The Browser tab is where you can add and load assets to the Player and play them.

The buttons on the screen perform the following actions:

Add Assets...: Adds assets one at a time. In the resulting dialog box, navigate to the desired file to load it into the Player's browser. Files can also be added via drag and drop from Windows File Explorer.
Remove: Removes the selected asset from the list.
Remove All: Removes all assets from the list.
Load: Loads a selected asset from the list. You must load an asset before you can play it.
Unload: Unloads a selected asset. You cannot play this asset again until you reload it.
Unload All: Unloads all loaded assets.

Simulation Controls

The Player's application mode is set to Editing upon loading. While in Editing mode, you are able to load assets. Once you load an asset in the browser (using the Load button), use the simulation controls to interact with it. The controls behave in the following ways:

Play: Launches/resumes the simulation. The application mode is set to Simulating and is running. While playing, the Play button turns into a Pause button.
Pause: Pauses the simulation. The application mode stays in Simulating but is paused. The button is visible only when simulation is running.
Step: Launches/resumes the simulation for one frame then pauses. The application mode is set to Simulating and is paused between frames.
Stop: Stops the loaded simulation that is currently playing. The frame and simulation time are reset to zero. The asset is restored to its initial state and the application mode is set to Editing.

Keyboard Help

When you are running a simulation in the Main Window, you have access to many features with keyboard shortcuts. For example, if you press the F1 key, the following help shortcuts appears overlaid on the simulation:

F2: Cycle polygon fill mode
F3: Toggles the Graphics Information Display
Alt-Enter: Toggle full-screen
Alt-O: Write passes to file (saved_scene.osg)
Alt-P: Debug next render pass
Shift-Alt-E: Toggle shadows
Shift-Alt-P: Debug previous render pass
Shift-Alt-R: Reload all shaders
Alt-Ctrl-P: Deactivate render pass debugging

Press F1 again and the second page appears:

F7: Toggle pause/run the simulation
F8: Step the simulation once
Shift-C: Toggle contact display
Shift-G: Toggle collision geometry (CG) display
Shift-I: Toggle inertia tensor display
Shift-J: Toggle constraint display
Shift-M: Toggle center of mass (COM) display
Shift-O: Toggle the graphics node origin
Shift-P: Print universe content (universe.txt)
Alt-C: Cycle between contact display types
Alt-G: Toggle attachment point display
Alt-P: Print contact pairs
Alt-X: Halve the length of the lines in the contact display
Alt-Z: Double the length of the lines in the contact display
Shift-Alt-D: Verify dynamics
Shift-Alt-M: Toggle part origin display
Shift-Alt-P: Print contact property pairs

Press F1 again to see the third page:

C: Cycle through all cameras
R: Cycle through all roles
Ctrl-Shift-D: Dump the current application configuration and content

When you press F1 just one more time, the keyboard help disappears.
