If the subject is performing the action, then the sentence is in an active voice. However, if the subject is simply receiving the action, then the sentence is in a passive voice. A helpful tip is to add "by zombies" after the verb. It helps a ton. If you can insert "by zombies" after the verb then it is passive.
