Anyone want to test my Portals addon?

klaas

Hello there! I've spend the last weeks writing a portals plugin. Dont mix it up with the game. This is a technique for culling occluded geometry.

If you dont know it you can read about it here: https://en.wikipedia.org/wiki/Portal_rendering

There was a implementation in Godot 2.x but it was removed in 3.x

I've tried my very best to make it as handy as possible. But i need feedback before i try to publish it in the assetLib.

You can get it here: https://github.com/D2klaas/dzPortals

I would like to here from you ... comments, suggestions and issues.

all the best! Klaas

I downloaded the project & copied the addons folder to an empty project. Godot says there's a problem with the code:

"Unable to load addon script from path: 'res://addons/dzPortals/dzPortalsPlugin.gd' There seems to be an error in the code, please check the syntax."

I checked "dzPortalsPlugin.gd", the error is on line 18, with the preload function:

"res://addons/dzPortals/dzPortalsPlugin.gd:18 - Parse Error: Couldn't fully preload the script, possible cyclic reference or compilation error. Use "load()" instead if a cyclic reference is intended"

Hi, thank you for your feedback. I've found the error, amd fixed it. But i stumbled into another bug. Currently godot crashes when a tree node is moved and autoconnect is on.

In totaly confused about that. Must have another closer look into it. Its pretty useless by now.

I updated the repro to the current state ... wil dive into it tomorrow.

Thanks!

Very Impressive work! I tip my hat to you good sir. ?? In fact, I'd love to contribute to the growth of this plugin. I have quite a bit of experience with plugin interfaces.

Hi SIsilicon28, thank you. I would appreciate your help!

Im currently facing that bug that crashes godot whenever i reorder the tree. I could track the error down to: addons\dzPortals\scripts\dzPortalsGate.gd

in function: auto_find_magnetic_gate()

in line 329, 330 there call set_magnetic_gate(gate) and this causes the crash when the node gets moved.

Maybe its because the node leaves the tree for a short moment. All tries to deferre this call failed. Without any error description im totaly lost.

Hello, after spending a whole day its finaly fixed. It was ... whar a shame .. two simple cyclic assignments. The usual case in wich godot crashes. I wish godot would have a call stack limit in debug mode. This would have thrown an error a prevent the crash.

... and there is a new feature. Zones can now be flagged as "outside". Those zones will be activated when the camera is in no other zones. Its like a default zone. Those outside-zones can be linked to gates. So, if you look through a portal to the outside it gets visible.

The repro is now updated.
