Stop rotating when the camera hits the floor

Trying to limit the Miny when i rotate the camera on the y when it hits the floor.

Currently the camera does stop rotating when he hits the floor but the camera shakes like its fighting with some vector. If anybody can help? or need more info.

Basically this is for a third person camera script which follows the player and it will rotate on x and y around the player, but it goes though the floor.
