OpenTESArena

This release introduces several major gameplay features including enemy combat AI, leveling up, and NPC conversations. Thieving mode has been added which allows the player to pickpocket citizens and open locks. Failure may trigger a guard encounter. Shopkeepers now provide a number of services like buying and selling items, renting a tavern room, and curing diseases. (Bartering, repairing, and spellmaking will be added later) The engine now defaults to your Steam install of Arena if available. On Windows, it will also check for your GOG install of Arena. Release video is [here](https://www.youtube.com/watch?v=nyrD5UDtfJE). ## New features and changes: - Added enemy combat AI - Added experience gain and leveling up - Added inventory item equipping and dropping - Added thieving mode ("P" hotkey) - Added random enemy encounters based on player level (@Allofich) - Added guard encounters upon killing a citizen or failing thieving (@Allofich) - Added several shopkeeper services (buy/sell items, rent room, heal, cure disease) - Added citizen conversations - Implemented NPC's ability to write directions on player's automap - Added camping for a manual duration or until healed.

This release adds a Vulkan renderer for significantly improved performance over the software renderer. Voxels now combine into larger meshes to reduce the number of draw calls and collision shapes required. The lighting system has been changed from forward to tiled forward which removes the lights-per-mesh limit. This is necessary for some scenes where a single mesh might be affected by 16 or more lights. Thanks to incredible work done by @Allofich, the mystery surrounding Arena's heavy fog has finally been solved. This effect appears randomly based on weather and is supported in both renderers. Release video is [here](http://www.youtube.com/watch?v=9Wwyj75mKSk). ## New features and additions - Vulkan renderer - Must enable manually in options menu by setting Graphics API to Vulkan - Mesh combining - Changed forward lighting to tiled forward - Added classic heavy fog effect - Added floating origin to reduce Z-fighting and shimmering - Added tavern patron dialogue - Increased physics updates per frame to reduce bumpy feeling when moving - Added baseline .OBJ file format support, used with voxels - Added inverted mouselook option - Added Enable Validation Layers option (must have Vulkan validation layers installed) - Improved frame pacing - Improved high DPI support - Reduced sky mesh vertices - Slightly reduced player and citizen move speed - Updated SDL to 2.0.12 ## Fixes - Fixed swimming camera height - Fixed chasm texture bug outside city bounds - Fixed puddle rendering performance - Fixed puddles not reflecting entities in adjacent chunk ## Known issues - Ghost-behind-ghost transparency is not supported in Vulkan renderer - Walking onto raised platforms like stairsteps is unsolved - Item stacking is not implemented, bags of gold can only hold 1 gold - Shopkeeper interactions not implemented - Bow weapons don't fire projectiles yet - Outside textures and sky don't update to match weather after entering and exiting an interior - Building names for wilderness temples and in Imperial City don't match original game For details on how to get OpenTESArena running, follow [these instructions](https://github.com/afritz1/OpenTESArena#playing-opentesarena).

