Combining 2D Arrays?

[Davidobot]

How could one combine two 2D arrays?
For example this:

Code: Select all

map = {
	        { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
	        { 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 4, 1 },
	        { 1, 0, 1, 1, 0, 0, 0, 0, 1, 0, 0, 1, 0, 1 },
	        { 1, 0, 1, 1, 0, 0, 0, 0, 1, 0, 0, 1, 0, 1 },
	        { 1, 0, 0, 1, 0, 1, 1, 1, 1, 0, 0, 0, 0, 1 },
	        { 1, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1 },
	        { 1, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1 },
	        { 1, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1 },
	        { 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1 },
	        { 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 0, 1 },
	        { 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1 },
	        { 1, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1 },
	        { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
	    }

And this:

Code: Select all

map = {
	        { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
	        { 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 4, 1 },
	        { 1, 0, 1, 1, 0, 0, 0, 0, 1, 0, 0, 1, 0, 1 },
	        { 1, 0, 1, 1, 0, 0, 0, 0, 1, 0, 0, 1, 0, 1 },
	        { 1, 0, 0, 1, 0, 1, 1, 1, 1, 0, 0, 0, 0, 1 },
	        { 1, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1 },
	        { 1, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1 },
	        { 1, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1 },
	        { 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1 },
	        { 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 0, 1 },
	        { 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1 },
	        { 1, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1 },
	        { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
	    }

So that it becomes on table. Combining them next to each other.

Could you give an example of what you mean by "combining them next to each other"? I have a feeling if you read this thread it'll answer your question though.

*Edit: Might have misunderstood. Thought they were strings.

A 2d-array is a table of tables. So you should first try to figure out how to concatenate (combinate) two tables: Lets say you have

Code: Select all

a = {1,2,3}
b = {5,6,7}

Try to write a function that generates a table

Code: Select all

{1,2,3,4,5,6}

from this.

Once you have this function you can use it to concatenate 2d-arrays. If you want to have them side-by-side then you need a for loop which loops over the rows and for each row combines the two parts from the individual arrays. If you want to the two arrays on top of each other, then instead you do not need a loop but can directly combine the two (outer) tables.

[Ranguna259]

if what you want is what mich said then:

Code: Select all

a = {1,2,3}
b = {5,6,7}

Then this should do the trick:

Code: Select all

for i=1,#b do
table.insert(a,b[i])
end

I'll code a for loop for 2d arrays, just wait a few mins.

EDIT:
This should do the trick(it'll concatenate table a with b):

Code: Select all

a = {{1,2,3},
	 {8,9,10},
	 {14,15,16}}
b = {{5,6,7},
	 {11,12,13},
	 {17,18,19}}


for i=1,#b do
	 for ii=1, #b[i] do
		 table.insert(a[i],b[i][ii])
	 end
end
--debugger
for i=1,#a do
	 print(unpack(a[i]))
end

Test it out and post back

Are you trying to make the two 2D tables into a single 3D table or one single double-wide 2D table with table A on the left and table B on the right?

I was assuming the 3D one. (Where they are on top of each other. So basically the top-left cell for your new table would be the values of table 1 and 2. Basically x:1, y:1 would equal the values of cell 1, 1 from each, or {1, 1}.)

Yep that's what my for loop does.

EDIT:
Here's your unpacked table:

Code: Select all

1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1
1	0	0	0	0	0	0	0	1	0	0	0	4	1	1	0	0	0	0	0	0	0	1	0	0	0	4	1
1	0	1	1	0	0	0	0	1	0	0	1	0	1	1	0	1	1	0	0	0	0	1	0	0	1	0	1
1	0	1	1	0	0	0	0	1	0	0	1	0	1	1	0	1	1	0	0	0	0	1	0	0	1	0	1
1	0	0	1	0	1	1	1	1	0	0	0	0	1	1	0	0	1	0	1	1	1	1	0	0	0	0	1
1	0	0	1	0	0	0	0	1	0	0	0	0	1	1	0	0	1	0	0	0	0	1	0	0	0	0	1
1	0	0	1	0	0	0	0	1	0	0	0	0	1	1	0	0	1	0	0	0	0	1	0	0	0	0	1
1	0	0	1	0	0	0	0	1	0	0	0	0	1	1	0	0	1	0	0	0	0	1	0	0	0	0	1
1	0	0	1	0	0	0	0	0	0	0	0	0	1	1	0	0	1	0	0	0	0	0	0	0	0	0	1
1	0	0	0	0	0	0	0	1	1	1	1	0	1	1	0	0	0	0	0	0	0	1	1	1	1	0	1
1	0	0	0	0	0	0	0	1	0	0	0	0	1	1	0	0	0	0	0	0	0	1	0	0	0	0	1
1	2	0	0	0	0	0	0	0	0	0	0	0	1	1	2	0	0	0	0	0	0	0	0	0	0	0	1
1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1	1

(EDIT2:Huh.. there's a one missing)
(EDIT3:lol missed it when I was copying fixed )

And here's the code:

Code: Select all

mapa = {
           { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
           { 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 4, 1 },

           { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 },
       }
mapb = {

Thank you!
Works perfectly! Infinite worlds, here I come!

Thank you!
Works perfectly! Infinite worlds, here I come!

infinite well.. don't forget to optimize it so it will discard maps as you move forward or backward and reload them once you get close to them again because if you don't there'll be a massive impact on the performance

Now that is another problem, I will now need a remove function?!
