Please make sure the agent type you are going to use has a ragdoll file as described here.



Create a new scene and follow these steps:

  • Create an agent group and set its display type to skin.
  • Add a grid layout module.
  • Create a plane, scale it by 500 on all axis and add it as an height field with the height field manager .
  • Duplicate the plane and set the duplicated plane Y value to -1
  • With the duplicated plane selected, click on the shelf button for creating a rigid body  (AtomsPhysx shelf)
  • Set the rigid body mesh type to plane
  • Select the agent group again.
  • Add a state machine module.
  • Set the height field of the state machine to the height field you just created.
  • Select the tcAtomsSolver (you will find a tab in the attribute editor when having any agent group selected), enable Physx , set the scale to 100 and the sub samples to 15.
  • Add a ragdoll module to the agent group.
  • Set the mode of the ragdoll module to "3 - ragdoll" and press play.
  • You will see your agent falling on the floor.


Let's keep working on this scene:

  • Set the State Machine module state to 1.
  • Change the ragdoll module mode value to "2 - kinematic"
  • Set a key frame on the mode field at frame 1, by right clicking on the drop down menu and clicking "set key".
  • Set another frame at frame 10, then move to frame 11 and set a keyframe with value "3-ragdoll".
  • Press play.
  • You will see the agent walking for 10 frames and then falling down.



  • Rewind the animation.
  • Right click again on the mode field of the ragdoll module and click on "Break connections" (the mode should be set to 2-kinematic)
  • Create a plane, scale it by 200 and move it <150, 70, 0>.
  • Select the atoms group and add an area trigger module.
  • Set the plane as mesh for the area trigger module, then set the metadata name to "dynamicMode" and the field "Int Value" to 3.
  • Select the ragdoll module and turn on the "useDynamicModeMetadata" option.
  • Press play.
  • You will see the agent walking and then falling down as soon as it enters the areaTrigger plane.


Please feel free to expirement a bit more, by playing with the ragdoll module options and by adding more agents to your simulation.
