Spawning in a fishinghook when left clicking a certain item?

Ok guys so basically I want to make a grappler kit. I made it with a fishing rod, but I want to make It so when I left click a lead it shoots out a fishingrod bobber thingy please help me as much as you can! Thanks Here is my code so far:

Code:

ArrayList<String> grappler = new ArrayList<String>();
@EventHandler(priority=EventPriority.NORMAL, ignoreCancelled=true)     
public void onPlayerFish(PlayerFishEvent event)     
{        final Player player = event.getPlayer();         
if (event.getState().equals(PlayerFishEvent.State.IN_GROUND))       
{            Location lc = player.getLocation();           
Location to = event.getHook().getLocation();           
lc.setY(lc.getY() + 0.5D);           
player.teleport(lc);           
double g = -0.08D;           
double d = to.distance(lc);       
double t = d;         
double v_x = (1.0D + 0.07000000000000001D * t) * (to.getX() - lc.getX()) / t; 
double v_y = (1.0D + 0.03D * t) * (to.getY() - lc.getY()) / t - 0.5D * g * t;       
double v_z = (1.0D + 0.07000000000000001D * t) * (to.getZ() - lc.getZ()) / t;   
Vector v = player.getVelocity();            v.setX(v_x);            v.setY(v_y);            v.setZ(v_z);     
player.setVelocity(v);         
grappler.add(player.getName());              }
else if (event.getState().equals(PlayerFishEvent.State.CAUGHT_ENTITY))   
{            Location lc = player.getLocation();       
Location to = event.getHook().getLocation();           
lc.setY(lc.getY() + 0.5D);            player.teleport(lc);           
double g = -0.08D;            double d = to.distance(lc);         
double t = d;            double v_x = (1.0D + 0.07000000000000001D * t) * (to.getX() - lc.getX()) / t;     
double v_y = (1.0D + 0.03D * t) * (to.getY() - lc.getY()) / t - 0.5D * g * t;         
double v_z = (1.0D + 0.07000000000000001D * t) * (to.getZ() - lc.getZ()) / t;         
Vector v = player.getVelocity();            v.setX(v_x);            v.setY(v_y);            v.setZ(v_z); 
player.setVelocity(v);            this.grappler.add(player.getName());   
}
}

This isn't even your code ._. but regardless, try taking a look at this post:

Harmings What do you mean by

 

JRL1004 He said in his post "Here is my code so far" but that code was given out here:

Harmings What do you mean? I coded this by my self, I used that as a guide kinda.

 

'As a guide' I got you

 

JRL1004 Harmings With a little research of my own, I found out to spawn an entity. But for some reason it won't spawn the fishing hook when I left click the leash. Take a look. Its my (OWN) code:

Code:

@EventHandler
public void onGrapplerthingy(PlayerInteractEvent e){
    Player p = e.getPlayer();
    Action a = e.getAction();
    Vector vector = p.getEyeLocation().getDirection().multiply(3);
    List<Entity> nearbyEntities = p.getNearbyEntities(10, 10, 10);
    for(Entity entity : nearbyEntities){
        entity.setVelocity(vector);
        Entity hook = p.getWorld().spawnEntity(p.getEyeLocation(), EntityType.FISHING_HOOK);
        if(a == Action.LEFT_CLICK_BLOCK || a == Action.LEFT_CLICK_AIR && p.getItemInHand().getType() == Material.LEASH){
            hook.setVelocity(vector);
        }
    }
}

chasechocolate boysnnoco Could you help me? I am trying to spawn In a fishhook entity but it doesn't work. what is wrong with my code? Thanks

Code:

@EventHandler
public void onGrapplerthingy(PlayerInteractEvent e){
    Player p = e.getPlayer();
    Action a = e.getAction();
    if(grappler.contains(p.getName()) && p.getItemInHand().getType() == Material.LEASH){
        if(a == Action.LEFT_CLICK_AIR || a == Action.LEFT_CLICK_BLOCK){
    Vector vector = p.getEyeLocation().getDirection().multiply(3);
    p.getWorld().spawnEntity(p.getEyeLocation(), EntityType.FISHING_HOOK);
    List<Entity> nearbyEntities = p.getNearbyEntities(1, 1, 1);
    for(Entity entity : nearbyEntities){
            entity.setVelocity(vector);
    }
    }
}
}

TheAnswerIsMinecraft you have to change nms code in the Fishing hooks class. there is a void h() that you must override. it has a checker that makes sure you have a fishing rod in your hand. i spent hours looking at that obfuscated code and i figured it out and finally got everything working.
