Problems defining an array
« on: Apr 3rd, 2004, 1:26am » |

The following gives an "unexpected {" error on the "kernel = {" line... (please forgive formatting errors)
Code:int[][] kernel;
void setup() {
...
kernel = { /* Top, Left */ { (1), (width), (width + 1) },
/* Top */ { (-1), (1), (width - 1), (width), (width + 1) },
/* Top, Right */ { (-1), (width - 1), (width) },
/* Left */ { (-width), (-width + 1), (1), (width), (width + 1) },
/* Center */ { (-width - 1), (-width), (-width + 1), (-1), (1), (width - 1), (width), (width + 1) },
/* Right */ { (-width - 1), (-width), (-1), (width - 1), (width) },
/* Bottom, Left */ { (-width), (-width + 1), (1) },
/* Bottom */ { (-width - 1), (-width), (-width + 1), (-1), (1) },
/* Bottom, Right */ { (-width - 1), (-width), (-1) } };

it's because that's not legal syntax in java, unfortunately. if you want to assign arrays using { and }, it has to be done when the thing array is declared, ie:
int[][] kernel = { .. your stuff here .. }
unfortunately you'll ahve to use a constant for the width & height since those variables won't exist (or they'll just be zero, rather.. or maybe 100) until you're inside of setup().
