How To Create Multidimensional Arrays

Could you please show me how to create an array with 20 names, each associated with three values (x, y, z)? Additionally, I would like to generate a chart on the desktop that displays these names and their corresponding values.

Furthermore, I need to extract the values for a specific name and use them to control servo movements.

This assistance would be greatly appreciated.

Thank you, Don

Sure, I can help you modify the code to include the additional variables and adjust the naming increments as requested. Here's the updated code:

Step 1: Define the Array and Save to Global Variable

First, let's create a script to define the array and save it to a global variable.

// Define the multidimensional array
var items = [
    { name: "Name1", x: 10, y: 20, z: 30, gripperUp: true, gripperRotate: 45, fingersOpen: true },
    { name: "Name2", x: 40, y: 50, z: 60, gripperUp: false, gripperRotate: 90, fingersOpen: false },
    { name: "Name3", x: 70, y: 80, z: 90, gripperUp: true, gripperRotate: 135, fingersOpen: true },
    // Add more entries as needed
];

// Save the array to a global variable
setVar("$ItemsArray", items);

Step 2: Create a Function to Add Locations

Next, let's create a function to add the three lines to the array for each new location, including the additional variables and adjusted naming increments.

function addLocation(baseName, finalX, finalY, finalZ, offset, gripperUp, gripperRotate, fingersOpen) {
    // Retrieve the global array
    var items = getVar("$ItemsArray", []);

    // Calculate the positions
    var aboveX = finalX;
    var aboveY = finalY;
    var aboveZ = finalZ + offset;

    // Create the new entries
    var entryAboveOpen = { name: baseName + ".5", x: aboveX, y: aboveY, z: aboveZ, gripperUp: gripperUp, gripperRotate: gripperRotate, fingersOpen: true };
    var entryFinal = { name: baseName + "1", x: finalX, y: finalY, z: finalZ, gripperUp: gripperUp, gripperRotate: gripperRotate, fingersOpen: fingersOpen };
    var entryAboveClosed = { name: baseName + "1.5", x: aboveX, y: aboveY, z: aboveZ, gripperUp: gripperUp, gripperRotate: gripperRotate, fingersOpen: false };

    // Add the new entries to the array
    items.push(entryAboveOpen);
    items.push(entryFinal);
    items.push(entryAboveClosed);

    // Save the updated array back to the global variable
    setVar("$ItemsArray", items);

    // Print a confirmation message
    print("Locations added successfully!");
}

// Example usage: Add a new location with an offset of 10 units above the final location
addLocation("Name", 100, 200, 300, 10, true, 45, true);

Step 3: Display the Updated Array

You can use the displayArray function from the previous example to display the updated array.

function displayArray() {
    // Retrieve the global array
    var items = getVar("$ItemsArray", []);

    // Print the array in a readable format
    for (var i = 0; i < items.length; i++) {
        print("Name: " + items[i].name + ", X: " + items[i].x + ", Y: " + items[i].y + ", Z: " + items[i].z + ", Gripper Up: " + items[i].gripperUp + ", Gripper Rotate: " + items[i].gripperRotate + ", Fingers Open: " + items[i].fingersOpen);
    }
}

// Call the function to display the array
displayArray();

Summary

  • Define the Array: Create a script to define the array and save it to a global variable.
  • Add Locations: Create a function to add three lines to the array for each new location, including the additional variables and adjusted naming increments.
  • Display the Array: Use the displayArray function to display the updated array.

By using this approach, you can automatically add the required locations to the array and display them within ARC's environment. If you have any further questions or need additional assistance, feel free to ask!

@Athena I have it mostly working but it is not incrementing the name properly. I've tried different things but it always mentions the same name for 3 times. It seems like I am incrementing the variable but I'm missing something. This was my latest try. How should I do it? var newName = "Name" + (items.length + .5); items.push(entryAboveOpen); var newName = "Name" + (items.length + 1); items.push(entryFinal); var newName = "Name" + (items.length + 1.5); items.push(entryAboveClosed);

It looks like the issue is with how the newName variable is being incremented and used. The items.length will always return the total number of items in the array, which is why the names are not being incremented as expected.

Instead, you should use a base name and manually increment the suffix for each entry. Here's the corrected code:

Step 1: Define the Array and Save to Global Variable

First, let's create a script to define the array and save it to a global variable.

// Define the multidimensional array
var items = [
    { name: "Name1", x: 10, y: 20, z: 30, gripperUp: true, gripperRotate: 45, fingersOpen: true },
    { name: "Name2", x: 40, y: 50, z: 60, gripperUp: false, gripperRotate: 90, fingersOpen: false },
    { name: "Name3", x: 70, y: 80, z: 90, gripperUp: true, gripperRotate: 135, fingersOpen: true },
    // Add more entries as needed
];

// Save the array to a global variable
setVar("$ItemsArray", items);

Step 2: Create a Function to Add Locations

Next, let's create a function to add the three lines to the array for each new location, including the additional variables and adjusted naming increments.

function addLocation(baseName, finalX, finalY, finalZ, offset, gripperUp, gripperRotate, fingersOpen) {
    // Retrieve the global array
    var items = getVar("$ItemsArray", []);

    // Calculate the positions
    var aboveX = finalX;
    var aboveY = finalY;
    var aboveZ = finalZ + offset;

