Feature request: Going backwards along a path

OllyMUKOllyMUK
in Technical Q&A

Hi

Can I request a feature? Is it possible to have the Move Along Path action have a new option to Reverse along a path? That is to start from the chosen path node (closest, specified etc) and then go backwards along it from the current node down the node numbers back to the zero node?

Use case is to have a path that takes an NPC to an object, or area, have them do something, then travel back to the starting point along the same path, but going from the highest node to the lowest.

Currently I'm having to create a path to the area, then a path out, which is just duplicating work.

Apologies if this is already in there somewhere.

Thanks

Olly

    It may be possible already, if I'm following you correctly.

    A Path's Path type field can be set to Reverse Only to have characters move backward along it, but in your case you might be best off setting to Loop, and then attaching a "Node Cutscene" on the end of it that causes the NPC to do their thing before moving back.

    Sorry I know that this is an old thread, but what'd be great is an action that can set the path direction (to forward / back / ping-pong, etc). That way when your character reaches the end of the path, your final action could be to flip it, when the player wants to go back it's ready to go.

    Here's a custom Action that'll do it:

    using UnityEngine;
using System.Collections.Generic;

#if UNITY_EDITOR
using UnityEditor;
#endif

namespace AC
{

    [System.Serializable]
    public class ActionPathType : Action
    {

        public int constantID = 0;
        public int parameterID = -1;
        public Paths path;
        protected AC_PathType pathType;


        public override ActionCategory Category { get { return ActionCategory.Hotspot; }}
        public override string Title { get { return "Rename"; }}
        public override string Description { get { return "Renames a Hotspot, or an NPC with a Hotspot component."; }}


        public override void AssignValues (List<ActionParameter> parameters)
        {
            runtimePath = AssignFile <Path> (parameters, parameterID, constantID, path);
        }


        public override float Run ()
        {
            if (runtimePath)
            {
                runtimePath.pathType = pathType;
            }
            return 0f;
        }


        #if UNITY_EDITOR

        public override void ShowGUI (List<ActionParameter> parameters)
        {
            ComponentField ("Path:", ref path, ref constantID, parameters, ref parameterID);
            pathType = (AC_PathType) EditorGUILayout.EnumPopup ("New path type:", pathType);
        }

        #endif

    }

}

    Legendary! Thank you so much @ChrisIceBox

    I actually came here to post my own custom action, but your version is better (natch!)
