Trouble with vectors and arrays.

Krieger

Hello. Just recently I've taken a look into 2D arrays and vectors and so far, it's been one of the hardest topics. If you could leave an example or some hints or even a tutorial into the subject, it would be most helpful. Thanks for the attention, Krieger.

Here is a tutorial on arrays I wrote: http://staticvoidgames.com/tutorials/basicConcepts/arrays

What exactly about them are you confused about? Can you post an MCVE demonstrating exactly what you're talking about?

it's actually not really hard.

A 2D arrays is like a chess board. A grid.

You need two numbers to say which field / cell you mean.

In this cell is a value (number, String, image).

That's it.

grid [x][y] = "Hello";
