This post was taken from my post on another forum account, on another website. I've altered it slightly to fit within MCSG, and explain a few things. Explanations are in italics and underlined.
I felt like perhaps this might benefit someone, and hopefully explain a bit further than what some other people may have been told, which is why I decided to post it here.
Ahh, heheheheh... *rubs hands together*
Ping. Latency. Internet connection. Similar terms.
Ping is measured in milliseconds - based off of that, your first assumption may be - 100 milliseconds? What difference is that when it comes to people PvPing?
Well, allow me to give you an example. (Numbers taken from [SNIP]'s /ping command -
A different server, not MCGamer. Unfortunately, MCGamer has a less accurate ping command at this time.)
I was PvPing an acquaintance earlier today, and he had roughly 68-87 ping. I checked our ping constantly, even in the middle of matches when I could get the opportunity.
While he had ping below 90, my ping was varying from ~160 to ~214. (I'm used to around 80-90 ping on other servers)
He was easily killing me with 5+ hearts left sometimes. I was slightly frustrated, I will admit. I then found out that my internet cord had been unplugged, and promptly went to resolve that. After a few seconds, my ping went to around 108, and more or less steady. After that, I quickly 3-0'ed him twice in a row. (
ranked 1v1's - The other server with the ping command is a 1v1 server, first one to 3 kills is victorious in the match.)
Now, I'm not one to blame ping most of the time, but when it gets to the point that my opponent is teleporting around slightly and I'm randomly getting killed after having 5 hearts just a second ago, it's sort of disadvantageous.
A ping difference of 50-100 can make the difference between being
able to land your hits, and not. A slightly smaller ping difference could be a deciding factor between who gets the first hit, and thus the first knockback - rendering the second person with higher ping literally
unable to land a hit, because they're knocked back before they can even say "Boo!" to the first fellow's armor. (In other words, they are knocked back before they come into range.)
Ping is the time that it takes for data to go between your computer and the server,
and back to your computer. In other words, take your ping and split it in half to find the time it takes for the server to receive a signal from your computer.
If you were to click 25 milliseconds before your opponent did, but your opponent had 50 less ping than you, they would still hit you first. The larger the difference, the more forgiving it is for them to make mistakes - they have a larger margin of error in which it can still work out for them. Considering some of us are able to click once or more every 1/10th of a second (100 milliseconds, I believe?) that can actually be quite a difference.
Back before (OP) ping really became a common term, we just called it "reach hacks".
BitoBain I heard you had some sort of dispute involving ping, I'm not sure what exactly it was, but hopefully this helps.
