Button index?

[Keli]

I have a button object. I used duplicate and have 10 columns and 10 rows.
This button seems to be an array as I use at start of frame:
Set Alterable Value A Random(10)+1
Change Text to Str$(Alterable Value A( "Button" ))
This gives my a 100 buttons with a lot of different numbers. I use this for a simple Math game.

The grid could be like this:

1 2 3 4 6 5 6 5 4 3
5 6 7 5 4 9 8 7 4 3
9 8 9 8 9 2 3 4 5 2
4 5 6 7 5 1 3 4 5 6
1 2 3 4 6 5 6 5 4 3
5 6 7 5 4 9 8 7 4 3
9 8 9 8 9 2 3 4 5 2
4 5 6 7 5 1 3 4 5 6
1 2 3 4 6 5 6 5 4 3
5 6 7 5 4 9 8 7 4 3

Then a sum appears in a text box and you click on a button(s) and get the right sum. If the sum is 4 then you could click on 1 and 3! Those two buttons then disappear. ( This idea is not mine) I´m just trying to implement this using MMF2.

Now I want to add an extra bit - if all the numbers in a row or column are cleared then you get a bonus. In Visual Basic I would use index of the button array. Which is the best way of addressing an individual button?

You would Spread Value 0 in an Alterable Value of the buttons, so each has a unique ID. Then you can loop through them in a fast loop. On loop AND Alterable Value of Button = Loop Index AND whatever other conditions.

However, someone will come on here and say use the ForEach object. I guess try out ForEach, it might be able to do what you want.

Well, seeing as the ForEach object is exponentially faster than the other method, and that it can support looping through buttons, I think it would definitely be the better option.

Hi

Thanks both for your good help. Do you know of any examples?

Examples come with the For Each object...

[Eliyahu]

ForEach is also buggy and unreliable.

It is? I didn't know that. Can you explain what and how it is buggy. I would appreciate it.

Thanks

I had problem putting it into my games because it runs the ForEach action last, so you cannot do it mid-event. After finally getting it to work in EXE, it ended up being SLOWER than if I had done it with alterable values and fast loops. I kept the ForEach loop there, it was all working, and I exported to flash, and my whole game just was a mess. Actives were spawning randomly, nothing was working, I couldn't even identify what was wrong because of how messed it was.

Overall I've had terrible experiences with ForEach every time I've used it, about 3 times. I will not be using it again.

Oh, ok and thanks Eliyahu.

Hi Keli,

I've added an example mfa file in thefile archive for your reference, hopefully it will help you!

It works out once a full row of boxes has been destroyed.
Any problems let me know.

I just realised you wanted columns AND rows! You can use the same principal for columns also, I'm sure you can figure it out

Have fun!
