Non-Random Patrol

[emmcd333@gmail.com]

Hey Guy,

The random version is fine poking around, but, I’d like to create a a sequential patrol. I prefer not to edit around original code(too many surprises in the past), so, just a quick tip on your way of modifying the Random Patrol edition to accomplish it.

Thanks

Hello,

Here is a modified version of Patrol.cs script. This will also be included in the next version.
There is now an option to set the patrol either Random or Progressive.
Please open Patrol.cs and replace all the code with the following:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103

using System.Collections.Generic; using NodeCanvas.Framework; using ParadoxNotion.Design; using UnityEngine;   namespace NodeCanvas.Tasks.Actions{   [Category("Movement")] [Description("Move randomly between various game object positions taken from the list provided")] public class Patrol : ActionTask<NavMeshAgent> {   public enum PatrolMode{ Progressive, Random }   [RequiredField] public BBParameter<List<GameObject>> targetList; public BBParameter<PatrolMode> patrolMode = PatrolMode.Random; public BBParameter<float> speed = 3; public float keepDistance = 0.1f;   private int index = -1; private Vector3? lastRequest;   protected override string info{ get {return string.Format("{0} Patrol {1}", patrolMode, targetList);} }   protected override void OnExecute(){   if (patrolMode.value == PatrolMode.Random){ var newIndex = Random.Range(0, targetList.value.Count); while(newIndex == index){ newIndex = Random.Range(0, targetList.value.Count); } index = newIndex; } else if (patrolMode.value == PatrolMode.Progressive) { index = (int)Mathf.Repeat(index + 1, targetList.value.Count); }   var targetGo = targetList.value[index]; if (targetGo == null){ Debug.LogWarning("List's game object is null on MoveToFromList Action"); EndAction(false); return; }   var targetPos = targetGo.transform.position;   agent.speed = speed.value; if ( (agent.transform.position - targetPos).magnitude < agent.stoppingDistance + keepDistance){ EndAction(true); return; }   Go(); }   protected override void OnUpdate(){ Go(); }   void Go(){   var targetPos = targetList.value[index].transform.position; if (lastRequest != targetPos){ if ( !agent.SetDestination( targetPos) ){ EndAction(false); return; } }   lastRequest = targetPos;   if (!agent.pathPending && agent.remainingDistance <= agent.stoppingDistance + keepDistance){ EndAction(true); } }   protected override void OnStop(){   lastRequest = null; if (agent.gameObject.activeSelf){ agent.ResetPath(); } }   protected override void OnPause(){ OnStop(); }   public override void OnDrawGizmosSelected(){ if (agent && targetList.value != null){ foreach (var go in targetList.value){ if (go) Gizmos.DrawSphere(go.transform.position, 0.1f); } } } } }

Let me know if this works for you.
Thanks

Works like a charm. Thanks.

On another note, I was looking at setting up a GetOtherBlackboardVariable. Can I use the same structure with replacing the Set with a Get and maybe a a variable reference for clarity.

This is really working well for us, BTW.

Hello,
I’m glad it works for you 🙂
There is already a GetOtherBlackboardVariable action task. Please make sure you have the last version from the asset store and it is there 🙂

Thanks

Got it. I had updated to the latest rev and unfortunately for me it had reactivated a couple of behaviors I had disabled. I think I returned to two revs back. Did I update incorrectly? Was caught off guard.

Hello,
Please remember to remove the old NodeCanvas folder and re-import the package anew whenever you update for best practice. Do you mean the update reactivated NodeCanvas related tasks/nodes or some other non-NodeCanvas components?

Thanks

The reactivated tasks were ND. It wasn’t that difficult to fix, actually. But, as a note, it would be a challenge down the road. I was sort of testing what Unity means “Deleting previous package”…obviously not what I anticipated. But your right about Best Practices. Sorry, to bother you on it. It was intended more as an FYI.

No worries at all and glad you got this working in the end.
Thanks!
