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.

Ports

Name	Direction	Type	Description
Seed	Input	Vector 2	Seed value used for generation
Min	Input	Float	Minimum value
Max	Input	Float	Maximum value
Out	Output	Float	Output value

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);
}
