[Bug] Server Disconnect when casting Lob Creeper Spell

alfredggttv opened this issue ยท 4 comments

commented

Observed behaviour

When casting "Lob Creeper" on a group of enemies, the server immediately disconnects the player with "Network Protocol Error".

Here is a clip: https://www.twitch.tv/ftb/clip/SparklingCourageousShrewThunBeast-ZzzkLmCpxcialyfU

Expected behaviour

The spell casts, and does not disconnect the player.

Steps to reproduce

  1. Equip "Lob Creeper" spell to a spellbook. The spellbook that was used was "Flimsy Journal."
  2. Cast the spell on mobs, and eventually get disconnected right as the spell connects.

Server Type

Dedicated Server

To be more specific, this part

https://github.com/Xylonity/Explosive-Enhancement-Reforged/blob/98918f8db823c476a32e582a22a9e11c53fdd5a1/src/main/java/dev/xylonity/explosiveenhancement/particle/custom/SmokeParticle.java#L19

can roll 0, resulting in this failing

(the follow-up addition in that code also potentially fail to push the value above 1 (it's an integer), if they even get called in all cases)

public TextureAtlasSprite get(int pParticleAge, int pParticleMaxAge) {
   return this.sprites.get(pParticleAge * (this.sprites.size() - 1) / pParticleMaxAge);
}

which is called from:

public void setSpriteFromAge(SpriteSet pSprite) {
   if (!this.removed) {
      this.setSprite(pSprite.get(this.age, this.lifetime));
   }
}

Thank you so much for finding this! I have submitted and issue with that mod. I appreciate it!

yeah i can reproduce this just by summoning vanilla fireballs with explosion power of 0, seems to be an issue with explosive enhancement
