What is the purpose of the 'fill' block in Game Lab?

• To change the color used by Game Lab to a specified color, affecting all new shapes drawn until a new 'fill' block is used.

• To create a new shape in Game Lab.

• To erase shapes that have been drawn in Game Lab.

• To set the background color of the Game Lab environment.

What are velocity blocks in Game Lab?

• Velocity blocks are used to change the color of a sprite.

• Velocity blocks ('velocityX' and 'velocityY') control how fast a sprite moves in a direction.

• Velocity blocks determine the size of a sprite.

• Velocity blocks are used to play sounds in the game.

What are comparison operators?

• Operators that perform arithmetic calculations

• Operators that compare two values and return a Boolean value

• Operators that concatenate strings

• Operators that define variables

How do you draw sprites on the screen in Game Lab?

• Use the 'drawSprites()' block to draw all created sprites onto the screen.

• Use the 'renderSprites()' function to display sprites on the canvas.

• Call the 'displaySprites()' method to show sprites in the game.

• Invoke the 'paintSprites()' command to render sprites visually.

What is the assignment operator in programming?

• The operator used to compare two values.

• The operator that assigns a new value to a variable.

• The operator that performs arithmetic operations.

• The operator that defines a function.

How do you create a variable in programming?

• Use the 'var' command to create a new variable with a given label.

• Declare a variable using the 'define' keyword.

• Initialize a variable with the 'set' command.

• Create a variable by writing its name directly.

What is the purpose of functions in programming?

• To store data permanently in a database.

• To group commands under a name for reuse, improving organization, readability, and eliminating repetition.

• To create user interfaces for applications.

• To manage memory allocation and deallocation.

How are coordinates used in Game Lab?

• Coordinates in Game Lab use x and y values, where the x-coordinate indicates distance from the left side and the y-coordinate indicates distance from the top of the display area.

• Coordinates in Game Lab are only represented by x values, which indicate distance from the right side.

• Coordinates in Game Lab use only y values, which indicate distance from the bottom of the display area.

• Coordinates in Game Lab are not used for positioning elements on the screen.
