I can define a java script function in a cloud code. I cannot use this on other requests, responses cloud code. i know there is a concept as module but it has no interface, i have to use fixed variable names for both input and output. there should be a system like "include common.module" and it accepts java script functions in this module.
You can use
to import module code into other event code.
Check out the section about modules in the docs: https://docs.gamesparks.net/developer-portal/cloud-code
Thanks Jason, i thought require means execute. it includes code like you said it works.
