Are you sure it speeds things up lol?

yes

I don't see it as a sure thing, but it might work for someone else.

^ is saying that using the old mmemoryproxy that gets shifted every frame wont benefit from using a faster algorithm that also calculates the hash less often

You are free to use it if you wish; however, I personally wouldn't, as I have a considerably better alternative. Generally, these types of resources are shared when they are no longer useful, although they can serve as a reference for someone with experience to improve upon them or develop a more efficient solution.

If you have a faster version, why not share it? Ragezone is all about sharing source.

I want to make it clear that I have no connection to you and no interest in associating with you. I don't know you, nor do I consider it necessary to get to know you, and I have no intention of becoming involved.

Regarding the concept of "community" that you mention, from my perspective, GunZ has never had a truly solid community. Trying to build one is valid, but it's not always successful, and in this case, I believe it hasn't been effective. In fact, certain attitudes within the community contribute to the game's lack of growth and positive evolution.

For that reason, I prefer to remain independent and not be part of what I consider a fictitious community with toxic tendencies, one that doesn't offer a clear or constructive direction.

With nothing further to add, I bid you farewell.

Consider this section a memorable demonstration; I don't usually repeat these kinds of interventions, especially when they yield such compelling results. Frankly, I no longer find this particularly entertaining.

what a great chatgpt essay!

Este es un sistema de protección que necesita actualizarse aún más porque, tal como está, puede causar errores; es simple, pero no es un acelerador.

I don't waste my time arguing with NPCs or random weirdos I've never even seen before. I honestly don't know where these people come from.

I think you just missed the point, friend . The problem isn’t making the hash faster, it’s avoiding recalculating the hash all the time. When I have time, I’ll show the solution and then contribute it to the community.
