randomization???

how would you go about randomizing a set of methods?

for example these 3 messages get randomly picked:

player.sendMessage("hi");
player.sendMessage("sup");
player.sendMessage("hey");

its a bad way to example but thats the idea

 

take a look at this: http://www.cs.geneseo.edu/~baldwin/reference/random.html

 

Code:java

String[] greetings = {"hi", "sup", "hey"};
 
player.sendMessage(greetings[new Random().nextInt(greetings.length)]);
 
//or something similar ;D

 

i would chose this code!

 

thanks would this be able to go for any method?

 

Hopefully ;D

Depends what in particular you want but it should work with all Arrays

If you want a version with lists:

Code:java

List<String> greetings = new ArrayList<String>();
 
greetings.add("hi");
greetings.add("sup");
greetings.add("hey");
 
player.sendMessage(greetings.get(new Random().nextInt(greetings.size())));
 

 

Or you could do it the uneffecent way:

Code:

 
String hi = "hi";
String sup =  "sup";
String hey = "hey";
            int n = 1 + (int)(Math.random() * 3);
            if(n == 1){
                event.getPlayer().sendMessage(hi);
            }else if(n == 2){
                                event.getPlayer().sendMessage(sup);
            }else if(n == 3){
                event.getPlayer().sendMessage(hey)
            }
        }

 

any clue how i could go about "weighting" different ones so like "hi" has a better chance than "hey"

 

Add it in the array again.

 

Of you could use the Apache RandomUtils class, no need to make a new instance of Random.
Example:
return RandomUtils.nextInt(10) == 0;
//1 in 10 chance
