Click in the direction you would like to walk. For example, to enter through the front door, place your mouse pointer at the center of the doorway and click.
Or, you may also place your mouse pointer on the floor or ground and you will see directional arrows that can be clicked.
To pan from left to right or look up or down, click-hold your mouse and pull in the direction you would like to look.
If you are using a mobile device or tablet the instructions are the same but you must click on the floor arrows to travel through the gym.
