Enable creative mode and fly quickly.

The server will display warnings like this:

Additionally, the server-authoritative-movement setting in server.properties is not functioning as intended.

Even changing from server-auth to client-auth does not disable the rollback.

在 PlayerInvalidMoveEvent 之前有一个 if (invalidMotion) 判断

可以看下面这段从 Player.java 摘录的片段。

    protected void handleMovement(Vector3 clientPos) {
        if (!this.isAlive() || !this.spawned || this.teleportPosition != null || this.isSleeping()) {
            return;
        }

        boolean invalidMotion = false;
        Location revertPos = this.getLocation().clone();
        double distance = clientPos.distanceSquared(this);

        if (!this.level.isChunkGenerated(clientPos.getChunkX(), clientPos.getChunkZ())) {
            invalidMotion = true;
            this.nextChunkOrderRun = 0;
        } else if (distance > 128) {
            invalidMotion = true;
            getServer().getLogger().warning(String.format("%s moved too far (%.2f)", this.getName(), distance));
        }

        if (invalidMotion) {
            this.revertClientMotion(revertPos);
            return;
        }
