📋 About This Mod
!(https://i.imgur.com/KyeiwRx.png) "My analysis of historical data suggests an 97.34% probability that you are aware of my birth on your planet, and my rebirth into beauty on Citadel Station." -System Shock 2 Citadel is a Library mod required for advanced animations and entity properties in 1.14 and beyond. Citadel, being a Library, does not add many features by itself, but rather provides a frame work for other mods when it comes to animating entities, loading .tbl Tabula and .obj Waveront models, and for keeping track of entity properties. Citadel's predecessor, LLibrary, will no longer be updated from 1.12.2, and from now on all of my mods will use Citadel. Citadel's code base is largely derived from LLibrary, and the code is used with permission from Gegy1000, the maintainer of LLibrary and its author in recent versions. In versions 1.6.3 and above, there is also a config option for changing the cap on how many mobs spawn on chunk generation. This is useful when used with the many mob mods that require Citadel, as without changing this they can make it quite difficult to find vanilla mobs. Developers who want to use Citadel can read (https://github.com/Alex-the-666/Citadel/wiki/Getting-Started).
Description Citadel is a block protection mod that provides a level of protection relative to the material used to create the protection. There are two linked concepts that Citadel uses to provide protection - reinforcement and security level. Citadel Natural Reinforcements Have a hardcore sever where you want everything to be tough? Well Citadel is able to naturally reinforce certain blocks. This allows you you to make mining any certain kind of block you want take a certain amount of breaks to break the block. Example: you have stone and a player comes across it. Citadel says that it takes 4 breaks to really break stone. The player must break the same stone block 4 times before it disappears and drops a cobble stone. Reinforcement A reinforcement provides protection to a block from being broken. Each type of reinforcement material provides a different number of protections, with a protection being used up during each block break event. The strengths of stone, iron, and diamond reinforcement are 25, 250, and 1800 respectively. For example, if you protect a glass block with an iron ingot, you will have to break the glass block 250 times before it is actually broken. Security Level A reinforced block which is considered securable (configurable but includes anything openable like a door or fence gate, and any containers like furnaces and chests) can also have its allowed access limited to the individual which placed the block or a group to which they belong. Groups Players can create groups and add members to them. Groups have the following hierarchy: Owner: Can delete, transfer, add and remove mods, allow and disallow members, modify reinforcements, and set password. Moderator: Can allow and disallow members, modify/bypass, and add new blocks to group. Cannot delete or transfer group, and cannot add or remove mods. Member: Can only access and open things like doors, chests, etc. Cannot modify or bypass reinforcements, and cannot edit group. Modes Reinforcement: In this mode, a player can reinforce already existing blocks. To start, type /ctreinforcement followed by an optional security level. If no security level is specified, blocks are secured at the private level. Once in this mode, hold a valid reinforcement material in your hand and click on the block to reinforce it. Single block mode: To provide feature compatibility with LWC, you can enter single block reinforcement mode by typing /ctprivate, /ctgroup, or /ctpublic. These are aliases for /ctreinforcement followed by the corresponding security level, with the exception that once a block is reinforced, reinforcement mode is disabled. Fortification In this mode, a player can place blocks that are reinforced. This is useful for building reinforced structures, or placing a lot of reinforced securable blocks. To enter this mode, hold a valid reinforcement material in your hand and type /ctfortify followed by an optional security level. If no security level is specified, blocks are secured at the
