TODO -> Update the “/gm” and “/takePDDLMove” descriptions

Basic player movements

  • Look - “/look yawAngle pitchAngle” -> Points the cursor in the pitch and yaw direction indicated

    • yawAngle -> the angle of rotation between -180 and 180 degrees
    • pitchAngle -> the up/down angle between -90 and 90 degrees

    • “/look xCoordinate yCoordinate zCoordinate” -> Points the cursor in the direction of the specified location - xCoordinate -> x-coordinate of location - yCoordinate -> y-coordinate of location - zCoordinate -> z-coordinate of location

    • “/look pitchAngle” -> Points the cursor in the pitch direction indicated while keeping the same yaw - pitchAngle -> the up/down angle between -90 and 90 degrees

    • “/looka direction” -> Points the cursor to the adjacent block in the indicated direction - direction -> one of the 8 compass directions: “n”, “ne”, “e”, “se”, “s”, “sw”, “w”, “nw” - Can also use “/lookadj” and “/lookadjacent”

      • Place Block

    • “/placeBlock” -> Places a cobblestone block at the foot level in the current direction - Turn

    • “/turn direction” -> Turns 90 degrees in the specified direction - direction -> “left” or “right”

      • Select Item in Inventory

    • “/selectItem itemIndex” -> Chooses the item at the given index (starts from 0) as the main item in the player’s hand - itemIndex -> Index of the item desired

Commands to Return Details

  • Take Screenshot - “/takePic” -> Takes a screenshot of the Minecraft game and saves it to the ?screenshots’ folder

  • Get Biome - “/biome” -> Returns the biome in which the player is currently located

  • Get Block - “/testPeek direction” -> Returns the block adjacent to the player in the indicated direction

    • direction -> one of the 8 compass directions: “n”, “ne”, “e”, “se”, “s”, “sw”, “w”, “nw”
    • Can also use “/peek direction”

  • Get blocks/entities in Minecraft frame - “/getInfoNoLook” -> Makes a list of the blocks/entities in the frame using raytracing - “/getInfoWithLook” -> Makes a list of the blocks/entities in the frame by looking at every pixel

  • Get object under cursor - “/getThingNoLook” -> Uses raytracing to return the object under the cursor - “/getThingWithLook” -> Uses the mouseOver object to return object under cursor

  • Simulate video and get objects/entities in video - “/getVidData numIterations” -> Captures frame data, moves 40 degrees, and repeats until full circle is made

    • numIterations -> If greater than 1, the player teleports 10 blocks forward in the x-direction, and repeats the rotations

Create Testing Scenarios/Obstacle Courses

  • Create Obstacle Course Sections - “/makeSection sectionName addGoal” -> Creates the specified obstacle course section with a gold block if desired

    • sectionName -> Letter of section to be created. See below for the types of sections and their associated letters.
    • addGoal -> If this is not null, a gold block is added to the end of the section

  • Create Obstacle Courses - “/makeObstacle numSections sectionName” -> Creates an obstacle course with the indicated number of sections, and if applicable, of only the given section - numSection -> Number of sections to use in the obstacle course - sectionName -> If not null, the course will consist of only this section

  • Create Test Scenarios - “/makeTest testCase” -> Creates the given test scenario

    • testCase -> Name of test case to create. See below for the types of cases and their names

Player Actions

  • Perform Subgoals - “/do subgoalName” -> Accomplishes the given subgoal towards the target if preconditions are met

    • subgoalName -> Name of subgoal. See below for details on the subgoals

  • Take Moves - “/takeExpertMove numIterations” -> Chooses a subgoal appropriate based on the environment and takes the action for the given number of iterations

    • numIterations -> Number of times the expert move should be taken. If “-1”, the player will keep taking the expert move until the target is reached
    • “/takeExpertMoveForHunt” -> Targets the nearest creeper and kills it
    • “/takeExpertMoveForMob” -> Targets any nearest mob entity and kills it
    • “/takeExpertMoveForWood” -> Finds wood and collects it
    • “/takeExpertMoveForBlock” -> Looks for block type that is directly under the cursor and mines it
    • “/takeOrderedMove numIterations” -> Similar to “/takeExpertMove”, the player goes through a preset order of subgoals and selects one that is appropriate - numIterations -> Number of times the ordered move should be taken. If “-1”, the player will keep taking the ordered move until the target is reached
    • “/takePDDLMove”

Miscellaneous

  • Set Targets - “/setTarget zDistance” -> Sets a target location a distance away in the z-direction

    • zDistance -> Amount of blocks away from the player in the z-direction
    • “/setTargetLoc xCoordinate yCoordinate zCoordinate” -> Sets a target location at the specified location - xCoordinate -> x-coordinate of location - yCoordinate -> y-coordinate of location - zCoordinate -> z-coordinate of location

  • Center Player to Block - “/snap” -> Snaps player to center of block it is currently on
