Thread: Why doesnt this logical tile loading system not work as I a begginer expect it to and many others for that matter?

Hello This is for a Java game

Why does this system only draw portions of tiles, it looks as if it only ever iterates a couple times
and doesn't iterate to load the entire map even though my txt file images\map.txt has something like.

1 1 1 1 1 1 1 2 2 2 1 1 3 4 1 1 1 1 2 3 ect.


please take a look at the sample.jpg I,ve attached.

I don't understand Ive spent a couple days now trying to load a full map.



This is my method of loading a java game map at run time.
Please help Thankyou.
