Woohoo! We are actually going to create than darn main menu now. Since we are going to be clicking past the main menu we are going to have to create a screen to hold our formal game. So to do this we will create a new class in the package and call it GameScreen, then build the base model the same as shown below (Note: Where it says AdlermacGame, replace that with the name of your name Game Class):

Now that we have created the next screen, we will move to placing a button on the screen that can be clicked. To do this, I simply made a very simply button that reads “play” and is 200px wide by 100px tall:
This button was then placed in the Assets folder. Then its pretty simply to draw it onto our screen, you simply will need to add this line of code within the render method of the MainMenuClass:
1

|
//draws the play button in the middle of the screen
game.gameBatch.draw(new Texture("playbutton.png"),300,190);
|
Once it is added, we need to see when the person clicks on it, we do that by using the previous (is.touched) method before for creating all of our objects. I am going to leave the object creation portion of the code in due to its complete awesomeness! ha..ha.. anyways, the new section of code is the following:
1

//Code snippet that runs when being touched
if(Gdx.input.isTouched()){
//Creates a new Object (which is our moving thingies) with a random x and random y speed
MyObject myObject = new MyObject(MathUtils.random(-5,5),MathUtils.random(-5,5));
//Adds our new created object to our object array
myObjectArray.add(myObject);
//Checks if the click was in the bounds of the Play Button
if(Gdx.input.getX() > 300 && Gdx.input.getX() < 500 && Gdx.input.getY() > 190 && Gdx.input.getY() < 290){
game.setScreen(new GameScreen(game));
}
}

And with that addition, we will be able to switch click the play button and bring you to the next screen, albeit, blank. But, perfect for our next phase of work!
