[1.16.5] Multiple Advancement Start Points

[BloodshotPico]

I'm wondering if there is a way to have multiple start points on a single Advancement tab or if this is not possible? I believe I've seen it somewhere before however I'm not sure if that was via Minecraft version 1.12.2. I am using MC version 1.16.5 for this.

Basically the concept I'm trying to do is something like this:

• A1 goes to A2 > A3 > A4
• B1 goes to B2 > B3 > B4

However A and B don't link to each other at all.  (I have asked in other areas and I've been looking around but I'm just getting vanilla custom packs for advancements that from what I've seen don't have this.)

Thanks in advance,

~Blood

Yes-ish but also no-ish.

Basically you can only have one "root" advancement (consider it the advancement that unlocks the tab itself), but there are some things you can do to make that advancement invisible.

While I'm pretty sure the node graph is laid out programmatically now, you can still use Reflection to manipulate the placement (and so on) of the displayed UI (I did something similar in the past to create an achievement with two prerequisites that were themselves unrelated).

Old, old code, but you can see that I used reflection to grab the display column and row fields and then set them to specific values for some advancements (mostly vanilla ones to shove them aside for my own). The fakeIronBar advancement sits behind the vanilla iron bar advancement so it looks like there's two arrows pointing at the same thing, but in reality there's only one pre-req per icon.

I haven't quite messed around with reflection itself as much as other parts of Java right now, I'm still going through and learning what I can honestly. Reflection seems scary to the point I don't want to try it since I know I'll kill my ram or something silly.

However it is something I'm going to try learning after I learn more for now. However thanks for the input and letting me know.
