|
* Add bold, italic and monospace font styling for HUD text elements (#11478)sfan52021-07-27
| | | Co-authored-by: Elias Fleckenstein <eliasfleckenstein@web.de>
* Minimap as HUD element with API controlPierre-Yves Rollo2020-10-04
| | | | | | | Features: * Define Minimap available modes (surface/radar, scale) from Lua, using player:set_minimap_modes() * New HUD elements for displaying minimap with custom size and placing * New minimap mode for displaying a texture instead of the map

* Fix precision not working in hud_change (#10186)Lars Müller2020-08-12
|
* Add support for statbar “off state” icons (#9462)Wuzzy2020-05-11
| | | | | | | This adds support for optional “off state” icons for statbars. “off state icons” can be used to denote the lack of something, like missing hearts or bubbles. Add "off state" textures to the builtin statbars. Co-authored-by: SmallJoker <mk939@ymail.com>

|
* Optimize headers (part 2) (#6272)Loïc Blot2017-08-18
| | | | | | | | | | | | | | * Optimize headers (part 2) * less debug.h in headers * less remoteplayer.h for everybody * Cleanup (part 2) * camera.h: mesh.h * mapgen.h: mapnode.h * serverenvironment.h: mapblock.h * nodedef.h: shader.h
* Modernize various files (part 2)Loic Blot2017-08-18
| | | | | | | | | * range-based for loops * emplace_back instead of push_back * code style * C++ headers instead of C headers * Default operators * empty stl function
* Irrlicht cleanup: cleanup various object to use RenderingEngine (#6088)Loïc Blot2017-07-02
| | | | | | | | | | | * Irrlicht cleanup: cleanup various object to use RenderingEngine * CAO doesn't need scenemanager in addToScene * Camera doesn't need VideoDriver pointer or SceneManager in constructor * Hud doesn't need driver & scene manager in constructor * Hud doesn't need scenemanager pointer * Tile.h doesn't need IrrlichtDevice header (just SMaterial) * WieldMeshSceneNode: only take scene, we always use scene root node as parent
* Isolate irrlicht references and use a singleton (#6041)Loïc Blot2017-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add Device3D class which will contain IrrlichtDevice interface move getSupportedVideoDrivers to Device3D Add Device3D singleton & use it in various places Rename Device3D to Rendering engine & add helper functions to various device pointers More singleton work RenderingEngine owns draw_load_screen move draw functions to RenderingEngine Reduce IrrlichtDevice exposure and guienvironment RenderingEngine: Expose get_timer_time() to remove device from guiEngine Make irrlichtdevice & scene manager less exposed * Code style fixes * Move porting::getVideoDriverName, getVideoDriverFriendlyName, getDisplayDensity, getDisplaySize to RenderingEngine Fix XORG_USED macro -> RenderingEngine + create_engine_device from RenderingEngine constructor directly * enum paralax => enum parallax
* hud.cpp: fix wrong indent in drawItemLoïc Blot2017-06-19
|
* Cpp11 initializers 2 (#5999)Loïc Blot2017-06-17
| | | | | | | | | | * C++11 patchset 10: continue cleanup on constructors * Drop obsolete bool MainMenuData::enable_public (setting is called with cURL in server loop) * More classes cleanup * More classes cleanup + change NULL tests to boolean tests
* Use thread_local instead from some static settings (#5955)Loïc Blot2017-06-11
| | | | | thread_local permits to limit variable lifetime to thread duration. Use it on each setting place which uses static to cache variable result only for thread lifetime. This permits to keep the same performance level & reconfigure server from MT gui in those various variables places. Add thread_local to undersampling calculation too.
* Do not shade inventory items with textures (#5869)Dániel Juhász2017-06-01
| | | | This commit restores the old behavior: if an inventory item has an own inventory texture, it will not be shaded.
* Time: Change old `u32` timestamps to 64-bit (#5818)SmallJoker2017-05-26
| | | | MacOSX build fix + cleanups
* Add option to use neither node highlighting nor outliningezhh2017-05-15
|
* Clean up getTime helpersShadowNinja2017-04-28
| | | | | | This increases size of the getTime return values to 64 bits. It also removes the TimeGetter classes since the getTime functions are now very precise.
* Soft node overlay (#5186)Dániel Juhász2017-04-21
| | | | This commit adds node overlays, which are tiles that are drawn on top of other tiles.
* Hardware coloring for itemstacksDániel Juhász2017-04-08
| | | | | | | | | | Adds the possibility to colorize item stacks based on their metadata. In the item/node definition you can specify palette (an image file) and color (fallback color if the item has no palette or metadata). Then you can add palette_index to the metadata. Dropped itemstacks with different colors do not merge.
* Environment & IGameDef code refactoring (#4985)Ner'zhul2017-01-09
| | | | | | | | | | | | | | | | | | | | | * Environment code refactoring * Cleanup includes & class declarations in client & server environment to improve build speed * ServerEnvironment::m_gamedef is now a pointer to Server instead of IGameDef, permitting to cleanup many casts. * Cleanup IGameDef * Move ITextureSource* IGameDef::getTextureSource() to Client only. * Also move ITextureSource *IGameDef::tsrc() helper * drop getShaderSource, getSceneManager, getSoundManager & getCamera abstract call * drop unused emerge() call * cleanup server unused functions (mentionned before) * Drop one unused parameter from ContentFeatures::updateTextures * move checkLocalPrivilege to Client * Remove some unnecessary casts * create_formspec_menu: remove IWritableTextureSource pointer, as client already knows it * Fix some comments * Change required IGameDef to Server/Client pointers * Previous change that game.cpp sometimes calls functions with Client + InventoryManager + IGameDef in same functions but it's the same objects * Remove duplicate Client pointer in GUIFormSpecMenu::GUIFormSpecMenu * drop ClientMap::sectorWasDrawn which is unused
* Halo: Highlight selected faceRealBadAngel2016-11-12
| | | | | This is a slightly modified and cleaned up version of #3774 by RealBadAngel. By sofar: Remove color change (just make it lighter) and some minor cleanups.
* Escape more strings: formspecs, item descriptions, infotexts...Ekdohibs2016-04-24
| | | | | | Also, change the escape character to the more standard \x1b Thus, it can be used in the future for translation or colored text, for example.
