8000 Milestone

wtswkz commented

When I try to run the osg-earth sample, I encountered the problem as shown in the following picture.

This error is throwed from a function called doubleValue in cvalue.cc. The function call trace is as follows:

It seems to be not allowed to assign a value that has unit to a dimensionless number.

I want to know if this is reasonable and how to solve this problem.

Let me reformulate the issue you seem to be having.

you have a NED parameter or parameters that have @unit, say double x @unit(m) and double y @unit(m), and
you want to use those values in the display string, e.g. like @display("p=$x,$y");, and
you CANNOT, because that causes the error shown above.
