Thread: Help with an object based level format

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
at stringtest.main.Main.readHeader(Main.java:70)

Look at line 70 in your program for the error. The error message says you are trying to index the second element in an array that does not have 2 elements.

How are you using the split() method? Do you want to split the parts of the String at spaces between the numbers?
If so, use a single space in quotes: " " as the arg to the split() method.

For debug, print out the contents of the array created by split(). Use the Arrays class's toString() method to format the array for printing.

Changing "s1" to a space fixes the out of bounds error, but when I try to run now, I get these errors

Exception in thread "main" java.lang.NumberFormatException: For input string: "2 1 1"
at java.lang.NumberFormatException.forInputString(Unk nown Source)
at java.lang.Integer.parseInt(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)
at stringtest.main.Main.<init>(Main.java:29)
at stringtest.main.Jframe.main(Jframe.java:15)

What is the arg to parseInt() where the error occurs? (line 29)
The error message says it is the String: "2 1 1"
A String with non-digits in it can NOT be parsed to an int.

For debug:
print out the value of the line after you read it in
and also print out the contents of the array that the split() method returns.

The problem must be with the split into the array. I tried using " " as the split like was said, but its not working. The arg for parse int is the array to which the string should be splitting.

Well, changing hasNextLine and nextLine to hasNextInt and nextInt respectively doesn't work and still gives me an error. Removing the lines that set the string and array and setting the ints in the file to integers directly will at least run, but my draw method I'm using to test doesn't show (apparantly the ints don't equal what they're supposed to...) anyway to show what each int has directly on screen?

Can you post the code that you are having problems with?
Also post the full text of the error message and the contents of the file that you are trying to read.

Alright, I think its best if we go at this completely fresh. Alright, so I've changed my code up a bit so the file is actually read though the main JPanel. Here is the ENTIRE code for it:

//These import lines assure that all needed Java files are imported into the game.
//The "*"s tell the game to import the entire package of files.

Look closely to this code. This code is a very simple implementation of how i would do it.

1 20 40
2 40 30

First is the object id, second and third position. Now you need to change the object id to read the first 2 strings and check if it is a groundTileAtTop or something else, And try adding dynamic arguments.

Thanks elamre! Now I have the game reading from the file! (Sorry for the late reply, my internet was down for a couple of days...) If I have any trouble getting the game to spawn the appropriate objects, I'll let you know.

Yep, I'm having trouble again. I can only get the game to draw the last object of the file.
