Collision Detector
by DawnFelstar
Collision Detector adds a collider entity and a note block that fire trigger functions when a player enters a set area.
What it does
Creators can place collider entities with the summon command and assign them to trigger functions, so a datapack runs commands whenever a player steps into the collider's volume. A dedicated collision detector note also appears in the mod, letting a builder attach that behavior to a block. The mod targets Fabric and is published for 1.20.1 – 1.20.6, with 1.0.0 for 1.20.6 as the latest file.
Because both the server and each player's client must process the collider, the mod is installed on both sides. The source is open under the CC0 1.0 Universal license, which places it in the public domain.
Key features
Collider entities
Collider entities can be summoned with commands and set to run a function when a player enters them.
Collision detector note
A note block variant lets builders attach collision-based triggers to a block without writing an entity command.
Command-driven triggers
Trigger functions can drive any datapack command, so areas can start effects, dialogue or redstone-free machinery.

This mod will allow you to create collider entities that can then be used to trigger funciton commands adds entity collision_detector:collision_detector (note: using the summon command will not work and you will need to edit the entity with the collider command for it to work)
