# Random Range Node
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
Returns a pseudo-random number value based on input **Seed** that is between the minimum and maximum values defined by inputs **Min** and **Max** respectively.
|
||
|
|
|
||
|
|
Whilst the same value in input **Seed** will always result in the same output value, the output value itself will appear random. Input **Seed** is a **Vector 2** value for the convenience of generating a random number based on a UV input, however for most cases a **Float** input will suffice.

## Generated Code Example
|
||
|
|
|
||
|
|
The following example code represents one possible outcome of this node.
|
||
|
|
|
||
|
|
```
|
||
|
|
void Unity_RandomRange_float(float2 Seed, float Min, float Max, out float Out)
|
||
|
|
{
|
||
|
|
float randomno = frac(sin(dot(Seed, float2(12.9898, 78.233)))*43758.5453);
|
||
|
|
Out = lerp(Min, Max, randomno);
|
||
|
|
}
