Creating a 10x10 Multiplication Table in Flash AS3

Learn how to dynamically generate and display a 10x10 multiplication table using ActionScript 3.0 in Adobe Flash.

Generating dynamic content is a fundamental skill in ActionScript 3.0. This article will guide you through the process of creating a 10x10 multiplication table, displaying it on the Flash stage. We'll cover basic display object manipulation, loops, and string concatenation to achieve a clear and functional output. This example is perfect for understanding how to programmatically create UI elements and manage their layout.

Understanding the Core Logic

A multiplication table is essentially a grid where each cell contains the product of its row and column indices. For a 10x10 table, we'll need two nested loops: one for the rows (multiplicands) and one for the columns (multipliers). Inside these loops, we'll calculate the product and then display it. The challenge lies in arranging these results neatly on the Flash stage.

    A[Start Application] --> B{Initialize Display Objects}
    B --> C{Outer Loop: Multiplicand (1 to 10)}
    C --> D{Inner Loop: Multiplier (1 to 10)}
    D --> E[Calculate Product: Multiplicand * Multiplier]
    E --> F[Create TextField for Product]
    F --> G[Position TextField on Stage]
    G --> H{Inner Loop End?}
    H -- No --> D
    H -- Yes --> I{Outer Loop End?}
    I -- No --> C
    I -- Yes --> J[End Application]

Setting Up the Flash Project

Before writing the ActionScript code, ensure you have a new Flash (AS3) project. You can either create a new .fla file and attach the ActionScript to the main timeline, or create a separate .as class file and set it as the document class. For simplicity, we'll assume the code is placed directly on the main timeline's ActionScript layer.

import flash.text.TextField;
import flash.text.TextFormat;
import flash.display.Sprite;

var startX:int = 20;
var startY:int = 20;
var cellWidth:int = 40;
var cellHeight:int = 25;
var fontSize:int = 12;

var tfFormat:TextFormat = new TextFormat();
tfFormat.size = fontSize;
tfFormat.align = "center";

// Create a container for the table to keep it organized
var tableContainer:Sprite = new Sprite();
addChild(tableContainer);

for (var i:int = 1; i <= 10; i++) // Multiplicand (rows)
{
    for (var j:int = 1; j <= 10; j++) // Multiplier (columns)
    {
        var product:int = i * j;
        var tf:TextField = new TextField();
        tf.text = String(product);
        tf.width = cellWidth;
        tf.height = cellHeight;
        tf.x = startX + (j - 1) * cellWidth;
        tf.y = startY + (i - 1) * cellHeight;
        tf.border = true;
        tf.borderColor = 0xCCCCCC;
        tf.setTextFormat(tfFormat);
        tf.mouseEnabled = false; // Prevent interaction
        tableContainer.addChild(tf);
    }
}

Explanation of the Code

The code initializes several variables to control the layout and appearance of the table, such as startX, startY for positioning, cellWidth, cellHeight for cell dimensions, and fontSize for text size. A TextFormat object is created to ensure consistent text styling, particularly centering the numbers within each cell.

A Sprite named tableContainer is used to group all the TextField objects. This makes it easier to move or scale the entire table later if needed. The nested for loops iterate from 1 to 10 for both the multiplicand (i) and the multiplier (j). Inside the loops, the product is calculated, and a new TextField is created for each result. The TextField's x and y properties are calculated to position it correctly in the grid, and border and borderColor are set for visual separation. Finally, setTextFormat applies the defined styling, and mouseEnabled is set to false to prevent accidental interaction with the text fields.
