Causing a player to look like they took damage?

I can only think of one way, which is this:

Code:

	    	if(player.getHealth() == 20) {
	    		player.setHealth(19);
	    		player.setHealth(20);
	    	} else {
	    		player.setHealth(player.getHealth() + 1);
	    		player.setHealth(player.getHealth() - 1);
	    	}

but I doubt this is the best way on doing so. any recommendations?

 

That actually doesn't make them look like they took damage, just changes the value quietly.

 

really? I thought if you changed it to less than the health that they had would, but must've been mistaken.

anyway, does anyone know of a way to do this then?

 

Find the spot where the server handles dealing damage in the net.minecraft server sources. Activate the event.

 

@fullwall Hm? I don't really understand how to do that.

 

I assume we're talking about the little jerk and the flashing hearts you get when you get dealt damage?

If so:

Code:

CraftPlayer cPlayer = (CraftPlayer)thePlayer;
cPlayer.getHandle().a.b(new Packet8UpdateHealth(19));
cPlayer.getHandle().a.b(new Packet8UpdateHealth(20));

(adjusting numbers appropriately)

I just tested that and it works very well (though nobody else can see it except the player being hurt)

 

@Edward Hand the little jerk happens even with setHealth(), I want to be able to make mobs/players look like they've taken damage to other players.

 

In that case its a little more complex (but still possible):

Code:

CraftPlayer cp = (CraftPlayer)aRandomPlayer;
cp.getHandle().a.b(new Packet38EntityStatus(damagedPlayer.getEntityId(), (byte)2));

where damagedPlayer is the player being damaged and aRandomPlayer is the player you want to see that person being damaged. If you want the player to appear damaged to all players, do some kind of for loop.

 

thanks, this is what I needed

 

Oh and try changing that 2(byte) to 3(byte).

It makes it look like they died (resulting in instant invisibility for that player)

 

Hmm, bukkit isn't recognizing CraftPlayer
Whats the import for that?

 

You need to include a reverence to CraftBukkit-0.0.10-SNAPSHOT in eclipse or whatever (along with bukkit)

 

you need to add the craftbukkit library to your project, then it's this:

Code:

import org.bukkit.craftbukkit.entity.CraftPlayer;

edit:
ninja'd

 

Thanks, this is super helpful

Hmm changing the byte to 3 won't make monsters look like they've died.

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

 

You cast is a byte didnt you?
(byte)3
and you're sending the packet to the right player?

 

@Edward Hand
I am, I have two functions setup. One to make entities look like they've died and one to make them look like they've taken damage. It doesn't seem to be working for either case.

Code:

    public void sendDamagedLookPackets(Entity damaged){
        for(Player x : plugin.getServer().getOnlinePlayers()){
        CraftPlayer cp = (CraftPlayer)x;
        if(x.getEntityId() != damaged.getEntityId())
        cp.getHandle().a.b(new Packet38EntityStatus(damaged.getEntityId(), (byte)2));
        }
    }
    public void sendDeathLookPackets(Entity damaged){
        for(Player x : plugin.getServer().getOnlinePlayers()){
        CraftPlayer cp = (CraftPlayer)x;
        if(x.getEntityId() != damaged.getEntityId())
        cp.getHandle().a.b(new Packet38EntityStatus(damaged.getEntityId(), (byte)3));
        }
    }
