Random Get Float Around Center
Gets a random float value within a range defined by a center and a magnitude:
[Center - Magnitude, Center + Magnitude].
Optionally applies a falloff curve to bias how values are distributed around the center - for example, to make results cluster near the center or more likely at the extremes.
Use it for effects like natural variation, noise, random offsets, or imprecise targeting.
Parameters
| Parameter | Description |
|---|---|
| Center | The midpoint of the random range. |
| Magnitude | The maximum deviation from the center. The result will be between Center - Magnitude and Center + Magnitude. |
| Falloff | An AnimationCurve defining the probability falloff by distance from the center.Leave unset for a uniform distribution. |
| Store Result | Float variable to store the random value. |

Tips
- Repeatability: Combine with Random Init State to reproduce the same sequence of results.
- Uniform vs. curved: Leave Falloff unset for even probability; use a curve to bias results toward or away from the center.
- Use global AnimationCurve variables for commonly re-used curves, or curves that you want to tweak in one place.
Common Pitfalls
- Negative magnitude: Automatically clamped to zero.
- Unset falloff: Uses a uniform distribution, not a bell curve.
- Extreme curve values: Overshooting above 1 on the Y-axis may flatten or exaggerate results unpredictably.
