So I was trying to make a block in Minecraft that, when activated (right or left click), would expand into a building. I had been doing it so far with a ton of trial and error as I couldn't think of a better way. While thinking about it the other night, I thought it would be possible to set up an array and use for loops to get the values stored 1 at a time. The thing is, I have no earthly idea how I would do that. There would probably be a lot of arrays, but far easier in the end. I know how to display the blocks, and I just would have to change 1 value to be the arrays value. Does anyone know how I could get a for loop to get me values from an array?

I thought for sure you were smart enough to realize I always look into those sort of things before I make topics or posts... I guess I need to think of you as the attempted helpful "troll" pointing out the obviouse. :p Now enough picking on you and make a real reply.:p
I seem to always do better to see an example instead of their "argument" listings and links to the other objects used and needing to go all over the place for 1 thing, not the 50 I would have to go through and still be lost.

Why would you need a lot of arrays instead of one array? If you actually would, why not use a single 2D array instead of a lot of 1D arrays? To use a for loop you would just, you know, use a for loop over the array; I'm not sure I understand your question.

I am making a 3D object that isn't a perfect cube, it has a hollow inside at places, a single array is far from what I need.

Sounds like a single 3D array is exactly what you need.

Here's an example where I create a 100x100x100 integer array, fill it with some multiplication, and then print it out:

Code:

That wasn't clear at all from your first post. Depending on what percentage of it is filled, you either want a three-dimensional dense array, or a single sparse array of three-tuples.

Edit: To clarify, lest it seem I was ignoring Merth's well-thought-out post, I was introducing the alternative of sparse arrays.

Well after a ton of research (I never have really used an array, much less a 2D array(also forgetting that an array is more of a list, while a matrix is like a 2D array)) and finding out how to store to it, I found it, then I see Merth's post, it is close to what I needed, downside is I need 2D because each layer isn't the same size, but I will be back if I start having issues.

One more quick question, is there an easy way to store objects to a oh.. 30x30 2D array like
array1[30][30]
and not have to store each value one by one, maybe a way to store values to it in a loop but not necessarily using one value?

I can post an example array later when I can get one of them made.

Well I have figured out 90% of my issue, I can set array's up manually when I create it, but I cannot get it to work by setting it up like:


Code:


I would love to make creating those shorter, but I can't figure out why I cannot assign anything to it...

How are you trying to assign to it? You could just do floor[x][y] = whatever;.

I am trying to use for loops to store a value, such as:


Code:


To store values to the array 1 value at a time.

Code:
