THE FLOWER-CATCHING BEE GAME

The following tutorial will teach you how to create a game using Greenfoot IDE (Integrated Development Environment).

STEP 1 - CREATING A NEW GREENFOOT SCENARIO

Launch Greenfoot

Click on "Scenario" -> add a "New Java Scenario"

Name the file and choose where to save it (existing folder or new folder)

STEP 2 - NEW GREENFOOT SCENARIO CREATED

Now you will see your new scenario, which includes two classes and a subclass by default:

World and the subclass My World

Actor

Each class we are going to create will be a subclass of the above classes and will inherit from them.

STEP 3 - ADDING BACKGROUND IMAGE TO MY WORLD SUBCLASS

Right click on "My World" subclass and click on "Set image"

First option: you can add the background by choosing it among Greenfoot backgrounds

Second option: click on the settings on the bottom left side and click on "Import from file...". Select the image you want as background.

It's important that your image has exactly the same size of My World. Double click on My World to check its size.

Adjust background image size to my world size: in the project folder find the folder "Images", open your background image and then click on "Tools" and "Adjust Size". Change its size to make it equal to My World size.

STEP 4 - CREATING A SUBCLASS OF THE ACTOR

Now we are going to create a subclass of the Actor, which will inherit all the methods from the Actor Class.

Right click on "Actor"

Click on "New Subclass"

In the section "nature", select the image "bee"

Name your class as "Bee"

Note:

Remember that all classes should start with capital letters.

STEP 5 - ADDING AN INSTANCE OF THE BEE SUBCLASS TO MY WORLD

We created the subclass "Bee" and now we will add an instance of this subclass to make it visible on the background.

Double click on "My World"

Add the code:

   addObject(new Bee(),200,100);

Always click on "Compile" to save the changes

Run your program

STEP 6 - MAKING THE BEE MOVE

Double click on "Bee" and add the following blocks of code in the Act Method:

To make the bee move straight forward:
move(5)

To make the bee turn when it hits the edges:

To make the bee move right and left:

 if (Greenfoot.isKeyDown("left"))  {turn(-4);} if (Greenfoot.isKeyDown("right")) { turn(4); }

Another possible option to add the moves of the bee is to add these blocks of code outside the Act Method, that is creating those methods separately and calling them in the Act Method (see demo game).

STEP 7 - ADDING THE FLOWER SUBCLASS

As we did for the Bee, right click on Actor and click on "New Subclass"

Click on the nature section and select "Flower2"

Name your subclass as "Flower"

STEP 8 - ADDING INSTANCES OF FLOWER SUBCLASS TO MY WORLD

Double click on My World

You can add the instances of the flower subclass in two different ways:

        Flower flo = new Flower();        addObject(flo,400,100);

or, as we did before for the Bee,

        addObject(new Flower(),150,250);        addObject(new Flower(),250,100);        addObject(new Flower(),500,400);        addObject(new Flower(),650,80);        addObject(new Flower(),50,450);

STEP 9 - ADD THE METHOD FOR MAKING THE FLOWERS DISAPPEAR

Now we have one Bee moving and 6 Flowers. We will make the flowers disappear when the Bee eats them.

Double click on "Bee"

Add the following method outside the Act Method:

         public void checkCollision()         {                if(isTouching(Flower.class))               {                      removeTouching(Flower.class);               }          }

call the method in the Act Method:

public void act()
{
      move(5);
      turnAtEdge();
      keyPressed(); checkCollision(); }

STEP 10 - ADDING THE SCORE

Now will add a visible score section on the top left side of the background to show the user how many flowers have been eaten progressively.

double click on "Bee"

first of all, create an int variable called "flowersEaten" at the top, outside the Act Method, and state its value when the game starts, that is 0 (no flowers have been eaten yet).

add the following code to the checkCollision Method, after removeTouching(Flower.class), to make the number of flowers eaten increase by one every time the bee eats a new flower

flowersEaten+=1;

now we will add the score section to track how many flowers the bee has eaten:

          MyWorld mw = (MyWorld)getWorld();          mw.showText("Score is: " + flowersEaten, 70,20);

NOTE:

showText is a method included in the World, so the class Actor doesn't include it by default. If we want to add the code for the score inside the "Bee" section, first of all we have to call the method from the World ( MyWorld mw = (MyWorld)getWorld();).

