I need help with an Idea...

I want to make a blackjack application. I am trying to do it by creating all 13 cards, then having the event When button "deal" is clicked; 1 chances out of 13 at random: create object (I have 13 of these conditions, then for each respective condition, I have an action which is "create object" and one card of each 13). if this makes any sense. Could you help me make a blackjack game, and provide an example if you could? I hate to do this but I am stuck, I have beeen working on this for 2 months and haven't been able to find any help.

What area are you stuck with. Generating a random selection of the card to create?

Yeah.

I have found the easiest way to pick a random card is to:

Put all the card objects in an off screen zone then pick a random object from that zone. If I need 5 I run the event 5 times and move the picked card out of the zone.

Its a cheap way to do it but worked good for the couple card games I have made.

Well... Create the cards as a single active object, put the different cards in different directions...
THen use something like this to create the cards

* Condition to create a card
- Create active object card at x,y
- Card > Set alterable value a to random(13)
- Card > Set Direction to alterable value a

now you can easily check every cards value by using value a and the creation is done in a single event!

Heh, I always found it a little odd that one of the screenshots showing MMF2 shows a card game, but that game wasn't provided in the example files. Did that game ever really exist at all? ;)

Burfelt never got it 100% done :(

There is a card game in one of Jasons book or you can get some source files for card games at my personal website.
Link at bottom of my posts.

There is also the twister object that can generate number I believe. Most of the time you generate a randorm number in the range of 0 to 1.0. Then each card is assigned a range like 0.0 to .19, next might be .20 to .39 etc... based on the number of cards. Then generate a number and pick the card.

Jeff,

How do you move the picked card out of the zone?

The thing about generating random numbers for cards is you need to do checks for generating the same number too much... Like there isn't going to be 5 aces in a single deck.

One way to randomly select from a predetermined list is to literally make a list object and then random pick lines from it and remove those and store them somewhere else. That way the list is like the deck of cards. Once you remove a line from the list, it's like removing a card from the deck.

On my idea:

Add all the cards to a qualifier group

Use the condition to pick a random object in a zone (off screen)
Place all the cards to start with there.

Then under the qualifier you can set the position you want the card to go.

It will move the random object that was picked to that position.

I can dig up an example if you can't figure out what I do.

Personally, I'd do it Kondias' way, but I don't see why the other methods wouldn't work too.
The hard part is going to be working out whether you want an Ace to represent a 1 or 11 (eg. A+A+4+5 = 21), and splitting pairs.

Thanks for the reply Jeff. An example would be great if you have one.

Not to take anything from Jeff and this is an 4 year old post.

I have a "Random Card Example" on my website.

Eliyahu has since made a Deck of Cards extension which simplifies this greatly :)

Thanks for example Marv. For my clarification, once the card object is picked from the zone is the object removed from the zone? So the next time you pick a random object from that zone, the same object won't be chosen again?

I'm not working on a card game but trying to understand the concept of the pick random object from zone. Where is the object that was picked stored if I want to do something with the picked object later or destroy it?

You give all the objects in the zone the same qualifier, then you pick one particular qualifier object at random from within that zone, and move it somewhere else.

As Chris said is good. The cards are removed from the zone into another. They are still available to blow up if you want, or move them again.

Ehhh...board games seem to be easy but not....its VERY difficult........I'm trying to make a SUDOKU game and I'm stucked around 4 weeks...ChrisBurrows and Phi helped me A LOT...but I'm stucked in trying to check for duplicate numbers arrays in the same column, row or group.....

but I think that you case it's a little more easy..I dont know...maybe I'm wrong..

The quick and dirty way to do a sudoku style check would be to save each column/row/group's values in a string like so:

row1 = "2,3,1,x,5,6,8,9"
column1 = "1,2,3,4,5,6,7,8,9"
group1="x,x,4,5,2,9,8,5,1"

You'd just check to see what string doesn't have an "x", meaning it's a completed row/column/group and then check for doubles in that specific string. If no doubles, the string is okay. When all strings are full with no doubles, the game is done.

Wooow Konidias this is a good way....I'm working with string writting in a array....do you have a sample MFA file with your example to share to me? I understood but I don't know how to do this....

thank you very much!

Thanks for the clarification Marv. I still need clarification on my follow on question. How do I reference which object was picked?

Try setting a counter to the fixed value of the selected card.
