[Complex] Moving Particle Projectile

1) Create an EI Item

2) Create 6 variables:

• x, y, z, world, yaw, pitch, uuid

info

The purpose of the uuid variable is to make it so it's spammable just in case you plan to make a moving projectile that stops when it comes in contact with something.

• Set the type of the variables except the "world" variable into INTEGER
• Set the type of the "world" variable to STRING

3) Go to the activator editor

4) Create the first PLAYER_RIGHT_CLICK activator

• Go to the variable update option
• add an option for all 6 variables
• set their modification type to SET
• Update value of the following variables would be
  • x : %x%
  • y : %y%
  • z : %z%
  • world : %world%
  • yaw : %player_yaw%
  • pitch : %player_pitch%
  • uuid : %rand:1|1000000%

5) Create the second PLAYER_RIGHT_CLICK activator

6) Add the commands

1) Simple Moving Particle that damages things that comes in contact with

• Go to player-direction-offset-formula to get a copy of the math formula for reference
• Decide the range and the thickness of the line
  • For example, you want the projectile to travel 20 blocks while spawning 4 particles per block. It would be 20x4 = 80 so the first command in the second PLAYER_RIGHT_CLICK will be LOOP START: 80
• Then utilize the math formula
  • After copypasting the formula, it will initially look like this, ~%math_2*SIN({player_yaw}*-1)*COS({player_pitch}*-1)% ~%math_2*SIN({player_pitch}*-1)% ~%math_2*COS({player_yaw}*-1)*COS({player_pitch}*-1)%
  • For this portion of the guide, we will be using fireworks to produce the particle line.
    • execute at %player% run particle firework ~ ~ ~ 0 0 0 0 1
  • The "2" part of the math formula above represents the distance from the main location. We will combine it with the ~ symbols so the user's coordinates will add up along with the math formula. We will be replacing the yaw pitch placeholders with the variables, yaw & pitch.
    • Why are we using item variables? To make sure that when we look or face elsewhere, the particle would still fly at the correct direction.
  • After all of that, retype the command:
    • execute at %player% run particle firework ~%math_(%for1%)*SIN(%var_yaw%*-1)*COS(%var_pitch%*-1)% ~%math_(%for1%)*SIN(%var_pitch%*-1)% ~%math_(%for1%)*COS(%var_yaw%*-1)*COS(%var_pitch%*-1)% 0 0 0 0 1

Adding Extra Effects:

Now, you want to add effects to your moving projectile. How do we do this?

Potion Effects

• Use the command:
• execute at %player% positioned ~%math_(%for1%)*SIN(%var_yaw%*-1)*COS(%var_pitch%*-1)% ~%math_((%for1%)*SIN(%var_pitch%*-1))+1.6% ~%math_(%for1%)*COS(%var_yaw%*-1)*COS(%var_pitch%*-1)% run effect give @e[name=!%player%,distance=..2] slowness 2 2 true

Damage (Rapid)

• Use the command:

• score run-block-command block:%world%,%math_(%x%)+((%for1%)*SIN(%var_yaw%*-1)*COS(%var_pitch%*-1))%,%math_1.6+(%y%)+((%for1%)*SIN(%var_pitch%*-1))%,%math_(%z%)+((%for1%)*COS(%var_yaw%*-1)*COS(%var_pitch%*-1))% player:%player% MOB_AROUND 1 DAMAGE 2

• Then afterwards, compute what DELAYTICK value you have to use.

  • Earlier, we decided to spawn 4 particles per block. So, the formula will be (20/4) and the quotient will be 5. Which means, we will use DELAYTICK 5

• Then, we will end the LOOP command with a LOOP END command
