How can I play music when a player is wearing my block that is wearable as a helmet?

i just can`t find a solution for it

 

What do i want to do with it?

watch this:https://www.youtube.com/watch?v=fmrA-gxJxgQ

i want to make the floating colored cubes around miku,and make it play that music/other music

 

also,has anyone figured out how to animate json models through java code?

the item have to read an audio file .ogg

Thx,but now i can`t figure out how to make my block go  in the head slot

code:

package zhang.DBound.blocks;

import net.minecraft.block.Block;
import net.minecraft.block.BlockPumpkin;
import net.minecraft.block.material.Material;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;

public class miku_aura extends Block {

public miku_aura(Material material) {
	super(material);
        this.setCreativeTab(CreativeTabs.tabCombat);
        this.setUnlocalizedName("miku_aura");
        this.setHardness(0.5F);
        this.setResistance(6.0F);
        this.setStepSound(soundTypeMetal);
  }
 public boolean isItemValid(ItemStack par1ItemStack)
 {
	 if (armorType == 0) //here lays a error
       {
            return Item == DBoundBlocks.miku_aura; //here lays a error
       }

       return false;
     }


}

you can use json models,and use a generator to animate them

it seems like u never made a custom resource pack....

No, I have  indeed not. But I am pretty damn sure that the json format does not support animation natively.

There is texture animation, but that's it.

No. There's native json animation.

Here's vanilla command block thing where it's used:

The heck? Never seen that before. And I fail to find anything about it on the minecraft wiki...

I had the same reaction.

Forge recently  added a model animation system.

 

I have no idea what the video is using and annoyingly he doesn't seem to explain it or provide a map/resource pack download.

Well, this is interesting: http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-tools/2478389-block-models-animated-minecraft-model-generator

Create new item class that extends ItemBlock. When registering you block, use method with

Class<? extends ItemBlock>

, and pass

YourItemBlock.class

.

I your item block class, you can override

canBePlacedInArmorSlot

or something like that, use your IDE to find method to override, but there's one.
