Holding Right Click Detection

About

This method allows you to detect when player is "holding" right click, using a carrot on a stick.

Note: I will be referring to "carrot on a stick" as "coas" from now on

Result

A simple spell casting system where a spell will be cast when the player holds right click for a period of time

Concept

To detect when player is holding right click, you need to know when player right clicks coas twice within a time threshold.
Because Minecraft takes in coas input every 4 tick, a right click is considered continuous if it's performed within 5 ticks of another click.

Implementation

1. Setup scoreboard objectives

#[setup]

#> This objective is used for detecting when the player is right clicking.
scoreboard objectives add <coas> minecraft.used:minecraft.carrot_on_a_stick

#> This objective will alway be more than 0 when the player is holding right click
scoreboard objectives add <timer> dummy

2. Detect right click

#[main]
execute if score @s <coas> matches 1.. run function [coas/reset_timer]

3. Detect holding right click

#[main]

# Decrease <timer> by one until it hits 0
scoreboard players remove @s[scores={<timer>=1..}] <timer> 1

# If <timer> is more than 0, we know that the player has right clicked within the last 5 ticks.
# (Since <timer> decrease by 1 every tick and every time a right click is performed <timer> is set to 5 again.)
execute if score @s <timer> matches 1.. run say Player is Holding Right Click!

#[coas/reset_timer]

# Set <timer> to 5 and <coas> to 0
scoreboard players set @s <timer> 5
scoreboard players set @s <coas> 0

5. Conclusion If <timer> is more than 0, we know that the player has right clicked within the last 5 ticks, since <timer> decreases by 1 every tick, and every time a right click is performed <timer> is set to 5 again.
We can use execute if score @s <timer> matches 1.. to know if <timer> is more than or equal to 1.
