  1 +# Bullet physics example
  2 +
  3 +This is an example showing how to use the Bullet physics library to create and control
  4 +physics objects in DALi.
  5 +
  6 +It creates a pyramid of bricks and a ball falling onto a large block.
  7 +
  8 +The user can select and drag any of the actors with the mouse.
  9 +The user can zoom in and out using the mouse wheel.
  10 +
  11 +"wasd" keys move the last touched actor up/down/left/right.
  12 +"qe" keys rotate the last touched actor in Z axis
  13 +"zx" keys rotate the last touched actor in Y axis
  14 +"cv" keys rotate the last touched actor in X axis
  15 +"p" key resets the position/forces on the last touched actor to the origin
  16 +
  17 +"m" key toggles the debug rendering
  18 +Space key toggles the integration state.
