to support no-background-music (nobgm) option.
BUG FIX: BGM was purposely not played on multiplayer mode assuming testing is done on a same test machine, however, this has caused the BGM not to be played on the genuinue multiplayer mode using different machines.

Removed unnecessary node lookup in network replication.
Added GetScene() to Component for convenience.
Added debug geometry visualization for joints.
Added nullchecks to prevent crash by calling DrawDebugGeometry() from script with a null debug renderer pointer.

Removed ambient + lit pass combining for less shader permutations, and to prime the Z-buffer with a lightweight pass in case there is a large amount of overdraw.
Moved ambient light calculation to the ambient pass vertex shader.
Added render mode toggle to the editor settings.
Note: OpenGL rendering is currently broken.

Added zone mask for drawables, allowing to select which zones they can belong to.
When zone moves or changes its bounding box, clear the cached zone from all drawables that were inside.

Added accurate raycasts for point and spot lights. Directional light now never returns a raycast result, as it has an "infinite" bounding box.
Added better debug visualization of a point light.
Reorganization of the editor script code.
Reversed node selection logic: select nodes by default, and components when Shift is held down. This is to avoid mistakenly deleting components and leaving nodes intact when intending to do a node multi-delete.
Instead of double buffered VBOs, avoid glMapBuffer & glUnmapBuffer in "discard" mode and use a CPU-side buffer instead.
Reduce UI & DebugRenderer vertex buffer size if grossly too large.
Updated documentation. Suggest AMD's Compressonator utility for normal map processing.
Added direct script access to the Controls object of Connection, instead of going through setter & getter.
Improved NinjaSnowWar controls responsiveness during low FPS, by checking for action button presses separately, and accumulating button presses for networking.
Added tracking of last assigned shader parameter per hardware register to D3D9Graphics. This allows reusing shader registers for different parameters in different shaders.
Removed the ElapsedTime shader parameter, as wrapping it is problematic depending on the calculations it would be used for.
Removed support for bool & int shader parameters from Graphics, as bool constants are not supported in OpenGL 2.0, and int parameters are not (at least currently) needed, and can lead to worse performance.
Do not render light to stencil if camera is inside the light volume.
Added optimization for directional light shadow casters that are fully occluded by another shadow caster: do not render the lit pass for them.
Removed the alpha masking hint. Alpha test no longer gives the batch a lower priority.
Optimized shaders to do more work in the vertex shader.
Deferred rendering removed, at least for now.
Switched to RGB normal maps, with specular intensity in the alpha channel. Removed NormalMapTool.
Optimization of light influence on objects by stencil masking.

The E_CLIENTCONNECTED and E_CLIENTDISCONNECTED events now also come from the Connection in question, to allow using GetSender() for convenience, instead of looking up the connection from event data.
Added simple network traffic statistics logging to Connection.
Fixed missing default arguments in the script API.
Fixed crash if a script file is unloaded while executing a script function.
Fixed Urho3D.exe not correcting the script file name to internal format (slashes instead of backslashes.)
Use black default background for the Direct3D9 window.
Refactored SendMessage API in Connection & Network, allowing the user to specify message priority.
Split Network library internal messages into 3 priority categories.
Added commented out package download test code to TestScene.as.

Added enum CreateMode to CreateChild() & CreateComponent() which replaces the "local" bool parameter.
Added possibility for client to spawn physics boxes in networked TestScene.
Removed light prepass rendering support, as it has implementation difficulties under OpenGL and is often unsatisfactory in performance and specular lighting quality.
Removed the shader subdirectories.
Added option to specify whether single-channel images are to be interpreted as luminance or alpha, when loading into a texture.
Tweaked NinjaSnowWar difficulty.
Moved CreateObject from Object to Context.
Made EventHandler & AnimationState RefCounted to simplify memory management.
Fixed deletion of object, if no shared pointer to it existed previously, and it sent an event.
Fixed threading issue with objects' static type names. Now they are defined inside OBJECTTYPESTATIC macro as well.
Fixed Engine crash when running without the script system.
Documentation update.
Moved Engine scripting initialization to a separate function. This will result in significantly smaller executable if skipped.
Fixed ErrorDialog() when called from script.
