Hey there!

 

So I'm having an issue with returning a value of mobs nearby, however, I cannot seem to access the size of the list...

 

Here is the code for the TE:

    @Override
    public void updateEntity() {
        super.updateEntity();
        if(!world.isRemote) {
            if (true) { //todo change to work.
                this.entityMobs = world.getEntitiesWithinAABB(EntityMob.class, new AxisAlignedBB(this.getPos().getX() - 3, this.getPos().getY() - 3, this.getPos().getZ() - 3, this.getPos().getX() + 3, this.getPos().getY() + 3, this.getPos().getZ() + 3));
                if (entityMobs != null && entityMobs.size() != 0) {
                    for (EntityMob entityMob : entityMobs) {
                        if (entityMob.getHealth() <= 1f) {
                            storage.receiveEnergyInternal(PRODUCE_PER_MOB, false);
                            this.markDirty();
                        }
                    }
                }
            }
        }
    }

    public int getMonstersNear() {
        if(this.world != null) {
            if(this.entityMobs != null) {
                if(this.entityMobs.size() != 0) {
                    return this.entityMobs.size();
                }
            }
        }
        return 0;
    }

 

And storing the list globally via:

    public List<EntityMob> entityMobs;

 

And the code accessing the TE:

    @Override
    @SideOnly(Side.CLIENT)
    public void displayHud(Minecraft minecraft, EntityPlayer player, ItemStack stack, RayTraceResult posHit, ScaledResolution resolution){
        TileEntity tile = minecraft.world.getTileEntity(posHit.getBlockPos());
        if(tile instanceof TileEntityBlockMobGen){
            String strg;
            if(((TileEntityBlockMobGen) tile).getMonstersNear() == 0) {
                strg = StringUtil.localize("info."+ModUtil.MOD_ID+".noMobs");
            }else {
                strg = StringUtil.localize("info."+ModUtil.MOD_ID+".mobAmount") + ": " + ((TileEntityBlockMobGen) tile).getMonstersNear();
            }
            minecraft.fontRendererObj.drawStringWithShadow(TextFormatting.YELLOW+""+TextFormatting.ITALIC+strg, resolution.getScaledWidth()/2+35, resolution.getScaledHeight()/2-15, StringUtil.DECIMAL_COLOR_WHITE);
        }
    }

*which is in the block code*

 

Thanks,

No duh. You only count the mobs server side:

if(!world.isRemote)

 

Which means that client side, the array is null.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Packet? if you're counting with a GUI or HUD you can get the Player object, from there the World from the Player, from there count nearby entities. Even if it's a TE you should be able to get that info if you pass it in the constructor. All entities should be duplicated to the clients so counting them should be easy either side
