Check out the section from the DirectRT user's guide on "Using Random Values" or online here: http://www.empirisoft.com/directrt/h...dom_values.htm
Since you do not want overlapping, you may wish to limit the random locations to specific values. You can do this by specifying an explicit list of x,y values to choose from or by specifying defined ranges from which to pick the values.
example of location value:
rand(100-500),rand(200,800),0
which could produce, e.g., 343,655,0 as a LOC value.
or
rand(100,200,350),rand(200,300,800),0
which could produce, e.g., 200,800,0 as a LOC value.
