Issue description:
Flax is currently DPI aware, however, it is possible that different monitors have a different DPI.

To properly and reasonably elegantly implement this, I suppose that we'll need a DPI scale property for each window. And the C++ side has to take care of correctly updating it.

Steps to reproduce:
You need Windows 10 and two monitors

1. Change the scaling on both monitors
2. Open Flax
3. Move the window from one monitor to the other
4. Maximize the window

Flax version:
Flax 1.0

Hi,
if I import a FBX model, that has a reference to a not existing texture (a bought model), it will not create the material at all.
I think, it would be better, if the material would be created with appropriate settings but with a warning, that the texture could not be found.

Regards

Flax doesn't seem to support Thai (or any other non-Latin languages, I assume).

The main problem is the output in the viewport are not correctly shaped. Some glyphs are not correctly placed. This is usally caused by lacking of open type support. AFAIK only a handful of game engine do support this, including Unreal Engine 4, and probably Godot.

From skimming through the code I don't find any open type shaping function, so I assume that text shaping support is currently zero. Probably only truetype layout is supported at the moment.

Also I found that after pressing play and pause, the text somehow changed into something else entirely. Possibly access violation ?

Last but not least, When entering in the GUI textbox, all glyph are displayed as a placeholder (a box with an X inside).

Steps to reproduce:
I create a TextRender object, assign a font into it, input some Thai text ( the phrase "ตะปุ่มตะป่ำ" is used as it is short yet demonstrate this issue very well), and then flip the object upside down to get it right side up.

After pressing Play, the input text somehow changed and no longer the original text.

Then press the pause button, the input text get changed one more time.

It seems Flax is already more capable in most ways when it comes to serialization compared to Unity - notably properties, most c# objects, etc. However, I'm coming from using Unity w/ Odin Inspector, and one of the strengths of that is being able to serialize type info. As far as I can tell peeking in a prefab, it doesn't do this. Is there any consideration on implementing this?

Feature :
Git integration to directly keep track of changes in the editor.
Assets would have differents states like Uptodate, Modified, Deleted.
At first the editor would not support the whole git workflow ( just the assets states ), in order to implement other functionnality ( like pull, push , commit, branch ) one after one ( mid-term ).

Lib to use :
Since the git integration is only on the editor part, we can use libgit2sharp.

Feel free to post your opinion here below.

Double-precision floats are necessary for games that take place on extremely large scales, such as in the vastness of space. There are workarounds, but they all come with issues. If Flax Engine wishes to support extremely large scales, it would make sense to add support for double precision floats.

For further justification on this feature, please see this proposal I made for Godot: godotengine/godot-proposals#892

As for the implementation, it is possible to support compiling with both single and double precision floats at the same time, if done correctly. This can be handled in C# via preprocessor directives by defining an alias, like this:

#if REAL_T_IS_DOUBLE
using real_t = System.Double;
#else
using real_t = System.Single;
#endif

The downside is that this alias definition must be repeated in every C# file. For a more detailed example, see this file in Godot: https://github.com/godotengine/godot/blob/master/modules/mono/glue/GodotSharp/GodotSharp/Core/Vector3.cs

First , thank you for the amazing project !

I want to integrate flaxEngine into juce : https://github.com/juce-framework/JUCE

It has an opengl demo https://github.com/juce-framework/JUCE/blob/master/examples/GUI/OpenGLAppDemo.h
When you inherit OpenglAppComponent like at line 57, then you can draw your own thing using opengl.
(as at line 100
https://github.com/juce-framework/JUCE/blob/7c797c8105c2d41872e6e8d08972624f0afd335d/examples/GUI/OpenGLAppDemo.h#L100)

Thank you for you time again !

Actually 2D game development is not the main goal of FlaxEditor, but with some effort we can greatly improve the "Flax"ibility of the editor in this direction.

For now, the easiest way to create 2D stuff is to use the UI system, but it's like driving a bicycle when you have a car.

The idea would be to adapt the editor, so it can setup a 2D environnement for us :

• Face the camera to the XY plane.
• Handling user input correctly for a 2D world.
• Rotate the grid gizmo.
• And so on ...

So i'm asking if 2D support can be at least a mini-feature* of FlaxEditor.

