📋 About This Mod
# MessMod A minecraft mod that contains many features ranging from world manipulation and information providing to bug fixes and so on, allowing you to take more control of the game, see more information, and do some work easier. - Don't want to use "/data" to obtain the velocity of entities? With this mod, press F3 + E and target the entity, you'll find something you wanted at a corner of the screen. (Or try sidebars) - Got annoyed about flying TNTs rendered at some wrong positions? With this Mod, you will see the correct boundary boxes of these entities. - Bored with typing "/tick freeze" & "/tick step 1" over and over again? With this Mod, these operations could be finished simply via right-click if you are holding a brick or a bone. - Have broken some blocks by mistake? With this mod, it can be easily undone with the shortcut Ctrl + Z. However, that is not everything, the detailed document is on (https://github.com/lovexyn0827/MessMod). And here is a fairly simplified version (and possibly more grammatical version) of the complete document. ### Highlights - More accurate hitboxes than ones on the vanilla client. - Tool items which makes using `/tick` more convenient. - Real-time display of entity information. - Controlling the game at the level of the source code. - Multifunctional accessing paths. - 8 easy-to-use renderers (see below). - Exporting given areas as a new save. - Undo / Redoing changes to blocks with `Ctrl + Z` and `Ctrl + Y`. - Chunk grids. - Lazy loaded chunk simulation. - And more... ### Requirements - Fabric Loader 0.8.0+. - The fabric-carpet by gnembon. (Strongly recommended, but not necessary) - Minecraft 1.16.4/1.16.5/1.17.1/1.18.2 - Everything the Minecraft requires. ### A list of commands ##### `/accessingpath` Manage custom nodes in accessing paths. (Some other features may be introduced in the future.) ##### `/countentity` Counts entities, especially stacked ones, in a easier way. ##### `/ensure` A block state checker to check if a block is rendered wrongly. If you got annoyed with "ghost blocks", it may be helpful. ##### `/entityconfig` Currently, the command can only make some entities can/cannot step on blocks directly, more features may be introduced in later versions. ##### `/entityfield` Access some Java fields of entities, using reflection. Deobfuscation is supported if the mapping is loaded. ##### `/entitylog` An entity logger is, in other words, a simple tool that obtains some data from some specified entities and writes them to a file. ##### `/entitysidebar` Manage the information lines in the entity sidebar, where you can see how something you have subscribed changes. ##### `/explode` Something even more interesting but useless, it can do nothing but cause some explosions. ##### `/exportsave` Export some given areas as a new save. ##### `/freezentity` Pause|continue processing selected entities. It can be used to simulate lazy loaded chunks. ##### `/hud` Manager custom lines in HUDs. ##### `/lag` Freeze the game. ##### `/lazyload` Simulate lazy loaded chunks. ##### `/logmovement` Subscribe some entities to see how they are pushed by pistons, shulker boxes and shulkers. ##### `/logchunkbehavior` Record some events related to chunks (e.g. loading, unloading and generation), which may be useful in some special researches. ##### `/logpacket` Listen to packets between the server and the client(s). ##### `/messcfg` Configure some features of the Mod (a detailed list of the supported options could be found in the next section). ##### `/modify` Modify some properties of entities. That is similar to `/data` and `/entityfield`, but much easier to use. ##### `/moventity` Move an entity, in whatever way you want. ##### `/namentity` Name or rename some entities without anvil and naming tags. ##### `/partlykill` Kill a part of selected entities instead of all of them. ##### `/poi` A POI (a.k.a. Point of Interest) scanner and editor. ##### `/raycast` Show the detail of raycasts, visually if you want. If you wonder what would happen if an ender pearl skims the surface of blocks, it may be useful. ##### `/repeat` Repeat the execution of a command for some times. ##### `/ride` Make some entities ride a vehicle. ##### `/rng` Do some RNG manipulation. ##### `/setexplosionblock` What would it be like if the explosion replace the broken block with diamond blocks instead of air? That will give you the answer. ##### `/tileentity` Access the data of block entities, including adding, removing, reading, and editing (in this case \/data is more appropriate). What if a dropper has a block entity of a campfire? ### Options (or rules) The following options could be set with the command `/messcfg <option> <value>`. Hope their names are understandable enough. - accessingPathInitStrategy - allowSelectingDeadEntities - allowTargetingSpecialEntities - antiHostCheating - attackableTnt - blameThreshold - blamingMode - block
