ItemsAdder v4.0.17

Create items, blocks, mobs, emojis, and more with automatic resourcepack generation!
Fixed Java 16 issue when using /iazip on some servers
Beta update

config changes:
- added new option in config.yml "allow-removing-old-furnitures_2_3_11" to disable or enable removal of furnitures placed before 2.3.12 update (disable it for performance)
- now you can edit default.json file freely, read more here: https://github.com/PluginBugs/Issues-ItemsAdder/issues/1193#issuecomment-921107747
- added a new special property: "CustomModelData-starting-value" in config.yml. This property allows you to decide a starting CustomModelData for the ItemsAdder custom items. This is useful to avoid conflicts with other plugins.

fixes:
- removed useless data from mobs (item lore and item display name). This will fix https://github.com/PluginBugs/Issues-ItemsAdder/issues/1170
- fixed Could not pass event PlayerTeleportEvent https://github.com/PluginBugs/Issues-ItemsAdder/issues/1169

- fixed error in console when I use /iareload https://github.com/PluginBugs/Issues-ItemsAdder/issues/1180
- fixed sounds not protected from unzip
- fixed various problems with itemframe furnitures rotations
- fixed problem (only if player has high ping) which made furnitures removed as soon as they are placed (already fixed in the past but now increased the delay)
- fixed /iareload and /iazip can be executed during fist load of the plugin generating errors
- fixed plugin can't be reloaded anymore if any uncatched exception is thrown
- automatically remove ".json" after model_path since it's not needed
- optimized resourcepack compression time (-50%)
- optimized model_path validation
- optimized namespacedID calculation (caching)
fixes:
- reduced number of threads to avoid issues on some hosting services ("OutOfMemoryError: unable to create native thread")
- fixed wrong position of solid "hitbox" with "furniture_sit" based on "item_frame" entity and 1x1 hitbox
- fixed wrong sit rotation with "furniture_sit" based on "item_frame" entity
- fixed "fixed_rotation" and "opposite_diretion" not working correctly when placing item_frame furnitures on walls
- added a check if /iazip command is called while another /iazip command is still processing




2.4.14:
new:
- added "log-loading-no-world" settings in config.yml to disable the "No world matched" warning when a populator/decorator can't be registered because no world matched the provided names

fixes:
- fixed blocks not saved correctly if you place them after /iareload: https://github.com/PluginBugs/Issues-ItemsAdder/issues/1166
- fixed "No world matched" triggered even if a world is correctly found for populators/decorators: https://github.com/PluginBugs/Issues-ItemsAdder/issues/1168
Please read the update notes before asking for support, thanks! :D

Config changes
Please read:

- removed all the mcemojis images and kept only the mc_ruby.png file.
You have to
1. delete the data\items_packs\mcemojis\ folder
2. delete the data\resource_pack\assets\mcemojis\ folder
3. and run /iazip to apply these changes (or follow the hosting tutorial on the wiki)
If you disabled the auto extract you have to delete the folder `resource_pack\assets\mcemojis` and `items_packs\mcemojis`, then copy the new folders from the downloadable zip and paste them back.
Download the zip and copy the mcemojis folder into data\resource_pack\assets\ (it only contains the mc_ruby.png file now)
Download the emoji_images.yml file and paste it inside data\items_packs\mcemojis\

- removed "ruby_sword" from categories.yml in the Armors (you have to remove it manually from plugins\ItemsAdder\data\items_packs\various_configs\ia_gui_default_categories.yml )
