GameObjects in multidimensional Arrays

Questions & Answers
1

guys i need your help, it seems some alien lifeform has pulled the simplest coding skills from my brain:

when i do the following as a declaration:

public int sizeA = 10;
public int sizeB = 15;
private GameObject[][] objects;

the compiler wont let me do this in my start() ;

objects = new GameObject[sizeA][sizeB];

i get an error: Assets/Scripts/CubePlane.cs(25,40): error CS0178: Invalid rank specifier: expected ,' or ]’

i guess i miss the forest, standing in front of all the trees here, what do i do wrong ?

thx in advance guys

That’s because you’re using [jagged arrays][1], which are supposed to be initialized like so:

objects = new GameObject[sizeA];
for (int i = 0; i < sizseA; ++i)
    objects *= new GameObject[sizeB];*

You’re probably better off using [multi-dimensional arrays][2]:
private GameObject[,] objects;
objects = new GameObject[sizseA,sizeB];

ok i think i found the answer for myself: i used a so called “jagged array” ; which is GameObject and you cant, for whatever reason, initialize the way i did

… however … when using a true multidimensional array, corresponding to c# syntax you can do the following:

private GameObject[,] objects;

objects = new GameObjects[sizeA,SizeB];

that works fine…

Here is the C# documentation for arrays, could be useful for you. https://msdn.microsoft.com/en-us/library/aa287601(v=vs.71).aspx
