FOSS gamedev and creative worlds

I've noticed in minetest, water doesn't move items. How hard would it be to make water act similar to minecraft in how it will "uproot" certain plants (like wheat) and carry items that are on the ground.

I'm not overly fond of minecraft but it does have some nice little features like the water thing. Would be interesting if minetest had its own take on such feature. This would be useful in industrial style farming.

My personal suggestion is flowing water should move items in direction of flow and it should break things like say trees (maybe if water is 2-3 blocks deep and flowing), the various crops from farming mod, flowers from flower mod and so forth.

The big question is how hard would this "feature" be to do?

PilzAdam wrote a mod that does some of this. It moves items in flowing water, and makes lava destroy items.

My mod uses an hacky way to realise the item pushing by flowing water. It should be done in the core code.
Also the water destroying walkable and/or buildable_to nodes thing should be done in the core.
Both is absolutly possible. Would be nice if someone could provide a patch for this.

From this is just a little step to elevators.

Elevators are a bit easier than moving horizontally. Just have a look at the jumping-mod. With that, you can build elevators by removing the floor, let the player fall down on the trampoline, and "put" a pillow under the player at the desired height. Even items seem to come up again.

Okay, not elevator, more like gravity plating. To be pulled to predefined direction.

I think an ABM on flowing water can resolve the thing without core hacking.

Whats an ABM?

Active Block Modifier.

I think that it's more suitable add a way to edit core without hacking. For example, in the game folder (in default), it could be add some lua files that replaces builtin files if this files exist.

It exists.You can override core functions.
