Hey guys,

I managed to find the arrows I am looking for. My problem right now is that I am having problems to find the block the arrow is stuck to, from the EntityArrow. I got this right now, but my way of finding the correct BlockPos is.. total bullshit :'D

 

@SubscribeEvent
public void worldTick(WorldTickEvent event)
{
		for (Object obj : event.world.loadedEntityList) {
		if(obj instanceof EntityArrow)
		{

			NBTTagCompound compound = new NBTTagCompound();
			EntityArrow arrow = (EntityArrow) obj;
			arrow.writeToNBT(compound);

			if(compound.getByte("inGround")==(byte)1)
			{
				compound = arrow.getEntityData();
				if(!compound.getBoolean("checked"))
				{
					BlockPos pos = new BlockPos(Math.floor(arrow.posX),Math.floor(arrow.posY),Math.floor(arrow.posZ));
					event.world.setBlockState(pos ,Blocks.iron_ore.getDefaultState());
					compound.setBoolean("checked", true);
					arrow.setDead();
				}
			}
		}
	}
}

aight will do so. any ideas for the check which block is my friend?

nevermind. just found out what the tiles mean.

For anyone who cares.

The boolean flag is because setDead would make it tick one more time, so i set a checked flagg

 

@SubscribeEvent
public void worldTick(WorldTickEvent event)
{

	for (Object obj : event.world.loadedEntityList) {
		if(obj instanceof EntityArrow)
		{


			EntityArrow arrow = (EntityArrow) obj;
			try {
				Field tileY = EntityArrow.class.getDeclaredField("yTile");
				tileY.setAccessible(true);
				if(tileY.getInt(arrow)==-1) continue;
				NBTTagCompound compound = arrow.getEntityData();
				if(!compound.getBoolean("checked"))
				{
					Field tileX = EntityArrow.class.getDeclaredField("xTile");
					Field tileZ = EntityArrow.class.getDeclaredField("zTile");
					tileX.setAccessible(true);
					tileZ.setAccessible(true);
					System.out.println(tileX.getInt(arrow));
					System.out.println(tileZ.getInt(arrow));
					System.out.println(tileY.getInt(arrow));
					BlockPos pos = new BlockPos(tileX.getInt(arrow), tileY.getInt(arrow), tileZ.getInt(arrow));
					event.world.setBlockState(pos ,Blocks.iron_ore.getDefaultState());
					//compound.setBoolean("checked", true);
					arrow.setDead();

				}
			} catch (Exception e) {

				e.printStackTrace();

			}


		}
	}
}

jup. changed that
