Entity properties

(Ryan C) #1

I’m wondering, is there a way to access an entity’s properties in the entity class, such as I start the entity class with public function FreindlyFlea(x:Number, Y:Number, FleaNumber:int) and I would like to access the property of Flea number in the flea class. what i am trying to achieve is to create a strategy game and only have to have one class for friendly units, not say 5 for individual units, and yes, its a game about fleas, don’t ask.

Couple of ways to do this, here is one. In the flea class make FleaNumber a public static var, so like,

public static var FleaNumber:int = 0;

Then wherever in your game that you would like to access it, just type theFlea.FleaNumber.

Hope this helped. It isn’t the best way to do this, but it will work!

I thought of that, however, what i am trying to do is to have lets say 5 entities using the same class but firing bullets from different locations, and the locations are predetermined. This was the only way i could think of, and if you have any other ideas that would be great, thanks, Ryan

The entity class has a property called name.This property distinguish instances between eachother.So you can add 5 entityes with different names like:

var setName_:string;
for(var i:int=1,i<=5,i++){
setName_="Flea"+i;
add(new FreindlyFlea(x_,y_,FleaNumber_,setName_);
}

and in flea’s class is something like this:

public var FleaNumber:int = 0;

and in constructor:

public function FreindlyFlea(x:Number, y:Number, FleaNumber:int,name:string)
{
//stuff
this.name=name;
}

And whenever you whant to acces the property of the specific instance of the entity Flea just do something like this:

//for example for 1st flea
var FleaInstance:FreindlyFlea = FP.world.getInstance("Flea1");
FleaInstance.FleaNumber=75;//idk did random number

Or …you can also use a public static vector for FleaNumber(not in flea’s class IMO tho).

Could you explain this bit please?, I put it into my code and then the game kept crashing when i tried to switch to the world…

(billy2000) #6

That piece of code was just a example. As it is over there it dosent work.All i meant by doing that for is to try to make u realize that u need different names for each instance u create of the entity fly. sry >.<

(Ryan C) #7

only problem… I have no idea how to extrapolate from that code… I’m still new to programming… :S

(billy2000) #8

Well then give a piece of your code,how you try to add them to your world.I gtg to sleep but if no1 still help you(witch i doubt cose everyone here is so awesome) i can try to help you more tomorrow :smiley:

package { import net.flashpunk.Entity; import net.flashpunk.Graphic; import net.flashpunk.graphics.Image; import net.flashpunk.utils.Input; import net.flashpunk.FP; public class FreindlyFlea extends Entity { [Embed(source = “Image_res/flea.png”)] private const FLEA:Class; [Embed(source = “Image_res/fleaHoverd.png”)] private const FLEAHOVERED:Class; [Embed(source = “Image_res/fleaDead.png”)] private const FLEADEAD:Class; [Embed(source = “Image_res/fleaSelected.png”)] private const FLEASELECTED:Class; public var FleaNormal:Image = new Image(FLEA); public var FleaHovered:Image = new Image(FLEAHOVERED); public var FleaSelected:Image = new Image(FLEASELECTED); public var FleaNumber:int = 0; var gameWorld:GameWorld = world as GameWorld;

	public function FreindlyFlea(x:Number, y:Number, FleaNumber:int)
	{
	super(x, y);
	graphic = FleaNormal
	setHitboxTo(graphic);
	this.name = name;
	}
	override public function update():void
	{
		// this is where I want to select fleas to shoot or where i was trying to
	}
	protected function changeState(state:int = 1):void
	{
		
	}
}

}

my code for the entity class. package { import net.flashpunk.Entity; import net.flashpunk.World; import net.flashpunk.utils.Input; import net.flashpunk.FP;

public class GameWorld extends World
{
	public var FleaIsDead:Boolean = false;
	public var FreindlyFleaSelected:Boolean = false;
	public var FleeCanBeSelected:Boolean = true;
	public var FreindlyFlea1Selected:Boolean = false;
	public var FleaCount:Number = 0;
	
	public function GameWorld()
	{
		// background here 
	}
	override public function update():void
	{
		super.update();
		
		//adding fleas//
		if (Input.mouseReleased)
		{
			
		}
		
		
		
		//firing//
	}
}

} and the gameworld class… i have just given up and rewritten [deleted] quite a bit to try and get a more concise code, but this is my first project… so its quite ambitious and will take a while.

yea wow the formatting screwed up badly on that last post, sorry

Surround your code with triple backticks.

```actionscript
your code here
```

very post. such help.

@nayrdux It looks like what you’re trying to do is store a list of fleas, allowing a player to select them. You don’t need to store this information inside of FreindlyFlea [sic] at all, since the fleas don’t care if they are selected or not.

public class GameWorld extends World
{
  /** The index of the selected flea, or -1 if none are selected. */
  private var _selectedFlea:int = -1;

  /** The list of all the FriendlyFleas. */
  private var _fleas:Vector.<FriendlyFlea>;

  public function GameWorld()
  {
    // Initialize the list of fleas.
    _fleas = new Vector.<FriendlyFlea>();
  }

  override public function begin():void
  {
    // Add some fleas to the world, storing them into the list of fleas.
    _fleas.push(add(new FriendlyFlea(25, 50)));
    _fleas.push(add(new FriendlyFlea(100, 85)));
  }

  override public function update():void
  {
    var clickedFlea:FriendlyFlea;

    if (Input.mouseReleased)
    {
      // Check to see if a flea was clicked and store it to clickedFlea.
      // If it was, determine the flea clicked.
      _selectedFlea = _fleas.indexOf(clickedFlea);
    }
  }
}

@zachwlewis me being the amateur and all how do i use that last bit? _selectedFlea = _fleas.indexOf(clickedFlea);

Haha in retrospect I guess I should have specified that I was answering the post about screwed-up formatting, not the question of the main thread. :stuck_out_tongue:

That’s up to you. I’d suggest looking into collidePoint and Input.mouseX and Input.mouseY.
