Hello, whoever you are. I've never seen you here before. A couple things for you.
First, it is not redspot that is griggering your windows defender, it is the BGT engine. I'd like to know who started that rumor. Someone must have written some kind of virus in BGT and been stupid enough to use it on someone. The victim reported it to Microsoft, so now windows defender thinks many bgt executables are viruses. My windows defender goes wild when I run crazy party on a new machine and I have to add an exclusion for the entire drive that it's on to get it to stop.
Second, you're talking like game development is something anyone can pick up and do just like that. Every published developer on this forum learned a programming language (yes folks, bgt is a real, all be it not great, programming language). Just learning the language requires a gigantic effort. I'm in the process of learning python right now, and I can tell you, even simple scripts won't come easy to you at first. I've been at it basically non stop in my spare time for a couple weeks, and i'm just now getting to the point where I can write a basic battleship game. Mind you, not a battleship game that speaks and plays sounds in a pretty audiogame interface, no sir. A battleship game that you play in the command line by typing x, y to fire at a coordinate and receive a visual of the board in ascii showing you if you hit or missed. But even that took work, and if I asked most of you to write one for me right now you'd shrug helplessly and ask me what function to write first. I'd of course reply that you don't write a function first, you import other classes first, namely the random class so you can use it to generate random integers to place the ship. And that's just learning the language, and getting comfortable enough with it to know how to write it. It takes years of practice to learn all the intricacies of programming and write real revenue generating content. And you mentioned finding awesome weapon sounds and balancing the game, again like they're no big deal. Getting sounds, legally, costs money, and game balancing is a constant struggle for developers that huge game companies pay designers hundreds of stacks a year to get just right, and still not everyone's happy. I'm not saying any of this to show off my knowledge but merely to slam the point home that game development, just like anything worth doing, is not easy, and that's vastly understating it.
