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);
}
