Controller gives NullReferenceException and Teleporter is unresponsive when collided

Questions & Answers
1

I’m relatively new to the Unity Engine. I’m making a simple game where after the player collects every object in order to reach another scene. However, the teleporter has no response after the player collects every object and collides with the teleporter.

Does anyone know what might have gone wrong with my code? Any help would be appreciated. Thanks. Compiler Error Observation: Console gives a NullReference error everytime the game is running.

Remove the semicolon from line 48

if (count == 4)
