Ray Casting Datapack by NOPEname

-Free to use for your own projects!

-Modify it in whatever way you want!

-Requires: https://github.com/NOPEname/nn_block_tags

nn_ray

-Simple ray casting

-Advantage: low performance impact

-Disadvantage: might be inaccurate, when dealing with moving entities

-How to use:

-> add tag "nnray_target" to all entities you want to be potential targets

-> run "function nnray:cast_ray" as the source entity ("execute as [...] run function nnray:cast_ray")

-> entities hit by this ray are now marked with tag "nnray_hit"

-> the entity running the function is tagged with "nnray_source"

-> tag "nnray_head" indicates that the entity's head was hit (only makes sense for player-like shaped entities)

-> see "nnray/functions/example.mcfunction" for an example

nn_ray_advanced

-Simple ray casting + improved hitbox detection

-Advantage: Better at targeting moving entities

-Disadvantage: bigger performance impact (mostly by "nnray_advanced:prepare_tick")

-How to use:

-> add tag "nnray_hitbox" to all entities you want to be potential targets

-> run "function nnray_advanced:cast_ray" as the source entity ("execute as [...] run function nnray_advanced:cast_ray")

-> entities hit by this ray are now marked with tag "nnray_hit"

-> the entity running the function is tagged with "nnray_source"

-> tag "nnray_head" indicates that the entity's head was hit (only makes sense for player-like shaped entities)

-> see "nnray_advanced/functions/example.mcfunction" for an example
