Question

Any thoughts on this, i can get it to run but can't pass code around and the button doesnt move around.

i didnt pass the student, or the app.java.

What will you learn

Combined use of Timer and the tracking of user interactions

Deliverables

app.java

myJFrame.java

myJPanel.java

and other necessary Java files

Contents

The objective of the lab is to create a game in which the player has to click on a moving student-button to score.

The student button has to move constantly (using the timer)

The application has to keep the score

The actual score has to be shown.

Implement at least one of the extras listed below (3 to 7)

Level of difficulty: High

Level of usefulness for the final project: Very High

I am giving you:

The timer example

The new hybrid student-button (use yours from Lab 09)

The mouse motion and mouse click examples

The null layout example

Suggestion: start with the basic timer Java example and made the necessary changes to it.

Suggested steps:

Get the student button moving

you need the get timer started

you need a null layout (check the layout Java examples)

you need to set a different position for the button every time the timer ticks

Keep the score on a separate button, every click on the student button increases the score by 1.

When these two things are working change the image of the student button when it is clicked

When 3 is implemented, add a slider to make the button move faster or slower

you need to use the setDelay() method applied to the timer

When 4 is implemented, make the movement smooth instead of jumping from one place to another place very far away

Makes the student-button run faster when the mouse approaches it

When 5 and 6 are implemented, then do whatever else you want to add to it

Here is a code where u can make the button move constantly for the student.Hope this will be helpful for you:

this is my xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/backgroundblank" >
                  <Button
                    android:id="@+id/Button01"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:background="@drawable/black1" />
</RelativeLayout>

this is the code

public class tested extends Activity {

Button buttonblack;
int score=0;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.tested);


    buttonblack = (Button)findViewById(R.id.black1);
    buttonblack.setOnClickListener(new View.OnClickListener() {

              public void onClick(View v){
              //score+10(i dont know how to make score +10 if the button clicked)
              //if the button clicked
              //Do some logic here
                                         }                
            });

if (score = 100){
         //the speed of move are increase more fast
                }

}
