first person controller bounces down to the floor

When game play starts the controller bounces down to the floor. I got it to stop falling through the floor using rigid body, but it still bounces down when game play starts. Any suggestions? Thanks

If you do not want an object to be affected by gravity, simply uncheck the Use Gravity box in the Rigidbody window in the inspector.

Thanks andzq. Already unchecked Use Gravity. Also used Rigid Body on the floor. That kept if from drifting into infinity. But the controller is still starting up higher and bouncing down onto the floor when the game play starts…
