28. How to make a 2D Platformer - UPGRADE 2.0 - Unity Tutorial

jvernon

On this video we are using for class. When my student enters in the correct scripting for the Gamemaster script with no errors, when he hits U to toggle the Upgrade Menu nothing happens. He has his menu setup correct and his script is correct...no errors, just not bringing up the Upgrade menu when he hits U. Happens on play in unity and the build.

Any suggestions? Thanks.
