Scenario: In LoadGame Lobby screen, the difficulty toggle group is showing multiple choices, but actually only one valid is working.
The reason is, in the Lobby screen Initialization code will set the difficulty = 0, and each time the player changes a map in the selection, the toggle group control is not resetting the difficulty buttons to disabled state.
How fix:
Add a new method to ToggleGroup class: setSelectedOnly, which will disable all other buttons and then set the selected button.
Note:
During the game loading time, the client is loading the map, and send a NetPack to server: LobbySetMap, and send a NetPack to Interface: LobbyUpdateState.
In the LobbyUpdateState it sets the map difficulty.
On Android calling `SDL_RenderSetLogicalSize` with dimensions having a different aspect ratio than the screen will cause letterboxing with blinking garbage data in that areas (instead of having black bars). This is annoying and makes the game really hard to play.
This change will make sure that on Android `SDL_RenderSetLogicalSize` will always be called with dimensions where the aspect ratio is the same as the screen to make sure there is no letterboxing.
The only problem with this is that during drawing the adventure map nothing will clear out the areas that would have been letterboxes, so there is an added explicit clear screen command for `totalRedraw()`.
The changes are only applied to Android builds in order not to affect PC builds - but some changes, especially clearing the screen could be easily added to the PC builds as well
When winning the campaign there is a lock that waits for the old server to stop before allowing to continue with restarting the server. While the lock was released on PC builds as the server runs differently on Android this was missed making campaigns always hang the app when you win.
This change adds a new native method that can be called from the Android app to signal that the server has stopped, so the client can continue with requesting a new server and showing the new campaign scenatio screen.
Note: this change alone doesn't fix the bug but it's required for a fix on vcmi-android's side. It doesn't break anything and can be merged before the vcmi-android changes
Defect:
After my previous change that enabled map layer (`CAdvMapInt`) to listen to all mouse move events via `strongInterest` bool, I noticed that there are a few scenario that start scrolling the map unexpectedly. The two that were the easiest to reproduce were using keyboard arrows to move the hero or dimissing a popup dialog.
I traced this down to unexpected mouse move event (`SDL_MouseMotionEvent`) that SDL seems to dispatch in this situation. The windowID that comes with the event in this scenario is 0 (so no window with mouse focus). I don't know why SDL dispatches this mysterious (to me) mouse move event in that case (note that there is no actual mouse movement in either repro case).
Fix:
Don't handle the mouse move event if the windowID of the mouse motion event is 0.
Notes:
Impacts scrolling of the game map. Did some play testing and didn't notice the scrolling not working when expected. The two specific cases where the map would scroll unexpectedly (move a hero with keyboard arrows or dismiss a popup dialog) no longer move the map.
In fullscreen mode, when the adventure window size does not fill the entire monitor (leaving black bars on each side), mouse movement is ignored in these areas. This results in difficulty scrolling the map in fullscreen mode, since you have to be exactly within [0,15] of the edge of the adventure window.
Fix:
Have the adventure map element, CAdvMapInt, subscribe to all mouse move events by setting the `strongInterest` bool to true. This will extend the scroll region to [min, 15], eliminating the dead mouse move space on the side of the window.
Notes:
Impacts adventure window mouse move event handling. Manually validated the scrolling the map now works without having to precisely aim for the edge of the window.
* Fix wrong save files shown in HotSeat mode
Previous condition only checked for players' connection ID. HotSeat mode does not use multiple connection IDs, so getLoadMode() thought it was SPMode.
Now checking number of interfaces to cover offline-multiplayer.
Added else condition that covers cases "ObjectAtTile that is not enemy nor is Town nor is current Hero". This should cover all cases of friendly dwellings/mines not having the correct cursor.
Warnings fixes
* Suppress `missing-braces` for Clang

* Fixed some unused capture warnings
* Node graph initialization optimized.
* Fixed "Unathorized obstacle access".
* Pathfinding tracing disabled with ifdef.
* Misc bonus calculation optimizations.
* Removed timestamp from log lines. Date formatting eats too much CPU.

* use smart pointers for almost all widget fields
* use SDL2 texture for cursor
* a lot af small tweaks and formatting
* removed CompImage class, it is actually useless as long as regular SDLImage support margins
* CGuiHandler: use smart pointers for [push|pop]Int
We need to make sure it's not stay active during gameplay.
Proper fix would require actually removing menu interface from GH, but then GH needs refactoring too.
* Changed most gui classes to use shared pointers
* Store and use IImage as shared_ptr
* CSpellWindow redesign
* AdventureMapClasses cleanup
* CLabel: store background as smart pointer
* Store CObjectList items as smart pointers
* Removed destroy function of list item
* Store toggle buttons as smart pointers
* Use CComponent as smart pointer
* Attempt to fix artifact merchant drawing
New features for players:
* Loading for multiplayer. Any save could be used for multiplayer.
* Restart for multiplayer. All clients will restart together.
* Loading from single save.
* Hotseat mixed with network game. Multiple players per client.
* Now connection to server could be cancelled.
* Return to menu on disconnections instead of crashes.
* Restoring of last selected map, save or campaign on next run.
TLDR on important changes in engine code:
* UI: work with server separated from UI
* UI: all explitic blitting replaced with IntObject's
* UI: all new code use smart pointers instead of DISPOSE
* Gameplay always start through lobby controlled by server.
* Threads receiving netpacks now shared for lobby and gameplay.
* Campaigns: heroes for crossover now serialized as JsonNode.
* Universities, Scholars and Witch Huts may offer new skills
* Moved encode/decodeSkill to CSkillHandler
* Refactored CSkill interface and CSkill::LevelInfo image storage
* Legacy game constants renamed to ORIGINAL_XXX_QUANTITY
Addresses several related problems:
* Propagation / unpropagation of duplicate bonuses is inconsistent, causing bugs
* Duplicate bonuses never stack, which is not always intended behaviour (e.g. multiple copies of resource generating artifacts)
* Different bonuses always stack, which is not always intended behaviour (e.g. Angel + Archangel morale bonuses)
This is addressed as follows:
* Duplicate bonuses are never eliminated during propagation/inheritance.
* Unpropagation eliminates only a single copy of duplicated bonus
* Bonus receives a new field stacking that determines stacking behaviour:
* * empty string = no stacking with duplicates (default)
* * "ALWAYS" = stacks with duplicates & everything else
* * some other value = no stacking with bonuses with same stacking value
Also Morale/Luck window now hides non-stacking bonuses.
* Indirect spell effects loading
