Avoid many writes to disk each time the DDNet info is downloaded, i.e. each time the refresh button is pressed in the server browser, by first loading the DDNet info into memory and only writing it to disk when it differs from the current DDNet info based on the SHA256 hash.
The SHA256 is now also used to track whether the DDNet info was modified for the community filters and icons instead of using the current time for this purpose.
Closes#3941.
Initialize the HTTP client (start the HTTP thread) after initializing the network client instead of during the client interface construction. This ensures that config variables have been loaded already and the log output level is set correctly. This also means all library initialization log messages appear together in one block when starting the client.
Show an error message box and stop launching when the HTTP client could not be initialized, instead of launching but not being able to perform any HTTP requests, which causes bug reports about the serverlist being empty.
Both console and chat commands are sent to clients dynamically with respective messages, so the static lists of commands were only used for servers not making use of these messages. Instead of assuming potentially incorrect console and chat commands on those servers, the lists will now be empty for those servers.
Move the command registration from the `ddracecommands.h` and `ddracechat.h` header files to the `CGameContext::RegisterDDRaceCommands` and `CGameContext::RegisterChatCommands` functions and delete the header files. The `CHAT_COMMAND` and `CONSOLE_COMMAND` macros are removed, because they only add unnecessary indirection now. The strings `CHAT_COMMAND` and `CONSOLE_COMMAND` are simply replaced with `Console()->Register` and semicolons are added at the end of the lines.
Closes#7665.
Support adding up to three communities as favorites in the server browser. Favorites can be changed with favorite buttons which are shown in the community filter on the Internet and Favorites tabs. The commands `add_favorite_community` and `remove_favorite_community` are added to change the favorite communities via the console and for saving the favorite communities to the config file. For the favorite communities, additional tabs using the communities' icons are shown in the server browser next to the Internet, LAN and Favorites tabs. Each community tab shows only the servers from the respective community, hence the community filters UI is not shown on the community tabs but only on the Internet and Favorites tabs. The country and type filters on community tabs cover only the countries and types from the respective community. Favorite communities are added from left to right. When more than three favorite communities are added, the oldest (leftmost) favorite community will be removed from the list.
When starting the client for the first time, i.e. with `cl_show_welcome 1`, the DDNet tab will be created as the only favorite community and selected initially. The community, country and type filters are unset when starting for the first time, so the Internet tab now shows all servers per default.
When starting with a `ui_page` for a favorite community that is not configured, the page is reset to the Internet tab. This also affects those who upgrade from versions with the old DDNet and KoG tabs. The server browser is now also correctly updated when changing `ui_page` via the console.
Track country and type filters for every community separately, to avoid filters resetting when switching between community tabs or changing the community filter. The commands `add_excluded_community`, `remove_excluded_community`, `add_excluded_country`, `remove_excluded_country`, `add_excluded_type` and `remove_excluded_type` are added to change the exclusion filters via the console and for saving the exclusion filters to the config file.
Render community filters above the toolbox (filter, info and friends) tabs when on the Internet and Favorites tab, so this setting is more visible and can be changed also when the other toolbox tabs are selected.
Add icon for the none community, based on the tee country flag color. This icon is hard-coded in the client, as the none community also is, so fetching the icon from the server would be inconvenient. Load community icons already when rendering the menu instead of only when rendering the server browser, so the icons are immediately available when using the start menu.
Find tutorial server by searching for community type "Tutorial" instead of searching for "(Tutorial)" in the server name.
Avoid cleaning favorite communities and filters when there are no communities, i.e. when the DDNet info failed to be loaded or does not contain any communities, to avoid losing all favorite communities and filters in this case.
Closes#7774.
When empty PNG files are loaded, the `std::vector` for the file contents is resized to size 0, which results in undefined behavior when it is accessed with `front`.
When `io_tell` fails, i.e. returns `-1`, this was incorrectly cast to an `unsigned` and therefore caused a very large allocation and potentially crashes due to lack of memory.
