Here are two functions to shoot an arrow in a ModPE Script:

The first needs an entity to shoot the arrows away from, and the speed of the arrows. The speed 2 is twice as much as 1. You can choose as speed, for example, 2.5.

The second function need x, y, z and the speed and the yaw.

The yaw 0 is north and 180 is south. You can choose a yaw from 0 until 360, if you choose another yaw it counts it as long higher or lower until it is from 0 to 360.

Just paste the functions on the top of your Mod and call them whenever you need them:

function shootArrowE(entity, speedX, speedY, speedZ){

try{

var yaw=Entity.getYaw(entity);

yaw=yaw-90;

while(yaw>360){

yaw=yaw-360;

}

while(yaw<0){

yaw=yaw+360;

}

if(yaw>0 && yaw<22){

myX=-0.5;

myZ=0;

}

if(yaw>22 && yaw<45){

myX=-0.35;

myZ=-0.2;

}

if(yaw>45 && yaw<67){
