Bigger TNT Explosions

[arungupta]

With Forge 1.6.4, I could easily change TNTPrimed source code and make bigger TNT explosions. I downloaded/configured Forge 1.7.10 and tried the sample mod bundled with it. How would I go about making the bigger TNT explosion with it ?

[MultiMote]

world.createExplosion(exploderEntity, x, y, z, radius, spawnParticles);

[arungupta]

Just getting started with 1.7.10 ...

 

How would I get world in the sample mod ?

 

Is the associated source code for Minecraft available somewhere ? Ability to read the source in 1.6.4 was a huge benefit.

[MultiMote]

Sources can be located at /build/tmp/recompSrc.

Or you can browse forge-1.7.10-*.jar lib in your IDE.

 

In IDEA you can press Ctrl+N and enter EntityTNTPrimed.

[arungupta]

"build" directory had only the following files:

 

build

build/.gitignore

build/natives

build/natives/libjinput-osx.jnilib

build/natives/liblwjgl.jnilib

build/natives/libtwitchsdk.dylib

build/natives/openal.dylib

build/tmp

build/tmp/makeStart

build/tmp/makeStart/GradleStart.java

build/tmp/makeStart/GradleStartServer.java

 

Are the classes generated and then cleaned up ?

 

Found some sources in forge-1.7.10-userdev.jar but no EntityTNTPrimed. Also found some sources in .gradle/caches/minecraft as well, but not this one.

 

Eclipse can show the class. Where can I find the associated source so that can attach with it ?

 

[arungupta]

Agreed.

 

In Forge 1.6.4, I was changing the source code, recompiling and showing the effects. But would like to build real plugins in 1.7.10. And so looking at the source code would be handy.

 

For example, I don't know how to get "world" in my plugin so that bigger explosions can be created. Clues ?

[arungupta]

Alright, this was very helpful.

 

So I created my first mod as:

 

@EventHandler

    public void init(EntityJoinWorldEvent event)

    {

    World world = event.world;

    event.world.createExplosion(event.entity,

    event.entity.posX,

    event.entity.posY,

    event.entity.posZ,

    40,

    true);

    }

 

I clicked on the "Run" button to run the client profile. But still not seeing the bigger TNT explosion size.

 

[arungupta]

So I updated the method to:

 

    @EventHandler

    public void init(EntityJoinWorldEvent event)

    {

    if (!(event.entity instanceof EntityTNTPrimed))

    return;

    event.setCanceled(true);

   

    event.world.createExplosion(event.entity,

    event.entity.posX,

    event.entity.posY,

    event.entity.posZ,

    40,

    true);

    }

 

But still not seeing bigger explosions, any suggestions ?

[EmperorZelos]

don't make the explosion too big, they look utter shtie when too big

[arungupta]

This will be shown in Minecraft workshops and boys love bigger explosions.

 

The question being I'm not seeing the bigger size though. What needs to be different in the code to make the explosion bigger ?

[EmperorZelos]

world.createExplosion(splosion, (double)x, (double)y, (double)z, 15.0F, true);

the 15.0F is what determined the explosion size, when you reach 50 and higher the explosion lags and starts looking utter shite

[arungupta]

How should the code be modified ? The first parameter is "event.entity" instead of "splosion", right ?

[EmperorZelos]

EntityItem splosion = new EntityItem(world,(double)((float)x),(double)((float)y),(double)((float)z), new ItemStack(Blocks.dirt,1,0));
	world.spawnEntityInWorld(splosion);
	world.createExplosion(splosion, (double)x, (double)y, (double)z, 15.0F, true);
	world.removeEntity(splosion);

This is the code I use for random explosions I want, create an entity of some blkock (here dirt) in the world at x,y,z. then creates the entity, explodes and then removes it quickly.

[arungupta]

The following code still does not work:

 

@EventHandler

    public void init(EntityJoinWorldEvent event)

    {

    if (!(event.entity instanceof EntityTNTPrimed))

    return;

   

    EntityItem splosion = new EntityItem(event.world,

    event.entity.posX,

event.entity.posY,

event.entity.posZ,

new ItemStack(Blocks.dirt,1,0));

event.world.spawnEntityInWorld(splosion);

event.world.createExplosion(splosion,

    event.entity.posX,

event.entity.posY,

event.entity.posZ,

25.0F, true);

event.world.removeEntity(splosion);

    }

 

Thoughts ?

[arungupta]

Didn't work. Here is my complete class:

 

package org.devoxx4kids.forge.plugins.biggertnt;

 

import net.minecraft.entity.item.EntityItem;

import net.minecraft.entity.item.EntityTNTPrimed;

import net.minecraft.init.Blocks;

import net.minecraft.item.ItemStack;

import net.minecraft.world.World;

import net.minecraftforge.event.entity.EntityJoinWorldEvent;

import cpw.mods.fml.common.Mod;

import cpw.mods.fml.common.Mod.EventHandler;

import cpw.mods.fml.common.event.FMLInitializationEvent;

import cpw.mods.fml.common.eventhandler.SubscribeEvent;

 

@Mod(name = BiggerTNTExplosion.NAME, modid = BiggerTNTExplosion.MODID, version = BiggerTNTExplosion.VERSION)

public class BiggerTNTExplosion

{

    public static final String MODID = "examplemod";

    public static final String VERSION = "1.0";

    public static final String NAME = "1.7.10";

   

    @EventHandler

    public void init(FMLInitializationEvent event)

    {

//    world.createExplosion(exploderEntity, x, y, z, radius, spawnParticles);

// some example code

    System.out.println(NAME + " mod loaded");

//        System.out.println("DIRT BLOCK >> "+Blocks.dirt.getUnlocalizedName());

    }

   

//    @EventHandler

//    public void init(EntityJoinWorldEvent event)

//    {

//    if (!(event.entity instanceof EntityTNTPrimed))

//    return;

//   

//    event.setCanceled(true);

//    event.world.createExplosion(event.entity,

//    event.entity.posX,

//    event.entity.posY,

//    event.entity.posZ,

//    15.0F,

//    true);

//    }

 

   

    @SubscribeEvent

    public void init(EntityJoinWorldEvent event)

    {

    if (!(event.entity instanceof EntityTNTPrimed))

    return;

   

    EntityItem splosion = new EntityItem(event.world,

    event.entity.posX,

event.entity.posY,

event.entity.posZ,

new ItemStack(Blocks.dirt,1,0));

event.world.spawnEntityInWorld(splosion);

event.world.createExplosion(splosion,

    event.entity.posX,

event.entity.posY,

event.entity.posZ,

25.0F, true);

event.world.removeEntity(splosion);

    }

   

}

 

Suggestions ?

[arungupta]

Oh yeah, that was it, thanks a lot!

 

What's the purpose of spawning a new entity instead of using event.entity ? The following code, as opposed to  the one given above, worked as well:

 

    @SubscribeEvent

    public void init(EntityJoinWorldEvent event)

    {

    if (!(event.entity instanceof EntityTNTPrimed))

    return;

   

        event.world.createExplosion(event.entity,

    event.entity.posX,

event.entity.posY,

event.entity.posZ,

25.0F, true);

    }

 

[arungupta]

got it, thanks!

[arungupta]

By default, TNT explodes 4 seconds after being lit. In this case, it blows up right away. How do I implement the "wait" behavior with the bigger explosion mod ?

[arungupta]

Didn't mean to hijack the thread, was just asking a follow up question

 

Anyway, will start a new thread for a specific question.
