Opening a workbench

I've been developing my own plugin for a while now, and now I've come to making commands just for efficiency. However, I've come across a dilemma when trying to open a Workbench with a command, each time, no matter what method I use I always get told that there is an error...

Here is the code that I am using:

public boolean onCommand(CommandSender command, Command sender, String label,
String[] args) {

Player player = (Player) sender;

player.openWorkbench(null, true);
return false;


In case if you are wondering, the command is simply /workbench.

Does anyone know how to fix this??!

 

@UnpeeledBanana1, few things.

Check if the sender is a player before casting.
Double check the documentation for openWorkbench and post the stack trace.

 

@Tecno_Wizard Well now a feel like an idiot... Thanks!

 

@UnpeeledBanana1 You have to put the player location i think, not null

 

@caderape it doesn't matter, player.openWorkbench(null, true); works just as well as it should do.

 

@caderape

If the location is null, by default it uses the player location.

 

Remember to put the Command in your plugin.yml.
And where did you check if the command is /workbench?
And you have a strange naming.
You cannot cast sender to Player because sender is a string containg the Command, and Command is actually your sender.

Code:

public boolean onCommand(CommandSender command, Command sender, String label, String[] args)

Then in the code you say

Code:

Player player = (Player)sender; 

But sender is the Command! Your CommandSender is called command!
I'd recommend to rename the Variables, to a more logical naming:

Code:

public boolean onCommand(CommandSendersender, Command command, String label, String[] args) 

Now sender is the CommandSender and command is a String containing the command. Your code swapped that which causes its Errors.
So now

Code:

Player player = (Player) sender; 

works, but remember to check if the sender is a player!
Then you can check if command is /workbench and then display the workbench.
