• Management change of HPSMH Collision detection

  Hello world

  We want to just implement collision detection mechanism in the management of change HPSMH. That means that if a CR was raised with a service assigned within a specific date range (say from 2nd to 4th month) .then if any new CR is triggered with the same affected service in the same amount of time then it will show a validation that the services concerned has already been used in a few other CR in the same amount of time.

• Catalog cannot be displayed in a table element? Is it possible to do them in a format similar to an unordered products list unordered list?

  Hello to the BC community,

  As indicated above, catalog cannot be displayed in a table element? Is it possible to do them in a format similar to an unordered products list unordered list? Overall, I'm looking to create a sensitive site and I like what the general store looks like, I just want to set the flow of catalogue items as I can with products. List items would be great for a catalog item, but I can't seem to locate it in the documentation that comes with BC. I could be completely missing it and if I did, I'm sorry! Thanks in advance for any help I can get with this topic!

• In ActionScript 2 simple Collision detection?

  I'm doing a simple maze game, but the collision detection doesn't work. I have the player moving with the arrow keys, and I'm doing so that when the player collides with the wall, it goes to a certain range. I have this code in the wall clip:

  onClipEvent (enterFrame) {}

  If (_root.player.hitTest (this))

  {

  gotoAndStop ("death");

  }

  }

  Name of the instance of the player's 'player' and the wall instance name is "walls1". When the player hits the wall, the player goes right through it. I'm sure it's something with the collision, not the 'gotoAndStop ("death")"; because I've tested it with "gotoAndStop (5);" and the player is still through the wall.

  If someone could help me, I would really appreciate it. Thanks in advance!

  What object expect you goto frame 5 ("death")?

  You should move your code to the main timeline and target objects.

• Collision detection changes the location of the MovieClip at random?

  Hello

  I was woundering how I had to code a program in AS3 on collision detection, it would change one of the objects collide at a random X & Y location?

  something like that, but works...?

  ship.addEventListener (Event.ENTER_FRAME, enter_frame);

  function enter_frame(event:Event):void {}

  {if (Ship.hitTestObject (target)}

  Target._x = random (1000)

  Target._y = random (1000) ;}

  }
  
  

  Found how do, but it does not work

  It is an AS2 implementation using the random method in your event handler function.  For AS3, use the Math.Random () as a multiplier and the properties of AS3 position (x / y, not _x/FLF).

  ship.addEventListener (Event.ENTER_FRAME, enter_frame);

  function enter_frame(event:Event):void {}

  {if (Ship.hitTestObject (target)}

  Target.x = Math.random () * 1000;

  Target.y = Math.random () * 1000;

  }

  }

• Slider & amp; Collision detection issue

  I couldn't find anything to help solve my problem thanks to my various research and turned to the publication. First - I am strictly a fan and try to create a timeline of the biography of a genealogy site that I am building.
  I have a scroll bar with a graph like the dredger pocket watch. What I hope to achieve, is that when the Watch has crept along the timeline and is is arrested on a marker (shown as a year), I'd like to pop up the relevant text on this date in time.
  
  My cursor is a movieclip and markers of the year are buttons. Through my research, it seems that I need to use both the collision detection and a certain type of load a script attached to it. It is quite possible that I am too far from my skill level, but I wanted to tender hand in case there may be help for me.
  
  I don't really have any code to show that I am very uncertain as to what would be the code appropriate to begin with. You can see an example of what I'm trying to accomplish here-> my scroll bar
  
  I currently have the text attached to the "over" frame in the button for example.
  
  Thank you in advance,

  Hello

  A quick solution to a situation that involves no collison detection must follow the x position of your clock instead, Minesweeper movieclip. You can use collision detection if you want, but by the way you set up your movie, it will involve a lot of targeting and recovery of the property. This track requires that you only add a few lines to a code you already have.

  Follow these steps

  (1) from the main stage, double-click your mc with the clock and the line in. Create a new layer and put 2 on that dynamic text boxes. Give the first instance of 'xpos' name text box and the other an instance name of "marker". XPos position near the bottom right of the scene and the marker on the opposite side. We will use these boxes for testing.

  2) click on the Actions layer and look for the line that says:

  ratio = Math.round (this._x);

  This guy below

  XPos.Text = report;

  Test your movie and you should see your x on the lower post update when you drag the clock. By working? Well, that's what we want.

