Random Color

Overview

• Node Name: Random Color
• Category: repeat_instant
• File: extensions/flowgraph/nodes/util/randomColor.lua

Generates a random color each frame. Supports a "cute color" mode that produces only highly saturated, vibrant colors.

Color Generation Modes

Normal mode: Each RGB channel is independently randomized with math.random() (0–1).

Cute color mode: Uses HSV color space for vibrant results:

• Hue: fully random (0–1)
• Saturation: biased high - lerp(1, 0.7, square(math.random())) - mostly near 1.0
• Value: biased high - same formula - mostly near 1.0
• Converts via HSVtoRGB() to produce saturated, bright colors

Alpha: Set to 1 by default, or randomized (0–1) when randomAlpha is true.

How It Works

1. Determines alpha: random if randomAlpha is set, otherwise 1.
2. If cuteColor is enabled:
   • Generates random HSV with high saturation/value bias using square(math.random()) distribution.
   • Converts to RGB via HSVtoRGB().
3. Otherwise, generates three independent random values for R, G, B.
4. Outputs the color as {r, g, b, a}.

Usage Example

-- Apply random colors to spawned vehicles:
-- [Spawn Vehicle] → [Random Color] cuteColor=true
--                     → color → [Set Vehicle Color]

-- Generate random colors with varying transparency:
-- [Random Color] randomAlpha=true → color → [Set Decal Color]

-- Direct Lua equivalent for cute colors:
local r, g, b = HSVtoRGB(math.random(), lerp(1, 0.7, square(math.random())), lerp(1, 0.7, square(math.random())))

Key Dependencies

• HSVtoRGB() - engine function for HSV to RGB conversion
• lerp(), square() - math utility functions
