In this tutorial, we will use right-click mouse detection. If you want to learn more about how this detection works, check out this tutorial by clicking here

Before we start, get the wand that will summon fireballs using the command below

give @p minecraft:stick[food={nutrition:0,saturation:0.0,can_always_eat:true},minecraft:consumable={consume_seconds:1000000},minecraft:custom_data={Fireball_Wand:1b},minecraft:custom_name="Fireball Wand",minecraft:enchantment_glint_override=true]

Create the following scoreboard to be used as the wand cooldown

scoreboard objectives add fireball_cooldown dummy

Run this command to set a zero score in the scoreboard to avoid problems

scoreboard players set @a fireball_cooldown 0

Now it's time to set up the cooldown and run the function commands

Place two separate Repeat command blocks set to Always Active and use the following commands

execute as @a if score @s fireball_cooldown matches 1.. run scoreboard players add @s fireball_cooldown 1

execute as @a if score @s fireball_cooldown matches 40.. run scoreboard players set @s fireball_cooldown 0

The first command will run on all players (adding +1 score individually) every Minecraft tick: 20 ticks = 1 second

In the second command, we detect if the score reached 40, which in this case means a cooldown of 2 seconds

After that, the score will be reset, and therefore the cooldown to use the wand will also reset

When the click happens, the function is called and checks if the cooldown is zero to charge the attack

Here are the commands for the attack charging function

advancement revoke @s from comandos:click_fireball_attack

execute if score @s fireball_cooldown matches 0 run execute anchored eyes positioned ^ ^ ^ summon fireball run function comandos:fireball_attack_position

execute if score @s fireball_cooldown matches 0 run scoreboard players set @s fireball_cooldown 1

Here are the commands for the position detection function to summon the fireball

execute positioned 0.0 0.0 0.0 run tp @s ^ ^ ^0.1
