The Physics Boulder is a large, rounded boulder that sits on a rocky base. The boulder can be released, and can roll or fall through the environment, depending on where you place it. It is subject to physics and gravity, so it will collide with players, creatures, vehicles, structures, and terrain. You can determine the maximum amount of damage the falling or rolling boulder does when it hits something (although the actual damage depends on the speed of the boulder on impact).

Some devices have a limit on how many times that device can be placed on an island. This is independent of how much memory the device uses. You can only place a total of 25 Physics Boulders and Physics Trees on an island; both types of Physics objects count toward that limit.
Finding and Placing the Device

-
From Create mode, press the Tab key to open the CREATIVE inventory screen.
-
Click the DEVICES tab. You can scroll to select the device, use the Search box to look up the device by name, or the Categories in the panel on the left.
-
Click PLACE NOW to place immediately, or put the device in the QUICK BAR to place later.
-
Press Esc to return to your island in Create mode. Use your phone to position the device, then click to place it. Press Esc to detach the device from your phone.
-
Point at the device with your phone. If the CUSTOMIZE popup doesn't open immediately, move closer until it does, then press E to open the Customize panel.
If you're using multiple copies of a device on an island, it can be helpful to rename them. You can choose names that relate to each device's purpose, so it's easier to remember what each one does.
Device Options
This device has some basic functionality, like setting the health of the boulder and its base. Additionally, there are some advanced options, like determining the maximum amount of damage the rolling or falling boulder does to players, creatures, vehicles, and the environment.
You can configure this device with the following options.
Default values are bold.
Basic Options
| Option | Value | Description |
|---|---|---|
| Health | Indestructible, 180, Pick an amount | Determines how much damage a boulder on its base can take before it is destroyed. |
| Leave Base | Yes, No | Determines if the boulder's base remains after the boulder is destroyed. |
| Base Health | Indestructible, 180, Pick an amount | Determines how much damage the boulder's base can take before it is destroyed. |
| Rolling Boulder Health | Indestructible, 900, Pick an amount | Determines how much damage a rolling boulder can take before it is destroyed. |
All Options (Additional)
| Option | Value | Description |
|---|---|---|
| Damage to Players | None, 150, Pick an amount | Determines the maximum damage a rolling boulder can do to a player. Actual damage to a player depends on the velocity of the boulder when it hits. |
| Damage to Creatures | None, 450, Pick an amount | Determines the maximum damage a rolling boulder can do to a creature. Actual damage to a creature depends on the velocity of the boulder when it hits. |
| Damage To Vehicles | None, 450, Pick an amount | Determines the maximum damage a rolling boulder can do to a vehicle. Actual damage to a vehicle depends on the velocity of the boulder when it hits. |
| Damage to Environment | None, 3000, Pick an amount | Determines the maximum damage a rolling or falling boulder can do to the environment on each hit. Actual damage to environmental objects depends on the velocity of the boulder when it hits them. |
| Timed Respawn | None, 15m, Pick an amount of minutes | Determines how long it takes for the balanced boulder to respawn on the base. |
| Boulder Base Required For Respawn | Yes, No | Determines whether the boulder base is required to respawn a balanced boulder. |
| Spawn When Enabled | Yes, No | Determines whether a balanced boulder automatically spawns when the device is enabled. |
| Destroy When Disabled | Yes, No | Determines whether a rolling boulder is automatically destroyed when the device is disabled. |
Channels
When one device needs to "talk" to another device, it does so by transmitting a signal on a specific channel. The receiving device needs to be set up to receive the signal on the same channel.
A channel is identified by a number, and channel numbers are customized for a device under the option that uses the channel. Most devices will also pass the identity of the player who triggered the device with the signal.
This device has receivers that perform a variety of functions when receiving a signal over a channel. Also, this device can transmit signals when certain conditions are met.
Receivers
Receivers listen for a channel and perform an action when they hear any device (including themselves) send a signal on that channel. This device has no receivers.
| Option | Value | Description |
|---|---|---|
| Spawn When Receiving From | No Channel, Pick a channel or enter a channel number | When the device receives a signal on the selected channel, it spawns the balanced boulder. This destroys any previously spawned objects. |
| Enable When Receiving From | No Channel, Pick a channel or enter a channel number | The device is enabled when it receives a signal on the selected channel. |
| Disable When Receiving From | No Channel, Pick a channel or enter a channel number | The device is disabled when it receives a signal on the selected channel. |
| Destroy All When Receiving From | No Channel, Pick a channel or enter a channel number | When the device receives a signal on the selected channel, it destroys all spawned rolling boulders. This does not release or destroy the boulder currently on the base. |
| Release Physics Object When Receiving From | No Channel, Pick a channel or enter a channel number | When the device receives a signal on the selected channel, it releases the boulder that is balanced on the base (if there is one). |
| Destroy Rolling Boulder When Receiving From | No Channel, Pick a channel or enter a channel number | When the device receives a signal on the selected channel, it destroys the current rolling boulder. |
| Destroy Base When Receiving From | No Channel, Pick a channel or enter a channel number | When the device receives a signal on the selected channel, it destroys the boulder's base. |
Transmitters
Transmitters send a signal on the selected channel when triggered.
| Option | Value | Description |
|---|---|---|
| When Balance Boulder Spawned Transmit On | No Channel, Pick a channel or enter a channel number | When the balanced boulder is spawned on the base, the device transmits a signal on the selected channel. |
| When Boulder Is Destroyed Transmit On | No Channel, Pick a channel or enter a channel number | When the boulder is destroyed, the device transmits a signal on the selected channel. |
| When Base Is Destroyed Transmit On | No Channel, Pick a channel or enter a channel number | When the base for the boulder is destroyed, the device transmits a signal on the selected channel. |
| When Rolling Boulder Is Released Transmit On | No Channel, Pick a channel or enter a channel number | When the rolling boulder is released from the base, the device transmits a signal on the selected channel. |