This release brings greatly-improved player movement thanks to the addition of [Jolt Physics](https://github.com/jrouwe/JoltPhysics). The player can now climb out of chasms, jump, and swim. Other baseline gameplay features such as hit registering, killable enemies (w/o AI), item pickup, and using keys on doors allow the starting dungeon to now be considered minimum-playable. Rendering performance is still below average and more optimizations are planned. Release video is [here](http://www.youtube.com/watch?v=dyTfo3PvmHw). ## New features and changes - Jolt Physics integration - Minimum-playable starting dungeon - Key can be obtained and used on cell door - Enemies can be killed (no AI or combat calculation yet) - Corpses and treasure can be looted (equipping not implemented yet) - Click to attack with right mouse button in modern interface mode - Citizen name generation - Citizens can be killed (crime not implemented yet) - Baseline support for original item definitions - Locked treasure chests can be bashed open - Locked doors can be bashed open (magically-locked doors not implemented) - Attribute allocation and stats in character creation (values not gameplay-functional yet) (@libertus21) - Player gold - Player can now die from lava and drowning - Player can now fall to the ground from exhaustion and may die depending on the location - Indoor walking sound and swimming sound - Swimming music - Fanfare now plays when picking up quest items (quests not implemented yet) - Player camera can now look straight up and down without breaking math (@libertus21) - VOC sound file repairing feature (data/audio/VocRepair.txt). Removes several pops/clicks in original audio, eventually to be replaced by mods - Modern interface reticle - Gameplay clock modding (data/Clocks.txt) - Convenient Windows batch file in windows/setup_OpenTESArena.bat for installing Visual Studio toolchain and building from source (@libertus21) ## Fixes - Fixed building interior variants not matching original game - Revised light strength to match original game. Some areas like the second level of Mines of Khuras define a light radius override in the original data but it was never used in Arena. This has been fixed. - Fixed diagonal wall collision - Weapon swinging is now frame-rate independent and should no longer be difficult to successfully swing above 100 fps - Fixed voxel visibility quadtree internal node calculation (press F4) - macOS build .dylibs are handled better now resulting in less chance of a crash at application start ## Known issues - Player movement may feel bumpy due to how physics resolves ground collision with several small box shapes. Combining shapes is planned in a future release. - Walking onto raised platforms like stairsteps is an unsolved problem and should be fixed in a future release - Item stacking is not implemented, bags of gold can only hold 1 gold - NPC interactions not implemented - Bow weapons don't fire projectiles yet - Puddles cause a significant slowdown due to current design for screen-space reflections - Puddles might not reflect entities in an adjacent chunk - Outside textures and sky don't update to match weather after entering and exiting an interior - Screen-space fog is not finished and appears as a low-res cube around the player - Building names for wilderness temples and in Imperial City don't match original game For details on how to get OpenTESArena running, follow [these instructions](https://github.com/afritz1/OpenTESArena#playing-opentesarena). To see what's next, check out [the roadmap](https://github.com/afritz1/OpenTESArena/wiki#roadmap).

This release overhauls the graphics code to more closely match the look of the original game. The renderer now also uses meshes, shaders, and draw calls normally found in an OpenGL or Vulkan engine. Overall FPS is below average due to draw calls not being batched yet and the rasterizer being relatively unoptimized (it was very challenging to reliably coax all compilers to output good assembly, so there is still room for improvement). One optimization of interest however is the addition of a voxel quadtree for efficiently testing visibility to the camera. Release video is [here](http://www.youtube.com/watch?v=LEjsv2AehOg). ## New features and changes - New 3D software renderer - Closely matches original game's 256 color lighting (special thanks to @Carmina16) - Improved Arena data files detection (now checks default C: Steam install on Windows) - Added exclusive fullscreen option - Added tall pixel correction option - Initial work on player attributes (@gazorpo) - Improved screenshot saving - Minor change to player movement to match original game - ARM64 macOS support - Replaced debug collision option with ghost mode that allows flying - Replaced DebugFast build config with ReleaseGenericNoLTO - Removed time scale option ## Fixes - Fixed fog color in Elden Grove and Murkwood - Fixed Ria Silmane voice not continuing in CD version - Fixed floor replacement texture when deleting voxels - Upgraded to SDL 2.0.10 to fix periodic lag caused by SDL_PollEvent() ## Known issues - Collision detection is barebones and will be improved in a later release - Puddles are unusually expensive to render due to naïve draw call synchronization - Puddles might not reflect entities in an adjacent chunk - Exterior textures and sky don't update to match weather after entering and exiting an interior - Screen-space fog is not finished and appears as a low-res cube around the player - Some building names and interiors don't match original game ---- For details on how to get OpenTESArena running, follow [these instructions](https://github.com/afritz1/OpenTESArena#playing-opentesarena).

