Subject: [PATCH] Configurable projectile relative velocity
|
|
|
|
This patch adds an option "disable relative projectile velocity", which, when
|
|
nabled, will cause projectiles to ignore the shooter's current velocity,
|
|
like they did in Minecraft 1.8 and prior.
|
|
If a player is falling, for example, their shooting range will be drastically
|
|
reduced, as a downwards velocity is applied to the projectile. This prevents
|
|
players from saving themselves from falling off floating islands, for example,
|
|
as a thrown ender pearl will not make it back to the island, while it would
|
|
have in 1.8.
|
|
|
|
While this could easily be done with plugins, too, there are multiple problems:
|
|
P1) If multiple plugins cancel the velocity by subtracting the shooter's velocity
|
|
from the projectile's velocity, the projectile's velocity would be different.
|
|
As there's no way to detect whether the projectile's velocity has already been
|
|
adjusted to ignore the player's velocity, plugins can't not do it if it's not
|
|
necessary.
|
|
P2) I've noticed some inconsistencies, e.g. weird velocity when shooting while
|
|
using an elytra. Checking for those inconsistencies is possible, but not as
|
|
efficient as just not applying the velocity in the first place.
|
|
P3) Solutions for 1) and especially 2) might not be future-proof, while this
|
|
server-internal fix makes this change future-proof.
