creating a pre-menu level select screen
- by Ephiras
Hi I am working on creating a tower Defence java applet game and have come to a road block about implementing a title screen that i can select the level and difficulty of the rest of the game. my title screen class is called Menu. from this menu class i need to pass in many different variables into my Main class.
i have used different classes before and know how to run them and such. but if both classes extend applet and each has its individual graphics method how can i run things from Main even though it was created in Menu.
what i essentially want to do is run the Menu class withits action listeners and graphics until a Difficulty button has been selected, run the main class (which 100% works without having to have the Menu class) and pretty much terminate Menu so that i cannot go back to it, do not see its buttons or graphics menus. can i run one applet annd when i choose a button close that one and launch the other one?
IF you would like to download the full project you can find it here, i had to comment out all the code that wasn't working
my Menu class
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class Menu extends Applet implements ActionListener{
Button bEasy,bMed,bHard;
Main m;
public void init(){
bEasy= new Button("Easy"); bEasy.setBounds(140,200,100,50); add(bEasy);
bMed = new Button("Medium");bMed.setBounds(280,200,100,50); add(bMed);
bHard= new Button("Hard");bHard.setBounds(420,200,100,50); add(bHard);
setLayout(null);
}
public void actionPerformed(ActionEvent e){
Main m = new Main(20,10,3000,mapMed);//break;
switch (e.getSource()){
case bEasy: Main m = new Main(6000,20,"levels/levelEasy.png");break;//enimies tower money world
case bMed: Main m = new Main(4000,15,"levels/levelMed.png");break;
case bHard: Main m = new Main(2000,10,"levels/levelEasy.png");break;
default: break;
}
}
public void paint(){
//m.draw(g)
}
}
and here is my main class initialising code.
