I'd already registered it, and had it working. I just needed the item. I did look at the boat code, to no avail. I'm still quite clueless. Here's the code:
public class MobSpawner extends Item {
public MobSpawner(int par1)
{
super(par1);
this.setCreativeTab(MyMod.MyTab);
}
/**
* Called whenever this item is equipped and the right mouse button is pressed. Args: itemStack, world, entityPlayer
*/
public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
{
float f = 1.0F;
float f1 = par3EntityPlayer.prevRotationPitch + (par3EntityPlayer.rotationPitch - par3EntityPlayer.prevRotationPitch) * f;
float f2 = par3EntityPlayer.prevRotationYaw + (par3EntityPlayer.rotationYaw - par3EntityPlayer.prevRotationYaw) * f;
double d0 = par3EntityPlayer.prevPosX + (par3EntityPlayer.posX - par3EntityPlayer.prevPosX) * (double)f;
double d1 = par3EntityPlayer.prevPosY + (par3EntityPlayer.posY - par3EntityPlayer.prevPosY) * (double)f + 1.62D - (double)par3EntityPlayer.yOffset;
double d2 = par3EntityPlayer.prevPosZ + (par3EntityPlayer.posZ - par3EntityPlayer.prevPosZ) * (double)f;
Vec3 vec3 = par2World.getWorldVec3Pool().getVecFromPool(d0, d1, d2);
float f3 = MathHelper.cos(-f2 * 0.017453292F - (float)Math.PI);
float f4 = MathHelper.sin(-f2 * 0.017453292F - (float)Math.PI);
float f5 = -MathHelper.cos(-f1 * 0.017453292F);
float f6 = MathHelper.sin(-f1 * 0.017453292F);

float f8 = f3 * f5;
double d3 = 5.0D;
Vec3 vec31 = vec3.addVector((double)f7 * d3, (double)f6 * d3, (double)f8 * d3);
MovingObjectPosition movingobjectposition = par2World.rayTraceBlocks_do(vec3, vec31, true);
if (movingobjectposition == null)
{
return par1ItemStack;
}
else

{

}
}
}
if (flag)
{
return par1ItemStack;

else
