I’ve encountered a weird issue
I created a C# component that was working fine when testing
but after saving the file, when opening the file again, the component causes crashes when enabled
When debuging, I commented out section by section and it all works
after uncommenting all the sections, the component works again
I can change all the inputs and it’s fine, but if I press Recompute or save, it’ll all crash again.
I don’t know why it’s cause crashes, can someone please check and let me know?
I’m on Version 6 SR31
(6.31.20315.17001, 11/10/2020)
Maybe I am confused, but it appears run is never set to false. Thus your while loop runs indefinitely. You might want to verify this block of code is correct, logically.
else if((possible && intersects.Count > 0) || !possible)
run = false; //if no intersection exit loop
}
I use the boolean possible to check if intersection in one direction is possible bool possible = Possible(crv, pln, dist);
First I test for below the plane, then above the plane
by commenting out the while loop and printing out the possible boolean
with the internalised values I get :
False (for below)
True (for above)
For intersections below the plane possible = false, so in the while loop, if there’s no intersections the !possible portion of the exit condition would be true, which then sets run to be false
For intersections above the plane possible = true, so since either/both start/end point of the curve is above the plane, there should be at least one intersection, the plane will continously move up in each iteration: pln.Origin = pln.Origin + (pln.Normal * dist);
at which point when an intersection happens, intersects.Count > 0
so after the intersection, if there’s a step when there’s no intersection possible = true and intersects.Count > 0 makes (possible && intersects.Count > 0) = true which allows for the exit run = false
I don’t think my logic is wrong? or maybe I’m misunderstanding something?
I think I see the issue you’re saying, but I don’t think this is issue with my code? Please check file attached.
I’ve commented out the while loop and added a print after the possible boolean
bool possible = Possible(crv, pln, dist);
Print(possible.ToString());
on load and recompute, it prints out
True
False
which is incorrect, but if I slide the slider the output becomes
False
True
which is correct, and even after changing slider value to the original 3.4, I still get the correct output
Only upon opening and recompute are the values wrong

EDIT:
I’ve narrowed it down to cSys.ZAxis on line165
on load and recompute, the ZAxis does not output any value (0,0,0 instead of 0,0,1)
it seems like on load and recompute this.Component.Params.Input[2].VolatileDataCount will detect a input even tho there’s nothing inputted, this prevents me from assigning the correct default value of new Vector3d(0, 0, 1)
So I guess the main question now is:
How do I define default values to an input if there’s no input (the way I’ve been doing it has weird quirks)
BTW: Sampling the Ccx events class in a List is pointless … since you’ll need some other Method to “extract” data (points, params etc etc). So do the right thing and get all these in a DataTree (of type object). For so few items the cost of unboxing is nothing.