Use error log level for error messages. Use info log level explicitly instead of using `dbg_msg`.
Log time taken for initialization in trace level message.
Add parameter to `shell_execute` to either start the process in the foreground or background on Windows. Previously, all processes were started in the background, because this is desired when starting the server from the client. However, this causes the graphics initialization to fail when restarting the client after updating or with the `restart` command when using Vulkan with windowed and windowed fullscreen mode.
Closes#6578.
The `bool AllowResizing` parameter is only passed to other `SetWindowParams` functions but never used in the end, as whether or not resizing is allowed is separately determined based on the value of the `int FullscreenMode` parameter.
Instead of cleaning the countries/types filters based on all available communities' countries/types, only consider the countries/types of currently selected communities. Ensure countries/types are always cleaned when updating the server browser filter in the UI. This fixes that countries/types which are not available for the selected communities were still affecting the server filtering, causing no servers to be shown in some cases.
Closes#7847.
To simplify the usage of the demo recorder, parameters are added to the `IDemoRecorder::Stop` function to control whether the demo file is removed or renamed when stopping the recording.
Ensure demo files of the replay recorder are always removed (except on crashes). The temporary replay demos were previously not removed when being disconnected from a server.
Fix auto demos being stopped and restarted when enabling replays in the settings menu. Now only the replay recorder is stopped/started when necessary.
Fix replay recorder being restarted when setting `cl_replay` variable with console without changing the value.
Remove unnecessary `CClient::m_ButtonRender` variable. Demo rendering is already stopped correctly when reaching the end of the demo without this additional variable.
Remove unused `CDemoRecorder::m_pMapData` variable.
Ensure that the `CHttpRequest::OnCompletion` function has finished before updating the state which is visible to other threads. Otherwise, threads may try to access the result of a completed HTTP request, before the result has been initialized/updated in the `OnCompletion` function.
Fixes warning due to invalid texture width/height being shown for downloaded skins, because the texture was loaded before the image data was initialized. Closes#7818.
Regression from #7683. Before this, the `OnCompletion` function could also modify the HTTP request's state, which was used to check if loading the skin PNG failed. Instead of doing this, a separate check is added for the skin download task to check that the PNG was loaded successfully.
Store X value (time) for all graph entries in addition to the Y value (FPS, prediction margin etc.). The `CGraph::Add` function adds values to the graph at the current time. The `CGraph::InsertAt` function allows specifying arbitrary X values, as long as the values are inserted in increasing order.
The entries are kept in a ringbuffer and old entries are recycled when it's full. The size of the ringbuffer is configurable for each graph, as the FPS graph needs significantly more buffer because values are added more often.
The scrolling speed of the graphs is fixed by specifying the maximum size of the window of values which should be displayed. For this purpose, a parameter is added to the `CGraph::Scale` function to specify the size of the window which should be rendered in the `CGraph::Render` function. For the FPS graph only the last second is rendered, so small spikes are still noticeable. For prediction and gametime margin graphs the last five seconds are rendered, which should result in a similar scrolling speed as before this change. The debug tuning graph is a special case, where the X values set manually and fixed to 0-127, same as before, instead of being based on the current time.
The graph rendering is made much more efficient by precalculating when the vertex colors need to be updated, to avoid all unnecessary calls to `SetColorVertex`. Additionally, line items are bundled together in an array to avoid calling `LinesDraw` for every individual line item.
The `CTextCursor::m_LineCount` variable is only updated after the cursor is rendered. For calculating the selection quads we need to check `LineCount` instead, which is updated while the cursor is being rendered. Regression from #7733.
The `IClient::Disconnect` function is always called at the beginning of the `IClient::Connect` function. The `IClient::Disconnect` function calls `IClient::DisconnectWithReason`, if the client is not already offline, which performs cleanup of temporary commands and demo recorders already, so the same cleanup in the `Connect` function is unnecessary. An assertion is added to ensure that the client was properly disconnected before connecting. Connecting while the client is already quitting or restarting is now prevented, as the client state cannot be changed once set to quitting or restarting.
