Hi everyone!! I’m new, so please forgive me if i’m posting in the wrong place.

It’s lame, but i’m having trouble with the skybox tutorial. When i try to apply the jpg’s to form the BitmapCubeTexture, i get an error saying that BitmapCubeTexture only accepts 1 argument. But I know you need 6!

Sorry, English is not my first language and i’m having trouble explaining myself. Take a look at the code, please.

var cubeTexture:BitmapCubeTexture = new BitmapCubeTexture(
     Cast.bitmapData(EnvPosX), Cast.bitmapData(EnvNegX), Cast.bitmapData(EnvPosY), 
     Cast.bitmapData(EnvNegY), Cast.bitmapData(EnvPosZ), Cast.bitmapData(EnvNegZ)
    ); 

I have no idea how to fix this, or whatever it is i am doing wrong. So i’d appreciate some help. Thank you

Please post the whole code you have. The line you’ve posted is ok.

In the example notice the following lines:

// Environment map.
  [Embed(source="../embeds/skybox/snow_positive_x.jpg")]
  private var EnvPosX:Class;
  [Embed(source="../embeds/skybox/snow_positive_y.jpg")]
  private var EnvPosY:Class;
  [Embed(source="../embeds/skybox/snow_positive_z.jpg")]
  private var EnvPosZ:Class;
  [Embed(source="../embeds/skybox/snow_negative_x.jpg")]
  private var EnvNegX:Class;
  [Embed(source="../embeds/skybox/snow_negative_y.jpg")]
  private var EnvNegY:Class;
  [Embed(source="../embeds/skybox/snow_negative_z.jpg")]
  private var EnvNegZ:Class; 

They’re placed in variable declaration piece of code. The code in brackets [] is used to embed external files into your program. These are the images from which the skybox is composed. Paste this code into your class and make sure you have embeds/skybox folder with jpg’s inside.

Thank you, the problem is fixed now. I thought i read somewhere that it was enough importing the images to the library, but apparently i misunderstood. Thanks again!
