Core Mechanics: Building the Math Problem Generator

One of the key mechanics in Pippo Math is the ability to generate random math problems for players to solve. To make this happen, I created a Math Problem Generator in Unity using C# and TextMeshPro for UI text handling. Here’s a step-by-step look at how I built this core feature:

1. Setting Up the Equation Display

The first step was to create a space in the UI where the math problems would appear:

1. In Unity, I added a TextMeshPro Text to the scene, naming it EquationText.

2. This text dynamically updates with new math problems as the game progresses.

3. The text field was left empty in the editor because equations would be populated through code.

2. Creating the Math Problem Generator

Next, I built a script to handle the generation of random math equations.

1. Create the Script:

   • In the Project panel, I right-clicked > Create > C# Script and named it MathProblemGenerator.

2. Write the Code:
   Inside the script, I added logic to randomly generate addition and subtraction problems

Variable Setup:

equationText: Holds a reference to the UI text where the problem will appear

minNumber and maxNumber: control the difficulty by setting the range of numbers.

Generating Problems:

Randomly picks between addition and subtraction. 

num1 = Random.Range(minNumber, maxNumber + 1);

num2 = Random.Range(minNumber, num1 + 1);

Ensures subtraction problems always result in positive answers, making the game more suitable for kids.

Retrieving the Correct Answer:

Allows other scripts to easily access the right answer, making it simple to check player inputs.

4. Attaching the Script

1. Create GameController: I created an empty GameObject called GameController and attached the MathProblemGenerator script to it.

1. Link the Equation Text: In the Inspector, I dragged the EquationText GameObject into the script’s Equation Text field.

5. Testing the Generator

To test the script, I called GenerateNewProblem() each time a new round started. The equation updated instantly, with problems alternating between addition and subtraction, ensuring variety in every game session.
