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. + +diff --git a/src/main/java/net/minecraft/world/entity/projectile/Projectile.java b/src/main/java/net/minecraft/world/entity/projectile/Projectile.java +index 30eb86b52f00cfa61af4f93aca50ffc3547c95e8..7863625d49baa13ea87f2ee295b16706071fb960 100644 +--- a/src/main/java/net/minecraft/world/entity/projectile/Projectile.java ++++ b/src/main/java/net/minecraft/world/entity/projectile/Projectile.java +@@ -183,7 +183,7 @@ public abstract class Projectile extends Entity implements TraceableEntity { + this.shoot((double) f5, (double) f6, (double) f7, speed, divergence); + Vec3 vec3d = shooter.getKnownMovement(); + +- this.setDeltaMovement(this.getDeltaMovement().add(vec3d.x, shooter.onGround() ? 0.0D : vec3d.y, vec3d.z)); ++ if (!shooter.level().paperConfig().misc.disableRelativeProjectileVelocity) this.setDeltaMovement(this.getDeltaMovement().add(vec3d.x, shooter.onGround() ? 0.0D : vec3d.y, vec3d.z)); // Paper - allow disabling relative velocity + } + + // CraftBukkit start - call projectile hit event |
