start at 0 or 1

clankill3r

The line has 3 segments:

Let's say I have a method

float length(int segment) {
  // returns length of segment
}

Then should I start counting at 0 (like 0,1,2)? Or start at 1 (1,2,3)?

Generally I would suggest that you start at 0 since the first element in ANY sequential Java collection or array is zero.

For a more informative answer you might explain how are you storing the segment data e.g. an array of vertices, or a class to hold segment data or something else.

length is 3. but if the lines are numbered they are lines 0, 1, 2.

koogs

but what is 'segment' argument for?

clankill3r

thx zero it is.

segment, is what part of the line you mean.
