ActionScript 3 - Player enemy collide, decrease of health bar

• Make the health bar down (AS2)

  Well, after some work and a lot of mistakes, so I made a health bar for my game. (It is the Actionscript 2)
  
  Basically, the code is the file .as my main character, there is
  var maxHealth: number = 100;
  health of the var: number = 100;
  
  and further down the line...
  _root.healthBar._width = (health/maxHealth) * 200;
  
  ~~~~~~~~
  
  So, when I change the number of health lower var, the health bar drops lower. Sweet! It works!
  
  Now, just wondering if any of you guys could help me code so an enemy can inflict damage on the main character.
  I have tried several codes, but they all failed.
  
  If (this.hitTest (_root. Monster))
  {
  
  }
  
  That would put the parentheses?
  
  Thank you

  :

  If (this.hitTest (_root. Monster))
  {
  This.Health-= 10;  for 10 damage

  and always make sure that health does not go below 0 and when it reaches 0, you take action
  }

• Try to make the health bar

  I'm doing a health bar. I'm trying to make sure when your health goes down, the bar moves.

  
  Health = 100;

  HealthBar.TheBar._xscale = the health;

  function updateHealthBar() {}
  HealthBar.TheBar._xscale = the health;
  }

  So far, this is what he does. I made a button, and when you press it it takes your health 5.

  How can I do one side move to the left instead of them, both moving to the Middle?

  Position the wicker and its alignment is along its left edge.

• Decreases in health battery optimized performance

  I have this problem where when I choose this option, the game performance decreases significantly. I have a y510p with a geforce sli dual 755 m. The second graphics card goes off when it is not plugged in, I'm guessing that the case is at the moment. I rebooted my computer with restart of the entire application and it was not fixed. What I have to reduce my battery less than 60%, then plug it in then get back to normal performance or what.

  Understand the problem. You must connect the charger and decrease the battery below the battery to optimize it. Then you plug it in and it is fine. 60% it says plugged in and not charging and the GPU works both

  I believe that the error is indicating that your class file structure is not formatted properly as it seems to be trying to define several classes in one file.  I suspect it's going to be because of incorrect provision of braces.  Unfortunately, the pileup of the code is a bit much to go through you.

  I noticed that you have many nested named functions (functions within other functions) which causes problems as well.  All functions should stand on their own.

  Maybe you need to really do is to find a way to break this class file into separate files based on the feature class.

• Patty Burger Game health?

  Hey guys,.

  IM completely new to AS3.0 and flash also, I literally started today because its against completing me a mission design for United.

  so I started to do this prototype with a few basic features but im stuck now as snippets of sample code, our Professor of tutorial given we can't work to me.

  Registry of the mouse event functions
  bun.addEventListener (MouseEvent.MOUSE_DOWN, mouseDownHandler);
  bun.addEventListener (MouseEvent.MOUSE_UP, mouseUpHandler);

  tomato.addEventListener (MouseEvent.MOUSE_DOWN, mouseDownHandler);
  tomato.addEventListener (MouseEvent.MOUSE_UP, mouseUpHandler);

  Set a mouse down Manager (the user is dragging)
  function mouseDownHandler(evt:MouseEvent):void {}
  var object = evt.target;
  object.startDrag ();
  }
  Set a mouse Manager (stops user dragging)
  function mouseUpHandler(evt:MouseEvent):void {}
  var object = evt.target;
  object.dropTarget will give us the reference to the form of
  the object on which we have abandoned the circle.
  var target = object.dropTarget;
  object.stopDrag ();
  If the object exists AND that it is the blue button, then we change
  the text in the TextBox control.
  Given that obj.dropTarget is a form, we need its parent.
  If (target! = null & & target.parent == bun) {}
  textField.text = "Healthier".
  } else {}
  textField.text = 'UN healthy. "
  }
  }

  I'm basically dragging ingredients on the bun and when the text box is just saying that its healthy or not healthy, I want to be able to slide the bun of healthy ingredients, but have a "health bar" decrease or increase depending on what you drag on the bun.

  Thus, for example, the player moves a slice of tomato on bread, the health bar starts to say 20% she makes more "safety" and if the player drags the bacon on the bun the health bar loses 'safety. "

  IM really out of my depth now, I know what needs to be done (pseudo code ish lol) but I don't have the experience to do so.

  If someone could help me that would be GREAT FREAKING!

  see you soon

  Just do what I said and use the code that I have offered in place of what you had.  With your event listeners to add in...

  bacon.myPoints = - 20;

  tomato.myPoints = 20;

  And you should not having to have a stop() command in this function.  Stop() is an order of chronology, nothing more than that.  So unless you move along the timeline by dragging and want to stop in any framework you happen to be in when you drop an object, it is not necessary.

• What about Flash Player 'Next '?

  I saw the Flash Player Flash player 13 12 jump and I thout it's time 'next '.

  But I've not seen anything like that.

  When Flash play "Next" beta is ariving?

  As others have said, Adobe has chosen to continue to improve the current Flash runtime architecture. Flash ActionScript and player "Next" "Next", as they were known, is more expected.

