Jittery Entities
AlexanderwithaA opened this issue · comments
I have polymc and Yamato Gun on the latest version of minecraft, I used an override to do so. When I fire a gun the bullet jitters as it flies.

Also I tried disabling gravity with a command block yet it didn't allow me to do so, didn't like the entity id I put, so how is that formatted with polymc?
The main cause of this issue is PolyMc uses snowballs for this, which have slightly different physics to bullets. The situation can definitely be improved on PolyMc's side but any solution will have it's downsides.
Regarding the entity id, if you type @e[type=smth] then it might appear red on the client, but it'll still work if you press enter
I think replacing snowball with display entity with correct teleport interpolation for position and billboard enabled could solve this
That is the best option but I think you'd end up with slightly more lag since you'll miss out on the prediction part. Minor downside but still a downside. Calculating where the projectile will be next tick and sending that might help but I'm unsure if that's correct, will have to check projectile code.
