Visualizer hard to see with dark mode on

[ashblue]

Currently hard to read the visualizer with Dark Mode. Would be good if more neutral colors were used on the connecting lines.

Great first issue if somebody wants to tackle it.

any update on this? the PR seems stalled..

[ashblue]

Haven't touched any AI for a while so I've been working on other libraries. Somebody pushed up a PR to get this going but it still needs some work.

Issue is mostly done here. Needs some cleanup to be finished #69

In order to make dark mode easily visible I changed the colors of the NodeFaders based on whether the dark mode is on or not.

using UnityEditor;
using UnityEngine;

namespace CleverCrow.Fluid.BTs.Trees.Editors {

    public class NodeFaders {
        public ColorFader BackgroundFader { get; } = new ColorFader(
            EditorGUIUtility.isProSkin ?
            new Color(0, 0f, 0.8f) : new Color(0.65f, 0.65f, 0.65f), 
            EditorGUIUtility.isProSkin ? 
                new Color(0f, 1f, 0f) : new Color(0.39f, 0.78f, 0.39f));
        
        public ColorFader TextFader { get; } = new ColorFader(
            EditorGUIUtility.isProSkin ?
                Color.black : Color.white,
            EditorGUIUtility.isProSkin ?
                Color.white : Color.black);
        
        public ColorFader MainIconFader { get; } = new ColorFader(
            new Color(1, 1, 1, 0.3f), new Color(1, 1, 1, 1f));
        
        public ColorFader LastStatusFader { get; } = new ColorFader(
                Color.grey, Color.white);

        public void Update (bool active) {
            BackgroundFader.Update(active);
            TextFader.Update(active);
            MainIconFader.Update(active);
            LastStatusFader.Update(active);
        }
    }
}

I made the StatusIcons saturated and managed their darkness through code (they were really dark which didn't fit for dark mode):

Finally, because the last task status overlaps with the names of tasks if the text is long, I put the task status at the top right of the nodes.

public class NodePrintController {     
private void PrintLastStatus (Rect rect) {
            const float sidePadding = 1.5f;

            var icon = BehaviorTreePrinter.StatusIcons.GetIcon(_node.Task.LastStatus);
            icon.Paint(
                new Rect(
                    rect.x + rect.size.x - icon.Texture.width - sidePadding,
                    // rect.y + rect.size.y - icon.Texture.height - sidePadding, // original code
                    rect.y, // new code
                    icon.Texture.width, icon.Texture.height),
                _faders.LastStatusFader.CurrentColor);
        }
}

Connected PR hits most of this. I'll cross reference the code you posted when I run through it.

Actually the most problem comes from NodeBoxStyle.cs and default style of GUI.skin.box

    Style = new GUIStyle(GUI.skin.box) {
        border = new RectOffset(1, 1, 1, 1),
        normal = {
            background = texture,
        },
    
    };

changing that to

        Style = new GUIStyle {
            border = new RectOffset(1, 1, 1, 1),
            normal = {
                background = texture,
            },
            
            alignment = TextAnchor.MiddleCenter,
            padding = new RectOffset(4, 4, 4, 4),
            margin = new RectOffset(4, 4, 4, 4),
            overflow = new RectOffset(0, 0, 0, 0),
            stretchWidth = false,
            stretchHeight = false,
        };

solves the box background issues.

@darkgnostic Fascinating. This would explain some things across several different packages I'm seeing if this fixes the issue.

[ashblue]

@darkgnostic yep this fixes the issue. Sorry for the delay. I'll get a patch out before the week is over