This release focuses on improving how the game world is simulated in order to more closely match the original game. There is now a set of active chunks that are added and removed as the player moves around. Textures are now loaded into a renderer-independent format before being passed to engine systems that need them, and with the addition of texture asset references, textures are only loaded from the hard drive once they are needed (and are kept in memory afterwards). Future support for formats like PNG should also be easier to add now. New features and changes in 0.13.0: - Chunk system - Interiors "go forever" with default empty chunk - Cities "go forever" with floor wrapping - The wilderness loads by chunk IDs and can "go forever" by falling back to a default chunk when outside of the original game's 64x64 chunk area - Texture system redesign (renderer-independent TextureBuilderID, and TextureAssetReference for deferred loading) - Support for Raspberry Pi 4 (no release build yet since performance is very poor) - Fixed citizen animation RAM usage issue (no longer ~2.5 GB) - Fixed software renderer deadlock (@Alucowie) - Fixed streetlight activation updating (wilderness streetlights intentionally do not change activation state) - Citizens now only idle if the player is not moving and their weapon is sheathed, to more closely match the original AI - Revised sun and moon positions (not sure if they exactly match the original game yet, though) Known issues: - Some intro screens might be using an incorrect palette - Wilderness building names don't match original game - The game world is empty for one frame after fast travelling, especially when arriving at a city with an arrival pop-up message - The game will crash during the Ria Silmane cinematic in the CD version if it reaches the end without being skipped (related to chunk system) - Sometimes lights will not be counted as being visible to the camera (related to chunk system) - The automap colors voxels outside of city bounds that should not be considered part of the automap - The chasm wall texture of a deleted floor voxel might not match the original game - Translucent entities exhibit vertical line artifacts (related to multi-threading) - Tavern names in Imperial City don't match original game - Diagonal walls have same collision as walls For details on how to get OpenTESArena running, see the [Installation](https://github.com/afritz1/OpenTESArena#installation) section in the Readme.

Entities and objects are planned for a future release. - Sound and text triggers (drums, drips, etc., and lore text) - Night light textures on buildings - More voxel types supported by renderer (diagonals, chasms, edges) - Performance improvements for UI and software rendering - More options in options menu (collision, skip intro, fullscreen) Notes: - Level transitions are not implemented yet, so you can only explore the first level of interiors - Doors don't work yet, and their collision has been disabled Known issues: - Some raised platforms have incorrect size or height - The Imperial City palace graphic is incorrect **Update (12/29/2017)**: Added fix to Win64 build for alcOpenDevice() errors. It will attempt to continue running even if audio initialization fails. **Update (1/21/2018)**: Added macOS build (without MIDI support, so no music yet). For details on how to get OpenTESArena running, see the [Installation](https://github.com/afritz1/OpenTESArena#installation) section in the Readme.

New features in version 0.5.0: - Sound support (.VOC files) - More weapon animations - Day/night cycle (classic sky colors and times of day. Simple sun + ambient shading) - Status pop-up in game world (location, time, and date.

New features added in 0.4.0 (mostly first attempts and prototypes): - Optional modern interface mode with free-look - Weapon animations (just fists for now) - Automap - More options in options menu (resolution scale, classic/modern interface mode, field of view) This version also addresses an issue caused by how I was building WildMIDI. If you previously had an issue with missing .dlls on Windows (i.e., missing `VCRUNTIME140D.dll`), that should no longer be a problem.

For this release, I focused primarily on developing a software renderer prototype to replace my OpenCL renderer with (since OpenCL isn't really a graphics API). I intend for the rendering to be more simple so it is easier to work with, and so I can spend more time developing other parts of the program. Another important addition is the implementation of a PKLITE v1.12 decompressor for A.EXE, so more data such as locations and names can be read in at runtime. Thanks to @Dozayon for the PKLITE specification.

This release contains a couple interface changes and some stability fixes, as well as a first attempt at sprite and point light rendering. In the interest of faster prototyping, I may decide to move away from OpenCL in favor of a software renderer instead.

This is the first pre-alpha release for OpenTESArena! The project is mostly just a "tech demo" at this point, and it's not guaranteed to run, but a few of the menus already work and you can walk around in the test world. Note: the Linux packages currently require a system that is Trusty compatible. The source code requires GCC 4.9 or newer. Anyone may download the source code and build the latest version for themselves at any time. Read the installation notes [here](https://github.com/afritz1/OpenTESArena/tree/8b8698da3620f5c233dab2ffcd6a589224deca27#installation) for more information on how to get the program running. See the [issues](https://github.com/afritz1/OpenTESArena/issues) page if you find any reproducible bugs. I'm occasionally on the OpenTESArena IRC channel if you have any questions or comments.
