Discoveries: Ultimate Quizizz Chapter 1 Part 2

Bug

• Part of a program that does not work correctly.
• the rate at which frames in an animation are shown, typically measured in frames per second
• An algorithm that has been coded into something that can be run by a machine.
• A graphic character on the screen with properties that describe its location, movement, and look.

An algorithm is

• a dance
• measures your heartbeat
• a list of steps to complete a task
• musical 

Predict what will show up on console.log

• true true true

• true false false

• false false false

• true false true

What happens if you don't call background in your draw loop and your sprite has movement?

• nothing, animation is fine.

• the sprites are drawn on top of each other to simulate movement, the older drawings don't get erased.

• you don't need to call background because you don't have one.

• you can just use sprite.move( ) so there's no need for the function background( )

In the draw loop, if you call the text function before the drawSprites and/or background function, what happens?

• You won't be able to see your text because the sprites and background will be drawn on top of the text.

• You will be able to see your text because Game Lab knows you want to see the text.

• You won't be able to see your sprites or background because order doesn't matter.

• You will be able to see your text because the sprites and the background will be drawn after the text.

the if(keyDown(up)) returns

• a boolean value of true if the user presses the down key

• a boolean value of false if the user presses the down key

• A boolean value of true if the user presses the up key

• A boolean value of false if the user presses the up key

Boolean Expression

• a single image within an animation
• A single value of either TRUE or FALSE
• A piece of code that you can easily call over and over again.
• Finding and fixing problems in your algorithm or program.

Conditionals

• Any valid unit of code that resolves to a value.
• a single image within an animation
• Statements that only run under certain conditions.
• Any valid unit of code that resolves to a value.

If-Statement

•  The common programming structure that implements "conditional statements".
•  Attributes that describe an object's characteristics
• An algorithm that has been coded into something that can be run by a machine.
• Part of a program that does not work correctly.

Boolean
