Array Index is out of Range

Hi All

I have an error that i stumbled across. The error is Index Out of Range Exception: Array Index is out of range.
Below is the code


for(int rowIndex = 0; rowIndex < currentRoom.Length + 1; rowIndex++)
{

string layoutRow = layoutRows[rowIndex].Trim('\t'); //Error here
int numTiles = layoutRow.Length;

for(int i = 0; i < numTiles; i++)
{
AddTile(layoutRow, rowIndex, i);
}
}


I didnt understand what the error is or how to solve it. Can anyone help me please?

Thanks

 

It means that you are trying to use an array index that does not exist. Note that arrays start from index 0.

 

First line should PROBABLY be:

Code (csharp):

1. for(int rowIndex = 0; rowIndex < currentRoom.Length; rowIndex++)

This is assuming that currentRoom and layoutRows are the same length...

 

It is complaining about this piece: int numTiles = layoutRow.Length;

 

Complaining how? You need to post the actual error for people to help you.

 

I would guess that the first for loop should be;

Code (CSharp):

1. for (int rowIndex = 0; rowIndex < layoutRows.Length; rowIndex++)

 

Forgive me. Here is the error.

 

Im pretty sure its .Count not .Length, also dont add 1 to your length, if it is length then thats why your going over your array.

 

This line: "int numTiles = layoutRow.Length;" can not generate that error. I'd guess it's still coming from the line before that line, like in your original post. It's hard to know what the issue is without knowing what any of these variables mean, but if my fix didn't work, then maybe WarmedxMints is correct:

Code (csharp):

1. for (int rowIndex = 0; rowIndex < layoutRows.Length; rowIndex++)

Index out of range means that "rowIndex" is a number outside the length of the array. If an array is length 3, then the only allowed index values are 0, 1, and 2. Anything 3 or higher will say "Index out of range."