The server community was only initialized when receiving server info. This caused servers for which no server info is received to be hidden when using the community filter. Now the community filter also works correctly for servers for which no ordinary server info is received, by initializing the community already when adding server entries to the list.
Closes#7776.
Add separate `IGraphics::LoadTextureRawMove` function with non-`const` `void *pData` argument in addition to existing `LoadTextureRaw` function with `const void *pData` argument. The former function takes ownership of the data and avoids copying the texture data into an additional buffer, if the texture data is already in RGBA format. Non-RGBA texture data always needs to be converted and therefore also copied.
The `LoadTextureRaw` function is split into smaller functions to share common code with the `LoadTextureRawMove` function. Alternatively to this, a flag `TEXLOAD_MOVE_DATA` could have been added to the existing `LoadTextureRaw` function, which would have required the use of `const_cast` to free the texture data.
Unset the assertion handler before shutting down the kernel (including graphics) and client. Otherwise the assertion handler itself crashes when assertion errors happen after the graphics/client have been destroyed.
Add color palette with up to 8 colors to editor toolbar. The palette colors work like regular color picker buttons, so they open a color picker popup on click and the value can be copied and pasted with Ctrl+Right click and Ctrl+Left click respectively. Less palette colors are shown when not enough space is available (with 5:4 resolutions).
Add color pipette which allows selecting any color displayed on the screen. Selecting a color with the pipette adds the new color to the palette and shifts the other colors to the right. The selected color is also copied to the clipboard immediately. The hotkey Ctrl+Shift+C is added to toggle the color pipette, which allows using the color pipette in popups and dialogs.
The implement this, the function `IGraphics::ReadPixel` and the command `SCommand_TrySwapAndReadPixel` are added to read a specified pixel's color from the backbuffer. Like the screenshot command, this command also requires a swap operation to be performed before the correct pixel color can be read with the Vulkan backend. The `ReadPixel` function therefore accepts a pointer to a `ColorRGBA` that will be filled after the next swap operation.
Closes#7430.
Replace linear search for free sample index with free list. This brings sound sample index allocation down to constant complexity independent of the number of allocated sounds. On average the time to allocate sound samples is reduced by around 75% (843µs down to 223µs). For perspective, the time to load all default sounds on client launch is reduced by around 15ms (although this does not significantly affect launch time due to threaded loading).
The lock needs to be owned when accessing the sound voices. Calling `IsPlaying` is redundant, as the loops effectively check whether the sample is playing.
Render one quad for each line of the text selection instead of rendering one quad per selected character.
This increases the average FPS when the console is open and all text is selected by around 10% (from around 849 to around 943 FPS) (on my machine, in release mode).
When normalizing color components in the engine graphics, round the components to the nearest integer instead of rounding down. Otherwise the color that is rendered in color pickers may be off by 1 in any of its RGB components from the color that the color picker displays as text (hex string and individual components). The slightly incorrect color can be confirmed by creating a screenshot or otherwise reading the backbuffer (planned editor pipette feature).
This should not change map rendering, since maps already store quantized RGBA values on which the rounding mode should have no effect. It may however slightly change appearance of colors in all other places (at most +1 in every RGB component).
According to the Vulkan specification, the struct `VkBufferImageCopy` is used only for `vkCmdCopyBufferToImage` and `vkCmdCopyImageToBuffer`. The variable `Region` is only initialized but not passed to either of those functions.
Consider line spacing to belong to the previous line when calculating and rendering text selection. Instead of handling spacing between entries separately in the console, also include line spacing for the last line in the height calculation. Pixel align the line spacing in addition to the font size, as previously some gaps between the entries were larger than others due to missing pixel alignment. This allows rendering the text selection in the console smoothly without any gaps between the console entries/lines.
Closes#7617.
Reduce duplicate code.
Replace `clampf` function with `NormalizeColorComponent` function that convert color component from `float` to `unsigned char`.
Use `size_t` instead of `int`.
