Physics Actor¶

Physics actor is the most basic actor type. It is used when we want to only simulate the physics of an object without rendering it.

In order to create a Physics Actor you need to:

1. Create a Simulation Mesh from the tetrahedral mesh.

   You can create the simulation mesh from the source tetrahedral mesh with the tool described here. In this case the simulation mesh can of any configuration.

2. Create a SoftbodyActor and assign the Simulation Mesh.

   Create an empty GameObject and add a SoftbodyActor component to it by clicking Add Component > MAGES > Mesh Deformations > Actors > Physics Actor in the inspector

   

   Assign the Simulation Mesh and a Physics World to the SoftbodyActor component

   

3. Press Edit Particles in the inspector to edit particles in the Scene view.

   Instructions

   • Left click: make particles kinematic.

   • Shift + left click: make particles non-kinematic.

   • Alt + drag: marquee-select particles and make them kinematic.

   • Shift + Alt + drag: marquee-select particles and make them non-kinematic.

   Particle Ledger

   • Red: kinematic.

   • Green: non-kinematic.

   • Blue: selected.

   Configuration Settings

   • Particle scale: How big particles are, helping with the visualization.

   • Particle count: How many particles show. Restricting the number of particles shown can help with performance when editing large meshes.

   

   Marquee Selection can help you select multiple particles at once. You can hold the Alt key and drag to marquee-select particles and make them kinematic, or hold Shift + Alt and drag to marquee-select particles and make them non-kinematic.
