Making a cube around a location. [Help]

Hello, I am having some trouble getting through the thought pattern of doing this... I know it requires three loops, one for x, one for y, and one for z; however, I struggle with what exactly I would put within the loop parameters... Any help is greatly appreciated! Thanks!

 

theres 2 ways you can do this. 1) single point, define length width, height, create loops and build. or 2) start point, end point, create loops and build.

pseudo (means translate from english)
width = x2 - x1
length = z2 - z1
height = y2 - y1
for Y start through height
for Z start through length
for X start through width
replaceblock(world, x, y, z)
end
end
end

if you do dual coordinates, you have to translate the coordinates to LowXYZ and HighXYZ containing the lowest X coord vs highest. If you do by length-width-height, you can just subtract the center point by the said vars etc.

 

Komak57 Thanks I think I got it
