Starting off, a good chunk of this code isn’t even yours. The majority of the code is taken from the FastCast: Redux example gun. This is very similar to your previous “contributions” to this section, where you take someone else’s open source code, modify it a bit (if at all) and then publish it under your name with no credits given. The reasoning for this I have no idea, some sort of clout or popularity? Funny virtual numbers going up? Who knows.
Regardless, this isn’t yours. After the backlash you received from the “anti-exploit” you claimed to have made, I wouldn’t have imagined you’d have done it again. But alas, here we are. As a side-note, there’s nothing wrong with modifying open source code and re-releasing it (given you have the rights to do so, based on the license), but you shouldn’t take credit for the work of others.
Furthermore, using stolen models from a game that you don’t have the rights to doesn’t paint you in a good light. They might be freely available, due to being stolen, but just because other people might use them doesn’t mean you’re suddenly able to use them without infringing copyright.
All this, and I haven’t even got into the actual gun system itself.
As other people have mentioned, when ANY sort of latency is factored in the UX becomes horrendous, and it’s virtually unusable. This is why the client needs to run the bullet logic and then have the server verify it, as otherwise players are hit with terrible latency when using the weapons. It doesn’t make it any more secure (because people can just teleport or modify their speed to get behind anyone they want to kill and shoot them, and it’s all fine on the server!) and only makes it worse.
The other “security measures” you have also cause more harm than good. Obfuscating RemoteEvent names is never good because it just increases network usage for no reason. Exploiters will always be able to grab a reference to it, so there’s no point in trying to hide them (especially when it’s just harmful to a normal player’s experience).
TLDR: Stop stealing other people’s code and claiming it as your own. Stop using other people’s intellectual property without permission. Don’t release stuff with “#1 In Security” claims when your security measures are useless and only negatively affect the user experience.
I’d like to emphasise that you should contribute to the Resources section. There’s a ton of great stuff in here that helps out a ton of people every day, but please don’t fill it with stolen assets which are full of bad practices, as it could just harm people down the line.
