HARFANG Physics QA tests

A series of test, implemented in Lua, for QA'ing the integration of Bullet Physics into HARFANG. Each .lua unit as a specific purpose. The list below is meant to set an overall roadmap of the topics to be tested:

Collision shapes

• check dimensions, matching ScenePhysicDebug with specified dimensions
  • quick visual check with HG Studio is welcome
• check transformations
• correct handling of multi shape (eg. chair with multiple box coll)

Body types (cube, sphere, cylinder...)

• static

  • no reaction to forces (gravity, force, impulse, collisions)
  • cannot be moved

• kinematic

  • no reaction to forces (gravity, force, impulse, collisions)

  • movable in code

    • get() new coordinates?

  • kinematic parenting must work

    • via instantiation
    • via animation

• dynamic

  • reaction to forces (gravity, force, impulse, torque, collisions)

• interaction between types

  • static/kinematic interaction
    • collision event should be raised! (e.g. implement a character controller by hand)
  • kinematic/dynamic interaction (moving platform with a cube/sphere/cone on it)
    • check collision event
  • dynamic/dynamic interaction

Raycast

• Press the R key to casts 4 raycasts offseted on X and Y view space and displays in 3d the intersection points (white ray to the intersection point or red if no intersection)

Collision event

• display the number of collisions in the frame
• provide visual output (ScenePhysicDebug probably)

Restitution

• ground plane with 10 cubes bouncing from a pre-defined height (0, 0.1, 0.2, 0.3, etc...)

Friction

• ground plane with 10 sliding cubes (0, 0.1, 0.2, 0.3, etc.)

Addition/removal of physical elements

• TODO
