There is a menu point “Delete Unused Variables”. It is very helpful for cleaning up blueprints. Why there isn’t such a point for functions? They can be found as written here but if the blueprint has hundreds of functions pressing “Find in Blueprints” for each of them is a headache. @SupportiveEntity, can you pay attention for this? Is it impossible, or why such point for functions (and macros?) have still not been added?
I usually delete the function directly, if nobody uses it it is deleted and if someone uses it a warning appears.
Although it does not work with functions in interfaces
Hey there @Etyuhibosecyu! I don’t believe there is a similar method for functions and macros, since the functionality for the search is already there that’s an excellent feature request I can agree with!