Then we can use the method to add the string and the position of the score label.

STEP 11 - ADDING THE CODE TO MAKE THE BEE STOP WHEN IT REACHES A SET OBJECTIVE

Double click on "Bee"

Add the following code to make the bee stop when it eats 4 flowers. The code must be included in the checkCollision method.

         if(flowersEaten == 4)         {              Greenfoot.stop();         }

STEP 12 - CREATING THE CACTUS SUBCLASS

Right click on "Actor"

In the section "nature", select the image "Cactus"

Name the object as "Cactus"

STEP 13 - MAKING THE BEE DISAPPEAR IF IT TOUCHES THE CACTUS

Double click on "Cactus"

Add the code inside the Act Method to make the bee disappear when it hits the cactus:

if(isTouching(Bee.class)){removeTouching(Bee.class); }

NOW IT'S YOUR TURN! LET YOUR CREATIVITY FLOW AND CREATE YOUR OWN GAMES! HAVE FUN!

Free online HTML code editor with instant live preview. Enter your code in the editor and see the preview changing as you type. Compose your documents easily without installing any program.
There is another online HTML editor which is using a WYSIWYG visual editor linked to the source editor but we found it necessary to create a separate composer where the TinyMCE is not overwriting the errors and gives more freedom and control. That particular editor corrects our code every time when considers something an error, even if we didn't want that. Now we can use non-standard tags and attributes, ASP.NET tags and more.

How to use the HTML code editor?

You will see the source editor pre-populated with a demo text when you load the website for the very first time, letting you experiment with the tool. Load this text any time you want using the allocated menu option. To open a new tag use the list above the text area. Close the opened tags clicking the close button on the very right side of the top section. This will close the items one by one in reverse opening order.

The main HTML composing area is using syntax highlighting to make the markup language tags easily distinguishable and more readable. The amount of characters is displayed along with the main control buttons: undo, new page, font-size adjuster, compressor and the main HTML Cleaning button which executes all checked cleaning options.

The preview area is located on the right side of the source editor and the changes are reflected here instantly to make HTML composing more human friendly. This section is using the Bootstrap CSS, which allows you to use the styles of the most popular front-end framework.

Scrolling further down you can find many useful integrated tools. Use the tag wizard to perform bulk operations on the code. Following the first tag name list column there are additional options to create new tags, replace them, delete them completely with their content, remove only the tags, delete the tag attributes of certain tags and it's possible to convert tables and lists to structured div elements. Besides the predefined iframe, table, link, span, image, form and list tags you can define and manipulate further tags entering them in the input fields. Every tag wizard action can be executed individually with the little play buttons or they can be set active checking the grey dots and apply them all together with the main button in the top-right corner of the window.

The most basic HTML Cleaning features are available and can be applied one by one or all active options at the same time. Clear out inline styles, unwanted classes and ids, empty tags, tags containing only one non-breaking space, successive spaces, comments. You can also get rid of all tag attributes (except the src of images and href of anchor tags) or remove every tags with one mouse click, making the document a plain text.

The replace tool can look and interchange text bits in the whole document, the content, the tag attributes, the styles or in the classes/ids. This doesn't support regular expressions.

The color picker is another important feature of the HTML code editor which lets us easily select the desired color and save them for later use. The most common code snippets can easily be copy-pasted in the editor.

The gibberish text generator populates the editor or the allocated area on the page with some basic Lorem Ipsum paragraphs.

Useful tips

Keep a backup of the content and always save the work progress.
Make sure you validate the HTML codebefore publishing to avoid errors.