• not a full stack 2D editor

I can work on my own to implement this feature, in order to not add workload on the existing roadmap.

I was playing around with copy-pasting actors and stumbled upon a case where a script reference turns into null.

Steps to reproduce:

1. Attach the script to an actor
2. Manually set the references in the editor
3. Duplicate the actor
4. The reference inside the object will end up being null.

public class SerializePlez : Script
{
    public class HoldsAScriptReference
    {
        public SerializePlez ScriptReference { get; set; }
    }

    public HoldsAScriptReference ReferenceHolder { get; set; } = new HoldsAScriptReference();

Currently those are the most important methods for tranforming from one coordinate system to another:

• PointToWindow and PointFromWindow
• ScreenToClient and ClientToScreen (note: there are two sorta different methods with the same name)
• PointFromParent and PointToParent

So, we have the following coordinate spaces (also see FlaxEngine/FlaxDocs#26 )

1. Screen space
2. Window space, also called client space: Should this one be DPI-adjusted?
3. Local control space, also called client space. Or just "point".

This feels a bit inconsistent. To keep the number of breaking changes down, I'd suggest renaming the C# ScreenToClient and ClientToScreen to PointToScreen and PointFromScreen.

Furthermore, I suppose window space (C# side) should be DPI-adjusted.

While editing a 4km x 4km test terrain with Flax Engine 1.0.6214, I found that the terrain editing tools were very intuitive, but unfortunately I also experienced a few annoying issues with the viewport navigation itself :

1/ [PROPOSAL] I think it would be of great help when editing a big scene if the viewport navigation behaved a bit more like in Unity, so that the cursor keys move the viewport camera :

• into the direction you are currently facing (fly mode);
• with progressive acceleration until reaching some maximum speed after a few seconds;
• with the possibility to use a higher speed factor using the Control key modifier;
• with the possibility to move vertically relatively to the direction you are facing with the Shift key modifier (or the PageUp/PageDown keys).

2/ [BUG] the values I set for "Default Movement Speed" and "Default Far Plane" in the "Editor Options > Viewport" panel seem to be completely ignored, so I'm left seeing only a very small part of the terrain, and using a much too slow speed while using the cursor keys or the mouse wheel to navigate the scene.

Rotation of my actor got reversed on X axis but working fine on the Z axis.

Steps to reproduce:

var position = _Some target position_
Actor.Rotation = Matrix.RotationQuaternion(Quaternion.LookAt(Actor.Position, position, Vector3.Up));

Workaround:

Vector3 CurrentRotation = new Vector3(-Actor.Position.X, Actor.Position.Y, Actor.Position.Z);
Vector3 TargetRotation = new Vector3(-position.X, position.Y, position.Z);
Actor.Rotation = Matrix.RotationQuaternion(Quaternion.LookAt(CurrentRotation, TargetRotation, Vector3.Up));

Issue description:

The editor doesn't remember which monitor it was last used on before closing.

It becomes a bit annoying having to drag the editor window to the primary monitor whenever starting flax.

When I place two objects on top of each other (Bottom 10kg, top 30kg), they seem to stay put, but as soon as I move the top one so that it is slightly off-center, it just starts sliding around until I make it near the center again.

Steps to reproduce:

1. Create 2 cubes, one on top of the other
2. Make top cube 30kg, and bottom cube 10kg
3. Move the top cube off-center and watch it magically slide off

When creating a new plane new Plane(new Vector3(1, 0, 0), 10);, I'd expect it to be 10 away from the origin in the positive X direction.
However, this is not the case, since SharpDX for some unknown reason assumed a negative distance D.
I'd be willing to go through the entire code and fix this.

The related SharpDX issue can be found at: sharpdx/SharpDX#551
Also relevant: https://code.google.com/archive/p/slimmath/issues/11

Steps to reproduce:

There are many ways to verify this:

> normal = new Vector3(1f, 0f, 0f);
> plane = new Plane(normal, 10f);
> plane
[A:1 B:0 C:0 D:10]
> otherPlane = new Plane(normal * plane.D, normal);
> otherPlane
[A:1 B:0 C:0 D:-10]

The following code creates a plane and a ray, with the same direction. Logically speaking, the ray should intersect the plane. But that's not the case. You need a ray with the opposite direction, because of the negated D.

