Hi, I want to be able to read a list of predefined x positions into a two dimensional array, the x relating to the horizontal position of an object. Is it possible to read these in from an external text file or will I have to hard code them. Thanks for any help. nowan

Ugh, sorry, not a two dimensional array a ''one'' dimensional array.

yeah, use java.io.BufferedReader to read files, the argument in the constructor should be a new FileReader with the argument for that constructor being the filename. However you will need a way to figure out how big to make the array. You can either read it in first or read into a Vector and get an array out of that.
