electronicnodes's Issues

No hover on short wires

Hover are disabled on corners of wires to be a bit cheaper on performance.

Thing is it's also missing on short link, so you can't hover a short wire.
I'll just re-enable it.

Add options to draw straight lines for close pins

Add an option to draw straight lines for close pins for users that put variables onto others:

Failed to rebuild as a project plugin

Describe the bug
I wanted to rebuild the plugin as a project plugin. It worked some days ago but now it seems it can't find 'AnimGraphConnectionDrawingPolicy.cpp'

here is the error log :
D:\git\Altexp\ALTEXP_UE4\Plugins\ElectronicNodes\Source\ElectronicNodes\Private\ENAnimGraphConnectionDrawingPolicy.h(8): fatal error C1083: Impossible d'ouvrir le fichier include�: 'AnimGraphConnectionDrawingPolicy.cpp'�: No such file or directory.

To Reproduce

1. Copy "ElectronicNodes" folder from engine plugins to project plugins
2. Try to rebuild from source

Environment (please complete the following information):

• Unreal Engine version: 4.23
• Operating System: Windows 10 64bits

Add support for Behavior Tree

It's a bit weird, but it works:

(Might be improved in the future)

Disable HotPatch by default

I'm not quite sure that a lot of people use the hotpatch feature a lot, and it sometimes can bring some bugs...
cf #44

I think I'll disable it by default (and of course, people will be able to activate it back)

Support for Control Rig

I love your plugin, but it seems to not activate with Control Rig graphs? While that is still an experimental feature in the form of a plugin, it is very much usable already and some of us are developing for it.

Automatically surround the nodes.

It is possible to implement, to automatically detect the node and move around them and not be under the nodes ? Thank you !

automatically straight wires

Is it possible to integrate a function so that wires are always straight? You always have to correct this manually with the "Q" key

Add support for custom graphs

Some users want to activate Electronic Nodes for a specific type of graph.

I should add an array of string for compatible graphs.

Global settings fail

Global settings sometimes reset some options (like the wirestyle)

Connections disappear in control rig graph

Describe the bug
Selecting nodes in control rig graph causes connections to disappear.

To Reproduce

1. Make some connections in a control rig
2. Highlight the connected nodes

Expected behavior
The connections don't disappear.

Screenshots

Environment (please complete the following information):

• UE 4.26.1
• Windows 64bit

Additional context
Only happens in the control rig graph from what I could tell.

Log spam on 4.24

Spaming shcematyp log on 4.24

Improve Behavior Tree (and line based graph)

Behavior Tree looks kinda off with Electronic Nodes, this should be improvable...

4.22 Android and iOS packaging warnings

Describe the bug
Building the plugin gives warnings on 4.22 when building for android / iOS - these use clang as compiler.

To Reproduce
Steps to reproduce the behavior:

1. Package for Android

Expected behavior
No warnings shown

Screenshots

Environment (please complete the following information):

• Unreal Engine version: 4.22
• Operating System: Windows

Add bubbles on wires connected to selected node

Describe the solution you'd like
I would like to see the bubble lines only come from the selected node. Maybe node color can change once selected as well.

Electronic Node in Reference Viewer

Is it possible to have straight lines in reference viewer ?

Drop FPS in Editor

Describe the bug
In a few times, I got drop FPS when working on the blueprint, it causes slow down everything like adds a node, pan/zoom blueprint, open another blueprint, ... The more blueprint was open, the more FPS will drop. And when it too slow, it causes a crash.
I used the plugin "Electronic Nodes" with plugin "Assist Blueprint". For the first time, I thought the reason is plugin "Assist Blueprint" because it always auto - position when adds nodes and I turn off auto - position, but there aren't better. After that, I try to turn off one of each plugin. When your plugin was turned off ("Assist Blueprint" still on), the editor was smoother.

Expected behavior
This issue just happens sometimes, sometimes is fine and some don't. Just like the longer I work on, it will happen. Or I open too much blueprint (like 7-8 blueprint at once). But when I report this issue, I just open 1.

Missing ModuleInterface header

It seems that the "Modules/ModuleInterface.h" include is missing in ElectronicNodes.cpp.

It's silent since it is already included by the engine before, but it should include it anyway.

Add support for Gameplay Abilities

When creating a gameplay ability, it should be possible to make Electronic Nodes work.

Connections disappear in Animation State Machine

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:
It's easiest to just open the 3rd person example
Open ThirdPerson_AnimBP
Open the default animation state machine (Animation Graphs -> AnimGraph -> Default)
Connections aren't there

Screenshots

• UE 4.26.1
• Windows 64bit

Additional context
Add any other context about the problem here.

