How to create a library from projects

Hi @urlxd, imo this is not really a processing question, but rather a java one… Also don’t know what OS you are working on so assuming Windows by using processing java mode. Further not knowing if you want to create a contributed library or only some function you want provide for yourself. if first one, look here: if the latter you can build a simple library depending on your java knowledge yourself. Just a demonstration not a recommendation create a directory structured …

Cheers
