Controller floats away playing Unity game but not on SteamVR Home.

[algoer]

Hello, I am a beginner so this is a little frustrating.

My Vive controller works fine when I am on the Home SteamVR environment that automatically starts up. However, I have a created a Unity game and my controllers are veryy glitchy. 1, one of the controllers appears at the very bottom of the camera on start of the game, then it goes back to the regular positions. Both of the controllers are doing this thing where they appear then fly away, appear then fly away. The game is unplayable. 

Any help would be greatly appreciated!
