an annoying problem

So I've been talking about the spectator arrow block. that still hasn't been fixed
but now if you stand in front of a player and he tries to place the block it doesn't works because I'm at the place he wants to place the block. is there any way to hide a player fully from everything
so no arrow block, no block glitch thing.
because you can hide an entity with packets but its still there you can still hit it, etc etc.

 

Check if someone places a block
Check if a spectator is in that block
Cancel event
Place the block
(i guess)

 

JordyPwner You can't check it with the place block event because the event doesn't even fire because you actually rightclick the player

 

Listen to entity interact - if get item in hand is a block? - place block at looking point

 

PlayerInteractEntityEvent

 

ChipDev Okay and the problem with the arrow?

 

Cancel arrowHitEvent?

 

ChipDev And how could I get the block where hes looking at because the get target block is a block but its actually air we are editing
and theres no arrowHitEvent

EntityDamageByEntityEvent

 

CraftCreeper6 It still isn't working I've done the arrow thing and it doesn't work

 

Funergy
EntityDamageByEntityEvent
Check if the damager is an arrow. Check if the damaged is a player. If they are both true then cancel then get the velocity of the arrow. Store it, when the arrow hits the player cancel the event to prevent them from taking damage, re-spawn the arrow with the same velocity (Use Arrow a = (Arrow) player.launchProjectile(Arrow.class); then use a.setVelocity(myArrowVelocity))

Done

 

CraftCreeper6 I'll check that out tommorow

 

codename_B ? You know how to fix these 2 problems?

 

CraftCreeper6
That didn't work for me. So what I need to fix now is the Arrow blocking
but fireblast709 helped me with answering someone that had the same problem (BlockCanBuildEvent)

 

Funergy Show the code that didn't work

Code:

if(e.getEntity() instanceof Player && e.getDamager() instanceof Arrow){
                Arrow r = (Arrow) e.getDamager();
                Player d = (Player) r.getShooter();
                Player p = (Player) e.getEntity();
                String ps = InGameHandler.getTeam(p);
                String ds = InGameHandler.getTeam(d);
                if(ps.equalsIgnoreCase(ds)){
                    e.setCancelled(true);
                    return;
                }
                if(SpectatorHandler.spectators.contains(p)){
                    Vector v = r.getVelocity();
                    e.setCancelled(true);
                    Arrow a = (Arrow) p.launchProjectile(Arrow.class);
                    a.setVelocity(v);
                }
            }

 

Funergy You never check the shooter is a player. Also, you don't move the spectator out of the way or anything, so surely it'll just keep on flying towards them and hitting them until one of the two move out of the way? Try teleporting the spector away somewhere, for example in the air a few blocks.

 

A better way to do this would be to move the arrow like half a block more back

 

xMrPoi I've found that that approach can lead to problems - for example, a spectator's hitbox may overlap with a player's enough that you completely miss someone by misfortune. It can happen more often than you'd think, especially since (in my experience) spectators have an annoying habit of trying to stand on top of players for some reason. It'll also open up to abuse if players work out they can make arrows miss in that fashion.

 

AdamQpzm But as you see on the hive network you can't spec block
and they don't teleport you

AdamQpzm Is there any way I get the location of the back of that player. so I can spawn the arrow at the back of him

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Funergy No, you'll have to add some to the location yourself.

 

Funergy they might just be overriding the arrows with their own custom class.

 

fireblast709 AdamQpzm Should I do if a player is in the radius of an arrow then we teleport them to another place?
I know I can use something like Location.distanceSquared() but how should I do that because theres no projectile move event. and If I do a bukkit runnable when the arrow gets shot and we check every 1 ticks if hes in that radius en then we teleport them, should lagg horribly because like someone is bow spamming.

 

Funergy Why do you need to do that? Just recreate the projectile if it hits a spectator.

 

AdamQpzm Should this work?

Code:

p.teleport(p.getLocation().add(0,5,0));
                    Vector v = r.getVelocity();
                    e.setCancelled(true);
                    Arrow a = (Arrow) p.getWorld().spawn(r.getLocation(),Arrow.class);
                    a.setShooter(d);
                    a.setVelocity(v);

 

Funergy I don't see why not, although you might want to set the spectators to flying (if they're allowed to fly) just because it looks better that way and keeps them out of the way for longer.

 

fireblast709 I don't think so, it's possible to make arrows go through players using NMS without overriding anything, you just need to set a boolean value in the EntityPlayer class

 

Konato_K for unknown reasons I completely read past that one. It's the 'isInvulnerable' field in PlayerAbilities btw.

 

You could always restrict the spectators from getting too close to other players.

 

fireblast709 Also the collidesWithEntities field, both work to make players not being hit by projectiles.
