Fire Magic Book

Hello, I'm making this mod and I want to give this item special powers to spawn fire at random blocks in a 3x3 radius at the coordinates the player is looking at, here is the code:

public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer entityplayer)

{

//itemstack.damageItem(10, entityplayer);

world.playSoundAtEntity(entityplayer, "fire.ignite", 0.7f, 0.8f);

if (!world.isRemote)

{

Vec3 look = entityplayer.getLookVec();

Blocks.fire firemass7 = new Blocks.fire(world, entityplayer, 1, 1, 1);

firemass7.setPosition(

entityplayer.posX + look.xCoord,

entityplayer.posY + look.yCoord,

entityplayer.posZ + look.zCoord);

    world.setBlock(firemass7);

}

return itemstack;

}

I am using forge 1.7.10, as I want to make the mod in this version. The problem is that the Blocks.fire can't be resolved to a field, could anyone please let me know how to fix that, or any other mistakes you see in this coding? Thank you.
