0.2 Parcheesi Assessment

In this assessment, you will build a UML object diagram that represents one specific Parcheesi game state. You will create a Player named Tara, represent four red Pawns, connect the Player to those Pawns, and use the Feedback System to check and revise your work.

1. 1. Create a new object diagram.

   Begin with a blank Violet object diagram. The first object you add represents one specific player in the game rather than the general idea of every possible player.

   Step 1 — Open a new object diagram

   Open Violet UML Diagramming Tool. Choose File | New | Static view | Object diagram.

   

   Step 2 — Create the Player object

   Select the Object tool and click the workspace.

   

   Double-click the new object node to open its Properties window.

   

   Set the object Name to Player, then click OK.

   

   Go to top

2. 2. Represent the first player.

   This Player represents Tara, the first player in the modeled game state. Use fields to record the information that matters for this diagram: the player's number and name.

   Step 1 — Add the first field

   Select the Field tool in the Diagram tools menu.

   

   Click the Player object to add a field.

   

   Step 2 — Open the field Properties window

   Select the Select tool.

   

   Double-click the new field to open its Properties window.

   

   Step 3 — Set the player's number

   Change the field Name to Number. Change the field Value to 1.

   

   Click OK and confirm that Player now shows Number = 1.

   

   Step 4 — Add Tara's name

   Add a second field to Player. Set the field Name to Name. Set the field Value to Tara, then click OK.

   

   Go to top

3. 3. Represent the Pawns.

   A class can be used to create multiple object instances. In this game state, Tara has four red Pawn objects. Each Pawn uses the same object type but has its own Number value.

   Step 1 — Create the first Pawn

   Use the Object tool to add another object node. Double-click the object and set its Name to Pawn. Add a field named Number and set its Value to 1. Add a field named Color and set its Value to Red.

   

   Step 2 — Create the remaining Pawns

   Create three additional Pawn objects. Set every Pawn Color to Red. Set the Pawn Number values to 2, 3, and 4 so the four Pawns are numbered 1 through 4.

   

   Go to top

4. 4. Connect the Player to the Pawns.

   The four Pawn objects exist, but the model does not yet show that they belong to Tara's Player object. Add four reference fields to Player, then connect each field to the matching Pawn object.

   Step 1 — Add the Pawn reference fields

   Add four fields to Player named Pawn1, Pawn2, Pawn3, and Pawn4. Leave the field values available for object-reference connections rather than typing Pawn data into the fields.

   

   Step 2 — Connect Pawn1

   Select the Object reference (from field) tool.

   

   Drag from the value area of Player.Pawn1 to the Pawn whose Number is 1, then release.

   

   Step 3 — Connect the remaining Pawns

   Connect Player.Pawn2 to the Pawn numbered 2. Connect Player.Pawn3 to the Pawn numbered 3. Connect Player.Pawn4 to the Pawn numbered 4.

   

   Step 4 — Check the completed model

   Confirm Player shows Number = 1 and Name = Tara. Confirm there are four Pawn objects, all with Color = Red and Number values 1 through 4. Confirm Pawn1, Pawn2, Pawn3, and Pawn4 each reference the Pawn with the matching Number. Go to top

5. 5. Save, submit, and revise the diagram.

   Save the Violet file, submit it to the Feedback System, and use the returned feedback to correct the diagram before submitting your result to Canvas.

   Step 1 — Save the Violet diagram

   Choose File | Save in Violet. Use the base filename Parcheesi 0.2 LastName. Confirm the saved file ends with .object.violet.html.

   Step 2 — Submit the diagram to the Feedback System

   ZIP the .object.violet.html file itself. Do not place it inside another folder before zipping. Use the ZIP filename Parcheesi 0.2 LastName.object.violet.html.zip. Submit the ZIP file to the Feedback System.

   Step 3 — Resolve any Feedback System errors

   If feedback identifies an error, reopen the Violet file and correct the diagram. Save the corrected file, ZIP it again, and resubmit it. Repeat the correction cycle until the required feedback is resolved.

   Step 4 — Submit your result to Canvas

   Submit the resulting Feedback System URL to Canvas as directed by your course. Go to top
