中文介绍：[GitHub](https://github.com/WhiteElephant-abc/datapack/tree/main/datapack-function-library#%E5%89%8D%E8%A8%80) | [MC 百科](https://www.mcmod.cn/class/17244.html) # Preface *This datapack is licensed under the [GNU LESSER GENERAL PUBLIC LICENSE](https://www.gnu.org/licenses/lgpl-3.0.txt "Go to this open source license page").* **This datapack provides developers with some practical functions (and some dialogs), compatible with all versions of Minecraft (except for versions that cannot install datapacks).** **However, due to the large number of commands involved in the datapack, lower versions may not be able to use all functions. The applicable versions of all functions will not be specified below.** **Please install the resource pack at the same time to use localized content (v3.2+). Otherwise, the datapack language will default to zh_cn.** **The mod version of this datapack is packaged through Modrinth, and the content is exactly the same as the datapack version, but it is not necessarily the latest version. Please try to use the datapack version.** **This datapack provides a `dfl:dfl_enable` function, which can set the score of all entities in this scoreboard to 1, which is convenient for datapacks or mods that depend on this datapack to detect whether this datapack is loaded.** **Example:** ```mcfunction #Execute when the datapack is loaded: scoreboard objectives add dfl_scoreboard dummy scoreboard players set dfl_enable dfl_scoreboard 0 #If not loaded: function dfl:dfl_enable execute unless score dfl_enable dfl_scoreboard matches 1 #If loaded: function dfl:dfl_enable execute if score dfl_enable dfl_scoreboard matches 1 ``` **Note: Some functions have "prerequisite functions" attached to their usage. These functions must be executed once before executing them.** **Some function usages are followed by `{xx:"xx"}`. These functions are [macro functions](https://zh.minecraft.wiki/w/Java%E7%89%88%E5%87%BD%E6%95%B0#%E5%AE%8F). When using them, you need to pass parameters through `{:""}` (the parameters in the usage are the recommended parameters tested by the author during development, or the parameters used by the author for testing). The parameter name (such as num) is expressed as: {num} in the text. The parameter format can refer to the function usage, and special formats will be explained.** If you encounter any problems, please click [here](https://github.com/WhiteElephant-abc/datapack/issues/new/choose) to give feedback. --- # Function Description ## Start Functions in this category are recommended to be executed when the datapack is loaded (reloaded). ### Disable Special Damage Function usage: `/function dfl:start/disable_special_damage` - Fall damage; - Fire damage; - Freeze damage; - Drowning damage. ### Fix the respawn point to 0 0 Function usage: `/function dfl:start/set_world_spawn` - Set the world respawn point to 0 0 0; - Set the respawn point radius to 0; - At this time, the player will be fixed to respawn on the highest block at coordinate 0 0. ### Enable death leaderboard Function usage: `/function dfl:start/show/enable_death_scoreboard` - Create a scoreboard item named death; - The number of deaths will be displayed on the right side of the screen; - The number of player deaths is sorted from high to low; - Note: The death leaderboard will not be displayed when it is first enabled, and it will be displayed only after any player dies. ### Display player health Function usage: `/function dfl:start/show/display_health_below_name` - Create a scoreboard item named health; - The player's health will be displayed below the player's ID; - It will not be displayed if the distance is slightly far (only the player's ID is displayed); - Note: When it is first enabled, the health will be displayed as 0, and it will be displayed only after the value is updated (such as being injured). ### Display player experience level Function usage: `/function dfl:start/show/display_level_in_tab` - Create a scoreboard item named level; - The experience level of each player will be displayed in the Tab bar (player list bar); - Note: When it is first enabled, the experience level will be displayed as 0, and it will be displayed only after the value is updated (such as leveling up). ### Display player health bar Function usage: `/function dfl:start/show/display_health_in_tab` - Create a scoreboard item named health; - The health bar of each player will be displayed in the Tab bar (player list bar). - The effect is as follows: ![[DFL] Datapack Function Support Library (datapack function library)-Image 1](https://raw.githubusercontent.com/WhiteElephant-abc/datapack/main/datapack-function-library/README/Scoreboard_Display_List_Hearts.gif) ### Quickly create a new team Function usage: `/function dfl:start/create_teams {team_blue:"blue",team_red:"red",prefix_blue:"blue",prefix_red:"red"}` - Create two teams named {team_blue} and {team_red}; - The colors are blue and red respectively; - Disable friendly fire for players in the same team; - Players can only collide with entities not on the same team; - The player name prefixes are {prefix_blue}_ and {prefix_red}_ respectively. ## Tick Functions in this category are recommended to be executed every Tick. ### Soft ban player Function usage: `/function dfl:tick/soft_ban_player` - Note: The executor of this function must be the player to be **banned**, you can use the `/execute` command; - Realize a soft ban by continuously tp the player to 0 0 0, setting the mode to adventure, and continuously giving the player negative buffs; - Must be executed every Tick; - Example: `/execute as @a[tag=ban] run function dfl:tick/ban`.
