[1.12]Destroy or Spawn Blocks

Recommended Posts

I want to create the mod that destroy or spawn blocks freely.

To reproduce destruction by right clicking a custom block, I tried following method. 

 

1.Create a custom Block, and Override onBlockActivated.

2.Create a custom Explosion class.

3.Create a custom World class, and  Override newExplosion to call the custom Explosion class.

4.In onBlockActivated,

   copy public void explode from EntityCreeper, and

   downcast worldIn(param) to the custom World class.

 

But, it is error.

 

Error Message:

net.minecraft.client.multiplayer.WorldClient cannot be cast to com.example.examplemod.CustomWorld

 

a type of worldIn is World, but there is WorldClient.

why so?

 

and,

 

Is there other best ways?

 

 

Please help me.

Why are you making a custom World class? This is almost never a good idea.

Just do the explosion from your onBlockActivated method.

Thank you for answering my questions !

 

Because I want to transform the explosion shape.

Is it possible to transform by using only param?

Change the explosion shape -> custom Explosion class.

 

Nothing about that says "I need a custom World class"

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.

So... I'm a little confused. What exactly are you trying to do? Do you have to blow the block up? Or do you just want to remove it?

Developer of Randores (adds 256^3 ores to the game) and Arcane Bags (adds ridiculous storage with ridiculous crafting recipes).

I know Java pretty well... So yeah...

This is where I'd put an inspirational and/or clever quote, but I can't think of one right now...

This is the output of the totally, 100% working compiler for my programming language, Planet9:

Beginning Compilation...
Failed compilation!
planet9.compiler.error.CompilationException: Compiler not yet implemented

    • This is my code. How can I change it to have "Hello world!" show on the screen? @Mod(Chants2.MODID) public class Chants2 { public static final String MODID = "chants2"; public Chants2(){ final IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus(); final ClientSideOnlyModEventRegistrar clientSideOnlyModEventRegistrar = new ClientSideOnlyModEventRegistrar(modEventBus); registerCommonEvents(modEventBus); DistExecutor.safeRunWhenOn(Dist.CLIENT, () -> clientSideOnlyModEventRegistrar::registerClientOnlyEvents); } public void registerCommonEvents(IEventBus eventBus) { //eventBus.register(GuiHandler.class); } } public class ClientSideOnlyModEventRegistrar { private final IEventBus eventBus; public ClientSideOnlyModEventRegistrar(IEventBus eventBus) { this.eventBus = eventBus; } public void registerClientOnlyEvents() { eventBus.register(GuiHandler.class); } } public class GuiHandler { String text = "Hello world!"; @SubscribeEvent public void onRenderGui(RenderGameOverlayEvent.Post event) { drawString(event.getMatrixStack(), Minecraft.getInstance().font, text, event.getWindow().getWidth() / 2, event.getWindow().getHeight() / 2, Integer.parseInt("33AA66", 16)); } }  
    • why do you need the JDA API in MinecraftForge?
    • you also can look at the StonecutterScreen, but basically you moved the scrolling bar via mouse scroll or mouse drag (you set the y pos where it will render in the screen), after moving you can update the screen on client then send a custom packet to the server and updating the screen there
    • You still capitalizing every word... the name sounds like it will return a ResourceLocation or the mod id, not sure because urbanxx001 didn't say what the method does can you actually explain your exact goal to us, because it can be that there is a easier way to do this
    • I've got capabilities and I was just wondering if there's a way to add a statistic with the value of that capability to the stat menu, so I can make my mod more useable with FTB quests and other similar mods which can take in a statistic to trigger an event
