waterlily generation help

[bright stream]

how do I set my waterlily block to only survive on water that's not flowing?

"minecraft:placement_filter": {
    "conditions": [
        {
            "allowed_faces": ["up"],
            "block_filter": ["minecraft:water"]
        }
    ]
}

I'm using that script, but I would like the block to only spawn on the water that's still

spawn/survive

This is where you get into features and feature rules. You can find these files in a recent post https://discord.com/channels/523663022053392405/1324376503848275980 (go to bottom for the zip).

It is a big subject to tackle. I am just getting into it for an add-on I making and slowly making heads or tails of it. But these vanilla samples can help you learn how they do it. Some stuff is still hard-coded on their side tho, but I think, for the most part for what you want, you can figure it out.
