Creating The Game - 10/03/2013 Continued

This is a continuation of the 10/03/2013 Update post. In this section of the update I will be showing how the pause and death menus were implemented into the game. To start with just like the controls page on the main menu screen I started with two boolean variables each one indication whether of not the game was paused or if the player was dead, these both started as false in the beginning. If the player hit the P button on the keyboard then the game would become paused for this I had to update every section of the play class with the code below to allow the game to draw the menu when the boolean turned to true and also allow the user to use the option that are displayed when the pause menu is shown, when the P button is hit again the menu will disappear allowing the game to continue. The code for all of this is below:

Menu Initialisation

 pauseMenu = new Image("data/PausedMenu.png");
 deadMenu = new Image("data/deadMenu.png");

Sound Initialisation

 death = new Sound("data/Death_Tune.ogg");

Render Loop Updated

public void render(GameContainer gc, StateBasedGame sbg, Graphics g) throws SlickException {

 if (!paused && !dead){

  BG.draw(0,0);
  BlockMap.tmap.render(0, 0);
  g.drawAnimation(player, x , y);
  g.drawAnimation(ai, AIx, AIy);

 }else if(paused){
  pauseMenu.draw(0,0);

 }else if(dead){
   deadMenu.draw(0,0);
 }

}

Logic Loop Updated

public void update(GameContainer gc, StateBasedGame sbg, int delta) throws SlickException {

 Input input = gc.getInput();
 float floatDelta = delta*0.1f;

 mouseX = gc.getInput().getMouseX();
 mouseY = gc.getInput().getMouseY();

 if(dead && !paused){
   
  if ((mouseX > 468.0 && mouseX < 762.0) && (mouseY > 395.0 && mouseY < 495.0)){
   if(input.isMousePressed(Input.MOUSE_LEFT_BUTTON)){
    y = 32f;
    x = 32f;
    AIx = 480;
    AIy = 640;
    dead = false;
    Level1.play();
   }
  }

  if ((mouseX > 468.0 && mouseX < 762.0) && (mouseY > 552.0 && mouseY < 652.0)){
   if(input.isMousePressed(Input.MOUSE_LEFT_BUTTON)){
    System.exit(0);
   }
  }

 }

 if(paused && !dead){

  if ((mouseX > 511.0 && mouseX < 730.0) && (mouseY > 375.0 && mouseY < 460.0)){
   if(input.isMousePressed(Input.MOUSE_LEFT_BUTTON)){
    paused  = false;
   }
  }

  if ((mouseX > 511.0 && mouseX < 730.0) && (mouseY > 500.0 && mouseY < 585.0)){
   if( input.isMousePressed(Input.MOUSE_LEFT_BUTTON)){
    System.exit(0);
   }
  }
 }

 if (!paused && !dead){

The code above checks to see which of the states the player is currently in, if the player is paused then the game checks to see if the played is clicking in any of the correct areas to perform the desired actions from the pause menu, this is also done if the player is dead and is trying to click on the restart button on the death menu. The very last line of the code above checks to see if the user is in a normal state e.g. not dead or paused and if so the normal game logic continues uninterrupted. Because the death menu is now set up ready to be used the correct code can be added to the AI collision detection to show the death menu when hit and also when the played falls down a pit in the level. The code for both of these is shown below:

Falling Death Code:

  if (y > 960){
   dead = true;
  }

Updated AI Collision Code:

  if(playerPoly.intersects(AIPoly)){
   dead = true;
   Level1.stop();
   death.play();
  }

As the main function of the game are now in place I can reuse all of the code that has been written for this level to create a second level for the game, but lastly on this level I will have to create an exit to the second level by using the door sprite that Stephen has created. The simple code to add a door to the level is below and the code to continue onto the next level will be added when the level is completed.

Initialising the Door:

door = new Image("data/Exit.png");

Drawing the Door (Updated Render Loop):

public void render(GameContainer gc, StateBasedGame sbg, Graphics g) throws SlickException {

 if (!paused && !dead){

  BG.draw(0,0);
  BlockMap.tmap.render(0, 0);
  door.draw(1216, 576);
  g.drawAnimation(player, x , y);
  g.drawAnimation(ai, AIx, AIy);

 }else if(paused){
  pauseMenu.draw(0,0);

 }else if(dead){
  deadMenu.draw(0,0);
 }

}
