New feature request: auto farming

[end-user]

In the past, I've used a mod called "AutoHarvestMod". It attempts to do exactly what it sounds like - break all mature crops in reach, on the same level as your feet, as well as mushrooms & berries. It will also replant with whatever is in your hand. Additional functionality includes: shearing any sheep within reach, feeding any adult (breedable) animals that match the food you're holding, break grass (and optionally flowers) to get seeds. Is this something that could be added to "automation"? It includes a delay as some server detect too many packets coming in.

I also modified it to add a spawn-proofing function which is really helpful. Basically it looks for spawnable surfaces within reach (though not necessarily visible), and places something on it (button, slab, carpet, pressureplate, etc). This is tremendously useful because you don't have to see what you're doing. It also works while flying, so you can just fly around the nether and spawnproof those hard to reach places (like on the ceiling).

How hard would this be? Is there already code that can search in a small area around the player that could be leveraged?

There was script example for automatic wheat farming, but it is for cheatutils v2:
https://github.com/Zergatul/cheatutils/wiki/Script-Examples#automatic-wheat-farm-for-block-automation

It will require few adjustments for v3, since syntax was changed. If you need delay you can just add condition like this in the beginning:

if (game.getTicks() % 10 != 0) {
    return;
}

It can be possible to add ability to code automatic spawn proofing, I just need to expose method that returns light level for block coordinates.

And for entities interactions I think it is not currently possible.

[end-user]

Light level would be nice, but not strictly necessary. Might be useful to check for spots that are more than 1 block of air above though. I had trouble checking to see if I could/needed to place a block in cases where it wasn't air, but was spawnable (occupied by grass or flowers, for example), or wasn't full (I think soul sand is spawnable).

With regard to the farm example, can I just use something like player.useMainHand for breaking (for example to use a hoe) and player.useOffHand for planting?

[Zergatul]

There is no such methods. Block Automation gives you more high level methods. I rewrote script for v3:
https://github.com/Zergatul/cheatutils-examples/blob/master/v3/block-automation/01-wheat-farm.cs

[end-user]

Yeah, I think the scripting engine is great, really powerful and flexible. Would it be possible to expand to add methods to use items in the player's hands? Also, if you do add a light-level check, it would be possible to only plant on blocks that are light enough to grow.

[Zergatul]

I can probably add something like blockAutomation.useMainHand(); and blockAutomation.useOffHand();. From what I remember game will not allow you to place seeds if light level is not enough. In such places above script just sticks, sending packets to use item and server ignores them.

[end-user]

Yeah, that would be useful, because then I could use a tool with fortune to increase harvest (like carrots and potatoes), and have a stack in the offhand to replant. Plus, since you're example is checking for farmland, I could expand the example to check "if block is soul sand and player hand is nether wart" before planting. That would allow for lots of options: all the crops, nether wart, sugar cane, even bamboo. Could also check if block is a melon or pumpkin for breaking.

[Zergatul]

You already have void breakBlock(String itemId, String enchantmentId), so module can select a tool with fortune if you have multiple items.

[end-user]

Ok, this works pretty well. Can the breakBlock accept wildcards (like any type of axe or hoe)? Or for that matter, any type of item with "fortune" on it (since it doesn't matter)?

It would be nice to be able to simply "useOffHand" for planting - that way whatever the player is holding gets planted rather than having to modify the script based on what is getting farmed.

Also, is there a way to bind the blockAutomation to a toggle?

[Zergatul]

breakBlock doesn't accept wildcards. I can probably make it accept wildcard, since * or ? are not allowed in minecraft string ids.
I will add toggle for blockAutomation

[end-user]

well, another way to handle it is to use "tags", though I don't understand their support completely. For example, #axes under item tags matches all the types.

[Zergatul]

Added version 3.3.6, you can read changelog on curseforge
For spawn proofing you can use script like this:

if (game.blocks.getBlockLightLevel(x, y - 1, z) == 0) {
    if (game.blocks.canBeReplaced(x, y, z) && game.entities.canSpawnAt("minecraft:zombie", x, y, z)) {
        blockAutomation.useItem("moss_carpet", "from-top");
    }
}

Added tags property for Item and hasTag() method. Now blockAutomation can accept lambda function which checks ItemStacks from your inventory:

blockAutomation.breakBlock(stack => stack.item.hasTag("axes")); // breaks block with any axe

blockAutomation.useItem(stack => {
    return stack.item.id.endsWith("bricks"); // use any block that ends with b
}, "");
