how to use setVelocity

[proicop]

I'm new at making mods and I need to make player moving (not teleporting) I found something like player.setVelocity() but I didn't find any class for a player or any setVelocity method or anything. Can anybody help me?

Her is how I use in an item. It shoots the player in the direction they are looking:

 

    @Override
    protected void onCtrlRight(World worldIn, EntityPlayer playerIn, ItemStack stack) {
        Vec3d lookVec = playerIn.getLookVec();
        double x = lookVec.xCoord;
        double y = lookVec.yCoord;
        double z = lookVec.zCoord;
        playerIn.setVelocity(x * 10, y, z * 10);
        stack.damageItem(1, playerIn);
    }
