hexahedra's Issues
Player models
Rudimentary support for player models; no animations or skinning, just a static 3D model. (Depends on #7.)
Items
Basic support for items:
- Server-side definitions sent to the client on login
- Lua classes to manipulate items and item definitions
- Hotbar support
Window is very slow to move around
Window manager Xfwm 4.11, compositing enabled:
This is xfwm4 version 4.11.1 (revision 2b800f4) for Xfce 4.10
Compiled against GTK+-2.24.23, using GTK+-2.24.23.
When moving the window (even while in menu) using mouse, the window will lag behind and move in a sluggish way.
Chat
Allow players to press T and open a chat window.
Everything is black
Everything is black.
I have AMD Radeon HD 7700 Series on Windows 7. If you need more information please let me know.
Use shaders
The OpenGL fixed function pipeline functions are deprecated. The sooner we move everything to shaders, the better. (This will break OpenGL 1.5 compatibility, but that's no big deal.)
Compilation errors on Xubuntu 14.04
All dependencies are installed, with the PPA being used.

BTW, how do you compile and use the libraries from the Git repositories, instead of having to rely on a PPA?
Hotbar
The current hotbar implementation doesn't integrate with the entity system. Create a hotbar component that can be accessed through Lua, and synchronized with the clients.
Player hotbar configuration through Lua
The hotbar can be configured over the network already, but there's no Lua interface for it yet.
Fresh install raises assert in client
When starting a debug build client in single-player mode for the very first time, it asserts and quits. But it works just fine after a restart.
Packaging
- An application icon
- A desktop file and rpm/deb package for Linux
- A resource file and NSIS installer for Windows
manpages outdated
'hexahedra --help' shows more information than the manpage.
The manpage for hexahedra-server does not list any options or parameters while 'hexahedra-server --help' does.
Decouple camera from player
The camera system is now hardcoded as a first-player view. Instead, the position should be fixed to a given entity (plus an offset), and the view direction can be set to either:
- Fixed yaw/pitch
- Yaw/pitch controlled by mouse
- Aim at another entity
Surface data versioning
Let the server keep a version number of each chunk surface, so it can send updates to the client only when the client's cached version is too old.
Draw materials in the UI as cubes
Materials don't have their own icons, and should be drawn as cubes in the hotbar.
Player clips into blocks above
The player can build blocks underneath itself even when there is a block directly above the player. When there are 1-3 blocks (without spaces in between) directly above the player, the player is moved upwards to the next available space with 2 empty blocks.
However when there are 4 or more blocks above the player position, the player is only moved up 3 blocks from the original position and gets stuck in a non empty space. The camera clips and only the surfaces adjacent to air are visible.
The block two spaces underneath the player (where the head used to be) is removed and the block directly above, on which the player is standing, is invisible, though the surfaces can be highlighted when moving over them with the crosshair. The player can move and falls into the void when moving off the block.
By right clicking(destroying), the player is moved upwards by two blocks. Left clicking(placing) does nothing.
Server time
The server should inform the clients of the time of day, so they can draw the sky and adjust the light levels accordingly.
Client stuck in loading screen
arch linux x86_64 gcc (GCC) 4.9.0
started server, started client, press singleplayer, short "loading..." screen, then crash

I dont know why the server can not get the lock, permissions are right :/ maybe because of the first start (.hexahedra was empty).
Players can move through glass
Highlight block under cursor
Highlight the block face underneath the cursor.
Investigate LevelDB as as alternative to SQLite
LevelDB is an embeddable key-value database. It shouldn't be too difficult to add a new save file backend and run some tests.
IQM support
IQM files are a better bet than Assimp, especially if models are being sent over the network.
Player names
Allow players to enter their name, and display this name over their heads.
We can do this in a hacky way until we have a proper login system, but the name tag should be a component in the entity system so we can reuse it for other purposes as well.
Entity system persistence
Store the state of the entity system in the database.
Application starts minimized on Win8
On startup, the application is stuck minimized in the task bar. Only happens on Win8.
New singleplayer world doesn't start generating on Win32
When starting a new world, you just hang there in the void and nothing happens. Terrain generation starts normally after restarting the application.
Thinking about... Qt!
Hi,
did you think of maybe using some (bigger) framework like Qt for hexahedra? Qt offers a lot for functionality and faster develpment. Maybe you could replace two or three other dependencies if you use Qt. It offers good cross platform developing & installing tools and lot of nice features other than gui things like network and OpenGL.
http://www.kdab.com/opengl-in-qt-5-1-part-1/
And maybe you should split the project into three seperate projects:
hexahedra-client
hexahedra-server
hexahedra-lib
It is easier to maintain and better build process via IDE. At least I couldn't get it work with kdevelop4 or netbeans.
Maybe you can think about it.
Multithreaded access to the game world
Read/write access to the game world is growing too complex and buggy. Move the access policies to separate classes, and let the rest of the application access the world data through those.
Mr. Fixit model is non-free, suggested free replacement
I see you're using Mr. Fixit as player model, which is non-free (disallows commercial use).
Mr. Fixit conceptualized, modeled and animated by geartrooper a.k.a. John Siar [email protected]
Mr. Fixit textures, normal maps and displacement by Acord a.k.a Anthony Cord [email protected]
mask textures by Nieb
Geartrooper would like to thank Stacy for her love, support and trust. He would like to thank lee salzman a.k.a. eihrul for his support and suggestions, without which much of mr fixit would not be possible.
Mr. Fixit is hereby released under the CC-BY-NC (Creative Commons Attribution Non-Commercial) license. See http://creativecommons.org/licenses/by-nc/3.0/legalcode for more info. Please contact Geartrooper for permission for uses not within the scope of this license.
But SnoutX10K is just fine, it's under CC BY 3.0 since late 2012 (originally done for BananaBread, where eihrul paid geartrooper to release it under a free license).

