Variable names lost on custom nodes

[dsedovParticipant]

I’ve created custom datatypes

1 2 3 4 5

////ECO OBJECTS [Serializable] public class BBEcoNPC : BBVariable<EcoNPC>{} public class BBEcoNPCAbility : BBVariable<EcoNPCAbility>{} public class BBEcoNPCAbilityList : BBListVariable<EcoNPCAbility>{}

Defined their data like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

using UnityEngine; using System.Collections; namespace NodeCanvas.Variables{ [AddComponentMenu("")] public class EcoNPCAbilityData : VariableData{ public EcoNPCAbility value; public override object objectValue{ get {return value;} set {this.value = (EcoNPCAbility)value;} } } }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

using UnityEngine; using System.Collections.Generic; namespace NodeCanvas.Variables{ [AddComponentMenu("")] public class EcoNPCAbilityListData : VariableData{ public List<EcoNPCAbility> value = new List<EcoNPCAbility>(); public override object objectValue{ get {return value;} set {this.value = (List<EcoNPCAbility>)value;} } } }

Now I have created a node which copies this data to Blackboard variable:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

namespace NodeCanvas.Actions{ [Category("Eco")] [Name("Import NPC")] public class NCEcoImportNPCData : ActionTask { [BlackboardOnly] public BBEcoNPCAbilityList abilities = new BBEcoNPCAbilityList{blackboardOnly = true}; protected override string info{ get {return "NPC -> $";} } protected override void OnExecute(){ abilities.value = agent.transform.GetComponent<EcoNPC>().abilities; EndAction(); } } }

the problem is that when the tree is reloaded (I change script and the node editor says “Recompiling”), the variable name is gone. Attaching before and after picture:

Actually none of my nodes that use custom BB types save the values in the inspector (regardless if it is a temp variable, bb variable or something else)

Ohhh… nevermind. Forgot to put [Serializable] in front of every declaration like this:

1 2 3 4 5 6 7 8 9

////ECO OBJECTS [Serializable] public class BBEcoNPC : BBVariable<EcoNPC>{} [Serializable] public class BBEcoNPCAbility : BBVariable<EcoNPCAbility>{} [Serializable] public class BBEcoNPCAbilityList : BBListVariable<EcoNPCAbility>{}

Hello,

Yep, you have to mark them all as [Serializable] 🙂

By the way:

– You can just use the [BlackboardOnly] attribute without initializing the BBVariable like {blackboardOnly = true}. This was the old way of doing this and that’s why some tasks still have it which I have not changed yet 🙂

– You can have your classes in any namespace you want if you have your own ECO namespace for example. They don’t have to be in the NodeCanvas.Variables or NodeCanvas.Actions respectively.

– In your info property you can use for example abilities.ToString() to get a nice formated text if you want like:
{return “NPC -> ” + abilities;} You can do this for any BBVariable of course.

– The agent is a Component type. You can GetComponent from it directly without going through the .transform
agent.GetComponent().abilities;

Just saying 🙂

Cheers!
