Hello Guys!

 

Inside a Living Update Event, I had the following code:

 

if (ConfigValues.truesight.get() && entity.getActivePotionEffect(Effects.INVISIBILITY) != null) {
    AxisAlignedBB bb = entity.getBoundingBox();

    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.minX, bb.minY, bb.minZ, 0, 0, bb.getZSize() / 20.0);
    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.minX, bb.minY, bb.minZ, bb.getXSize() / 20.0, 0, 0);
    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.minX, bb.minY, bb.minZ, 0, bb.getYSize() / 20.0, 0);
    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.maxX, bb.maxY, bb.maxZ, 0, -bb.getYSize() / 20.0, 0);
    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.maxX, bb.maxY, bb.maxZ, -bb.getXSize() / 20.0, 0, 0);
    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.maxX, bb.maxY, bb.maxZ, 0, 0, -bb.getZSize() / 20.0);


}

 

This code basically creates a flame hitbox around entities with the invisibility effect. The code worked fine until I closed the game and reopened the game. Upon re-opening the world, I recieved the followed crash and have no clue why. None of the code should be at risk for throwing a NullPointerException:

You are most likely reaching across logical sides.

At the top of the class where I have this code I have the following annotation: 

@Mod.EventBusSubscriber(Dist.CLIENT)

 

Shouldn't this prevent me from reaching across logical sides?

Alright: I added this to the code and it still crashes, would you be able to explain why?

 

if (Minecraft.getInstance().world != null && Minecraft.getInstance().world.isRemote() && ConfigValues.truesight.get() && entity.getActivePotionEffect(Effects.INVISIBILITY) != null) {
    AxisAlignedBB bb = entity.getBoundingBox();

    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.minX, bb.minY, bb.minZ, 0, 0, bb.getZSize() / 20.0);
    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.minX, bb.minY, bb.minZ, bb.getXSize() / 20.0, 0, 0);
    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.minX, bb.minY, bb.minZ, 0, bb.getYSize() / 20.0, 0);
    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.maxX, bb.maxY, bb.maxZ, 0, -bb.getYSize() / 20.0, 0);
    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.maxX, bb.maxY, bb.maxZ, -bb.getXSize() / 20.0, 0, 0);
    Minecraft.getInstance().particles.addParticle(ParticleTypes.FLAME, bb.maxX, bb.maxY, bb.maxZ, 0, 0, -bb.getZSize() / 20.0);

}

 

I added Minecraft.getInstance().world != null && Minecraft.getInstance().world.isRemote() to make sure the Logistical Side is the Client, and it still crashes. If I change the Logistical Side to the server it just doesn't render the particles.

Thank you! Problem solved!
