vertex generation in Geant4 about bxdecay0 HOT 7 CLOSED

Hi Lowerce,
I'm preparing a specific example program with an implementation of a vertex generator based on a Box volume of the G4 geometry... Stay tune !

There is now a new example named bxdecay0_g4_ex02 (develop branch).
Please let me know if it helps you as is.

Example https://github.com/BxCppDev/bxdecay0/tree/develop/extensions/bxdecay0_g4/examples/bxdecay0_g4_ex02 has been updated and now includes a vertex generator class which loads vertex coordinates from a file. See the main program bxdecay0_g4_ex02.cc to activate or not this feature.

Thanks a lot for your example!
I learned a lot about vertex generator from your ex02.

P.S.
It seems that AddDaughter in DetectorConstruction.cc is not needed which causes double Source and SourceHole in World which are shown in Scene tree of Geant4 UI. And maybe some visual settings in vis.mac or Co60.mac should be changed to display the trajectory correctly (I can not use default visual settings to show that in my G4 environment).

Best regards，

I understand that AddDaughter is redundant to declare a daughter physical volume and probably bad practise in new version of G4... so I'll remove it. Thanks for the hint.

Thanks again for your detailed example about vertex generator ! So I will close this issue now.
And sorry for my ignorance of the feature in early version of Geant4.

You're welcome.
In fact, it was my ignorance of new practises in G4.10.X .
Basically, the management of some dynamically objects in G4 craps ("x = new XXX" but no "delete x", and no usage of smart pointers or references which would make things safer). That is not really orthodox programming in terms of memory management sanity and standard OOP practises but we have to live with that!
