Modding Help How do I stop the zbomb Projectile from harming the player?

I'm trying to convert the throwable bomb into something usable as a melee weapon/digging tool. To do that I have the bomb explode immediately after being thrown and set the ammoUsage to 0. Unfortunately, I can't seem to stop it from harming the player. Here's my code so far:

Code:

 "output" : {
     "item" : "bomb",
     "count" : 1,
     "data" : {
    "ammoUsage" : 0,
    "cooldown" : 0,
    "projectileType" : "zbomb",
    "projectileConfig" : {
        "timeToLive" : 0,
        "speed" : 25,
        "power" : 40,
        "physics" : "rocket",
       
          "actionOnReap" : [
            {
              "action" : "config",
              "file" : "/projectiles/explosions/bombblockexplosion/bombblockexplosion.config",
              "data":
              {
                "universalDamage" : false
              }
            }
      ]
  }
    }
}

Comparing the bombblockexplosion.config to the almost identical explosion from the ferozium launcher (regularexplosionfreezeuniversal.config) which doesn't harm the player, I found that the bombblockexplosion.config had a much higher explosiveDamageAmount (which I think I want) but had the universalDamage set to true (which I don't think I want).

I could increase the life and speed of the projectile so that it travels just far enough to keep the player out of the blast, but even then it could be a bit awkward to use. Any ideas on how to stop zbomb on harming the player?

 

you could set the power to 0, where do you create your projectile, in a file, with a lua script, with a magical potato?

 

Nah, while setting the power to 0 would keep usable as a digging tool it would be useless as a weapon. Also, when I create modded items my goal is to have something people can share with their friends over multiplayer, so I can't use custom lua files. Also, I can only get a magic potatoes to work with Java programs.
