so i know how to make perfect circles and a cylinder is not that hard, but im not so sure how to make a perfect cone. I know in geometry they told me the volume was 1/3 of the volume of a cylinder with same base and height but i dont think that'd work in minecraft. so please any help?

Make the cone so big, that if you look a bit far away, it looks almost rounded, but it would kinda be impossible, because the sky limit in this game won't allow you, but other then that, creating a cone in the game is impossible without having some sort of mod or just turning that cone into a triangle.

The hard way: Start with a circular base, then make triangle's from the edges of the circle whose altitudes intersect a perpendicular line from the center all the way around the circle.

Make a big circle on layer 1 (whatever your ground layer is). Move one layer higher, and decrease the diameter of the circle by one. Continue until you have a cone.

Hope that helps.

The only thing worse than Creepers? Zombie Creepers. After exploding, they come back from the dead to explode again. And again. And again.

to clarify on this guy and the next guy, you should actually decrease the radius of the circle(s) by one, not the diameter
also, for clarification, this viewtopic.php?f=35&t=28896
using this, make a circular base of whatever diameter you wish

so heres the base from a side view, I don't want it to look like a pyramid from some angles which the guy I had quoted had possibly unintentionally implied, not to forum scale

heres the next thing that i would do using '9 circles' as shown in the provided picture, also not to forum scale

then I do the next thing with two '8 circles', and smaller circles, and smaller circles all the way until I get down to 1 circles, at which point I would need a high resolution picture in .png format that had a diagram of circles all the way down to a single pixel for a circle

I'd like somebody to provide that picture

its because the real thrill of minecraft is the first night. its like dating. nobody likes the relationship 2 years in.

thnx for the feedback i think ill go with the making a circle and making it go smaller idea but i think that makes domes? If it does than ill make two congruent perpindicular triangles the have the same poit and then try and make a curved base

Making each layer have a diameter 2 smaller DOES make a cone. If you want to make a dome you need to make the size of the circles follow the curve of a circle vertically perpendicular to the base circle.

http://hardijzer.nl/MinecraftCone.html maybe.. but it seems to support only even diameters, which is kind of useless since I build always odd structures :tongue.gif:

Newest worldedit (from build 459 onwards) in http://build.sk89q.com/job/WorldEdit/ has //generate command... you can generate all kinds of stuff (like DNA) with it. Formulas for cones:

Standing on base: x^2+z^2
on tip: x^2+z^2

etc. you can do cone-shaped holes to ground and other stuff with it. Works like //generate [material] [formula]

Sorry for the necro, but we've been trying to make a Christmas tree using the CONE function you posted above.

We've decided that once we have a solid tall thin cone of pine logs, we can make a slightly larger cone around it made of leaves. That said, we are having no luck using the formula above.

Here's what we've tried:

I tried manually entering integers for x, y, z and got no result. We've tried selecting a cuboid of x, y, z dimensions and then entering the //generate code as above. I then tried it without entering any inputs at all for the dimensions, thinking it would draw an "isosceles" cone on the ground where I stood. But nothing happened.

We've tried both of the above methods using the flags -h for hollow, -r for raw debug coordinates, or no flags at all. Nothing worked!

I've looked at the formula and checked it against the expression syntax for JRE 6's Math methods, and it seems accurate.

Help? We're aiming for an outer cone (leaf layer) of about r=7 and h=24. The inner log cone should be r=5 and h=20 or thereabouts so the leaves are adequately supported.

Heh seems it was changed so that Worldedit gets values from the selection, so it's not neccessary to input them into the expression anymore... I'm pretty sure values in x,y&z were required when I used //generate function last time, of course I may remember wrong

So now it is neccessary to only select the proper area with wand and then type //g -h 1 x^2+z^2

(-h makes it hollow instead of solid)

I don't know the easy way.
