Comparing Adjacent Arrays

Hello,

I have a grid of randomized objects I want to compare the adjacent arrays (North, south, west, east) to the selected tile so that I have an area of those objects

If you highlight that one tile (variable = highlight) it should compare CurValue (0,1,2,3 etc) and highlight it too

Why doesnt this work :S

First, you aren't checking your indicies for valid values (if curX = 0, then curX-1 is -1, not a valid index).

Second, you aren't picking the appropriate tile, you keep setting the value for the currently picked tile. You should set the selected tile's highlight outside of the For-loop and then pick-all to reset, then run the loop, picking the appropriate tile.

How are you referencing the tile to the array indicies?

I am not sure I get what you are trying to tell me, quite new arrays, but lets go.

1. So, I should stop the loop when it goes into negative values? I mean, if there is no Array there, it will just stop automatically or should I manually tell the loop to stop IF 0?

2. I almost figured that this kept happening and even if it checked the neighbouring tiles it would only change the value of the currently picked tile. How do I change the value of objects in an indice that is not even active? (still have to get my head arround these expressions). So I should highlight it -> pick all -> loop?

3.The Array has a randomized Instance Variable that selects the frame of the tile.

The key is the array has a UID to the Sprite, and the Sprite has the indices into the array, so that either can get to the other, depending on who needs to do what.

Thanks for the help, I am really greatful! but another problem arises, I have a completely random map with x colours.

And, if I select a tile, it should highlight all the tiles with the same frame/colour.

So if you hover over one of the five red it should highlight all of them, so comparing uid's doesnt do the trick here!

I uploaded a capx with just the problem to illustrate that.

Anyone? :/
