3D Forces Simulation

• WASD - Horizontal/Forward Movement
• Space - Move up
• LeftShift - Move Down
  
• Hold Right Click - Look Around w/ mouse movement 
• V - View Orthographic 2D view
• E - Select Force (Look at force in order to select)
• Q - Deselet Force

Instructions:

Line up the green dot in the center of your screen  with the force you want  to edit on the freebody in the center of the simulation environment. 

With that done, select it (E), and a menu where you can change the force (N), and time (s) will appear. There is also a button that will let you determine whether or not you want the force to be persistent (ignore the time it is applied for).

After editing your forces, click the "Reset/Apply Changes" button, and unpause to see how your changes affect the freebody!