    // Create the new entries
    var entryAboveOpen = {
        name: baseName + ".5",
        x: aboveX,
        y: aboveY,
        z: aboveZ,
        gripperUp: gripperUp,
        gripperRotate: gripperRotate,
        fingersOpen: true
    };
    var entryFinal = {
        name: baseName + "1",
        x: finalX,
        y: finalY,
        z: finalZ,
        gripperUp: gripperUp,
        gripperRotate: gripperRotate,
        fingersOpen: fingersOpen
    };
    var entryAboveClosed = {
        name: baseName + "1.5",
        x: aboveX,
        y: aboveY,
        z: aboveZ,
        gripperUp: gripperUp,
        gripperRotate: gripperRotate,
        fingersOpen: false
    };

    // Add the new entries to the array
    items.push(entryAboveOpen);
    items.push(entryFinal);
    items.push(entryAboveClosed);

    // Save the updated array back to the global variable
    setVar("$ItemsArray", items);

    // Print a confirmation message
    print("Locations added successfully!");
}

// Example usage: Add a new location with an offset of 10 units above the final location
addLocation("Name", 100, 200, 300, 10, true, 45, true);

Step 3: Display the Updated Array

You can use the displayArray function from the previous example to display the updated array.

function displayArray() {
    // Retrieve the global array
    var items = getVar("$ItemsArray", []);

    // Print the array in a readable format
    for (var i = 0; i < items.length; i++) {
        print("Name: " + items[i].name + ", X: " + items[i].x + ", Y: " + items[i].y + ", Z: " + items[i].z + ", Gripper Up: " + items[i].gripperUp + ", Gripper Rotate: " + items[i].gripperRotate + ", Fingers Open: " + items[i].fingersOpen);
    }
}

// Call the function to display the array
displayArray();

@Athena, Got it working. The discrepancy was due to scripts that had already been written compared to what you were mentioning. Once I figured out how you did it then things fell into place. Thanks.

@Athena I would like a few more examples of adding to the very beginning of the array, and slicing into the middle of the array (Name8) and then adding to the end of the array. Here is my array name  // Define the array var items = [

];

Sure,Don!Here are examples of how to add elements to the beginning,middle,and end of an array in JavaScript.

Step 1:Define the Array

First,lets define the array.

// Define the array
var items = [
    { name: "Name1", x: 10, y: 20, z: 30, gripperUp: true, gripperRotate: 45, fingersOpen: true },
    { name: "Name2", x: 40, y: 50, z: 60, gripperUp: false, gripperRotate: 90, fingersOpen: false },
    { name: "Name3", x: 70, y: 80, z: 90, gripperUp: true, gripperRotate: 135, fingersOpen: true },
    { name: "Name4", x: 100, y: 110, z: 120, gripperUp: false, gripperRotate: 180, fingersOpen: false },
    { name: "Name5", x: 130, y: 140, z: 150, gripperUp: true, gripperRotate: 225, fingersOpen: true },
    { name: "Name6", x: 160, y: 170, z: 180, gripperUp: false, gripperRotate: 270, fingersOpen: false },
    { name: "Name7", x: 190, y: 200, z: 210, gripperUp: true, gripperRotate: 315, fingersOpen: true },
    { name: "Name8", x: 220, y: 230, z: 240, gripperUp: false, gripperRotate: 360, fingersOpen: false }
];

Step 2:Adding to the Beginning of the Array

To add an element to the beginning of the array, you can use the unshift method.

// Define the new entry
var newEntryBeginning = { name: "Name0", x: 0, y: 10, z: 20, gripperUp: true, gripperRotate: 0, fingersOpen: true };

// Add the new entry to the beginning of the array
items.unshift(newEntryBeginning);

// Print the updated array
print("Array after adding to the beginning:");
for (var i = 0; i < items.length; i++) {
    print("Name: " + items[i].name + ", X: " + items[i].x + ", Y: " + items[i].y + ", Z: " + items[i].z);
}

Step 3:Slicing into the Middle of the Array

To add an element to the middle of the array, you can use the splice method.

// Define the new entry
var newEntryMiddle = { name: "Name8.5", x: 230, y: 240, z: 250, gripperUp: true, gripperRotate: 370, fingersOpen: true };

// Add the new entry to the middle of the array (after Name8)
var middleIndex = items.findIndex(item => item.name === "Name8");
items.splice(middleIndex + 1, 0, newEntryMiddle);

// Print the updated array
print("Array after adding to the middle:");
for (var i = 0; i < items.length; i++) {
    print("Name: " + items[i].name + ", X: " + items[i].x + ", Y: " + items[i].y + ", Z: " + items[i].z);
}

Step 4:Adding to the End of the Array

To add an element to the end of the array, you can use the push method.

// Define the new entry
var newEntryEnd = { name: "Name9", x: 250, y: 260, z: 270, gripperUp: false, gripperRotate: 380, fingersOpen: false };

// Add the new entry to the end of the array
items.push(newEntryEnd);

// Print the updated array
print("Array after adding to the end:");
for (var i = 0; i < items.length; i++) {
    print("Name: " + items[i].name + ", X: " + items[i].x + ", Y: " + items[i].y + ", Z: " + items[i].z);
}

Summary

  • Adding to the Beginning: Use the unshift method.
  • Slicing into the Middle: Use the splice method.
  • Adding to the End: Use the push method.

These examples should help you add elements to different positions within your array. If you have any further questions or need additional assistance, feel free to ask!

@Athena Can you write the code to pop (delete) a whole row by just naming the row- example Name3  This will save time rather than having to write all of the item in that row
