Check if Player is standing still.

@VNGC remove everything in the onlinePlayers loop except the broadcastMessage and see what velocity is for you in different scenarios while walking around in game. It should print your getVelocity.length every second if you do that.

Furthermore, if you can't code at all, this isn't the right section for you. Maybe try putting this in the plugin request section.

 

@Kars so only this?

Code:

 Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(this, new BukkitRunnable() {
            public void run() {
                for (Player player : Bukkit.getServer().getOnlinePlayers()) {
                Bukkit.broadcastMessage(""+player.getVelocity().length());                  
                }
            }
        }, 20L, 20L);        

 

Error occurred while enabling Challenges (Is it up to date?) java.lang.UnsupportedOperationException: Use BukkitRunnable#runTaskTimer(Plugin, long, long)

i tought it works if i add @SuppressWarnings("deprecation")

 

Code:

  Bukkit.getServer().getScheduler().runTaskTimer(this, new BukkitRunnable() {

aren't they there? doesnt looks wrong

 

in the console it says that its the fault of this line.

 

now working. but it is showing me in chat only the Y-Velocity i think? the value is only changing if i jump, not if running

 

@VNGC So you need to apply the method that i initially suggested.
Make a static variable that is able to store a players location. In the repeating task, if the variable is set, compare it to the players current location and if it is different, you will know that they have moved. After that, save the players current location to the static variable.

If you don't understand, that is fine. This is too big a task to assist with. Make a plugin request.

    public static Main getPlugin() {
        return plugin;    
    }
    @Override
    public void onDisable() {
        plugin =this;
     
    }

}

the only thing i edited now:
if(Command_MoveDamage.movedamage){
so i can turn it on/off.
