[1.7.10] Lightning detection

[iWasHere]

How can I tell when/where a lightning bolt strikes? I've tried basically all of the events relating to entity spawning, and none work. The only even relating to lightning seems to be when entities are struck by it. Does anybody have any idea of what I could do? Thanks in advance.

EntityLightningBolt extends EntityWeatherEffect extends Entity

public EntityLightningBolt(World worldIn, double posX, double posY, double posZ)
    {
        super(worldIn);
        this.setLocationAndAngles(posX, posY, posZ, 0.0F, 0.0F);

 

Ligtning entity has x,y,z you can easily get it from EntityJoinWorldEvent with checking if entity is lightning (and ofc. side).

 

EDIT:

Whoa (post below) - I didn't know that, sry OP.

Hi

 

I'm not sure there's an easy way to do this; although EntityLightningBolt is an "Entity", it isn't treated the same as other entities.  It gets "spawned" into its own list of weather effects.  The code is in WorldServer::

 

                this.theProfiler.endStartSection("thunder");
                int i1;
                BlockPos blockpos;

                if (this.provider.canDoLightning(chunk) && this.rand.nextInt(100000) == 0 && this.isRaining() && this.isThundering())
                {
                    this.updateLCG = this.updateLCG * 3 + 1013904223;
                    i1 = this.updateLCG >> 2;
                    blockpos = this.func_175736_a(new BlockPos(k + (i1 & 15), 0, l + (i1 >> 8 & 15)));

                    if (this.func_175727_C(blockpos))
                    {
                        this.addWeatherEffect(new EntityLightningBolt(this, (double)blockpos.getX(), (double)blockpos.getY(), (double)blockpos.getZ()));
                    }
                }

 

There is also client-side code (see S2CPacketSpawnGlobalEntity.processPacket() but I don't think it will help either.

 

I think you will probably need to use ASM+Reflection to insert your own hook in there.  That's a pretty advanced technique.

Oooooohh boy. That kinda sucks for me, just started modding a couple days ago. I guess I'll just have to make it so entities hit by lightning drop my item. Almost never happens, but hey, that's what I gotta do I guess.

 

Thanks guys.
