Set Players Velocity for Parachute Effect

Hello,

How would I go about setting a players velocity to create a Parachute effect? I've done all the Checking if player is falling, even setting their Y velocity, but I want to set their X or Z to whatever direction they're looking at. So they'll fall, and slowly move in whatever direction they are facing.

 

I would expect this to cause some problems, because gravity and falling is rendered client-side.

But here you go:

Code:java

// Change the 1 to whatever you need, because 1 might be too strong
player.setVelocity(new Vector(player.getVelocity().getX(), 1, player.getVelocity().getZ());

 

Thanks, but it's just affecting my Y, my X and Z stay the same no matter where I look

 

Normally this keeps the current X and Z velocity, but like I said this might be a bit glitchy, because it's rendered client-side.

I'm doing some testing on my own server and will be back soon with results.

 

Yup, I fall like I'm having a seizure or something

 

Ok, I've coded a nice litte plugin that works perfectly on my localhost server - so a little bumping in online servers will be normal.

Parachute.java

Code:java

public class Parachute extends JavaPlugin {
    private static Plugin instance;
 
    // Saves the runnable tasks and also signals if a player has parachute active
    private static Map<String, Integer> parachuteMap = new HashMap<String, Integer>();
 
    @Override
    public void onEnable() {
        instance = this;
        Bukkit.getPluginManager().registerEvents(new ParachuteListener(), this);
    }
 
    @Override
    public void onDisable() {
        // Making sure every task is cancelled and deleted ... even if it's not necessary :D
 
        for (int id : parachuteMap.values()) {
            Bukkit.getScheduler().cancelTask(id);
        }
 
        parachuteMap.clear();
    }
 
    public static Plugin getInstance() {
        return instance;
    }
 
    // Static call from ParachuteListener's PlayerInteractEvent handler
    public static void onPlayerInteract(PlayerInteractEvent e) {
        // Checking right click
        if (e.getAction().equals(Action.RIGHT_CLICK_AIR) || e.getAction().equals(Action.RIGHT_CLICK_BLOCK)) {
            // Checking for a specific item... I used blaze rod for testing
            if (e.getPlayer().getItemInHand().getType().equals(Material.BLAZE_ROD)) {
                // Create final Player variable which could be needed in Runnable (thats why it's final)
                final Player player = e.getPlayer();
                // Checking the map for an existing entry (means parachute is already active)
                if (parachuteMap.containsKey(player.getName())) {
                    // Cancel task and remove player from map (means parachute effect will not be active any longer)
                    Bukkit.getScheduler().cancelTask(parachuteMap.get(player.getName()));
                    parachuteMap.remove(player.getName());
                } else {
                    // Player had parachute not active so we create an entry in the map
                    parachuteMap.put(player.getName(),
                        // If you did not know: scheduling a task returns an integer, that's why we could write it directly into the .put()
                        Bukkit.getScheduler().scheduleSyncRepeatingTask(getInstance(), new BukkitRunnable() {
                            @Override
                            public void run() {
                                // Check if players is even online (because it's a final variable)
                                if (player.isOnline()) {
                                    // Check if the player is over an specific speed 0 = "zero gravity", 0.0001 = DAMN SLOW fall, 0.1 = very slow fall, 0.2 = slow fall ... and so on
                                    if (player.getVelocity().getY() < -0.2) {
                                        // Keep X and Z movement of the player and dampen his fall in a smooth way
                                        player.setVelocity(new Vector(player.getVelocity().getX(), player.getVelocity().getY()/1.25, player.getVelocity().getZ()));
                                        // Don't forget to reduce fall distance as well or else, even if the player is falling slow he will crush on the floor with a 32 block or so
                                        player.setFallDistance(player.getFallDistance()/1.25F);
                                    // Checks if the player is too slow for a parachute (if he only jumps 1 block)
                                    } else if (player.getVelocity().getY() > -0.15) {
                                        // Remove his parachute immediately
                                        Bukkit.getScheduler().cancelTask(parachuteMap.get(player.getName()));
                                        parachuteMap.remove(player.getName());
                                    }
                                // If player is not online
                                } else {
                                    // Remove his entries
                                    Bukkit.getScheduler().cancelTask(parachuteMap.get(player.getName()));
                                    parachuteMap.remove(player.getName());
                                }
                            }
                        }, 0L, 0L)
                    );
                }
            }
        }
    }
}

ParachuteListener.java

Code:java

public class ParachuteListener implements Listener {
 
    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent e) {
        Parachute.onPlayerInteract(e);
    }
}

 

Thank you, I appreciate it

I can work with this