Issue35 opencl.cl not found problem
Compile now works, I just had to replace #include <crypto++... with #include <cryptopp... cause header files in linux are in that format. Just to mention. I will post a "how to compile" guide on arch linux the next days. It it pretty straiht forward anyways...

maybe this is a hexanoise problem, I dont know. I am just investigating a client crash problem.
Btw. http://hexahedra.net/ is mentioned in the source code, but empty, maybe redirect straight to the forums? I didn't notice them, they are a bit hidden :) They are not mentioned here on the github repo readme. Maybe add the link there and for your blog it goes the same, there are no cross-references, you have to find everything on your own.
Configure terrain generation from file
Terrain generation is hardcoded at the moment. A game designer should have the option to configure it.

Build fails. OpenCL Dependency?
I am very interested in this project and I am very happy that you are still working on this, but sadly I can not build it on my machine (Archlinux x86_64). I tried to install libcl, but it failed. Same for Travis build it seems: https://travis-ci.org/Nocte-/hexahedra/builds
I installed an OpenCL implementation now and now it builds, but USE_OPENCL is "OFF". It seems that there is a dependendy to OpenCl wheter you use it or not.
Now (after some other minor issues) my build fails with:
[ 73%] Building CXX object hexa/server/CMakeFiles/hexahedra-server.dir/main.cpp.o

Custom hitboxes
Block hitboxes are automatically generated from their shapes. It would be nice if a game designer could provide a custom hitbox. For example, it's really annoying right now to slide along a fence, because you get stuck behind the posts.
Relatives paths possible? CMake config?
This is a feature request: I think it would be nice, to have a option to just store all files and libs etc. needed for the game relative to the binary if you compile it with static linking. So you can just copy the whole directory with all the files to another pc and run the game. I know that is not the old school linux way, but better for a game. You can provide a zip file and players only unzip and run it.
Maybe this is already possible, but I need more time to investigate the CMake config and the sources.
Entity system network synchronization
The current network sync is a hacky mess. Add proper change tracking to the entity system, and distribute the changes to the clients in a more structured way. Components should have the following attributes:
- Access: some components are only for the player that owns them, and some must never be sent to anyone.
- For some components, the update rate must be inversely related to the distance.
- Not all components need a reliable transfer.
Direction of shadows not aligned with sun
The direction of block shadows does not correspond to the direction of the incoming light from the sun.
Allow games to define their own solar system
It should be possible to define the celestial bodies in setup.json, and send this info over the network. This information includes:
- Parameters of the home planet (axial tilt, latitude, rotation speed)
- Light curves of all three light types, depending on the sun's angle
- Orbital definitions of sun, moons, and planets.
Console spammed with GL_INVALID_ENUM messages
When I start HexaHedra (with --ogl2) and enter a world console gets spammed with:
An internal OpenGL call failed in RenderTarget.cpp (276) : GL_INVALID_ENUM, an unacceptable value has been specified for an enumerated argument
OS: Linux Debian Jessie
GPU: ATI Radeon HD 5670
Player starts very high above terrain
When joining a server for the first time (either single or multi player), the player starts about 8 chunks above the surface.
Server process crashes in singleplayer
On Win32, the server process crashes randomly. Stack traces look very werid, probably a problem with the crossplatform build tools. Switching to VS2013 might help.
Player keeps moving after key is released
When jumping while moving and releasing the move key while still holding the jump key, the player continues to move and jump, even though the move key is no longer pressed. Pressing any key stops the player.
Transparent parts of the chunk don't always render client-side
In the default game, some trees are missing part of the leaves. The voxel data is there, and placing/removing a block fixes the mesh.
Faces of snow blocks visible through other blocks
Some faces of snow blocks can be seen through other snow blocks or leaves.
Key press interrupts repeated jumping
Pressing any key while holding the space bar for repeated jumping interrupts the jumps.
