Hello everyone I saw a lot of people asking questions about Signs! So I made a little tutorial about some basics with signs. I hope this helps! These are the subjects I am going to explain: Getting and setting lines. Sign click. Update signs Minigame join signs. Getting and setting lines: So for the absolute basics, we are going to make a SignChangeEvent. This is for example when someone creates a sign. so: Code: @EventHandler public void onSignChange(SignChangeEvent e) { if (e.getLine(0).equalsIgnoreCase("hi")) { //If on the first line (line 0 is the first line) on the sign is written: hi e.setLine(0, "hello"); //It will change the first line to "hi" e.setLine(1, "how"); //the second line to "how" e.setLine(2, "are"); //the third line to "are" e.setLine(3, you"); //the fourth line to "you" } } So when a player makes a sign with on the first line written: "hi" the sign will look like this: hello how are you You can play a bit with it, maybe use colors and stuff. Sign click: So we just made that the sign changes. Now we want to check if someone clicks that sign! For that, we are going to use a PlayerInteractEvent. A PlayerInteractEvent is not only for sign clicks, but for now we are going to use it like that. So: Code: @EventHandler public void onPlayerInteract94(PlayerInteractEvent e) { if (e.getAction() != Action.RIGHT_CLICK_BLOCK) return; //if the player right clicks a block if ((e.getClickedBlock().getState() instanceof Sign)) { //if it's a sign Sign s = (Sign)e.getClickedBlock().getState(); //defining the sign as the letter "s" if (s.getLine(0).equalsIgnoreCase("hello")) { //if the first line is "hello" (ignores capital letters.) e.getWhoClicked().sendMessage(ChatColor.GREEN + "hello!"); //e.getWhoClicked is the player that clicked the sign. //So, if someone clicks the sign with on the first line written: "hello" it'll send the player in green: "hello!" } } } So there you have it! You can now change a sign, get who clicked the sign and send that player a message! Update signs: So now we are making a really simple, but really important thing for making a minigame sign. We are now going to update the sign! We are first going to use the code from the Sign click. And then we are going to make a really simple sign update. Code: @EventHandler public void onPlayerInteract94(PlayerInteractEvent e) { if (e.getAction() != Action.RIGHT_CLICK_BLOCK) return; if ((e.getClickedBlock().getState() instanceof Sign)) { Sign s = (Sign)e.getClickedBlock().getState(); if (s.getLine(0).equalsIgnoreCase("hello")) { e.getWhoClicked().sendMessage(ChatColor.GREEN + "The sign will now be changed!"); s.setLine(0, "hi"); //we defined "s" as the sign that get clicked, and then we set the first line to "hi" s.update(); //this is the simple but important part, this will update the sign, without this, the sign won't change. } } } So there you have it! We are now only 1 step before making a minigame sign! The last step: Minigame join signs: If you want to make Minigame join signs, you gotta use all the steps we just did. So first, we are going to change the sign if it's created: Code: @EventHandler public void onSignChange(SignChangeEvent e) { if (e.getLine(0).equalsIgnoreCase("Minigame")) { //if the first line is "minigame" e.setLine(0, "[Minigame]"); //it'll set the first line to "[Minigame]" e.setLine(1, "nice map"); //it'll set the second line to "nice map" } } Now we want to make a number of players in there. So we are going to define an Int (a number). So on the top of our class, we are going to put this: Code: int number = 0; //we made an int named "number" and we made it 0 So now, we want to set the third line of the sign to that number. so: Code: int number = 0; @EventHandler public void onSignChange(SignChangeEvent e) { if (e.getLine(0).equalsIgnoreCase("Minigame")) { e.setLine(0, "[Minigame]"); e.setLine(1, "nice map"); e.setLine(2, number + "/8"); //sets the third line to number (now defined as 0) /8 } } The sign will now look like this: [Minigame] nice map 0/8 Note: If you wish to make the line only show the number, you should do: Code: e.setLine(2, number + ""); Because the line has to be a string. So now we got the sign. Now when someone clicks that sign, it should make it 1/8. Code: @EventHandler public void onPlayerInteract100(PlayerInteractEvent e) { if (e.getAction() != Action.RIGHT_CLICK_BLOCK) return; if ((e.getClickedBlock().getState() instanceof Sign)) { BlockState bs = e.getClickedBlock().getState(); //e.getClickedBlock is the block that got clicked. Sign s = (Sign) bs; //this time, we define the sign with a BlockState. if (s.getLine(1).equalsIgnoreCase("nice map")) { //if the second