Overrides:

postinteract

public void postinteract(java.util.ArrayList<IDynamics> agents)

Description copied from interface: IDynamics

executed after interact(ArrayList). behavior can be changed by IConfig.enablePostinteract and IConfig.loopPostinteract. If IConfig.loopPostinteract is false, preupdate is executed before post interact (updated 2012/08/26).

Specified by:

postinteract in interface IDynamics

Overrides:

postinteract in class IWall

bounce

public void bounce(IParticleI particle,
          java.util.ArrayList<IDynamics> agents)

Calculate bouncing behavior of particle. With IConfig.checkAdjacentWalls=true, it checks other walls if the particle could collide into others within the same time frame and find which one to collide first. When bouncing, a particle doesn't necesarily stop at the intersection point on the wall because within one time frame, the particle moves distance of particle.vel() * IConfig.updateRate and IWall move the corresponding distance after bouncing. So if a particle is fast, user might not see the moment the particle is touching the wall. Instead, if the particle inherets ITrajectoryI, IWall inserts an intersection point into the trajectory curve.

Overrides:

bounce in class IWall
