When I try to use the "Blue Light Saber"(id:902),BlockLauncher crashes...

Why not use

function useItem(x,y,z,itemId,blockId,side,itemDamage,blockDamage) {}

Instead of your unconventional workaround?

EDIT: also no semicolon after Player.getCarriedItem() but I always thought there was a semicolon autoinserter in the blocklauncher code interpretation system, still, you never know

You also need an entity killed handler, simply setting the victims value to a number less has a high chance of setting the value to a negative number, and this WILL ALWAYS result in a crash. After you handle negative values, and set the entity health to 0, you will notice that there are no drops from the victim. This is known, and I recommend setting the health to 1 if victims health-damage<=0, then applying withering/harming/fire onto it. Note that fire will also have a visual change, and cook animal meat drops. Some other people say that simply setting the victims health to 1 should be enough, since the punch will apply 1 more damage and kill the victim, but I have not tried this
