| Position | P | The Point3d Position of the Agent. | Point |
| Velocity | V | The direction and magnitude of the Quelea's movement. | Vector |
| Acceleration | A | The vector of the Quelea's acceleration. | Vector |
| Lifespan | L | Number of timesteps that the Quelea will be alive for. If negative, lifespan will be infinite. | Integer |
| Surface Position | SP | For particles bound to Surface and Polysurface Environments, the position of the Agent mapped to a 2D plane representing the bounds of the surface. | Point |
| Surface Velocity | SV | For particles bound to Surface and Polysurface Environments, the velocity of the Agent mapped to a 2D plane representing the bounds of the surface. | Vector |
| Surface Acceleration | SA | For particles bound to Surface and Polysurface Environments, the acceleration of the Agent mapped to a 2D plane representing the bounds of the surface. | Vector |
