Cement Physics: Anybody know a good video?

[RaustBlackDragon]

I've read the wiki on how they work, but since it's made out of precious soul urns, and since any mistakes are extremely tricky to remedy owing to the scale of the stuff, I was wondering if anybody had a good instructional video that explained in detail how cement behaves with its spreading mechanics?

This.

[Husbag3]

I think it flows for 14 blocks but I can't be sure.

[The great randomo]

16 blocks in each direction.

[RaustBlackDragon]

16 blocks in each direction.

Including downwards?

[The great randomo]

Yup.
I think it's 16 blocks...

[Husbag3]

I don't think there would be a limit going down, there isn't for lava or water.

[Battosay]

Yes, there is.

[RaustBlackDragon]

Yes, there is.

OOOOH. Damn, then it's not gonna help with what I have in mind :(

If there were some sort of corrosive acid that had those mechanics, that'd be another thing, but...

Anyway, thanks for clarifying guys :)

For me creative mode doesn't exist. It take the fun out of figuring stuff out.

Fix'd :)
I generally play around with any given feature in creative first, to get a feel for it. Well, not creative, but TMI. :)

What did you have in mind?

It seems to pick which directions to expand in in the same way as water, but only go for 16 blocks. Is that not going to work?

Also, if you supply redstone power to the source block it won't set, so you might be able to experiment some with just one bucket. The easiest way is probably a solid block above the source with a lever. Be careful though, if you cut off the flow by placing blocks then that part will set rather than vanishing.

I wanted a quick way to create a large hollow area which I could make pitch black to turn into an arena to fight monsters in.

[Itamarcu]

So can't you use Mining Charges?

Clever "fix." It's still a huge "no" for me though. The cost is part of playing the game to me.

Of course I had a week-long debate with myself over whether Rei's Minimap was cheating for me.

Same for me. I regret having even used creative for testing mod features as I was developing them (namely the Lens).

To make buildings with cement, it seems you need to build a flat ceiling yourself, and then pour a bucket of cement in the middle to get walls. It sounds like a single pour might not be as large as you want.

This is actually really impressive. I figured you'd have to have some sort of test world for testing new features.

I've had to put off building some new things as I've had to go back to mining because I'm completely out of diamonds. I just found three and was thrilled! I still need a bunch more as I want to delve into some of the more advanced features of BTB.

Nah, what I usually do is create a backup of my save when I'm about to test something new and "high risk", then just keep playing/testing as normal. If something really blows up on me (and that has happened very rarely), or I decide to drastically rebalance the recipes or something, I can revert the save if need be, but the vast majority of time, I just keep going from there.

I found it very effective to build trenches at roof height, pour in the cement (power the source block). Let the cement first spread on the upper Layer and then remove the bottom of the moulding. It now flows down to create walls. Note however, that the walls become shorter the further away form the source they are. Let it all set and your wall is done.
It is also advisable to build a dam at the bottom of your "construction site" to avoid mishapps involving cement spreading all over the place.

Roof pouring involves as much work, as building the roof manually in the first place. I wouldn't recommend it.

Unless something has darastically changed this is incorrect. Cement will spread in all horizontal directions unlike water which chooses the laziest path to the next block down.

Raust, cement is still very much a viable option for your "under-dome", but for it to be used effectively you'll have to design around cements limitations which is that it cannot flow diagonally. If you want to test out how cement flows and not feel like you've wasted a soul urn you could use it to fill in some unwanted body of water and watch it as it spreads out and downward.

Thanks, my explanation was completely wrong about which directions it chooses to spread,
and probably made it sound much harder to work with.

What I meant to explain was that most blocks spread to the sides if there's a solid block beneath,
otherwise just straight down, and the source block spreads to all sides and down (if possible).

If you want to test out how cement flows and not feel like you've wasted a soul urn you could use it to fill in some unwanted body of water and watch it as it spreads out and downward.

As long as it's a shallow pond - I hoped you might mean cement spreads also into a wider plume in water, but it just goes straight down in the ocean:

Lol sadly no it doesn't work like that :pguess I should have specified starting at the shore line.
