How to Register NavigationTarget During Game

[IbrahimParticipant]

Hi,

The function:

NavigationManager.Instance.GetNavigationTarget("target_name");

returns null. I found that the reason for this was that the player is placing the “target_name” during the game, so it is NOT registered by the NavigationManager. Do you have a solution for such a problem?

I read in the API that registration is done during the AWAKE function. How can I register these new targets during the game?

How are you creating the rig during runtime? Is it from a prefab or in code? I know you can use the NavigationTargetRig.CreateRig helper method which returns a new NTR. I assume it registers it also.

Rig is not created at runtime. Once the user drag and drop image from GUI a GameObject is instantiated that has NavigationTarget child gameobject.

I remember someone having a similar issue with (I think) the Waypoint Route/Network when it was being created at runtime or from a placed prefab (including me). The process should be similar so I will mess with it when I get home and try to flesh it out.

EDIT: Try a call to _MyNavigationTargetRig.Serialize() and see if that registers it correctly.

Thank you for your reply, I searched the API and found it, but I do not know how to set a reference to it, maybe you can help me.

NavigationTargetRig  _MyNavTarRig = ??

Any answer for this please…

Sorry I have been very busy. Well you said your code places an instantiated prefab when a button is clicked so you would just grab the rig component from the prefab and call it that way.

Such as

void Start()
{
  var m_navTargetRig = GetComponent<NavigationTargetRig>();
  m_navTargetRig.Serialize();
}

Thank you for your help.

I found out that registering the navigation target is not what I needed to solve my problem. I found out that changing the name of the navigation target this way:

instantiatedObject.transform.FindChild("my_nav_target").name = "nav_target_" + i;

did not change the NavigationTarget, but only the mountPoint name. And this why my statement:

NavigationManager.Instance.GetNavigationTarget("my_nav_target_" + i)

returns NULL.

The correct way to change the NavigationTarget name is:

instantiatedObject.transform.FindChild("my_nav_target").GetComponent<NavigationTargetRig>().Target.TargetName = "nav_target_" + i;

Very nice. Glad you got it working!
