This is a library for use on the server legitimoose.com. Many functions won’t work properly anywhere else (specifically the motion ones)!
\nThis is a library designed mostly for my own use, but it’s available in case anyone wants to use it for their own project \ud83d\ude42<\/p>\n
This library was designed to be as easy to use as possible. It focuses on functions I use often, such as raycasts and motion manipulation. Please note however that the ease of use and general applicability comes at the cost of optimisation – much of this (especially the raycast functions) could be done much more efficiently by a dedicated function.<\/p>\n
# The Functions<\/p>\n
### add_motion
\nSets the motion of the entity to their current motion plus the input vector. Takes a relative coordinate (anything that works for a teleport command works here) as “vector”. Example:<\/p>\n
“`
\nfunction serious_lib:motion\/add_motion {“vector”:”^ ^ ^1″}
\n“`
\nThis would add 1 to the motion of the executing entity in the direction faced.<\/p>\n
### set_motion
\nSets the motion of the entity to the input vector, without maintaining current motion. Other than that works the same as add_motion.<\/p>\n
### relative_tp and relative_tp_data
\nBoth teleport the player from a starting position (start_pos) to a finishing position (end_pos), maintaining their relative position to each point. relative_tp takes both fields as macros (and is fairly pointless) but relative_tp_data takes them through data storage, allowing for dynamic start and end points.<\/p>\n
“`
\ndata modify serious_lib:motion start_pos set from entity @s Pos
\ndata modify serious_lib:motion end_pos set value [0,0,0]
\nexecute as @e[distance=..10] at @s run function serious_lib:motion\/relative_tp_data
\n“`
\nThis would teleport all entities within 10 blocks so that the executing entity is positioned at 0, 0, 0, and all other entities retain their relative position to them.<\/p>\n
### raycasts
\nThese are designed for ease of use over optimisation, and are likely horribly inefficient. They work by summoning area effect clouds with specific tags when hitting things: “entity” for an entity collision, “block” for a block collision, and “end” in addition to any other tags for wherever the raycast ends (even if it didn’t hit anything.<\/p>\n
“`
\nscoreboard players set @s ray_length 100
\nexecute anchored eyes positioned ^ ^ ^ run function serious_lib:raycast\/particle\/basic {“particle”:”end_rod”}
\nexecute at @n[type=area_effect_cloud,tag=entity] run damage @n[tag=!end]
\nexecute at @n[type=area_effect_cloud,tag=block] run particle explosion
\n“`
\nThis would cast a 50 block ray from the executing entity’s eyes, damaging the first entity it collided with, and creating explosion particles if it collides with a block.<\/p>\n","protected":false},"excerpt":{"rendered":"
