Unity Tutorial 03

This week on Unity I followed the tutorials to make a game where there are 3 animals running towards the player from random positions and you can shoot pizza at them. I really enjoyed this week tutorials and it helped me understand Unity even more. I was wondering before this tutorial how to make stuff spawn and disappear at a certain point so they are not just running of and not disappearing. This tutorial thought me how to get rid of the animals when they reach a certain point and also how to get rid of the pizza when it reaches a certain point. I found these tutorials really interesting and I feel as if the tutorials have helped me understand Unity a lot better. One thing I would like to know is how to spawn the animals automatically, for example maybe every 5 seconds because at the moment they only spawn when I press the S key. I have some ideas in my head as to how some of the stuff I learned could be applied to my own game.

Anyway, I found that tutorial really interesting and fun, I'm excited to see what the next set of tutorials are and to learn more stuff to apply to my own game.
