Where Do I Start To Learning Lua? Youtube/Websites Both?

I would recommend watching beginner scripting videos experimenting with what you learned and watching more videos to work your way up as you go. But i'm not you and it's your decision on how you want to learn..

You learn, by making projects. Never say "I will never be able to make a game like that" because all things are possible, example say you want to make a game like jailbreak this time its twice as better, you would study jailbreak and see what it has, once you know, you would study piece by piece. Now this is just my opinion, some people say you need to read lua from chapter one to chapter 2, I say no way. I found learning lua way better, when I was devoted to finding out how to make a particular script. In short terms don't read lua chapter from chapter, it will,then become a chore dont get me wrong you might like it, but find something you want to,make wether its a fps, tps, racing, cops and robbers, find out,and you will automatically find yourself learning lua. Moreover, its all about what type of learner you are,that means if you retain things by hearing, you are a ear learner, if you retain things by reading you are a reading learner, if you retain things by seeing, you are a visual learner, so the question is up to you which way do you want to learn lua?
