I am confused on how I would set up 6 different images. I have to stick to the 9

Question

I am confused on how I would set up 6 different images. I have to stick to the 9 import classes I have. I need to set up six images to be used in an algorithm that that will show dice roll results. Basically, if a 3 and 5 are rolled then I will need my program to show a pic of 3 dice and 5 dice. How would I line up the images in the this driver program??? I am not asking for the algorithm, I just want help coding in the set up, if that makes since? The section of code I have in Bold is where I think I am to set up images, I am not sure if anything I have in bold is correct or on the right path?

Thank-you

Explanation / Answer

I’ll explain you on how to set up all 6 images. As you have not provided PigDice class , I can just explain the logic to setup the images. First of all, you have to define an array of Image objects, outside all the methods, so that it can be accessed from anywhere within the program.

I have defined an array of Image objects under the ImageViews declaration.

private Text sumText;

private PigDice p;

private ImageView die1View, die2View;

//defining an array of images

private Image images[];

Then , inside the start method, initialize the array and fill with Image objects as shown below.

images=new Image[6];

images[0]=new Image("file:C:\Users\user\Documents\DieImages\die1.jpg");

images[1]=new Image("file:C:\Users\user\Documents\DieImages\die2.jpg ");

images[2]=new Image("file:C:\Users\user\Documents\DieImages\die3.jpg ");

images[3]=new Image("file:C:\Users\user\Documents\DieImages\die4.jpg ");

images[4]=new Image("file:C:\Users\user\Documents\DieImages\die5.jpg ");

images[5]=new Image("file:C:\Users\user\Documents\DieImages\die6.jpg ");

Note that it is important to specify the path of each images and keeping the prefix ‘file:’.

Also try to put two backslashes instead of one in the path name, or else the file may not be loaded.

After this, you can easily use these 6 images in your imageviews. I have provided an explanation in processButtonPress() method on how to set proper dice images in each draw
