Don't know any other way than (username.equals(u1) && username.equals(u2) && username.equals(u3))
[QUOTE=Xeon06;27274439]Took a break from my main project to try out an idea I had: JavaScript multiplayer game. It worked out... kinda. You can try it (using Chrome preferably):

Arrow keys to move. You're the blue guy.
Of course there's a lot of latency seeing as this is HTTP, and you have to go check if there are any updates for you seeing as you can't directly "receive" stuff. I think it could work for a slow-paced game, maybe turn-based like chess or such.[/QUOTE]
Have a look at HTML5 Websockets.
[QUOTE=CommanderPT;27278687]I know that there is a help thread but I never got any help there.
Can somebody just help me real quick with this:
[code]
if(username.equals(u1)){
do stuff
else
do other stuff
}
[/code]
A very basic IF statment. The thing is, can I make it so that it checks if username.equals several different things? I got three usernames and I want to check them all, so it is basically like if username.equals(u1, u2, u3);
Is this possible? So that I don't have to write multiple if statements.[/QUOTE]
if (username == u1 || username == u2 || username == u3)

It would need OR statements
(username.equals(u1) || username.equals(u2) || username.equals(u3))
But that is the same as an if, else if except it doesnt allow to do different things when diferent people log in
[QUOTE=PiXeN;27278928]if (username == u1 || username == u2 || username == u3)[/QUOTE]
But of course. So simple! Thank you and to rest who posted as well.
[QUOTE=PiXeN;27278928]if (username == u1 || username == u2 || username == u3)[/QUOTE]
Wouldn't and be more appropriate in this case? Seeing as he wants to check if it's equal to them all.
[QUOTE=iNova;27278956]Wouldn't and be more appropriate in this case? Seeing as he wants to check if it's equal to them all.[/QUOTE]
And would be if username equals all three u1, u2 & u3
But technically thats imposible
Usually a value only equals to exactly one other value.
[QUOTE=ZeekyHBomb;27279011]Usually a value only equals to exactly one other value.[/QUOTE]
Not if all the other values are the same?
I'm guessing u1 u2 u3 are variables here, not strings so it's very possible.

Um, they are strings. Names to be exact, I want it to check if what the user enters matches any of them.
Edit:
It appears to work when I use the method Richy19 posted.

Ahh, I see. You didn't specify if any or all :buddy: Mine works if you want to check if it's equal to all of them.

The problem is that if I enter u1's username and u2's password it still works.

[code]
[b]loginbutton.addActionListener(new loginaction());[/b] //Possible to add anything here that makes for example, a JFrame appear or dissappear?

class loginaction implements ActionListener{
public void actionPerformed (ActionEvent e){
String u1 = "Peyman Torabi";
String p1 = "doodle";
String u2 = "Gordon Freeman";
String p2 = "crowbars4life";
String u3 = "Duke Nukem";
String p3 = "boombaby";
String username = JOptionPane.showInputDialog(null,"Enter username");
String password = JOptionPane.showInputDialog(null,"Enter password");
if(username.equals(u1) || username.equals(u2) || username.equals(u3)){
if(password.equals(p1) || password.equals(p2) || password.equals(p3)){
JOptionPane.showMessageDialog(null, "Access granted!");

This is a larger chunk of the program that I am working on. It is very simple, I am not very good at programming yet. I am just wondering, is it possible to make for example, a window disappear when the action listener is triggered? A window that is in the main class.
[QUOTE=CommanderPT;27279200]The problem is that if I enter u1's username and u2's password it still works.[/QUOTE]
Because you're checking if it matches any of the usernames and any of the passwords. Check passwords by the specified username.
[QUOTE=iNova;27279237]Because you're checking if it matches any of the usernames and any of the passwords. Check passwords by the specified username.[/QUOTE]
Guess I'll have to have several if statements then instead of just one. So that if it finds a username it will check the respective password.
Wouldn't a user list indexed by username containing password work? Assuming you have the library to do it:
[code]
if(Users.ContainsKey(uX))
{
if(Users[uX] == GivenPassword)
{
// Valid user
}
else
{
// Invalid password
}
}
else
{
// Not a valid user
}
[/code]
Though it may be a sledgehammer to crack a nut.
In C# this would be a Dictionary<string, string>.

If, else if would probably be easier but i think you could also do
[code]( (username.equals(u1) && password.equals(p1)) || (username.equals(u2) && password.equals(p2)) || (username.equals(u3) && password.equals(p3))[/code]
But as i say the only way to make it like an OS where each user has his own settings and such would be to use if, else if
Ok I got a working system now. It is rather messy but it works for this since it will only contain three users.
[cpp]
if(username.equals(u1))
{
if(password.equals(p1)){
JOptionPane.showMessageDialog(null, "Correct");
}else{
JOptionPane.showMessageDialog(null, "InCorrect");
}
}
else if(username.equals(u2))
{
if(password.equals(p2)){
JOptionPane.showMessageDialog(null, "Correct");
}else{
JOptionPane.showMessageDialog(null, "InCorrect");
}
}
else if (username.equals(u3))
{
if(password.equals(p3)){
JOptionPane.showMessageDialog(null, "Correct");
}else{
JOptionPane.showMessageDialog(null, "InCorrect");
}
}
else
{
JOptionPane.showMessageDialog(null, "Wrong");
}
[/cpp]
The dialog boxes will later be replaced with some actual useful stuff.

Oh, that seems a lot easier and less typing. Using that it will only check if there is a set? as in u1 has p1. Meaning if u2 types in p3 it won't work?

Well i havent actually tried it so dont take my word but it should only do the code if say:
U1 && P1 are correct, so if you enter U2 and P3 then it shouldnt work

In my opinion his current approach is overcomplicated, but of course easier to understand.
In Java this could be done with HashMap<String, String> for example:
[code]
// Untested code below written straight into reply box.
HashMap<String,String> users = new HashMap<String,String>();
public boolean CredCheck (String username, String password)
{
boolean success = false;
if (users.containsKey(username))
{
String correctpass = (String) users.get(username);
if (password.equals(correctpass))
{
success = true;
}
}
return success;
}
[/code]
And voila, you have support for as many users as you want. Use the [URL=http://download.oracle.com/javase/1.4.2/docs/api/java/util/HashMap.html#put(java.lang.Object, java.lang.Object)]put[/URL] method to put your users in the map.

You can make such systems much more secure if you don't return which was incorrect: the username or the password.

I didn't?
So a friend of mine told me he can draw pretty good and he wanted to make some games, so he bought a cheap tablet, got photoshop and I code.
We first decided to make a doodle-jump-thing to get into it or whatever, and:
[img]http://filesmelt.com/dl/jump.png[/img]
I mean, the background is kind of okay I guess, but what the hell is wrong with the player?
[img]http://filesmelt.com/dl/player123.png[/img]
:geno:
The top version is the image he gave me, no it's not scaled.
He also drew tim from braid:
[img_thumb]http://filesmelt.com/dl/braid.jpg[/img_thumb]
Plus he has weird design ideas. He made me program it so that you can wait on platforms and use space to jump.
What am I gonna do? I can't just tell him it sucks.
I hope he doesn't browse FP and finds this here. He'd be mightily pissed.

I have now spent 20 minutes trying to explain why I need the grass seperately (Because it's only on the ground) and why the background should be vertically tileable (It scrolls). He doesn't get it.
Behold; his interpretation of a tileable sky (I told him "They have to seamlessly connect top to bottom"):
