I'm trying to build a (Memory) game

I'm trying to get some information about how to create an applet with about seven squares on it and make the squares flash using a random sequence.
I've posted this before under a different topic but I didn't many responses... Please can anyone help me with this??

That's part of the problem...
I kinda need someone to help me structure this project and help me out alnong the way.
I know the first thing I want to do is
1. load approx. 7 or 8 squares or circles on the applet, but not the plain graphics, but an image of some sort
then
2. I want to do a random sequence of flashes in the images...
and
3. if the player repeates the sequence correctly, then the next sequence gets the number of flashes of the last level + 1. and so on...
4. if the player inputs an incorrect sequence then the game goes back one level
this is what I have so far...which is not much
import java.awt.*;
import java.applet.*;
import java.util.Random;
(variables here....)
public class game extends Applet implements actionListener {
  //setup the sequence array
  public void sequence() {
    int prev1= 0, prev2= 0, curr;
    for (int i= 0; i<image1; i++) {
      while (prev1 == (curr= rand(7) + 1) || prev2 == curr) ;
      prev2= prev1; prev1= seq= curr;
seqLength= minimumSeqLength;
// Random numbers
int rand(int siz) {
return Math.abs(rand.nextInt()) % siz;
this is supposedly how the sequence is going to happen but it does not work.
I really don't have the knowlege to get this game to do what I'm trying to ...
can you work with this???

  • Trying to build HTMLDOC

    Hi all
    I'm trying to build HTMLDOC as part of my larger attempt to install FOG which is a free ghost clone. I'm running into a make error 1 presumably related to the png configuration. But if it is the png conf, I'm not sure how to pinpoint what part is causing the error. Your help is kindly appreciated.

    First, I agree with Karol, use the AUR so that pacman can do its job.  Second, when you do your make, there is no reason to run it as root (until you do the make install)  For the initial build, it is much safer to not use root; plus all the files in your home directory will continue to belong to use, not to root.
    But, try the AUR.

    That being said I would try to disable the large amount of code.  Say you have a Main that launches a bunch of stuff, put a disabled diagram code around the launching part and then try to rebuild.  It is a very slow process (especially when the build takes a while to fail) but by doing this you can more isolate the parts of the code that can cause the crash.  The only time I've seen a crash on build like you described, I simply rebooted and it was fine.  Usually because of my own fault by stopping code in a bad way previously leaving things in memory.

  • Building complex flash game in Flash Builder 4 - Workflow/Best Practices

    I'm investigating switching to Flash Builder 4 for building a complex game that currently lives purely inside Flash CS4.  CS4 is a pretty terrible source code editor and debugger.  It's also quite unstable.  Many crashes caused by bad behavior in the SWF will take out the entire IDE so are almost impossible to debug.  And I've heard other horror stories.  To be clear, for this project I'm not interested in the Flex API, just the IDE.
    Surprisingly, it seems Flash Builder 4 isn't really set up for this type of development.  I was hoping for an "Import FLA" option that would import my Document Class, set it as the main entry point, and figure out where other assets live and construct a new project.  What is the best workflow for developing a project like this?
    What I tried:
    -Create a new Actionscript Project in the same directory where my CS4  lives
    -Set the primary source file to match the original project's source file and location
    -Set my main FLA as "export to SWC", and added "SWC PATH" to my flash builder 4 project.
    -Compile and run.. received many errors due to references to stage instance. I changed these to GetChildByName("stagename").  Instead, should I declare them as members of the main class?  (this would mimic what flash CS4 does).
    -My project already streams in several external SWF's.  I set these to "Export SWC" to get compile-time access to classes and varaibles. This works fine in cs4, the loaded SWF's behave as if they were in the native project.  Is the same recommended with FB4?
    -Should I also be setting the primary FLA as "export to swc"?  If not, how do I reference it from flex, and how does flex know which fla it should construct the main stage with?
    Problems:
    -I'm getting a crash inside a class that is compiled in one of the external SWF's (with SWC).  I cannot see source code for the stack inside this class at all.  I CAN see member variables of the class, so symbol information exists.  And I do see the stack with correct function names.  I even see local variables and function parameters in the watch window! But no source.  Is this a known bug, or "by design"? Is there a workaround?  The class is compiled into the main project, but I still cannot see source.  If FLEX doesn't support source level debugging of SWC's, then it's pretty useless to me.   The project cannot live as a single SWF.  It needs to be streaming and modular for performance and also work flow. I can see source just fine when debugging the exact same SWC/SWF through CS4.
    -What is the expected workflow with artists/designers working on the project?  Currently they just have access to all the latest source, and to test changes they run right through flash.  Will they be required to license Flash Builder as well so they can test changes?  Or should I be distributing the main "engine" as a SWF, and having it reference other SWF files that artists can work on?  They they compile their SWF in CS4, and to test the game, they can load the SWF I distribute.
    A whitepaper on this would be awesome, since I think a lot of folks are trying to go this direction.  I spent a long time searching the web and there is quite a bit of confusion on this issue, and various hacks/tricks to make things work.  Most of the information is stale from old releases (AS2!).
    If a clean workflow I would happily adopt Flash Builder 4 as the new development tool for all the programmers.  It's a really impressive IDE with solid performance, functional intellisense, a rich and configurable interface, a responsive debugger..I could go on and on.  One request is shipping with "visual studio keyboard layout" for us C++ nerds.
    Thanks very much for reading this novel!

