Rotating props without PropRotatingParams mod (based on a script by Ronyx69) - Multiple rotating parts

prop-rotating-multi.cs

// Warning: Do not save vehicles after running this script without a game restart!

// Prop Rotating Script for multiple rotating parts.
// Control rotation axis, pivot and speed.

// Run in asset editor and see effects in real time.

// The LODs are not rotating, they are like regular props.

// Vertex color blue channel for rotating parts must be 0.
// Non-rotating parts remain vertex color white.
// Google how to do vertex color painting in your 3d software of choice!
// You can have 4 different rotating parts, (0 to 3)
// each needs a different value for vertex color green channel.

// If you are making a clock, set clock value to 1.
// speed for the 12 hour arm is 2,
// for the minute arm it's 24,
// for the second arm it's 1440.

// Part 0 (vertex color green channel = 0)

var pivot0 = new Vector3(0.0f, 0.0f, 0.0f); // Pivot point - center of rotation.
var speed0 = 1.0f; // Rotations per minute / per day for clocks (negative to reverse direction)
var clock0 = 0.0f; // Set to 1 to tie rotation to game clock.

// Part 1 (vertex color green channel = 64)
var axis1 = new Vector3(0.0f, 1.0f, 0.0f); // Set to 1 to choose rotation axis.
var pivot1 = new Vector3(0.0f, 0.0f, 0.0f); // Pivot point - center of rotation.
var speed1 = 1.0f; // Rotations per minute / per day for clocks (negative to reverse direction)
var clock1 = 0.0f; // Set to 1 to tie rotation to game clock.

// Part 2 (vertex color green channel = 128)
var axis2 = new Vector3(0.0f, 1.0f, 0.0f); // Set to 1 to choose rotation axis.
var pivot2 = new Vector3(0.0f, 0.0f, 0.0f); // Pivot point - center of rotation.
var speed2 = 1.0f; // Rotations per minute / per day for clocks (negative to reverse direction)
var clock2 = 0.0f; // Set to 1 to tie rotation to game clock.

// Part 3 (vertex color green channel = 192)
var axis3 = new Vector3(0.0f, 1.0f, 0.0f); // Set to 1 to choose rotation axis.
var pivot3 = new Vector3(0.0f, 0.0f, 0.0f); // Pivot point - center of rotation.
