Solved Launch a block with a vector

I have been thinking of how do launch a web block with a vector so it looks something like this:



At 0:40

I tried to google but I didn't really find much. I was thinking of using LibsDisguises to launch an entity with the vector and disguising it as a block, but I don't know if that is possible with LibsDisguises. I would greatly appreciate any suggestions.

Thank you

 

@TheNewTao
You just spawn in a falling block (and set the type to spiderweb) then you can set the velocity (fallingBlock.setVelocity).

 

@Hawktasard

A spiderweb can be a falling block?

 

@TheNewTao any block type can be a falling block.

 

@TheNewTao Here, I had written this a long time ago. You may have this
It throws a cobweb item and when it hits the ground it gets rid of the item and puts down a cobweb.

Code:

public class Trapper extends JavaPlugin implements Listener {
   
   
    Trapper plugin;
    //Getting cobweb on ground scheduler
    int getCobwebOnGround;
    //Where cooldowns are stored
    public HashMap<String, Long> cooldowns = new HashMap<String, Long>();
    //Cooldown times. Could easily be replaced with a double for decimal numbers
    int cooldownTime = 10;

   
  
   
        public Trapper getPlugin(){
            //Instantiating plugin
            return plugin;
           
        }
  
   
        public void onEnable(){
           
           
            getServer().getPluginManager().registerEvents(this, this);
       
        }
   
        public void onDisable(){
            //Prevents memory leaks on disable
           
        }
       
       
        
       
       
       
       
        //Make sure the player cannot PLACE cobwebs
        @EventHandler
        public void onBlockPlaceAttempt(BlockPlaceEvent e){
            Player p = e.getPlayer();
            if(!p.isOp()){
            if(e.getBlockPlaced() == new ItemStack(Material.WEB)){
                e.setCancelled(true);
            }
            else{
                //Well, if the placed block isn't a cobweb, then you shouldn't have to do anything!
                }
            }
        }
       
        //If a trapped player can just break out then what's the point of this kit?
        //A player would most likely be too busy getting beat up / defending themselves to escape, anyways
        @EventHandler
        public void onBlockBreakAttempt(BlockBreakEvent e){
            if(!e.getPlayer().isOp()){
            if(e.getBlock() == new ItemStack(Material.WEB)){
                e.setCancelled(true);
            }
            else{
                }
            }
        }

I appreciate your code, but you are using an ItemStack. I want to launch an actual cobweb block. I'll try spawning a falling block and see if it works.
