Custom Spots Filter Generator Module

[mercior]

Hey Aka, Thanks for your reply. I ended up fixing it myself - it was my bad use of the SubArray<> class where I was using spots.Spots.Array.Count instead of spots.Spots.Count - it was accessing the unused, but allocated elements of the array

---

For anyone who may want it in the future, here is the fixed code. I note that I had to change the original volume spots generation to use full rotation so the spots are generated at the correct angle for this filter to check their angle, then this module compares the angle to the horizon, filters spots based on that, and then sets the spots to default rotation so they always face the ground.

Code:

using UnityEngine;
using System.Collections;
using FluffyUnderware.DevTools;
using System.Collections.Generic;

namespace FluffyUnderware.Curvy.Generator.Modules
{
    [ModuleInfo("Custom/Spot Angle Filter",ModuleName="Spot Angle Filter", Description="Filter spots based on their rotation")]
    public class SpotAngleFilter : CGModule
    {
       
        [HideInInspector]
        [InputSlotInfo(typeof(CGSpots), Name = "Spots", DisplayName = "Spots")]
        public CGModuleInputSlot InData = new CGModuleInputSlot();

        [HideInInspector]
        [OutputSlotInfo(typeof(CGSpots), Name = "Spots", DisplayName = "Spots")]
        public CGModuleOutputSlot OutData = new CGModuleOutputSlot();
