How do I analyze an array grid for 3 or more matching values

Can't be much more specific then the subject line lol. I'm trying to detect 3 or more matching values in an array grid, vertically and horizontally... then flagging the value of the x/y in the grid with -1 or something, so the entity corresponding to that point on the array can destroy itself, add points, and reset the position on the array/grid back to empty. If that makes sense... my brain hurts.

i have the same question, arrays are hard, i dont know if this will help you but this piece of code works perfectly to me:

With this code i can find 1 value in the array but i need to find another value in the array and if two values are matching then -> action (spawn enemies in this case)

i am reading this:

maybe the answer its here, maybe we need nested loops.. i am still reading

I think I might have the wrong idea of how loops work, as well as local variables. I wish the debug panel could should array values in a grid or something..

Yes, the debug panel helps you to check if the array is modified, but the next array tool helps me a lot to understand and handle the arrays:

I partially solved my problem with the array, check the part of the code that solves my problem, maybe can help you too:

Now i can find two values in the array and if are matching then spawn new enemies, but sometimes didn't work because sometimes just spawn 4 objects instead 5.

Sounds to me like you're looking for Match-3 mechanics. Rexrainbow has made an example using his own plugins. It's very flexible, but may not be too well suited for beginners.

I also made a little plugin using the jMatch3 lib. It is less flexible, but easier to use in my opinion.

Of course you can do this purely with events. I've done several Match-3 engines this way. Basically you just loop through a row/column (pretty much like Majinboo shows with the For-loop), have a variable hold the number of matches, which you get by comparing to the previous piece. If you reach a number of three are greater you have a match.

I can't seem to figure out how to pull a value from an array at a 2D position, like variable = (value x-3/y-5)

hahaha wow I suck

Can any of you see a bust in logic in this? I can't seem to figure out why this wont work...

Just thought I'd mention that you can do loopindex("loopheight") to get the value of a specific loop. That way you won't have to store those values in local variables.

Are the events in the loop actually cycling or is the engine duplicating the function with each having a progressing loopindex value - running at the same time - making counting cycles with a local variable pointless.
