room list as an array in unity

Question

i am tryiing to get the room ids of the rooms that i created on the console to display as gui in my game. by default the listener script on calling the function ongetallroomsdone() displays the room ids as log using the code:-

Log ("onGetAllRoomsDone : " + eventObj.getResult());

for(int i=0; i< eventObj.getRoomIds().Length; ++i)

{

Log ("Room ID : " + eventObj.getRoomIds()[i]);

}

in order to display the list as GUI in my game i decided to create a string array k and assign the room ids to it in the loop and then display it.but when i make the following changes it stops after displaying the first room id in the log and the debug.log i put .please help!

 

public String[] k;

public void Start()

{
k=new string[20];

}

public void onGetAllRoomsDone (AllRoomsEvent eventObj)

{

 

Log ("onGetAllRoomsDone : " + eventObj.getResult());

for(int i=0; i< eventObj.getRoomIds().Length; ++i)

{

Log ("Room ID : " + eventObj.getRoomIds()[i]);

k[i-1]=eventObj.getRoomIds()[i];

}

 

}

 

Answer 1

k[i-1]=eventObj.getRoomIds()[i];

when you try to access item with index "i-1" you may try to access [-1] with i=0 . thus it should throw an error right there. Check whether you really want to access to the array member with index of "-1". therefore using ++i should not stop this from happening. My solution suggestions are:

1-) Check if an item exists prior to accessing it.

2-) Decide if you really need to access (i-1) th index in your for loop, if not change it so other elements get decent indexes such as :

for(int i=0; i< eventObj.getRoomIds().Length; i++)

{

Log ("Room ID : " + eventObj.getRoomIds()[i]);

k[i]=eventObj.getRoomIds()[i];

}
