Solved Rainbow name?

I was wondering, how would I go about making someones name rainbow. Would I get each letter and color then set there name?

 

You should use player.setDisplayName(colorfulname);

 

Thanks for trying to help but..... How would you define colorfulname?

 

It is a string. I already coded what you asked for. Your choice now; I can show you pieces to help you do it yourself, or if you learn by seeing code I can just give it to you.


Below is the code... I'll help you get there yourself if you want, otherwise just read this and let me know. It should work.

Code:java

 
public String colorfulize(String in) {
ArrayList<String> chars = new ArrayList<String>(Arrays.asList(in.split("(?!^)")));
ArrayList<ChatColor> colors = new ArrayList<ChatColor>();
colors.add(ChatColor.AQUA);
colors.add(ChatColor.BLACK);
colors.add(ChatColor.BLUE);
colors.add(ChatColor.DARK_AQUA);
colors.add(ChatColor.DARK_BLUE);
colors.add(ChatColor.DARK_GRAY);
colors.add(ChatColor.DARK_GREEN);
colors.add(ChatColor.DARK_PURPLE);
colors.add(ChatColor.DARK_RED);
colors.add(ChatColor.GOLD);
colors.add(ChatColor.GRAY);
colors.add(ChatColor.GREEN);
colors.add(ChatColor.LIGHT_PURPLE);
colors.add(ChatColor.RED);
int c = 0;
String out = "";
for(String s : chars) {
out+=colors.get(c)+s;
c++;
if(c>=colors.size()) {
c=0;
Collections.shuffle(colors);
}
}
return out;
}
 

Implemented:

Code:java

 
player.setDisplayName(colorfulize(player.getName));
 

Hope you learn something! If you don't understand something I did, don't be afraid to ask.

Ok tested. It works fine.

 

Thanks your awesome! +1

 

Thanks! Glad I could help!

 

MeRPG Please don't spoonfeed code (and not so efficient code at that)

You see, I put it in the spoiler to give the option. Personally I learn from reading code (I learned configurations from your Pyromania), so simpler tasks such as that can be learned by reading it. If someone wants to code but doesn't want to learn, it is a shame. But no reason to make absolute sure someone won't copy/paste it. And honestly, it's efficiency isn't that bad. Only 1299452 nanoseconds, or ~1.3 milliseconds (for a 16 character input).

 

MeRPG that means that with about 50 players messaging in one tick, you are guaranteed to have TPS drop .

 

Hrm. That assumes that you are making the name colorful every time a player sends the message. I sure hope that is not the case. If it is, yes, the code is definitely too inefficient for that

Wait... Even if that was the case... 0.025989 ticks to handle that... So a 0.129945% drop in TPS.

 

instead of an ArrayList and shuffling it use a ChatColor[] and use Random.nextInt(array.length) to get a random ChatColr from the array and to .toCharArray() for the input string and iterate with that

 

that way would increase the chances of the same colors being adjacent. significantly. though you are right that an array should be used (less memory and more efficiency)

 

MeRPG there is a very simple way to prevent the same colour being used twice in a row.

Code:java

function random(n, previous)
{
    next = random.nextInt(n - 1);
    return next >= previous ? next + 1 : next;
}

This pseudo code basically takes a random number between 0 and n - 1, while excluding the previous number.

 

Yea I know what it does... That could work fine.