Plane p = new Plane(new Vector3(1, 0, 0), 10);
// [A:1 B:0 C:0 D:10]
Ray r = new Ray(new Vector3(0, 0, 0), new Vector3(1, 0, 0));
// [Position:X:0.00 Y:0.00 Z:0.00 Direction:X:1.00 Y:0.00 Z:0.00]
> bool b = r.Intersects(ref p);
// false

Issue description:

Hi! Congratulations on your launch! Foliage is unpaintable on high terrain. For some reason, foliage is not being placed on terrain that has some height. Also, already placed foliage doesn't adapt to terrain changes.

Steps to reproduce:

Bug 1: Foliage is unpaintable on high terrain.

1 - Open any project
2 - Create terrain
3 - create basic foliage brush with any model, say, a capsule
4 - make some hills, slopes, and etc in terrain editor using sculpt tools
5 - paint foliage on highground
6 - foliage will not be placed.

Bug 2: Foliage is unpaintable on high terrain.

1 - Enter sculpt mode in terrain
2 - change height values underneath already placed foliage.
3 - see that foliage won't move, it will remain there.

Minimal reproduction project:
None, reproducible in any empty project.

Visject Graph Improvements

TODO:

• .xyz → Mask XYZ
• .zyy → Unpack Vector3 + Pack Vector3
• And also .color.x, which selects the color input and generates a pack vector3
• Select Unpack Material Layer Node → Type .color → selects the color output
  • Add check to make sure that you can't create outputs that start with a number
  • Or maybe use the Visject context menu for this?
• Format graph part, as specified by comment.
• Bring brackets into view like the context menu
• Selecting connections with the keyboard
• Removing connections with the keyboard
  • If you've opened the context menu and delete whats there, the context menu should close
• Paste number → Visject Node
  • Or in general, if the text is short/can be parsed
• Visject formatter special cases
  • Comments
  • Nodes that are attached to the main node should also be able to move up
• Less random _selectedConnectionIndex order
• Commentception: Nested comments should work
  • Simple but so helpful: need an option to configure the "z-index" of a comment node in graph editors.
• Word wrapping for the comment title
• Local variable nodes
  • Set and get nodes (distinguish from parameters)
  • When selecting, subtly show the implicit connections to the getters/setters

Make it way cooler:

• Evaluating expressions and turning them into nodes
  • *5 should turn into 2 nodes, a multiply and a float node
  • user could type (3 + Param1) * Param2.xyz + Texture or sth similar and the nodes would pop up
• Realtime (while you are typing) expression-to-node conversion
• Multi-Node editing
• Check out other tools for ideas
  • Houdini
  • xNode
  • https://www.knotend.com

Random Ideas

• Double clicking on a node title to edit it and change it's type

• Show which connections it will get connected to! (So, evaluate it while the user is typing!)

• Deleting a node with the backspace

• Editing the values of the currently selected node with the keyboard

  • e.g. Typing bias and scale (0.1, 5)
  • e.g. Selecting a float and typing (3, 5.7)
  • This idea is the reason why the "click on node and start typing" behavior was changed to "click on box and start typing"

• Clicking on an input box and then typing stuff like = somenodename.x

• Accessing nodes that are already on the graph

  • Named nodes
  • e.g. Select a node and type shadow bias strength =
  • Named outputs (Color, Mask, Emissive, Normal, etc.)

• Navigating between nodes that are on the graph with the keyboard

  • Either by position (up → node above, up-left → node above and to the side)
  • Or using the tree (left → parent, right → first child, down/up → previous/next neighbor)
  • If a box is selected, the behaviour is still undefined

• Only show things that make sense (when you are at an output box, only show things with an input box)

• Travel along the nodes after creating a new one (Aka which box should be selected after typing 3 * sin 5) (see What if we reached the end (nextBox == null)? Do we travel along the nodes?)

