%something% to text

Hi, I am creating a plugin. and I saw that some plugin are using %something% to put data or text.
for exemple:
message: player team is %myplugin_something%
and when you go in game it replace it by his team or something else
If anyone could tell me how to do it I would be very happy ^^

oh thanks ^^

@CraftCreeper6 sorry to mention you but I tryied the replace method but I just didn't knew where I had to place it to make it relace %something% to some text in any message that contains it. if you could help me I would be really happy ^^

You use the method on the String whatever string.replace("%something%, other thing);

 

I know this method is not correct but i don't know how I could use it :/ sorry to ask many question but I just want to make sure the plugin works correctly ^^

Code:

public String replace(CharSequence target,CharSequence replacement)
    {
        return (String) replacement;
    }

@EventHandler
    public void onChat(PlayerChatEvent e)
    {
        if(e.getPlayer() instanceof Player) {
            String msg = e.getMessage().replace("%snow_group_name%","GroupName");
            e.setCancelled(true);
            Bukkit.broadcastMessage(e.getPlayer() + msg);
        }
    }

if anyone could help me ^^

 

I think you are talking about placeHolders
you should use the PlaceHolderAPI some tutorials are explaining how to use PlaceHolderAPI

 

@cdnyassuo34
1. Use AsyncPlayerChatEvent instead of PlayerChatEvent.
2. You don't need to check if a Player is an instance of a Player.
3. You can use the AsyncPlayerChatEvent#setMessage(String message) method, instead of cancelling the event.

 

I think it is a good solution but is there anything that can just replace %something% to text ? instead of replacing all the message (to make it works with other chat plugins ^^)

 

@cdnyassuo34 Try setting the priority on the event to HIGHEST.

 

last question , is this the right use ? if yes would it replace %something% to text even if the %something% is used in the prefix (ex: %something% Snow : message) ?

Code (open) Code (close)

@EventHandler
public void placeHolders(AsyncPlayerChatEvent e)
{
String msg = e.getMessage();
msg.replaceAll("%snowclaim_groupname%", getGroupName(e.getPlayer()));
msg.replaceAll("%snowclaim_chunkcredit%", cc.get(e.getPlayer().getName()) + "");
msg.replaceAll("%snowclaim_snowdingerr%", "§0S§4n§co§6w§ed§ai§bn§9g§de§5r§1r");
msg.replaceAll("%snowclaim_groupname%", getChunkOwner(getPlayerChunkXZ(e.getPlayer())));
msg.replaceAll("%snowclaim_currentchunk%", e.getPlayer().getLocation().getChunk().getX() + "," + e.getPlayer().getLocation().getChunk().getZ());

e.setMessage(msg);
}

 

@cdnyassuo34 You are close, but not exactly.
1. You can use String#replace() instead of String#replaceAll() because you aren't using regex.
2. String#replace returns a new modified string, so you need to set 'msg' to that. Example:

Code:Java

msg = msg.replace(...);

 

oh ok ^^ thanks ^^
@KarimAKL (sorry to mention you :/)
Sorry to post many question and problems I have ^-^'
but I am using this code:

Code:

   @EventHandler (priority = EventPriority.HIGHEST)
    public void onChat(AsyncPlayerChatEvent e)
    {
        Player p = e.getPlayer();
        String currentc = e.getPlayer().getLocation().getChunk().getX() + "," + e.getPlayer().getLocation().getChunk().getZ();
        String ggn = getGroupName(e.getPlayer().getName());

        e.setFormat("%snowclaim_test% " + p.getName() + e.getMessage());
    
        e.getFormat().replace("%snowclaim_ggn%", ggn);
        e.getFormat().replace("%snowclaim_curc%", currentc);
        e.getFormat().replace("%snowclaim_cc%", cc.get(p.getName()) + "");
        e.getFormat().replace("%snowclaim_test%", "1234");
        e.getFormat().replace("%snowclaim_gco%", getChunkOwner(getPlayerChunkXZ(p)));
    }

and it returns me this error everytime I send a message in the chat. I know it's a thing with AsyncPlayerChatEvent
but I don't know how to fix it -_
