Hi LinKin , my name is teQuilla.
I've made over $200 with scripting for MTA , and the experience is pretty fine . Had some difficulties sometimes , but we fixed it in the end.
I see you're concerned about the security of your scripts . Everybody is , as for the luac encryption , it doesn't helps at all , because there are alot of decompilers out there. Though you might want to use luac for small scripts ( Vehicle Spawner for example . ) , but for big gamemodes ( Like Race including all the fancy stuff , or vH scripts ) you might want to do your own security system . I know this sounds like a stupid idea for alot of you , but creating a security system that requires a License key , that once used it registers the IP of the server in a website , and everytime a script or something from the gamemode is run , it requires a check that the License is valid , and compares the website's IP to the server's IP . To prevent them for editing this edit system , you should use .luac encryption , and you need a pattern that only you know for the license key , then preferably use sha256 to encrypt it even further.
I know this might sound stupid and a lot of work to do for you , but for me it's working like charm .
Sorry for my english , it's 3 AM here and I'm pretty tired . If you didn't understand what I told you , just leave a comment and I'll explain tomorrow .
