4.3: Using random() - Processing Tutorial

TL;DR

Learn how to use the random function in programming to introduce randomness and variety into code.

ok, let's wake up we just kind of get this idea we did something so small but so meaningful which was to introduce this idea of a variable now you might feel a little bit sad with just this grey circle moving on the screen and there's not really a lot happening and you want to have more splash, pizzaz in your program let's look at something that wi...

Key Insights

• 👨‍💻 Variables can be assigned values in programming to introduce variety into code.
• ↩️ The random function in programming is different from other functions, as it returns a random number in response to a question.
• 🧡 Random numbers generated by the random function can have decimal values, expanding the range of possibilities.
• 💻 The random function is a useful tool for creating behaviors and personalities in shapes drawn on the screen.
• 😫 Randomness can be controlled by setting minimum and maximum values for the random function.
• 💠 The random function can be used to create dynamic and unpredictable motion in shapes.
• 🧘 Randomness can be applied to various aspects of shapes, including size, color, and position.

Questions & Answers

Q: How does the random function differ from other functions in programming?

The random function is unique because it asks a question and returns an answer, rather than issuing a command or decree like other functions. It allows us to generate random numbers within a specified range.

Q: Can the random function generate floating point values?

Yes, the random function can return floating point values, which means it can produce an infinite number of possibilities within the specified range.

Q: Is the random number generated by the random function truly random?

The random number generated by the random function comes from a pseudo-random number generator, which is a mathematical function created by people. While it may exhibit some patterns over time, it is sufficiently random for most programming purposes.

Q: How can the random function be used to create dynamic behaviors in code?

By using the random function, values such as the location, size, color, and motion of shapes can be randomized, resulting in unpredictable and interesting behaviors in the program.

Summary & Key Takeaways

• Variables can be used to introduce more variety into code by assigning them values.

• The random function is a different kind of function that returns a random number within a specified range.

• Random numbers generated by the random function may have decimal values and can be used to create dynamic and unpredictable behaviors in code.
