TITLE
Programs can make decisions based on certain conditions. This allows programs to check if something is true or false and then run the appropriate code. These are called “If statements” which are also known as “conditionals.”
“If This/Then That” statements are also called “conditional statements.” These statements tell the computer what to do depending on if a condition is true or false. In order to jump in a video game, the program will check if the button is pressed. If that is true, the character jumps. If that is false, it does nothing. Since a player can jump at any time, the game must check the button many times every second.
