Unity Waits, Delays, and Timers

This Unity Tutorial will show you 3 different methods to make a timer and be able to delay or wait between functions in your Unity3D scripts

Time Breakdown

• 0:30 - Setting up our variable
• 1:50 - Invoke method
• 4:40 - IEnumerator method
• 8:20 - Update method with Time.deltaTime
• 11:40 - Outro, thanks for watching :D

Check out the videos above to hear the explanation and see the code in action