line is "nice map" if (number < 9) { //if the number is less then 9 number = number + 1; //adds 1 to the number if (number == 8) { //if number is exactly 8 number=0; //it sets the players back to 0 s.setLine(2, number + "/8"); //it sets the sign to that number (now 0) s.update(); //it updates the sign } else { //if it's more then 8 it doesn't have to do anything, because it's impossible. (if it's 8 it goes back to 0) } } } } } So this is our full code: Code: int number = 0; @EventHandler public void onSignChange(SignChangeEvent e) { if (e.getLine(0).equalsIgnoreCase("Minigame")) { e.setLine(0, "[Minigame]"); e.setLine(1, "nice map"); e.setLine(2, number + "/8"); //sets the third line to number (now defined as 0) /8 } } @EventHandler public void onPlayerInteract100(PlayerInteractEvent e) { if (e.getAction() != Action.RIGHT_CLICK_BLOCK) return; if ((e.getClickedBlock().getState() instanceof Sign)) { BlockState bs = e.getClickedBlock().getState(); //e.getClickedBlock is the block that got clicked. Sign s = (Sign) bs; //this time, we define the sign with a BlockState. if (s.getLine(1).equalsIgnoreCase("nice map")) { //if the second line is "nice map" if (number < 8) { //if the number is less then 8 number = number + 1; //adds 1 to the number s.setLine(2, number + "/8"); //it sets the sign to that number (now 0) s.update(); //it updates the sign if (number == 8) { //if number is exactly 8 number=0; //it sets the players back to 0 s.setLine(2, number + "/8"); //it sets the sign to that number (now 0) s.update(); //it updates the sign } else { //if it's more then 8 it doesn't have to do anything, because it's impossible. (if it's 8 it goes back to 0) } } } } } So now I am going to show you what happens, just by words (it's hard, but i'll give it a try). So a sign has been created with on line 0 written: minigame. The sign will change to: [Minigame] nice map 0/8 Now a player clicks it. The number is now less then 8, so it'll add 1 to number (it is now 1). A few other players clicked it, now the 8th player clickes the sign, number=8 now, it is less then 9, so it goes to where it equals 8. so it sets it back to 0 when the player clickes it. Then it updates the sign again. I hope this helpes some of you out! Those were some basics, so you can all start playing with making signs and minigames. Thanks for reading! if I made any mistakes, I would appreciate if someone tells me them, so I can make this tutorial better. The end! You can now make basic signs! Please leave a like and a nice comment if I helped you out!
Ouch You cannot check whether number equals 8 since you have checked whether it is smaller than 8 before. If it is smaller than 8 it will never equal 8 since that is taken care of.
@HenkDeKipGaming If it is anyway capped at 8 You could basically just replace it with if (true) since it will always be lower than 9 and we all know that if (true) can obviously be left out. So yeah and else if-statement would make more sense here...
oh so it has to open the sign gui and the player has to write his password... i'll research that, wait a moment
i think i found the same one. i actually have no idea how to do this xD it's interesting though. but why'd you want that? can't you use chat?
I made a post about it that doesn't use protocollib and uses reflections: http://bukkit.org/threads/open-signgui-with-packets-not-protocollib.359553/
I think this requires ProtocolLib ... I already tried it with the packet but no args, but the SignChangeEvent doesn't get called then
Hey, so when player joins the game, it adds 1 to "0/8", but how can I make that when player dies or when player leaves the arena it removes 1? Players can leave the arena doing /leave, or dying...
Have an arraylist or something to store the players who joined the game, on the PlayerDeathEvent or PlayerQuitEvent or when the players types /leave, set the sign line to yourArrayListOfPlayersWhoJoinedTheGame.size()+"/8"
Thank you are helping me, but I already fixed it. Now, I need, another thing... To join the arena, players have to click the sign, then they have to select a kit (its a kitpvp plugin) so, I dont want that when players click the sign, it adds 1 to 0/8, I want that when players select a kit, it adds 1 to 0/8... So, I created a HashMap for a list, when players select a kit, it adds the player to the hashmap, and adds 1 to the "0/8", when players die, or use the commands for leave, it checks if player is in the hashmap and then removes 1 of the "0/8", but I have one problem: When players click the sign, it uploads the sign, but I need that when players select the kit, uploads the sign. Sorry for bad english. Thanks.