    Flash builder debugging is a go!  Boy, I feel a bit stupid, you nailed the problem Jason - I didn't have "Permit Debugging set".  I didn't catch it because debugging worked fine in CS4 because, well, CS4 doesn't obey this flag, even for externally loaded SWF files (I think as long as it has direct access to the SWC). Ugh.
    I can now run my entire, multi SWF, complex project through FB with minimal changes.  One question I do have:
    In order to instantiate stage instances and call the constructor of the document class, I currently load the SWF file with LoaderContext.  I'm not even exporting an SWC for the main FLA (though I may, to get better intellisense).  Is this the correct way of doing it?  Or should I be using , or some other method to pull it into flex?  They seem to do the same thing.
    The one awful part about this workflow is that since almost all of my code is currently tied to symbols, and lives in the SWF, any change i make to code must first be recompiled in CS4, then I have to switch back to FB.  I'm going to over time restructure the whole code base to remove the dependency of having library symbols derive from my own custom classes.  It's just a terrible work flow for both programmers and artists alike.  CS5 will make this better, but still not great.  Having a clean code base and abstracted away assets that hold no dependencies on the code  seems like the way to go with flash.  Realistically, in a complex project, artists/designers don't know how to correctly set up symbols to drive from classes anyway, it must be done by a programmer.  This will allow for tighter error checking and less guess work.  Any thoughts on this?
    Would love to beta test CS5 FYI seeing as it solves some of these issues.

    How are you launching the debug session from Flash Builder? Which SWF are you pointing to?
    Here's what I did:
    1) I imported your project (File > Import > General > Existing project...)
    2) Create a launch configuration (Run > Debug Configuration) as a Web Application pointing to the FlexSwcBug project
    3) In the launch config, under "URL or path to launch" I unchecked "use default" and selected the SWF you built (I assume from Flash Pro C:\Users\labuser\Documents\FLAs\FlexSwcBug\FlexSwcBugCopy\src\AdobeBugExample_M ain.swf)
    4) Running that SWF, I get a warning "SWF Not Compiled for Debugging"
    5) No problem here. I opened Flash Professional to re-publish the SWF with "Permit debugging" on
    6) Back In Flash Builder, I re-ran my launch configuration and I hit the breakpoint just fine
    It's possible that you launched the wrong SWF here. It looks like you setup DocumentClass as a runnable application. This creates a DocumentClass.swf in the bin-debug folder and by default, that's what Flash Builder will create a run config for. That's not the SWF you want.
    In AdobeBugExample_Main.swc, I don't see where classCrashExternal is defined. I see that classCrashMainExample is the class and symbol name for the blue pentagon. Flash Builder reads the SWC fine for me. I'm able to get code hinting for both classes in the SWC.

  • Captivate 7 Memory Game Failure

    I am using Captivate 7.  Everything in my presentation is working fine except for the Memory Game interaction.  I've created the slide for the Memory Game and it works perfectly when I preview it in Captivate.  However, when I publish, that particular slide is blank (Memory Game only).  Everything else on the slide is OK.  What is happening so that the Memory Game does not show up?

    Have you set up the publish folder location as a trusted location in Flash Global Security settings?

  • Memory Game Widget

    I'm creating a memory game to help our leanrers prepare for their written driver's test.  Ideally I would like to see them match the road signs with the correct words (I've made PNG files to house the text for each card), but from what I can see we only have the option to match exact pictures.  Is there a way to set it up so that you can have a group of pictures to match againts their counterparts, which would be a different picture?
    I could use the drag/drop tool to achieve something similar in concept of matching, but I like the idea of having a memory game for the added fun. 

