So I have a Minecraft plugin called JustExplode, and I'm trying to make it so that if someone has the permission justexplode.timer, they have to wait 10 minutes before they can use the command /explode again. It doesn't work, I have tried multiple ways, and I'm new to programming....can someone help me? Here is my main class JustExplode.java:
package me.sam1370.justexplode;

saveConfig();
}

getLogger().info("JustExplode has been disabled!");
}

if (cmd.getName().equalsIgnoreCase("explode") && sender.hasPermission("justexplode.explode")){
// Make sure that the player specified exactly one argument (the name of the player to exPLODE!).
if (args.length != 1) {
// When onCommand() returns false, the help message associated with that command is displayed.
return false;
}
// Make sure the sender is a player.
if (!(sender instanceof Player)) {
sender.sendMessage(ChatColor.RED + "Only players can explode other players.");
return true;
}
// Get the player who should be exploded. Remember that indices start with 0, not 1.

And here is my config.yml that I set up:
# Default config file for JustExplode, by Sam1370
# There isn't a reload config command for right now, just reload or restart the server
# Change this to the message you want to see when you are exploding a player
# Put %player% in it to get the player that you are exploding
# Color codes are now supported, as opposed to version 1.0.8.2. YES!!!
message: "&aExploded &c%player%!"
# Change this to the message you want to see when a player tries to do /explode with the permission justexplode.timer
# Put %timeleft% in it to get the time left before they can explode again
# Color codes are supported
timer: "You can't explode anyone for %timeleft%!"
# Specify how many minutes, in milliseconds, how long you want someone to wait before they can do /explode again
# The default is 600000 milliseconds, which is 10 minutes
timerMinutes: 600000
Anyone know how to do this? Thanks in advance.
For these types of delays you need to use System.currentTimeMillis()and a simple HashMap
It's actually pretty easy, let me show you an example i wrote few weeks ago.
private static HashMap<CommandSender, Long> lastExplodeUses = new HashMap<>();
public static HashMap<CommandSender, Long> getLastExplodeUses() {
return lastExplodeUses;
}
public static void setLastExplodeUse(CommandSender player, long till) {
lastHelpopSended.put(player, till);
}
public static boolean canExplode(CommandSender player) {
long timeExploded = lastExplodeUses.get(player) == null ? 0 : lastExplodeUses.get(player);
if (timeExploded == 0) return true; // if it's 0 - you can execute explode command.
long timeCurrent = System.currentTimeMillis(); // current time in millis
if (timeExploded < timeCurrent) { // if the timeExploded is lower than timeCurrent you can execude explode command.
return true;
}
return false; // if not, you cant.
}
What next? You need to add to your command a few functions.
if (sender.hasPermission("justexplode.timer")) { // if player has permission, if not - bypass the timer.
if (!canExplode(sender)) {
// you can't explode yet :/
return;
}
setLastExplodeUse(sender, System.currentTimeMillis() + 10 * 1000); // set the till time to explode use. Current time + 10000, 10000 = 10 seconds.
}
// there you can do your explosion etc.
Remember! If you're creating for example kits when the delays are about 24 hours long, you need to save that HashMap to MySQL or somewhere else and load on start!
