World.CreateExplosion - Invalid usage?

Hello everyone,

I try to make a visual explosion by using :

But it gives me :

How do I fix that?

Instead of using the World Object, use the world you want to create the explosion in. Like this: player.getWorld().createExplosion(...);

 

Isn't working.

 

Try this:

Code:

Player p;
 
if(sender instanceof Player) {
    p = (Player) sender;
} else {
    //Error
}
 
p.getWorld().createExplosion(p.getLocation(), 0.0F);

 

With explosion power 0.0F it can't work... Simply do this:

Code:

if(sender instanceof Player) {
    Player player = (Player) sender;
    player.getWorld().createExplosion(player.getLocation(), 4);
}

 

i wasn't aware that sender was an interface for player...

I think you should be more like this (from memory):

Code:

Player player = getServer().getPlayer(sender.getName());
 
if (player instanceof Player)  player.getWorld().createExplosion(player.getLocation(), 4);

 

Code:

sender.getPlayer();

???

Code:

player instanceof Player

???

1. 0.0F for explosion power gives off the smoke/sound effect but doesn't damage blocks.

1. sender.getPlayer() is completely wrong.
2. sender can be an instance of Player, and then casted to Player if it is.

 

Yea I was going from memory.. i forgot the pattern I use..

was thinking.


Player player = getServer().getPlayer(sender.getName());

then the instance check...

now that I know that sender can be a instance of Player already.. thanks... save me a step.

(edited my above post to be correct code of the same concept, although I do agree with the above now)

 

JDigital1337, actually if (player instanceof Player) will always return true, since player is a Player object. You need to check if player != null instead.

 

Worked. Thanks

 

that block of code is kinda bad, here fixed it up for you:

Code:

 
if(sender instanceof Player) {
  Player p = (Player) sender;
  p.getWorld().createExplosion(p.getLocation(), 0.0F);
} else {
//Error
}
