Thank you for reply, actually I already did "ServerWorld.spawnParticles" but result was same. I'm trying to use PlayerTickEvent to spawn particle using ClientWorld.addParticles... But to me it's odd because "SwordItem.onEntitySwing" could show particles for everyone on a server using ClientWorld.addParticles. This is also what I want to know.

Ding, I assumed that you use JDK15 instead of 1.8. Check your project property if Java Compiler/Build path is pointing "real" JDK 1.8 instead of JDK15. You get this error "java.lang.NoClassDefFoundError: jdk/nashorn/api/scripting/NashornScriptEngineFactory" because this class does not exist anymore in JDK15.

player.getEntityInWorld(); That function does not exist.

I can't use !world.isRemote since I cast world into ClientWorld in order to call implemented addParticle (ServerWorld.addParticle does not anything according to documentaiton). I also tried ServerWorld.spawnParticle, but result was same.

The folder structure is correct, but I see a bunch of exception in the console. Can I see all of the exception messages? Also what would happen if you execute "gradlew build"? And you installed Java 1.8, right?

[1.16.4] Hello, I'm pretty new to forge modding.

(Using LivingJumpEvent) I also made a mod which spawns particles when player swing a special sword, but everyone can see the particles. (Using SwordItem.onEntitySwing) I don't quite get difference between those two. Can anyone tell me why there's gap on those? Here's the event subscriber for j