Make it work for Niagara script

Add Niagara script support.

Experimental UE5 support

Since more and more people want to use Electronic Nodes on UE5, I'm adding experimental support to it.

As UE5 is not production ready (nor the marketplace allow official support of it), it's just experimental, meaning it could break at any UE5 update.

Problem with packaged UE4 projects not loading

After packaging a project in the stock version 4.24 of the Unreal Engine, it appears, that I'm somehow unable to start the packaged game. Whenever I try to start it, the windows loading icon pops up for a few seconds, but the game isn't loading at all.
Disabeling the plugin before packaging fixed the problem for me, but you always have to load up the editor twice in order to enable, disable it.

To Reproduce

1. Package a project in the development build configuration.
2. After the packaging is done go ahead and try launching the now packaged project using the .exe.
3. You can now see the windows loading icon for a few seconds, but nothing else.

Expected behavior
Normaly, the game should launch after executing the .exe.

Environment (please complete the following information):

• Unreal Engine version: 4.24
• Operating System: Windows 64bits

With Ribbon on, do not separate out wires coming from the same pin

Also see this post.

Example image:

Any chance support UE5？

I know its too early to ask, But I cant leave this plugns. The original is ruining my eyes.

State machine graph has no wires

This bug was introduced by 3.0. It's fixed and ready to deploy.

Crashes with HotPatch since 3.0

Some users report crashes probably due to HotPatch.

[BUG] Invisible Transition in Annim BP

Describe the bug
Once the plugin is installed the line of the transitions desapears .

To Reproduce
Install and enable the plugins
Open or create an annim Bp and go inside the state machine .
creates rules and link them togethers .

Expected behavior
Lines of the transitions should appears .

Screenshots
With the Plugin Off :

With the Plugin On :

Used settings :

Environment (please complete the following information):

• Unreal Engine version: Ue 4.26.1
• Operating System: Windows 64bits

Additional context

Even if i chooses to in the plugins options to desable it for annim graph ( or for everythings ) it still hide transition . Only way is to desable the plugins wich make my life harder .

Startup pop-up crashes the engine in Commandlet mode

Describe the bug
Title says it all.

To Reproduce

1. Enable the plugin
2. Remove the .ini file used to determine first launch (simulate a first launch)
3. Launch a commandlet

Expected behavior
The plugin does not crash the engine.

Environment (please complete the following information):

• Unreal Engine version: 4.26 and 5.00
• Operating System: Windows 10

Alignment bug with Mangattan on Behavior Trees

Small bug with Manhattan on behavior tree

Weird behavior with manhattan style

There are some weird behavior on some positions with manhattan style wires:

Probably introduced by #35

Have to disable to push build

Remember to be specific and concise.
Loving your plugin but anytime I push my build to my team I have to disable it otherwise the individuals who do not have the plugin cannot load the project on 4.22.3

Add global settings

Just like Darker Nodes: hugoattal/DarkerNodes#125

No bubble on animation blueprint

There're no bubbles on animation blueprint.

Better organization of many in-nodes

After using the plugin for quite a while now I gotta say that I love it and I've been recommending to everyone that wants a more organized blueprint. The text below is my only issue with the plugin and something that really really bothers me and I hope you can solve it :)

Would it be possible to have a better treatment of in-nodes? Currently it's common to have a situation that looks like this:

But when you drag the node a bit further we can have a MUCH cleaner look like this:

Even tho the second effect could be achieved in the first image the plugin currently doesn't do a very good job at untangling these situations. And in those cases we could end up with very unnecessary space between our nodes just to have a cleaner look.

Compatibility with Node Graph Assistant

Hey man, sorry for the second issue on your other plugin :P

While trying out Electronic Nodes alongside the absolutely amazing Node Graph Assistant I found some incompatibilities.

https://youtu.be/ia3JR2hNil0

For instance the auto-snap node and line recoloring do not work when Electronic Node is turned on. Could you add support for Node Graph Assistant? That's a really amazing must-have plugin for working with nodes.

Add new version popup

I think it would be cool to display the new features/bux fixes on new updates.

Crash when launching on a Oculus Quest

Describe the bug
I'm not sure if this perhaps is expected behaviour, but thought I'd mention it. When I try to launch a build on a Oculus Quest device (Android / Vulkan) the process crashes once the app is about to start on the headset.

To Reproduce
Just Press launch and wait for the build and upload to finish, then once the headset is activated it crashes immediately.

Expected behavior
Built app should start, and does so without problem once I disable the plugin from UE4.

