Reading the pstate attribute
The pstate attribute is actually a “bit field”, storing several different state flags in a single value. Houdini calculates the value of pstate by adding up the following values for each flag that is on:
| Flag | Value |
|---|---|
| Dead | 1 |
| Stopped | 2 |
| Stuck | 4 |
| Just hit | 8 |
For example:
| Particle | pstate value |
|---|---|
| Active | 0 |
| Stopped | 2 |
| Stopped and dead | 3 (2 + 1) |
| Stuck and just hit | 12 (4 + 8) |