  (3) according to the type of line last in what follows

  space var = 3;

  If (ratio > 36 - space & ratio)<>
  Marker.Text = "1900";
  } else
  If (ratio > 172 - space & ratio)<>
  Marker.Text = "1915";
  } else
  If (ratio > 399 - space & ratio)<>
  Marker.Text = "1945";
  }

  OK - explanation - what is happening here is to check if the clock is on one of the markers and we send the right text to the other created textbox marker information previously. If you test your animation and drag toward the center of the 1900 marker you will see its position x is about 36. The space variable adds or subtracts 3 on this position so that we have a good size "struck the area. In other words, if the x position is between 33 and 39 while we are on the marker of 1900. 1915 marker is the same with the other two - between 169 and 175, between 396 and 402 is marker of 1945.

  You can now replace the marker.text = "1900" line with what you want. You can make the box marker text a movieclip and it melted or slide in with the information you want.

  If it helps, then remember to delete the xpos off stage text box and delete the line of script that uses it. It was just to test.

• Collision detection - then click on next picture

  Hello
  I just took the collision detection works on my classes, but I was not able to get the movie to go to another frame on the collision. What's my problem - I can't use go to 'Film1' in the handle on me, Manager of collisionData. For some reason, it won't let me SO I tried to call another Manager to the statement, moviejump = true. It also did not work - pointers please? Thanks for any help!
  

  Just set a variable in your collision Manager (a global variable would be easier), which means a frame break. for example:

  on ' t handle me, collisionData
  frameJump = true
  end

  Then, during your exitFrame script, check if this variable has been set:

  on exitFrame me
  If frameJump then
  go to section 3
  end if
  end

• collision detection: custom class and table

  so I do a shooter from top to bottom for the pleasure, but have been struggling as I am new to programming.

  I have

  var player: player = new Player();

  enemy var: Array = new Array();

  now I searched on the net, but that's what I tried to work with.

  public void checkCollisionWithShip(): void {}

  for (var e = Enemies.length - 1; e > = 0; e-) {}

  If (Enemies [e] .hitTestObject (player)) {}

  trace ([e] Enemies);

  Life = 1;

  updateUI();

  trace ("ship collision!");

  }

  }

  }

  However, whenever my (player) ship hits an enemy, nothing ever happens.

  looking forward to your answers.

  Thank you very much for your time.

  Unfortunately the code that you decide should be shown is not code that needs to be shown.  Which calls the function where the collision is detected?  I don't see anything for this.

• Collision detection problem

  Hey guys,.

  I practice so the creation of a platform game. I have a movement system works, but when you try to add collision with platforms I have a problem.

  I did add each platform in a table and then check for the collision between the player and each platform, since I have just a bunch of instances without the platform symbol name on my stage. The problem with this is that my jumping code, I use a Boolean "onGround" value, which determines whether or not the player is "on the ground". And since my loop "foreach" across ALL platforms, even if the player is on a platform of some, there are other, it won't, and if it returns the onGround Boolean false.

  It's a problem with my code of jumping in general, I wonder where I get out of here. If I need to change my code from jumping, or change the collision, or what. Any ideas would be great. Here is my code:

  Thank you

  PS what is happening right now with that code is that the player hit the platform and stops, but onGround rest false

  Probably, there is too much code for anyone to really go. However, from what you said on your loop for:

  for each {(var plate-forme: DisplayObject dans platformArray)}

  If (platform.hitTestPoint (player.x, player.y + 20, true)) {}

  Vy = 0;

  onGround = true;

  }

  }

  I think what you want is to put a break; in there right after onGround = true; -C' is to say stop the treatment when you find a ground plan.

  Also, there are a couple of collision of good systems out there that might make this a little easier and more robust. Take a look at the Kit of detection of Collision (CDK):

  Dear adamlewen
  If you want to remove each hittest movieclip, you must do it in a loop "for". so you can detect the hit test and make the corresponding visual effect.
  Here is a sample file: take a peek...

  Hi cmersit,

  Why do you need that for? You have not said before...

  Well, create a local to c [j, I], move it to the for loop and connect with the release of ReplaceArraySubset. It's going to hurt needs memory and processing speed and doesn't help here. Replace [result] with a local of c [j, I] for this example. Otherwise use a shift register in the outer loop!