Environment (please complete the following information):

• Unreal Engine version: UE 4.24.3
• Operating System: Windows 10 x64

Unnecessary #include ".cpp"

Hi!

Found recently this line in ENAnimGraphConnectionDrawingPolicy.cpp:3
#include "AnimGraphConnectionDrawingPolicy.cpp"

Is this necessary to include this .cpp file into other .cpp? In 4.25 I see not so much reasoning for this (no reasons at all to be clear).
What was the point doing so?

Source code of included file:

Hidden connection arrows in State Machine view with Logic Driver plugin

Electronic Nodes plugin conflicts with Logic Driver Plugin.
Logic Driver StateMachine view doesn't have any connection node visual.

Steps to reproduce the behavior:

1. Install Logic Driver plugin
2. Create or open a StateMachine asset
3. Try to make any connection on State Machine graph
4. See no connection is drawn.

Expected behavior
In-plugin style State Machine connections are visible (Electronic Nodes override style / Logic Driver native style)

UE5 change to FGraphSplineOverlapResult breaks compilation

Describe the bug
The constructor for FGraphSplineOverlapResult now has an additional parameter (bool InCloseToSpline) that was not present in 4.X. This causes building for UE5 to fail.

To Reproduce
Steps to reproduce the behavior:

1. Download/Install a fresh copy of ElectronicNodes for UE 4.27.0
2. Follow build steps from https://github.com/hugoattal/ElectronicNodes/wiki/How-to-install-Electronic-Nodes-on-previous-version-of-the-engine%3F-On-custom-build%3F for UE 5.0.0 Early Access 2
3. When building fails, logs will show

[4/7] Module.ElectronicNodes.cpp C:/BUILDPATH/HostProject/Plugins/ElectronicNodes/Source/ElectronicNodes/Private/ENConnectionDrawingPolicy.cpp(151): error C2440: '<function-style-cast>': cannot convert from 'initializer list' to 'FGraphSplineOverlapResult' C:/BUILDPATH/HostProject/Plugins/ElectronicNodes/Source/ElectronicNodes/Private/ENConnectionDrawingPolicy.cpp(151): note: No constructor could take the source type, or constructor overload resolution was ambiguous

Expected behavior
Build completes successfully

Environment (please complete the following information):

• Unreal Engine version: UE 5.0.0 Early Access 2
• Operating System: Windows 64bits

Additional context
I understand that this is not a priority, and it would not make sense to fix this in the baseline as it will break the project for UE_4.X. I just wanted this documented in case it helps someone else trying to perform this build.

This can be fixed/bypassed by updating ENConnectionDrawingPolicy.cpp line 151:
... = FGraphSplineOverlapResult(..., ..., ..., ..., ..., false);
Documentation on the new constructor is here:
https://docs.unrealengine.com/5.0/en-US/API/Editor/GraphEditor/FGraphSplineOverlapResult/
The added item is:
bool InCloseToSpline

Wrong display for wire with low angle

Wires with low angle are drawn are straight line, even when the endpoint is far from being in the direction of the startpoint.

Fixed, will be release in 2.1

Allow exec wires to be aligned left rather than right

Currently exec nodes wires curve as right as possible, near the receiving node. Would it be possible to align them left, near the outgoing node?

Example image:

Freezing when using Swap node left/right when moving in front of or behind something with multiple node directions (ex: a montage)

Describe the bug
When Swap node left/right on something like a print string, is the user moves it to code with multiple node directions (ex montage: completed, interrupted, on notify begin, ect..) the project will crash

To Reproduce
Steps to reproduce the behavior:

1. Go to a blueprint
2. Click on a print string
3. use control shift and the left or right arrow to move the print string in front of or behind a montage
4. See error

Expected behavior
Swap node left/right works on code with multiple nodes directions

Screenshots
Swap node left/right crashes on code with multiple nodes directions

Environment (please complete the following information):

• Unreal Engine version: UE 4.22
• Operating System: Windows 64bits

Additional context
The problem seems to get worse with more stuff present (if the engine is working harder)
had a repro rate of 5/5
Tested it on another users computer, same result. Although we were working on the same project.

Ribbon does not alway offset when it should

Describe the bug

In certain conditions, ribbon does not offset when it should.

(Note: It's fixed and will be release in 2.1)

Packaged game issue with the plugin

Packaged game doesn't start because electronic nodes plugin is not loaded. Didn't have any issue like this on 4.23

Unreal engine version: 4.24.

Expected behavior
Packaged game shouldn't contain any info about electronic nodes editor plugin.
