Soft Body Physics

    Your setup will involve making sure you have sufficient geometry in the soft body's mesh tosupport the deformation, as well as tweaking the options.

    • Actor
    • Enables detection by Near and Radar Sensors.
    • Ghost
    • Disables collisions completely, similar to No Collision.
    • Invisible
    • Does not display, the same as setting the object to unrendered(such as unchecking the camera icon in the Outliner).
    • Mass
    • Affects the reaction due to collision between objects —more massive objects have more inertia. Will also affect material force fields.Will also change behaviors if you are using the suspension and steering portions of Bullet physics.
    • Shape Match
    • Threshold

    • .

      • A threshold of 1.0 makes it behave like Shape Match on with a Linear Stiffness of 1.0.
      • A threshold of 0.0 makes it behave like Shape Match off with a Linear Stiffness of 0.0.
    • Welding
    • TODO.
    • Position Iteration
    • Increase the accuracy at a linearly-increasing expense of time.The effect is visible especially with soft bodies that fall on sharp corners,though this can slow down even very simple scenes.
    • Linear Stiffness
    • Linear stiffness of the soft body links.This is most evident when you have Shape Match off, but it is also evident with it on.
    • Friction
    • Dynamic friction coefficient.
    • Small value makes the algorithm unstable.
    • Bending Constraint
    • Enable Bending Constraints.
    • Cluster Collision
      • Rigid to Soft Body
      • Enable cluster collisions between rigid and soft bodies.
      • Soft to Soft Body
      • Enable cluster collisions among soft bodies.
      • Iterations
      • Number of cluster iterations.
    • A very important configurable in the case of soft body interactions isWorld Properties‣ Physics ‣ Physics Steps ‣ Substeps.

    Note

    Soft bodies do not work with the Collision, Touch, Near, and Radar logic brick sensors.

    A common practice within the non-BGE Cloth simulator is to employ to animate the cloth.These do not work in the BGE, so you will have to figure out a way to use Python(or perhaps plain Logic Bricks) to apply forces to the soft body objects.
