Reply To: How to set icon for custom task?

[lorewap3]

Excellent! While creating some other tasks, I ended up making another change to Task.cs . I modified the access for the icon property so I could override it based on values in the children:
public virtual Texture2D icon

For example I have a IsFacingDirection ConditionTask and I override the icon based on the setting:

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

public override Texture2D icon {     get     {         if (leftIcon == null)             leftIcon = UnityEditor.AssetDatabase.LoadAssetAtPath<Texture2D>("Assets/Sprites/UI/BehaviorTreeIcons/Pathing/DarkIsFacingLeftIcon.png");         if (rightIcon == null)             rightIcon = UnityEditor.AssetDatabase.LoadAssetAtPath<Texture2D>("Assets/Sprites/UI/BehaviorTreeIcons/Pathing/DarkIsFacingRightIcon.png");           if (direction == Direction.Left)             return leftIcon;         else             return rightIcon;     } }   /// Private reference to left/right icon textures private Texture2D leftIcon; private Texture2D rightIcon;

The icon doesn’t update immediately if the value is changed, but that’s ok. I’m sure you have texture caching done in the background. I just wanted to let you know about this use-case. If possible to make the icon refresh somehow that would be nice, but again it’s not worth a performance hit.

Thank you for your support, Gavalakis. You created an amazing product, and is truly one of the best designed assets I have come across. I will be using this for years to come. I really appreciate it!
