Re: [omnetpp] Random node placements

[Daniel Willkomm <willkomm at xxx>]

Hi 
this is rather a bug than a feature.
We assume that if you set either x or y to -1, a random placement is desired. 

However it should be easy to change that. You just need to modify the 
respective code in BasicMobility.cc
initialize and getRandomPosition are the functions you want to look at

Hope this helps

Daniel
