FOSS gamedev and creative worlds

Any suggestions to make a floating wood node? Like if you threw a piece of wood on some water what would I need to do to make a subtype of wood that would always stay on the top of water. Like if the water level rose or fell it would follow the top of the water.

You mean like how we throw? Drop or place?

You can use WorldEdit to place floating nodes.

• Enable all WorldEdit mods (except GUI, you don't need it).
• Type //1 then //2 while staying at the same location.
• Type //set default:wood.

What I was thinking was making a new type of wood that you could place on water and if the water level rose, the wood node would always stay on top of the water. Like the way the boat behaves.

This is it what I had in mind but I'm hoping to expand it to a node type and not just an object.

You could simply take the "floating" code from the boats mod, and replace the boat model with whatever you want (a full block, some kind of log, etc).

Will is be all lua code?

Yes.

Cool, ill compare that with the floaty mod I linked to above and see if I can copy it to a wood node.

You could probably make a "floating" wood node that always moves up to the surface when under water. (and make it move any non water nodes above it upwards as well)

That would be funny.

:p

EDIT: Easy fountain in teh middle of teh ocean.

Well it would let us build huge floating ships that we could build stuff inside of. That's what I'm aiming towards.

I teased this out of the float mod, It uses a lua entity, that makes me think I can't apply it to a single node the way I'm thinking. In Minetest when we place two blocks beside each other they are seen as separate entities and unless we mark them as one entity they would all behave and float differently (I think). If you made a large wooden boat wouldn't it fall apart if the front hit water that was flowing in a different direction? Here's the code in case I'm wrong.

Boat?
Ohhhhhh this is getting interesting.
I actually at first thought this was actually rather dumb.

Also looking for this. Perhaps a simpler version that checks for water above a new type of buoyant block, and rises it until water is not above it anymore. I can't program but I've seen the mechanic in other mods such as vines and also the builtin falling.lua feature.

I have just recently gotten on board MineTest. I am 67 years old, retired drafting tech and ex-Norse recreationist, used to making things like armor, chainmail, kilns etc as I love to duplicate old tech. Years ago I built a clinker-built boat in the style of the Norse karfi... basically a small version of the dragon ship. I loved that thing and now that I have moved out of the desert to upstate NY I have lots of lakes and rivers which would have been great for building a bigger one. But I am now disabled with broken back parts and fibronyalgia. So it is I decided that building a dragonship in Minetest would be a fine project. I do a lot of time on the raft exploring my worlds in single player mode... I love the design and build aspects but have no interest in combat, engagement, monsters etc. I use it as a clunky CADD program. I am also a sculptor in ceramics/stone/wood/metals and want to be able to sculpt the wood in such a way as to create credible dragon heads for the prow of the boat, given the chunky nature of the blocks. So, with floating wood knitted together to form ship sides and sculpted heads/tails, we should be able to produce a decent ship.

Sculpting blocks? Not needed. You've got a 20 by 20 by 20 mile world - why not just build the ship on a gigantic scale?

in the "moving attached nodes" section of Vehicle Mods we list:

• airship
• Flyingships
• meshnode
• also take note of "technic' frames"

some of these should contain some ideas how to code a collection of attached nodes on water.
The biggest problem would probably be how to handle displacing water nodes.
When you would build some thing bigger that actually swims in the water and not only floats right on top, you would want to replace the water nodes that are under the waterline with nodes of your structure so that you might indeed be able to venture under deck. Once you move your structure the nodes behind you will of course have to turn to water again. So how will you manage that when your ship makes a nice smooth turn with all them in between angles? Sounds like some heavy calculating to me, at least for a voxel based game.

Based on the behavior of water I've seen before I'd think that the water would take care of itself. We'd have to use an abm to remove the water. The original mod I linked to the node just always positioned itself on the top of the water. Now that I think about it it would only work to make a flat bottom boat.

turning the ship would cause holes in the floor.

So we'd need deeper oceans and maybe an if block for collision detection with not water nodes?

Are you looking for something like walkable lily pads from MineClone 2?

For coders who are interested, here is the relevant code section:
http://repo.or.cz/MineClone/MineClone2. ... t.lua#l279

I'm pretty sure this can be turned to floating wooden planks or whatever with little modifications.

This now exists in the pontoons mod, but the whole featureset is not finished yet.

Floating wood node?

Sorry for off-topic, but "wood node" reminded me Mr. Woodnote and this.
