settings.h: added function to return all keys used in settings, and a
function to remove a setting
mods.{h,cpp}: added class ModConfiguration that represents a subset of the installed mods.
server.{h,cpp}: server does not load add-on mods that are disabled in
the world.mt file. mods are disabled by a setting of the form
"load_mod_<modname> = false". if no load_mod_<modname> = ... setting
is found, the mod is loaded anyways for backwards compatibilty. server
also complains to errorstream about mods with unstatisfied
dependencies and about mods that are not installed.
guiConfigureWorld.{h,cpp}: shows a treeview of installed add-on mods
and modpacks with little icons in front of their name indicating their
status: a checkmark for enabled mods, a cross for disabled mods, a
question mark for "new" mods
Mods can be enabled/disabled by a checkbox. Mods also show a list of
dependencies and reverse dependencies. double-click on a mod in
dependency or reverse dependency listbox selects the corresponding
mod. Enabling a mod also enables all its dependencies. Disabling a mod
also disables all its reverse dependencies.
For modpacks, show buttons to enable/disable all mods (recursively,
including their dependencies) in it.
Button "Save" saves the current settings to the world.mt file and
returns to the main menu. Button "Cancel" returns to main menu without
saving.
basic keyboard controls (if the proper widget has keyboard focus):
up/down: scroll through tree of mods
left/right: collaps/expand a modpack
space: enable/disable the selected mod
Scripts can call minetest.register_on_shutdown() to register a
shutdown hook.
Document that minetest.register_on_shutdown() callbacks may not be run
If the server crashes, it is unlikely that callbacks registered using
minetest.register_on_shutdown() will be called.
Correct lua api version number
Always update animations and attachments after the entity is added to scene client side. Fixes animations not being applied in client initialization for some reason. Attachments should be re-tested now just to be safe.
Fix a segmentation fault caused by reaching materials that didn't exist in a loop for setting texture
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
(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