    Hi Lilybiri - thanks for the welcome!
    Actually, I was trying to use the new widget in the Captivate 7.  It is something like this one, but I want to match 2 different pictures technically.  For example:  Picture 1: street sign of railway crossing ahead ---- MATCH TO ---- Picture 2: (image of) text says "Railway Crossing Ahead".  That way they have to match a picture to the correct text.  Does that make more sense?  I'm hoping that I can still use the widget, but with more customizable options.

  • I am trying to get into my Game Center app but every time I tap on the app it opens too a blank white screen. I have tried several times to reset my phone but I get the same result.

    I am trying to get into my Game Center app but every time I tap on the app it opens too a blank white screen. I have tried several times to reset my phone but I get the same result.

    Hello there Sweebs44,
    It sounds like you are tapping the Game Center app to open it, but the screen is blank. I recommend signing out of your account:
    Go to Settings > Game Center, where you can:
    Sign out (tap your Apple ID)
    From: iPhone User Guide
              http://help.apple.com/iphone/7/#/iph6c493cac
    Then close all the running apps:
    iOS: Force an app to close
    http://support.apple.com/kb/ht5137
    Double-click the Home button.
    Swipe left or right until you have located the app you wish to close.
    Swipe the app up to close it.
    When you have done that restart the phone sign back into your account and try again:

    Thank you for using Apple Support Communities.

  • I am trying to build a basic TCL skeleton script that reads a remote SNMP OID and displays the value on the screen.

    I am trying to build a basic TCL skeleton script that reads a remote SNMP OID and displays the value on the screen.
    I don't want it to be an EEM Event, I just want to run it from the (tcl)# prompt.
    So I guess I'm asking if you can use cli_exec and other commands in the "namespace import ::cisco::eem::*" in a normal non-EEM script - can I do that?
    This is the error I get:
    OTN.159(tcl)#source flash:TCL_SNMP_Remote_Read.tcl
    invalid command name "::cisco::eem::event_register_none"             ^
    % Invalid input detected at '^' marker.
    What am I missing?
    =================  TCL_SNMP_Remote_Read.tcl  ==============================
    ::cisco::eem::event_register_none
    namespace import ::cisco::eem::*
    namespace import ::cisco::lib::*
    if [catch {cli_open} RESULT]
        { error $RESULT $errorInfo }
        else { array set cli1 $RESULT }
    if [catch {cli_exec $cli1(fd) "snmp get v2c 192.168.1.100 public timeout 1 oid 1.3.6.1.2.1.1.1.0" } RESULT]
           { error $RESULT $errorInfo  }
           else { set SnmpSysDesc $RESULT }
    if [catch {cli_close $cli1(fd) $cli1(tty_id)} RESULT] {
                error $RESULT $errorInfo
    puts $SnmpSysDesc
    =========================================================================
    In the sho-run config I have:
    event manager directory user policy "flash:/"
    event manager session cli username "cisco"
    Any help to get me started would be greatly appreciated!

    If you don't want an EEM policy, then don't use any of the EEM constructs.  Instead, all you need is this:
    set output [exec "snmp get v2c 192.168.1.100 public timeout 1 oid 1.3.6.1.2.1.1.1.0"]puts $output

  • Why when I am trying to install a free game app does Apple need my credit card info?

    I am trying to install a free game app and it won't install without my credit card info.  Why?

    To verify that you are who you claim to be in the country where you claim to
    be so you can use that country's AppStore. Also because many free apps have in-app
    purchases.

    The Game Center used to work with my Apple ID before I updated to iOS 7.4, I used to play multiple player with EA Real Racing 3 game but it doesn't work at all and every time I tried to go to the Game Center it's just blank, even to the settings nothing!

    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Go to Settings>Game Center and sign out and sign back in
    - Reset all settings      
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup. See:                                                
    iOS: How to back up                                                                                     
    - Restore to factory settings/new iOS device.             

  • Is it possible to pass the score of the memory game as a variable using javascript?

    Hi,
    I would like to create a score table for the memory game. For that I need captivate to pass the last sore to a form/page. In the memory game widget there is a variable displayed: memGame_var. Is this really the memory game score, and do you think that I can achieve my goal using javascript?
    thank you!
    Heloisa

    Beware: you have to create a variable, it is not automatically created. And you don't have to use the same name, but in this case for some reason it is not possible to use capitals in the variable name.
    Contrary to some other games, this variable will retain the score indeed.
