Fix the last segmentation fault (apparently). So far attachments seem to be fully functional, although removing the parent causes children to go to origin 0,0,0 and possibly still cause such a fault (though this should already be addressed)
Fix a bug in falling code where entities get stuck
Also check if the parent has been removed server-side, and detach the child if so. Fixes children going to origin 0,0,0 when their parent is removed.
Unset all attachment properties when permanently detaching (on both the client and server). Also store less data we don't need
Create a separate function for detaching, and also update lua api documentation
When a child is detached, update its position from the server to clients. This WILL cause it to get positioned slightly differently client side, as the server attachment system only copies parent origin and knows not about mesh / bone transformation. This prevents different clients seeing the object detached in different spots which is most correct
Update the position of attached players to clients. An attached player will see himself move, but this is currently VERY ugly and laggy as it is done by the server (it probably must stay this way too)
Use a different approach for locally attached players. This allows for smooth positio transitions to work, as well at the player turning around freely. Still buggy however
Finish fixing the material color code. But it won't work until MineTest has dynamic lighting... another day another feature.
Extra checks for the bone positioning / rotation code
Many checks and consistency improvements to the client attachment code
Make a separate function for checking if a client object is attached. A more in-depth change will be needed here to fix reading of invalid pointers
Use a different method of fetching the parent. Fixes the mass segmentation faults when rendering an attachment (some still happen though)
Major change to how attachments are handled. Fix the last segmentaton fault, which was due to the parent becoming invalid while being refreshed / removed which would bause the child to remain attached to nothing. Parents remove their children when being deleted themselves and add them back when re-added. Attachments are stored inside a 2D a vector which easily allows both a child to find their parent and a parent to find its children.
Remove attachment list entry when an object is being permanently removed. Also avoid duplicate entries in this list when re-attaching the same object
The "big code comments" can now go away. Client attachments almost work properly, and I know what else needs to be done
The child ID can now be checked against the parent ID in content_cao.cpp so the parent can be detected. Actual attachment code to come
Divide attachment system between server attachments and client attachments, neither coded right now. As explained in the code comment:
// Attachments need to be handled on both the server and client.
// If we attach only on the server, models (which are client-side)
// can't be read so we don't know the origin and orientation of bones.
// If we attach only on the client, the real position of attachments is
// not updated and you can't click them for example.
New object property which allows changing the color and alpha of mesh materials. Due to the current lighting systems it doesn't work yet, but the full implementation is there
Framework for the attachment system, with no actual functionality yet
Send bone and player object to the setAttachment function in content_sao.cpp, but we need a way to translate it there and send it to the client
I will also want position and rotation offsets to be possible to apply to attachments
Network object ID from server to client. This will be used to identify the parent client-side and know what to attach to
Support for animation blending, though for some reason it doesn't work.
Don't enable animation transitions by default for many reaosons
Object property to store individual bone positions. LUA can specify a bone name followed by a bone position. No functionality yet. Bone rotation to be added in the following commit
Same system for bone rotation, plus a few other things I missed
(obj, md2 and md3 are currently allowed)
Get rid of the texture string and use the existing textures array. Segmented meshes have multiple materials, and this will allow us to texture each. Do not switch to this commit yet!
If a texture string is left empty in LUA, don't modify that material. Useful so a script can change specific textures without affecting others
Players can now be set to meshes using the following test script:
function switch_player_visual()
prop = {
mesh="player.obj",
texture="player.png",
visual="mesh",
}
for _, obj in pairs(minetest.get_connected_players()) do
obj:set_properties(prop)
end
minetest.after(1.0, switch_player_visual)
end
minetest.after(1.0, switch_player_visual)
This causes textures to be deleted before they are no longer accessed,
resulting in a segmentation fault. This needs to be rewritten in such a way
that textures are deleted when the client disconnects from a server.
This reverts commit 41c00e87d42580881d8c7001f39014814e3b55f2.
According to #253, using `/clearpassword` without an argument causes the server to crash from an assertion failure. I've resubmitted matttpt's patch as a pull request to aid in merging.