• Collection as basic type

  • A for loop outputs a number array (what about the impulses?)
  • A foreach loop outputs a something array
  • A while loop outputs an impulse array
  • Some skeleton animation nodes like the blend poses node can take an array
  • e.g. for i in 0..10 --> vector3 --> spawn 3D model

• Hover over connection

  • Select connections (mouse click)
  • Right click connections

• Make errors/warnings more visible

  • Unknown type
  • Attached to a disabled box

• https://forums.unrealengine.com/unreal-engine/marketplace/120671-blueprint-assist-plugin

• Alt+Drag to drag a node and all of its inputs ("children")

  • Find children by traversing the tree until the comment ends/a comment starts

• Switch on bool with condition is hard to find

  • if(3<5)

• local variables or named nodes

  • don't allocate an actual variable
  • just use it to prevent having to drag nodes from paris to berlin

• expose programmatic ways to add custom nodes? or redesign it?

• Smarter node positioning on creation (don't position nodes above each other)

• Collapsible nodes

• Collapsible comments

• Material functions for other visject graphs

• Nodes that are just a title with an output

• Smaller boxes, potentially outside of the node

• Grid and align to grid

• Subtly draw connections over nodes

• Connecting sibling nodes when deleting a node

• Fuzzy search: https://jeremymikkola.com/posts/2019_03_19_rules_for_autocomplete.html

• organizational ports/nodes that can have more than one target/connection coming off of it

• Auto formatting ideas

  • Straight connections?
  • W2Wizard's formatting improvements

• https://www.unrealengine.com/marketplace/en-US/product/79b5dec349994783906e4ccc9191452d?sessionInvalidated=true

• Arrow key navigation: Select box itself by tapping "up"

• Check out blender nodes

  • Automatically/use a shortcut to hook up node when dragging it on top of a connection
  • Use a shortcut to move existing connections to the nearest spot when hooking up a new connection

• directly write code into a node, like the custom HSLS node but well for Scripting

• Paste limited subset of shader code

• Copy as HLSL

• Take a few nodes and collapse them into one

  • And make it possible to expand them again
  • And reasonable collapsings should be suggested automatically

• ideally you'd be able to select a bunch of boxes, group them into a single box, and then see a source text representation of what they calculate (if it's "simple" in some sense)

• Zoom out: display smaller version of nodes (only title)

• Some inputs have "implicit" values, like every texture implicitly has the texture coordinate (right?). That could be made more clear or those implicit inputs could be "quickly expanded/added".

• Language Server Protocol Client: What if Visject were to generate code in the background, and then ask a real language server questions like "what autocomplete suggestions make sense here" and "what are all the data types" and "are there any errors". Of course that'd have a very real overhead, but depending on how complex the language is, it might have some very neat benefits.

Issue description:
The dockable windows, like the material windows, are a bit odd when dragging. They sometimes jump to a different position when you drag them.

This happens because in the engine core, the mouse position doesn't get updated as soon as the mouse is above a window title bar.

This piece of code doesn't get triggered. I'd gladly fix it, but am unsure how to best proceed.

Steps to reproduce:

1. Open a material window
2. Move your cursor below the title bar, at the very left of the window
3. Move your cursor onto the title bar
4. Move your cursor all the way to the right on the title bar. Make sure to stay on top of the title bar while moving.
5. Start dragging
6. The window jumps

Basically just follow that mouse path ^ and start dragging

Hi,

I often use bought model packs for my projects. So, I need to import a lot of models. At the moment, if I decide to import the materials, a subfolder for each model will be created, even if the models use the same material name (e.g. "MyMaterial").

It would save a lot of work, if you have an option to reuse existing materials by name or set an subfolder to locate the desired materials. So, that you have one subfolder "Materials" for the models you choose. With that, you can create logical groups of models and materials like buildings, vehicles, props etc. I hope, you can understand, what I want to achieve :D

A second improvement would be, to assign a material to multiple models at once.

Proposal description:
Debug Log, Error, Warninge etc. should always have stack trace to find stray logs.

Possible resolutions:

1. Debug should have full stack trace

• Very nice/Usefull
• Verbose

• Slow
• Use a a lot of memory
• Make a bloat in log file

2. Debug should have name of the namespace::Class.Method + line nubmer or File name + line number

• Clean
• Fast
• Usefull
• Small size

• Still might be thought to identify in edge cases
• Doesn't provide context (sometimes required, but one can add it themselves)
