Reach Distance Visualizer

[hushed valve]

A mod that basically makes the raycast line for the reach hit calculation visible, to show exactly how long the reach distance is
Bonus: Logs in chat how far away you were hit from when hit, IF its over 3 blocks (with possibly a customizable minimum trigger distance)

That sounds like a good mod idea.

I'm no developer, so sorry. If I knew java, I would of helped.

What is the usage of this mod? Do you want to check if other players could have made a hit?

If you want to check your own player you can probably don't see the "line" because its not really visible in first person and thirdperson

https://github.com/DarkAndBlue/ReachDisplayMod is a bit older but could probably be ported to a new version (it shows the reach you had with your last hit as text on screen)

moreso just to show reach distance of other players, and while not really reliable due to ping, combined with ping logging and a bit else its not the hardest to calculate a client maximum possible reach

[near hornet]

It's really not possible to do that. I'm working inside an anticheat team and I know that the entity positions which the server sends are getting changed a lot by the server. So stuff like rotation, position and motion of the enemy players are not really usable for this.

For example Minecraft uses techniques to interpolate the entity motions to send less packets and save some traffic.

Better question, wouldn't it be possible to uninterpolate them serverside? Which while sacrificing bandwidth results in more accurate information

[hushed valve]

that or just recording everything serverside, which we plan sometime for a sorta hypixel atlus style anticheat

You could do that but it would require a modded server (or plugin) + a modded client.

But even with it you have the problem of not knowing when the player attacked the entity (at which client tick and where the entity position was when he attacked) Anticheats use transaction packets and some tricks for that.

So basically just using an anticheat? (And anticheats can detect reach with decimal places which a human would never detect)
