Unit 3: Lesson 4: Shapes and Parameters Flashcard

Front

What is the purpose of using parameters in shapes when creating interactive animations and games in code.org?

Back

To define the size and position of the shapes

Front

Which of the following is a correct way to draw a circle with a radius of 50 pixels at the position (100, 150) in code.org?
Options: `circle(100, 150, 50)`, `drawCircle(100, 150, 50)`, `createCircle(50, 100, 150)`, `circle(50, 100, 150)`

Back

`drawCircle(100, 150, 50)`

Front

Explain how changing the parameters of a rectangle can affect its appearance in an animation. Provide an example.

Back

Adjusting the width and height parameters can make the rectangle larger or smaller.

Front

If you want to create a square that changes size based on user input, which parameters would you need to adjust in your code?

Back

The width and height parameters

Front

A student wants to create a game where a character moves across the screen. Which strategic approach should they use to ensure the character moves smoothly?

Back

Plan a sequence of movements using consistent parameters for speed and direction

Front

How can you use reasoning to determine the best parameters for a shape that needs to fit within a specific area of the screen?

Back

Measure the area and calculate the parameters based on the available space

Front

What is the result of setting the same value for both width and height parameters in a rectangle function?

Back

A square

Front

In an interactive game, how can parameters be used to create a challenge for the player? Options: By making the shapes invisible, By adjusting the speed and size of obstacles, By changing the background color, By adding more sound effects

Back

By adjusting the speed and size of obstacles

Front

A game developer wants to create a dynamic background that changes color based on the time of day. What strategic thinking process should they use to implement this feature? Options: Use a fixed color for all times of the day, Plan a color transition algorithm that adjusts parameters based on time input, Change colors randomly, Use a single color for the entire game

Back

Plan a color transition algorithm that adjusts parameters based on time input

Front

Which of the following statements is true about the use of parameters in creating interactive animations?
Options:
Parameters are only used for aesthetic purposes.
Parameters allow for customization and control over the animation's behavior.
Parameters are not necessary for creating animations.
Parameters are used to add sound to animations.

Back

Parameters allow for customization and control over the animation's behavior.
