Mod Addition Request

[lubcubsgaming]

I know the main purpose of the mod is to spawn new falling blocks. But I can't seem to modify the BlockState of the block. I will walk you through what I am doing.

I have a mod that turns solid blocks into falling blocks. So I am doing a special ability where wherever you are standing. It launches that block up. So iI am hoping to do something in this order.

1: Turns solid block into falling block.

2: On the same tick, spawn your mods custom falling block with this command. /fallingblock moveFromBlockPosToBlockPosByTick ~ ~ ~ ~ ~ ~ true 30 minecraft:structure_block. (This spawns in a custom falling block that will launch about 3 blocks into the air and fall back down and turn back into a solid block right away)

3: On the next tick, data modify the BlockState of the custom falling block from the original falling block using this command. /data modify entity @n[type=commandfallingblock:better_falling_block] DataBlock.BlockState.Name set from entity @s BlockState.Name

4: Delete the original falling block

I am hoping for this method because I can't control how long it takes a vanilla falling block to turn back into a solid block and this is the only mod 1.21.1 that I have found that has some form of that.

Potential solutions for the mod to make something like this possible.

1: If running the command. Could we run it without a blockstate attached? And if there is a block at the start location. It turns that block into a falling block and deletes the block

2: Make it so the blockstate can be edited. This seems to be NBT controlled, but for some reason it can't be changed at all. Even when I spawn in a block that exists for 1000 ticks. And running data merges it doesn't want to update.

3: Add a command or NBT that lets us control vanilla falling block entities in a similar way, but adds a solidify time nbt?

Just some thoughts! Its a handy mod and appreciate you put the time into making it!

I don't understand why you need to modify NBT by data command. You can set blockstate like this:
/fallingblock moveFromBlockPosToBlockPosByTick ~ ~ ~ ~ ~ ~ true 30 minecraft:chest[facing=north]

Correct! I had given an example above for what I'm trying to do. I need to make it so any block can be affected. Not a specific block state. The command as is, requires a defined block state.

I want the player to stand on a block. They pick. Any block that exists in the game. And to be able to take the block below their feet and turn it into a falling block and give it motion to fly somewhere. Without doing a command for every block with property varation, that exists in the game. You know what I mean?

I understand now. If you are making your own mod, you can directly call these mothods in your mod:

add modrinth repository:

repositories {
    // Add repositories to retrieve artifacts from in here.
    // You should only use this when depending on other mods because
    // Loom adds the essential maven repositories to download Minecraft and libraries from automatically.
    // See https://docs.gradle.org/current/userguide/declaring_repositories.html
    // for more information about repositories.
    exclusiveContent {
        forRepository {
            maven {
                name = "Modrinth"
                url = "https://api.modrinth.com/maven"
            }
        }
        // forRepositories(fg.repository) // Only add this if you're using ForgeGradle, otherwise remove this line
        filter {
            includeGroup "maven.modrinth"
        }
    }
}

then add my mod as dependency:

modImplementation "maven.modrinth:commandfallingblock:1.21.1-fabric-1.12"

then you can import my mod's classes in your mod.
