Good to know: if / else

Want to make decisions in your code? Want to make your code respond to different situations? You might need if statements.

Try this code:

if(mouseX < 200) 
{
	background(0) // if true
} 
else
{
	background(100) // if false
}

What happens? Why?

An if statement reacts to true or false.

• If the condition is true, then the code in our if block will run.
• If the condition is false, then the code in our else block will run instead (if we even have an else block… because that’s optional!)
