When you make a node, it has a range, if your node range is set to 1, you will definitely stand within 1 square of that node, for example:
Node 123, 123, 7
You might stand on any of these squares:
122, 122, 7
123, 122, 7
124, 122, 7
122, 123, 7
123, 123, 7
124, 123, 7
122, 124, 7
123, 124, 7
124, 124, 7
Or on a map it might look like this:
Code:
XXXXX
XOOOX
XONOX
XOOOX
XXXXX
Where your Node is "N", you will definitely stand stand on at least one "N" or "O". If your node range is 2 would be like this:
Code:
XXXXXXX
XOOOOOX
XOOOOOX
XOONOOX
XOOOOOX
XOOOOOX
XXXXXXX
Nodes are safer than stands, because they are more variable and do not create such strong patterns.
