Robot Specific Blocks#

The VR Rover has access to the standard VR Drivetrain, Events, Control, Operators, Variables, My Blocks, and Comments blocks.

Drivetrain #

Go to object #

The Go to object block is used to turn and drive the VR Rover to face a specified object.

This is can be a non-waiting or waiting block depending on if the and don’t wait option is used.

  go to [minerals v] ▶

Choose which object the VR Rover will go to. This could be minerals, an enemy, or the base.

  go to [minerals v] ▶

If the VR Rover detects multiple minerals or multiple enemies, it will move to the closer option.

By default, the Go to object block will block any subsequent blocks from executing until it’s finished. By expanding the Go to object block to show and don’t wait, blocks will continue to execute while the VR Rover is moving.

  go to [minerals v] ◀ and don't wait

In this example, the VR Rover will turn and drive to the closest mineral.

  when started
  go to [minerals v] ▶

Action #

Minerals action #

The Minerals action block is used to interact with minerals in the Rover Rescue Playground.

This is a non-waiting block and allows any subsequent blocks to execute without delay.

  minerals [pick up v]

Choose what the VR Rover should do with the minerals.

Picking up the minerals will place the minerals in the VR Rover’s storage. It will be carried around until the Minerals action block with either the ‘use’ or ‘drop’ is used in the project.

Using the minerals will replenish some of the VR Rover’s energy, as indicated by the battery icon in the Playground window. Minerals can only be used if they are on the ground.

The VR Rover will earn Experience Points (XP) by using minerals or dropping the minerals at the base.

In this example, the VR Rover will turn and drive to the closest mineral before picking it up.

  when started
  go to [minerals v] ▶
  minerals [pick up v]

Absorb enemy radiation #

The Absorb enemy radiation block is used to interact with enemies in the Rover Rescue Playground.

This is a non-waiting block and allows any subsequent blocks to execute without delay.

  absorb radiation

In this example, the VR Rover will turn and drive to the closest enemy before absorbing the enemy’s radiation once.

  when started
  go to [enemy v] ▶
  absorb radiation

Standby #

The Standby block is used to put the VR Rover into standby mode until the specified battery threshold is reached.

This is a waiting block and will not allow any subsequent blocks to execute until it has finished.

  standby until [50] % battery

When in standby, the VR Rover will use its battery slower, but the Number of Days Survived counter will increase at a higher rate.

Once the battery level threshold is reached, the VR Rover will come out of standby, going back to consuming its battery and increasing the Number of Days Survived counter at the normal rate.

Choose the battery threshold value at which the VR Rover will exit standby mode.

  standby until [50] % battery

In this example, the VR Rover will enter standby mode and wait until its battery has reached 35% before turning and moving to the closest mineral.

  when started
  standby until [35] % battery
  go to [minerals v] ▶
