Blueprint Assist Plugin

[T.S999]

My engine is crashing from time to time after a complex blueprint formatting. From what I tested it causes because of the use of "Hide Unconnected Pins" button.
I'm using 2.0.2 (engine 4.23). Can you test it please?

Hi TalShabi, I've opened up an issue for you on github: https://github.com/fpwong/BlueprintAssistWiki/issues/13

Could you post a screenshot of the blueprint which causes the crash? I briefly tested the usage of Hide Unconnected Pins on a custom struct but was unable to recreate the crash.

Update 31 January 2020 (v2.1.0):

• Feature: Formatting algorithm accounts for surrounding comment boxes (enable via the setting "Account for comments when formatting")
• Misc: Made toolbar less ugly and added more settings
• Misc: Pin selection is now disabled for knot nodes so you can now move them with arrow keys
• Misc: Added setting to disable the caching notification: "Disable Caching Node SIze Notification"
• Misc: Knot nodes will be added to selection after formatting if all formatted nodes are selected
• Bug fix: Crash related to empty macros
• Bug fix: Issue where selective formatting command (Shift+F) would not format parameter nodes correctly
• Bug fix: Crash related to expanded formatting style

I'm using 4.24.2 and I can't use any shortcuts except Tab key ( for creating nodes).
no shortcuts works for me and I'm sure I'm doing something wrong.
what should I do?

There is one case where the other hotkeys are disabled. By default this only occurs when using non-blueprint graphs (e.g. the Material Editor / Niagara graphs).

If this is happening to you on blueprint graphs, perhaps somehow the setting "Use Blueprint Formatting For These Graphs" was cleared? It should have 5 elements in it:

• EdGraph
• GameplayAbilityGraph
• AnimationTransitionGraph
• AnimationGraph
• SoundCueGraph

yes , I was using Material Editor, Niagara graphs.
would be possible for next release or It is not planed?

I might try to work on them for a bit and see how it goes but I doubt I will be satisfied with the result. Don't expect much for the next release :P

PSA: The plugin currently has a common crash, related to formatting macros / chains of parameter nodes / animation graphs. A hotfix will be coming out soon.

In both 4.23 and 4.24 the plugin crashes my editor:

Here's how to replicate it:

• Create a macro library (for actors)
• Add a vector input to the macro you're creating
• Connect a "Break Vector"-node to the input
• Drag a line from one of the floats of the "Break Vector"-node and add any compatible node (such as float + float)
• Crash!

Hi, it looks like there was an update to the plugin (perhaps to fix the above bugs?), so I updated it. Now when I start a new C++ project in 4.24.2 and enable the plugin, I get an error on startup:

Plugin 'BlueprintAssist' failed to load because module 'BlueprintAssist' could not be loaded. There may be an operating system error or the module may not be properly set up.

This is on Win64. Can't start the project now unless I delete the plugin.

Sorry about the bugs everyone. Along with the hotfix for the recent crash, I added support for other graph types which included the Niagara graph and this caused the plugin to not load when you don't have Niagara enabled (why was niagara enabled on my build test project!?!).

While the update goes through, you can download the fixed version of the plugin here:

Edit: Hotfix 2.2.1 has been released, removing links

[fpwong]

Update 18 February 2020 (v2.2.0):

• The following settings have been changed:
  • Node padding and auto-formatting is now defined per graph type. For people who had auto-formatting disabled, you can search for "Formatter Settings" in the options and disable this per graph type
  • "Enabled graphs" has been removed and replaced with "Disabled graphs".
• Feature: Better hotkey & formatting support for Material Graph / SoundCues / AnimBP
• Bug fix: Crash related to parameter formatter (affected macros / blueprint graphs / anim bp)
• Bug fix: Formatting issue when creating a new node on the graph (commonly occured when using ReplaceNode command

---

Update 19 February 2020 (v2.2.1):

• Bug fix: Removed plugin requirement for Niagara

Also can someone double check if their settings will update to match the latest plugin version? I have changed the settings "Use Blueprint Formatting For These Graphs" and "Extra Root Node Types" but am unsure if default settings update when you update your plugin. See this image for the correct values: https://i.imgur.com/03I10j6.png

Thanks for the quick response! I downloaded the hotfix and it seems to be working great.

I have what's in your picture plus AnimationGraph and SoundCueGraph. Not sure if they are supposed to be there now.

I'm still getting a lot of crashes (around once every ten minutes). A selection of these lines appear in the log:

Not sure if that's helpful. I'm using 4.23.

[fpwong]

DasMatze Yes the settings should be as in the image. As for the crash, I believe this is occuring as you have the "Enable Faster Formatting" setting enabled. I'll pm you when this bug is fixed so you can re-enable this setting.
