Using the Player to view a model is straightforward. A well-designed and documented Player file should be largely self-explanatory. This is particularly the case for Player files with Dashboards Specialized user interfaces that can be built into a Player file. Dashboards look like "control panels", with buttons, sliders and display panels, and provide a mechanism by which inputs to a model can be modified within the Player.. If you want to view and navigate the underlying model (which is all that you can do if the Player file does not have a Dashboard), however, you will need to know something about the basics of the GoldSim simulation environment.
