Vehicle & Riding Physics
This page details how Speedometer accurately measures movement velocity while riding mounts, boats, minecarts, or flying with Elytra.
📊 Vehicle Physics Infobox
| Vehicle / State | Velocity Source | Typical Speed Range ($\text{b/s}$) | Peak Speed ($\text{b/s}$) |
|---|---|---|---|
| Vanilla Boat (Water) | Boat Entity | $8.00 - 9.00\text{ b/s}$ | $9.00\text{ b/s}$ |
| Boat on Blue Ice | Boat Entity | $40.00 - 70.00\text{ b/s}$ | $72.70\text{ b/s}$ |
| Minecart (Powered Rail) | Minecart Entity | $8.00\text{ b/s}$ | $8.00\text{ b/s}$ |
| Horse (Max Stats) | Horse Entity | $14.50 - 14.75\text{ b/s}$ | $14.75\text{ b/s}$ |
| Pig (Carrot on a Stick) | Pig Entity | $4.20 - 5.00\text{ b/s}$ | $6.80\text{ b/s}$ |
| Elytra Glide / Dive | Player Entity | $15.00 - 45.00\text{ b/s}$ | $67.50\text{ b/s}$ |
🏎 Camera Entity Velocity Resolution
When a player mounts an entity (e.g. a boat or horse), Minecraft shifts the client's camera entity or delegates movement authority. Speedometer retrieves velocity using:
java
Entity entity = client.getCameraEntity();
if (entity == null) {
entity = client.player;
}
Vec3 knownSpeed = entity.getKnownSpeed();- Riding Mounts:
client.getCameraEntity()automatically resolves to the ridden vehicle entity (or player camera attachment), extracting the exact server/client synced velocity vector of the mount. - Spectator Mode: When spectating another player or entity, Speedometer displays the target entity's real-time movement velocity rather than zero.
