Development Programming & Scripting Blueprint

After I modified code in the component .cpp and compile from the code editor then run the game I get errors from blue print that uses this component. After I open this blue print I found the component is missing and need to be added it again !!. Is there a way to prevent this behavior ?

because if I use this C++ component in many blue prints I have to search and readd them all again.

Try running the project from the compiler.

you mean live coding ?

No. I mean if you are using visual studio then run you projects .sln file and then run the project as development editor (with or without debug)

I’ve noticed in older versions if I didn’t compile from code my c++ classes would not be seen by blueprints.

Not sure if it’s been changed in newer versions, but it seems there that once compiled it seems to keep them in editor.