  To learn more about the most recent plans, I recommend you take a look at the roadmap for Adobe for the Flash execution environments. It includes an explanation of the decision to Adobe about 'Next', and it's a little information on releases planned until early 2014. I assumed that this document will soon be updated to include information on the further development planned for later in the year, so stayed tuned.

• Windows Media Player 11 - Seek Bar not synchronized

  Recently, when I play the audio files in Windows Media Player 11 on Vista, the tab bar of the applicant appears and begins to move. However, if I shift it to another part of the song, little matter where I put it, it remains at the beginning of the song. Not necessarily at the beginning, but just not where it should be. The bar maxes and time keeps ticking. I can't move to any part of the song and the timer might hit easily 12 minutes for a 5 minute song as it plays. Any help to solve this? I recently installed Myst V on my computer, but am unsure if this problem started before or after.

  Do you see the correct length of MP3 files affected in the WMP library?

  I suggest that you try to repair these files with MP3 validator (after saving the files).

• I downloaded the latest version of flash player, does not?

  I just got my computer back to be fixed and I'm redownloading everything I need.

  I have a Mac OS X Version 10.7.5 and I downloaded the latest version of flash player for it. It seems to be installed because there is a window opens saying "Thank you, enjoy flash player." or something like that after I downloaded the flash player.

  I tried several times and I STILL can't watch videos or doing things that require flash player.

  I went to my preferences system, clicked on Flash Player and went to the progress bar, and he says "plug-in version 11.9.900.117 is installed."

  However, when I go to this page: http://helpx.Adobe.com/Flash-Player.html

  And I click the "check now" button to see if flash player has been installed on my computer, it says:

  "Sorry, Flash Player is either not installed or not enabled.

  Please proceed to step 2. »

  And so I did and downloaded AGAIN. I saw the same thing once I reloaded the page and try again.

  I don't have an anti-virus program, so it can't be that.

  The flash player is enabled?

  How can I check if it has activated activate / it?

  It is usually in the Tools section of your browser.

• How to make a bar of "health"?

  Hi, I need a tutorial on how to create a bar of 'health' - I don't have a better word for it, but my idea is to have a bar (showing the happiness of a pet) and whenever you press a button - the pet gains happiness - and the bar 'health' develops. What it is called and is at - it a guide I can read telling me how to create such a code?

  Create a rectangular movieclip for the bar and adjust its width or height property.  Example, were bar is the name of the instance of the health bar abd btn is the instance name of the button

  bar. Width = 0;

  var growValue:Number = 10;

  btn.addEventListener (MouseEvent.CLICK, growBar);

  function growBar(evt:MouseEvent):void {}

  bar. Width += growValue;

  }

• audio cd playback on blu - ray player

  I have a Sony BDP Blu ray player BX320 and looking to play audio CDs.  The Blu - ray player is connected to a sound bar Vizio via HDMI connections at each end and all works well, both dvd and cd audio.

  The problem is that I'm also enjoying my Bose sound with speakers system in several rooms.  It is connected via a receiver of Techniques very old with only the rca inputs.

  So finally, I would like to read my DVDs through the current installation and audio CDs through the receiver of Techniques to the Bose speakers.  The problem is that the receiver Techniques accepts only the rca inputs.

  I tried to connect the Blu - ray player to the receiver via the digital coaxial Techniques using a digital audio coaxial cable to a double (female RCA to RCA male) separator to the receiver - with the TV/soundbar in the wide receiver.  But it does not work.

  Is it possible to make these connections?

  Technical salute!

  It will work not only with the help of a separator, because you're dealing with analog and digital signals. In this case, you will need an analog converter instead of just a digital splitter. However, Sony does not guarantee complete compatibility/functionality of the use of converters/dispatchers of part 3.

  If you have a TV with HDMI input and output audio RCA, you can also connect your Sony Blu - ray player to your TV via HDMI and audio system via the audio output RCA on the TV without needing the converter/splitter. Then put the audio from your TV on external speakers.

  If my post answered your question, please mark it as "accept as a Solution.

  Thank you

• Collision problem

  Now, I do a game as the player I need dodge the falling stone (I animate it in the timeline) sky... and when to get company, the health bar will decrease. However, when I duplicate the stone in the 3 gems, when hit the player only will decrease life bar with a stone only health. May I know why this is happening? why two other stones does not? That's what my code looks like:

  Your code seems to only the target object, identified as "stone".  If there are more stones, then you must test each of them.  What did you do to make each stone unique targetable?  You can place references to these in an array and loop through the array, as in...

  var stones: Array = new Array (stone1, stone2, stone3);

  for (var i: uint = 0; i

  {if (Stones [i] .hitTestObject (Player)}

  process hit

  }

  }

  but then, you could also probably just something in the sense of...

  collision detection

  If (stone1.hitTestObject (player): stone2.hitTestObject (player) |)

  STONE3.hitTestObject (Player))
