DLively@ great to see someone making video tutorials that Acknex does really miss! Keep it up! But I have to say, that I don't really like the way you are writing your code.. It looks oldschool c-script way, which isn't the best way to handle everything with lite-c.
Example of what I mean:
if(key_w){
// then move player forward
}
if(key_s){
// then move player backward
}
Please, don't teach to write code this way, do it like (key_w - key_s), so it will be more clear and elegant. If you want to, I'll be happy to lend a hand of help you there with coding part! So we could create something like those unity tutorials.
My best wishes and keep it up please!
