Hi All!

I want to make a turn-based game and i don't know how to notify my Player/Game object about the input from the player.

My main routine should be:

- wait for input from the player
- process input
- process npcs
- repaint the screen.

But how should i send the result of the keyListener to the Game object? Dont want to do it with a global variable.

What should be the best way to do this?

cu,
aankhra

Here is a loop:

1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
12  
13  
14  
15  
16  
17  
18  
public static void main(String[] args) {
      Main main = new Main();
     
      while (!main.exit) {
         main.game.changeResolution(main.frame.getWidth(), main.frame.getHeight());
         main.input();
         main.logic();
         main.render();
         
         try {
            Thread.sleep(main.timeToSleep);
         } catch (InterruptedException e) {
            e.printStackTrace();
         }
      }
     
      System.exit(0);
   }


Sending Input to Game:

1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
12  
private void input() {
      if (mouseClick != null) {
         getDeviceCoords(mouseClick);
         game.mouseClick(mouseButtonPressed, mouseClick);
         mouseClick = null;
      }
     
      if (mouseLocation != null) {
         getDeviceCoords(mouseClick);
         game.mouseLocation(mouseLocation);
      }
   }


After this you may want to create class or a collection that stores the inputs and the process them within the logic.

Like so:

1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
                       if(!plays.isEmpty())
            for (Point click : plays)
               world.playCard(player, click);
         
         if (!discards.isEmpty())
            for (Point click : discards)
               world.discardCard(player, click);

             if(turn.isPlayersTurn(ai)) {
         //TODO: add more advanced AI
      }

OK,

i assume, that your input() method implements a kind of a (Mouse)Adapter. My game will be controlled only by the keyboard. But how to notify the main object about the input? I want to pass the action (like Player.GO_WEST, or Player.USE_SKILL) to the game.logic()

ArrayList<KeyEvent> keysPressed = new (...);

public void keyPressed(...){
        keysPressed.add(evt);
}


public void input(){
      for(KeyEvent keys : keysPressed){
            switch(keys.getKeyCode()){
               case KeyEvent.VK_UP:
                   game.movePlayerUp();
                   break;
            }
      }
}


Make sure you add the required listeners to your class.

"class Main implements KeyboardListener"
