[answered] Help with crashing

I made a block using your tutorial and it is supposed to heal you. but when i touch it, it changes minecraft to a saving chunks screen and then minecraft crashes. why is this?

Admin Edit: Please use proper topic format. I'll fix for you.

Please post code and error. In order to get the error run minecraft in error mode.

it doesnt give me an error when i start it would error mode still work?

Code:

package net.minecraft.src;
 
import java.util.Random;
 
public class Blockcocopad extends Block
{
 
    public Blockcocopad(int i, int j)
    {
        super(i, j, Material.iron);           
    }
    public int idDropped(int i, Random random)
    {
      return mod_Coco.cocopad.blockID;
    }
    public int quantityDropped(Random random)
    {
            return 0;
    }
    public AxisAlignedBB getCollisionBoundingBoxFromPool(World world, int i, int j, int k)
    {
        float f = 0.0625F;
        return AxisAlignedBB.getBoundingBoxFromPool((float)i + f, j, (float)k + f, (float)(i + 1) - f, (float)(j + 1) - f, (float)(k + 1) - f);
    }
    public AxisAlignedBB getSelectedBoundingBoxFromPool(World world, int i, int j, int k)
    {
        float f = 0.0625F;
        return AxisAlignedBB.getBoundingBoxFromPool((float)i + f, j, (float)k + f, (float)(i + 1) - f, j + 1, (float)(k + 1) - f);
    }
    public void onEntityCollidedWithBlock(World world, int i, int j, int k, Entity entity)
    {
        entity.attackEntityFrom(null, -1);
    }
}

You`re the guy working on Cocosmackdowns mod .

that would be a yes... These are the tuts i have been using the whole time. Thanks for recognizing me

Edit: ignore this

Blockcocopad.class =

Code:

package net.minecraft.src;

import java.util.Random;

public class Blockcocopad extends Block
{

    public Blockcocopad (int i, int j)
    {
        super(i, j, Material.ground);     
    }
    public int idDropped(int i, Random random)
    {
      return mod_cocopad.Namehere.blockID;
    }
    public void onEntityWalking(World world, int x, int y, int z, Entity entity)    {
       entity.motionY += 5.0;   
       }
    public int quantityDropped(Random random)
    {
            return 3;
    }
}
 

mod_cocopad.class

Code:

package net.minecraft.src;

public class mod_cocopad extends BaseMod
{
  public static Block Namehere = new Blockcocopad(190, 0).setHardness(1.0F).setResistance(6000.0F).setLightValue(1.0F).setBlockName("Namehere");
 
  public String Version()
  {
      return "1.8.1";
  }
 
  public mod_cocopad()
  {
      ModLoader.RegisterBlock(Namehere);
      Namehere.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/cocopad.png");
      ModLoader.AddName(Namehere, "Namehere");
      ModLoader.AddRecipe(new ItemStack(Namehere, 1), new Object[] {
      "###", "###", "###", Character.valueOf('#'), Block.dirt
      });
  }
}
 

Change anything from the how far you jump to recipe to how many blocks it drops. I don`t know if its any diff from yours but i tested it and it works.
Plus if it works can i get credit for fixing the bug :3.

How would i set it to heal though. i am trying to make it heal not bouncy.

fail . I thought it was the pad you jumped on cause coco said you get saving chunks if you step on it.

it is... its gonna allow you to bounce... I might just ditch the healing idea.

I`ll try and get some fixed code.

Code:

    public void onEntityCollidedWithBlock(World world, int i, int j, int k, Entity entity)
    {
     entity.attackEntityFrom(DamageSource.func_35524_a(entity, entity), -4);
    }
 

Use that code to heal i`ve tested it. the -4 is how many half hearts it heals.
Note that it does make the noise like you get hurt but it heals you. You can change this by changing the function from DamageSource.
This goes in Blocknamehere
If you use this in mod can i get credit for fixing it?

ya sure

You still keeping the healing thing in the mod?
