Logic Toolkit

I tried to reproduce the problem but was unable to do so.
This may be a problem that is easily affected by the timing of ComputeNode execution.

For now, I will take the following measures.

Open Packages/com.caitsithware.logictoolkit/Editor/Graph/Dataflow/NodeEditors/ComputeNodeEditor.cs in a code editor
Insert the following code at the beginning of the ComputeNodeBaseEditor class
Code: Select all
```
private bool _IsAttached = false;
```
Insert the following code at the beginning of the OnAttachToPanel method
Code: Select all
```
_IsAttached = true;
```
Insert the following code at the beginning of the OnDetachFromPanel method
Code: Select all
```
_IsAttached = false;
```
Insert the following code at the beginning of the OnPlayModeStateChanged method
Code: Select all
```
if (!_IsAttached) return;
```
Insert the following code at the beginning of the OnComputed method
Code: Select all
```
if (!_IsAttached) return;
```

Thank you!
Yeah I also couldn't find the way to consistently reproduce it, but I will try the method you mentioned if it happens again.

Thank you for your report.

Based on the log contents, it seems that this occurs when object destruction and ComputeNode processing occur at the same time.
We will confirm the reproducibility and fix it.

If this error starts to occur, the temporary solution is as follows.

Open any script
Insert a blank line or something and save
Wait for compilation and domain reload to complete

This should also unregister the invalid callback.

Hello,

Logic Toolkit: 1.9.0
Unity: 6000.1.2f1

Once in a while this error keeps showing up in the Unity editor while I am testing the logic toolkit logic.
The only way to stop it is to restart Unity editor, closing the logic editor or opening a different scene doesn't fix it.

Any idea why and how it can be fixed?
