delay between messages

Hi

I am trying to make it so that when a player joins, it sends them a series of messages. the only thing is, between each message, I need a delay (a small one, maybe .25 seconds or so) Im not sure how to do this, and if the answer is Threads, could you point me in the direction of a good tutorial on this? I dont know how to use threads

I feel like that would be really helpful, But I dont understand what its trying to tell me D:

Bump? I really need this, and idk what that link is trying to tell me

Bump once every 24 hours.

It's telling you to create a delayed task that is run after a certain number of ticks to accomplish what you need.

OK, Sorry about bumping it again, I understood that, but I dont understand what its telling me to do to get to that point

Read the entire article, it explains that you must create a Runnable (for all intents and purposes, a section of code) to be run at a later time, and then to schedule it run delayed on the main thread. The article explains how to do all of that.

OK, Thank you for telling me to read it, I only read parts of it *facepalm*

I believe this is the code I need:

Code:java

 @EventHandler
public void onJoin(PlayerJoinEvent event) {
// Create the task anonymously and schedule to run it once, after 20 ticks
new BukkitRunnable() {
 
@Override
public void run() {
// What you want to schedule goes here
plugin.getServer().broadcastMessage(
"Welcome to Bukkit! Remember to read the documentation!");
}
 
}.runTaskLater(this.plugin, 20);
}

but could I make (in this case I need 7 different sets of messages sent) 7 of those? or put in a for loop that runs 7 times?

 

bobthefish

That depends, if the messages are sent one after the other, you could just send them all in the delayed task, however if they need to be sent at different times, you would need separate runnables for each. Although you could just schedule a repeating one that iterates over a list of messages if the delay between them is the same, and then just cancel it when it is finished.

I have 3 messages that are sent at the same time, and then those 3 are each sent 7 times in their groups of 3, so I should make 7 runnables?

I cant really repeat it, because they arent the same 3 messages each time

one other thing, how many ticks are in a second, ive heard 2, 4, 20 and even 50. Do you know the number?

But you could repeat it, if you iterate over a list.

Code:java

ArrayList <String> list = getConfig().getStringList("joinmessages");
 
Iterator iter = list.iterator();
new BukkitRunnable () {
    @Override
    public void run() {
      for(int i = 0; i <3; i++ ) {
        if(iter.hasNext()) {
          player.sendMessage(iter.next());
        }
        else {
          cancel();
          break;
        }
      }
    }
}.runTaskTimer(pluigin,0,delay);

A server running at full speed runs at 20 ticks per second, it may run slower if the server is overloaded, however.

Normally, 20. Can be fewer if the server is slow, due to longer time to calculate a tick. I'm interested where you heard 2, 4 and 50, though.

Edit: ninja'd *shakes fist at above post*

 

Necrodoom a while back I looked around a little bit for a redstone gadget, but got mixed answers, thanks for helping me mythbusterma, Ill try to repeat it!

 

That's because redstone ticks only happen at 10 ticks a second, rather than 20.

 

mythbusterma so I tried to repeat it, but couldnt quite get it, although I may have just thought of something, the other thing is though, I didnt repeat it, and put it all in a big line down my code but when logged on, it sent them all out of order :/

mythbusterma I got it to repeat, but in your repeating example, where it says "plugin,0,delay" down at the bottom what is the "o" for?

Show us the updated code OP

 

I figured it out! thanks you everyone for helping (mostly mythbusterma)
