Moving waypoints at runtime

[littlegamesParticipant]

Hi, I’m fairly new to Rain (although I’m well familiarised with Unity) and I’ve encountered a few problems when trying to move a waypoint at runtime. Apologies if there are blatant mistakes in this code, I’m still getting the hang of Rain!

Although there will inevitably be some problems in my code, I can’t test it yet because I’m getting compiler errors with some Rain-specific classes. ‘MoveLookTarget’ and ‘WaypointSet’ both ‘do not exist in the current context’ which I guess means I haven’t added the right classes at the beginning of my file, however I’m not sure which ones I could further add; I’ve read the handy documentation and added the ones they seem to require, and I even tried adding every single one and they’re still not being recognised! I’d hugely appreciate a little bit of guidance from someone who could give me a tip as to how to fix this error

Here’s my code (heavily influenced by the samples!):

using UnityEngine;
using System.Collections;
using RAIN.Core;
using RAIN.Action;
using RAIN.Navigation;
[RAINAction]
public class RainTest : RAINAction
{
	private GameObject _avoidTarget;
	private MoveLookTarget _nextMovePoint;
	private WaypointSet _wpSet;
	private static int _wpCurrent = -1;
	private RaycastHit hit = new RaycastHit();
	private Ray ray;
	private Vector3 location;
	public RainTest()
	{
		actionName = "RainTest";
	}
	public override void Start(RAIN.Core.AI ai)
	{
		if (Input.GetMouseButtonDown (0)) {
			Debug.Log ("clicked");
			ray = Camera.main.ScreenPointToRay (Input.mousePosition);
				if (Physics.Raycast (ray, out hit, 10000)) {
					Vector3 (hit.point.x, (hit.point.y), hit.point.z);
					_wpSet = NavigationManager.instance.GetWaypointSet ("Waypoint Route");
					//Create the movelook object and define the position
					_nextMovePoint = new MoveLookTarget () { VectorTarget = location };
					ai.Motor.moveTarget = _nextMovePoint;
					base.Start (ai);
				}
		}
}
	public override ActionResult Execute(RAIN.Core.AI ai)
	{
		if (!ai.Motor.IsAtMoveTarget)
		{
			ai.Motor.Move();
			return ActionResult.RUNNING;
		}
		return ActionResult.NONE;
	}
	public override void Stop(RAIN.Core.AI ai)
	{
		base.Stop(ai);
	}
}

MoveLookTarget requires RAIN.Motion
WaypointSet requires RAIN.Navigation.Waypoints

What are you trying to accomplish with your code? Just moving to a location that the player clicks?

Thanks so much, that’s solved it!

Yes, I know I could easily move to a location without waypoints at all by just setting a location and moving in a straight line, but I really like RAIN’s pathfinding and obstacle avoidance. Is there a simpler way to do this?
Thanks

We will have dynamic obstacle avoidance in a coming patch that will allow the navigation mesh to refresh at runtime.

Also check out our new tutorial series. http://rivaltheory.com/forums/topic/get-started-with-rain-2-0-10-video-walkthrough/

Let me know if you have any other questions.

Best,

Thanks for the response Jester. The tutorials look good - I’ll have a look tomorrow and hopefully it’ll teach me many new things.

[JesterKeymaster]

They surely will. Let us know if you have any questions.

Best,
Jester
