The **Age Over Lifetime** Operator returns the age of a particle relative to its lifetime, as a value between 0.0 and 1.0.
|
|
|
|
```
|
|
t = age / lifetime
|
|
```
|
|
|

## Details
|
|
|
|
If the system you use this Operator in does not include either age or lifetime, Unity uses the default attribute values instead.
|
|
|
|
- Age defaults to **0**.
|
|
- Lifetime defaults to **1**.
