[Solved]Struggling with world.setBlock changes not preserved

[lido666]

Hopefully somebody can help!

 

Struggling with world.setBlock using forge 1.7.2 and gradle, I have the following code:

 

World world = Minecraft.getMinecraft().theWorld;

world.setBlock(xPos+x, yPos+1, zPos+z, Blocks.air,0,0);

world.setBlock(xPos+x, yPos, zPos+z, Blocks.coal_block,20,20);

 

I can set blocks within my mod, but the blocks reverts back to what they were before the .setBlock command (ie. if you try and use an item on them).  when I exist a world, and return, my changes are gone. 

 

Rather than using custom blocks, I want to use standard inventory for the time being (unless I must create a custom block)  ?  If this something linked to client side changes to server side changes?

 

 

It appears that I am making changes to a client side (cache) which is then being overidden by the server side cache? 

 

Any suggestions please ?

 

Many thanks Lido666

I am calling this from my class which is triggered from the event_bus, eg

 

@SubscribeEvent

public void onPlayerUpdate(LivingUpdateEvent event)

 

Where should I setup my event bus from to receive play events ?

 

Many thanks in advance

Thanks for the quick response.  Play events are exactly how you described them above.

 

I create the hook on to the event bus using:

 

@EventHandler

    public void init(FMLInitializationEvent event){

       

    // We add the command below (and a new ItemPickupHandler class), all events now go in that class

    MinecraftForge.EVENT_BUS.register(new ItemPickupHandler());

 

It is from this class that I am calling the .setBlock

world.isRemote returns true.

 

I have setup client and server side classes using:

    @SidedProxy(clientSide = "com.example.examplemod.proxy.ClientProxyClass", serverSide = "com.example.examplemod.proxy.ServerProxy")

    public static proxyCommon proxy;

 

Do I need to register my event_bus handler from the class ServerProxy ?

 

Many thanks in advance

Thank you.  Even when using 'onLivingUpdateEvent',  I only ever get events which are remote.  Used the code below, and only received remote events, even when mining, jumping,  crafting.    Any suggestions please?

 

 

@SubscribeEvent

public void onLivingUpdateEvent(LivingUpdateEvent event)

{

world = Minecraft.getMinecraft().theWorld;

if (world!=null) System.out.println("I am on server" + world.isRemote);

}

Don't use Minecraft class, use the given event instance.

Thank you.  After changing definition from minecraft to world = event.entity.worldObj;  started to see events from the server.

 

Kind Regards
