Attempting to build a simple item that can be crafted (I have the crafting path set up and all) and used as a permanent egg essentially. I'm hoping for it to be able to spawn any random monster on whatever ground is right clicked with it. My current code is basically this

 

public boolean onItemUse(ItemStack item, EntityPlayer player, World world, int x, int y, int z, int side, float xOffset, float yOffset, float zOffSet)

{

 

if (world.getBlockId(x, y + 1, z) == 0 && (world.getBlockId(x, y, z) == Block.grass.blockID || world.getBlockId(x, y, z) == Block.stone.blockID || world.getBlockId(x, y, z) == Block.dirt.blockID || world.getBlockId(x, y, z) == Block.sand.blockID))

{

 

                                int x = math.random();

                                if(x<0.05) {

                                EntitySkeleton ent = new EntitySkeleton(world);

ent.setLocationAndAngles(x, y + 1, z, MathHelper.wrapAngleTo180_float(world.rand.nextFloat() * 360.0F), 0.0F);

ent.initCreature();

world.spawnEntityInWorld(ent);

                                }

                                else if(x<0.1) {

                                  ...and so on

}

return true;

}

 

I keep on coming up with these errors:

and my full code is

 

 

package com.derp.fail;

import net.minecraft.entity.monster.EntitySkeleton;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.init.Blocks;

import net.minecraft.item.Item;

import net.minecraft.item.ItemStack;

import net.minecraft.util.MathHelper;

import net.minecraft.world.World;

 

public class Book extends Item {

public Book() {

 

}

 

public boolean onItemUse(ItemStack item, EntityPlayer player, World world, int x, int y, int z, int side, float xOffset, float yOffset, float zOffSet)

{

 

if (world.getBlockMetadata(x, y + 1, z) == 0 && (world.getBlockMetadata(x, y, z) == Blocks.grass.blockID || world.getBlockMetadata(x, y, z) == Blocks.stone.blockID || world.getBlockMetadata(x, y, z) == Blocks.dirt.getBlockMetadata(x, y, z) || world.getBlockMetadata(x, y, z) == Blocks.sand.blockID))

{

EntitySkeleton ent = new EntitySkeleton(world);

ent.setLocationAndAngles(x, y + 1, z, MathHelper.wrapAngleTo180_float(world.rand.nextFloat() * 360.0F), 0.0F);

ent.initCreature();

world.spawnEntityInWorld(ent);

}

return true;

}

 

}

 

 

 

Thanks in advance for any help/suggestion that you could provide. I'd like to finish this ASAP, so a quick response would be greatly appreciated.

There is no

Block#blockID

field in 1.7.10 since IDs are automatically managed. Use

World#getBlock

and compare the

Block

instances directly with

==

.

 

There is no

initCreature

method in any subclass of

Entity

. Were you looking for

EntityLiving#onSpawnWithEgg

?

 

Always annotate override methods with

@Override

so you get a compilation error if the method doesn't actually override a super method.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Are you using Eclipse as your IDE? If so, then it should be helping you to see syntax and semantic errors. Between Eclipse's bright red X's, its power features, and your knowledge of Java, you should be able to get pretty close to compiled before coming here. If not, then tell us what's still marked red in Eclipse so we can point you toward the Forge class / method that you need to pick up.

 

If you're using Eclipse correctly (and have an uncorrupted decompiled workspace), then gradle will never give you compilation errors.

 

PS: If you're using Eclipse for Java but it's unfamiliar to you, then take time out to go walk through an Eclipse tutorial.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.
