Any help whatsoever is much appreciated!

Much thanks in advance - DeGambler

 

its throwing a nullPointerException and by the looks of it

Code:java

 
if (config.getboolean("useVault"))
 

is the cause of the error. perhaps you forgot to set the boolean in the config or the capatilization is different etc.

 

Is the transactionSucess() method returning a Boolean? DeGambler

 

thecrystalflame Well, heres my config, should all be correct but I might be wrong:

Show Spoiler Hide Spoiler

Code:

useVault: true #If you aren't using vault, change to false
moneyGiven: 10.0 #Default value change to whatever you want
 
Diamondmsg: "You were given a diamond for logging in!"
Diamondamount: 1 #Set this to the amount of diamonds you want given upon login
 
GApplemsg: "You were given a diamond for logging in!"
GAppleamount: 1 #Set this to the amount of Gold apples you want given upon login
 
GoldIngotmsg: "You were given a gold ingot for logging in!"
GoldIngotamount: 1 #Set this to the amount of gold ingots you want given upon logging in
 
NormalApplemsg: "You were given an apple for logging in!"
NormalAppleamount: 1 #Set this to the amount of apples you want given upon login
 
Cakemsg: "You were given a cake for logging in!"
Cakeamount: 1 #Set this to the amount of cake you want given upon login

inventorman101 It should be...

 

Try ckecking if get transaction is true rather than checking if it is not DeGambler

 

DeGambler
hmm no that is correct. but somewhere in your deliverMoney method has a null value where it shouldnt
if i were you i would add debug lines to single out the cause.

 

Looks like you forgot to initialize the variable config.

 

hapm thecrystalflame inventorman101 Nothing I changed seems to have fixed it, heres the full project if you want to take a look at that, might find it there, other then that thanks a lot for the help!
