Custom blocks connect with vanilla blocks

[dense tiger]

Is there a way to make custom blocks not connect to fences, glass panels, etc?

You can use vanilla block tags and typeIds to make the bones of you modle to connect with vanilla blocks

Which one? I don't want it to connect. For example, I have a custom block that isn't a complete block, but when you place it next to a glass panel, it connects, and I don't want that to happen.

he does not want fences to connect to his block.

Yeah, not possible currently.

Oh, my bad 😅, yeah, tough luck, man, that ain't happening. But if you really want to fix that, there's a workaround. You could make custom fences, glass panels, and iron/copper bars. Then, put a custom tag on them, like my_tag:unconnectable or something like that. After that, you could run a global script that checks if a block near the vanilla fence is a custom block with the unconnectable tag. If so, it replaces the vanilla fence (e.g., minecraft:oak_fence) with your custom oak_fence, in which you can specify whether to connect to your custom block or not. I mean it is a bit tedious, but that's the only way that I can come up with
