Blender Game Logic Nodes (UPBGE-Compatible)

[Ratchet]

Are Set and Get object parmeters properties bugs fixed ?
Without those it’s not possible to make a game, because objects could not have variables

[Iza_Zed]

They were not really broken
I’m working with them every day, and I don’t have any issues with them

Check it out and if you have issues, let me know

[Ratchet]

That bug we discussed in the logic nodes bugs and request thread

@Iza_Zed

Ah ok, yeah that’s weird… to set a bool property, you need to check it and then un-check again, otherwise it doesn’t register the FALSE assignment, that’s why the error says “property_value = nothing ”, instead of nothing it should say False I need to fix this, thanks

( I would not use int compare each time i need to test if it’s true or false , bool is faster to use for all gameplay related things and gameplay states )

[Iza_Zed]

Ah yep that one I’m on, but the node is usable nonetheless, you just need to check the bool socket on the set property node and then re-uncheck it for the false flag to be intialized, I think that has to do with property handling

Hi @Iza_Zed
I want to try your node editor. I download source from:

GitHub - UPBGE/UPBGE-logicnodes: A Node-based Logic system for UPBGE 2.8+

But I can’t install the add-on (as source)

Can you please help? Thanks

[lordloki_reloaded (Jorge Bernal)]

this is possible my fault. I am going to check

[Daedalus_MDW]

the upbge eevee build i have comes with it bundled

[Skypatcher]

Really, I am using its own source folder.

[Iza_Zed]

That error is because I’m loading in custom icons, normally that should work, I do it the same way that the grove addon does it, which is officially supported

But as @Daedalus_MDW said, the current UPBGE_EEVEE build should have it bundled
Maybe try a build from yesterday or so?

[Skypatcher]

When I first install UpBge and open FPS_Template.blend. It open the adds-on installation dialog. But I can’t install it. If I exit the dialog, this is what FPS_Template.blend looks like. (You probably know what a broken node adds-on it would look like, :), here is the picture anyway).

I’ll try install new UpBge 0.3 alpha when you are ready.

[Iza_Zed]

Hmmm, it seems I can’t reproduce this, but try the following:

• Open your UPBGE folder, go to 2.83 -> scripts -> addons
• Remove the bge_netlogic folder there
• Download the latest Nodelogic Release from github, but on the releases page there (should be 0.8.8)
• Install and activate that

I tried with UPBGE from April 7th and from April 11th, both work for me lemme know if this works, otherwise just completely uninstall the Addon, then delete UPBGE, re-download the whole thing and try to activate the bundled version

I think it is related to this:

UI Previews will not be shown if you start a blender file previously saved in...

[Skypatcher]

i replaced bge_netlogic with Uchronian-Logic-UPBGE-Logic-Nodes-0.8.8-beta, same problem

[Iza_Zed]

Alright, I can remove the icons for now

[Iza_Zed]

Here, try this download again, it’s updated:

Release 0.8.8: UI Polishing, Node Completion and Compatibility + Rerouting ·...

It should now load in regular buttons if it can’t set the icons, hope it works

[Skypatcher]

I tried the “source code (zip)” directly, it gives me the same error.
Then I extracted “bge_netlogic.zip” as sources and copy to
2.83\scripts\addons\bge_netlogic
and it worked!

Now I can open FPS_Template.blend, the nodes are there.
But when I play the game, I can’t move or shoot. Here is the message in the System console:

@Skypatcher

ModuleNotFoundError: No module named ‘bgelogic’

the script has a typo it should be import bge or from bge import logic or bge.logic

@Skypatcher

Warning: mesh “Cube.004” has no vertices for material “MA”. It introduces performance decrease for empty render.

is a material error cube.004 has a material that is not assigned to a vertex/face/poly/etc. remove the material or use it to get rid of it.

I close UpBge0.3a and restart FPS_Template

It seems refer to a folder that I use in an earlier installation. Most add-ons has a “remove” or “uninstall” button. I suspect there is some cache.

Is there a way to uninstall this add-ons. I want to have a clean reinstall

[Iza_Zed]

Uhmmm, it’s rather hard to say what’s really going on without seeing your setup, but what you’d wanna do to have a clean reinstall is just to:
Remove your UPBGE install folder, open up your regular installed blender, check if you find the nodes addon (if so, remove it) and then redownload UPBGE and don’t install the addon, just activate the one shipped with UPBGE

I don’t think i have an import anywhere that says bgelogic, but I’ll check tomorrow

[Skypatcher]

I remove everything, re-download UPBGE from UPBGE-EEVEE experimental and extract it. When I run it, the following appears in System Console

The Game Engine Logic Nodes is already checked.
But when I unchecked it, I can’t enable it again. It has the following error:

After I replace the bge_netlogic with your new code, I can enable the add-on. But when I run FPS_Template, iI can’t move or shoot. The error is:

@Iza_Zed I will try again tomorrow, after you looked into the matter. Thanks
