The "If" Statement
The "If" statement is also known as a branch statement. It is a conditional operator to perform comparisons and to do one thing based on the expression returning something and to do something else if the expression returns something else.if (weather == "nice") Draw.text(0,0,"The weather is nice.");Here you're checking if the variable weather is nice.
if (weather == "sunny") Draw.text(0,0,"The weather is sunny.");
If the weather is nice, it will say the weather is nice.
If the weather is sunny, it will say the weather is sunny.
Because a variable cannot have two values, it will either return one or the other.
You can also use "else" instead of making a second comparision.
if (weather == "nice") Draw.text(0,0,"The weather is nice.");The "else" statement in use.
else
Draw.text(0,0,"The weather is sunny."); // Given that the only other possible value is "sunny".
For values that return true or false, you don't have to use "if (variable == true)" or "if (variable == false)". Instead, you can use:
if (variable) // TRUE: do whatever"if (variable)" checks if the value returns true.
if (!variable) // FALSE: do whatever
"if (!variable)" checks if the value returns false.
Note that you can also use "=" rather than "==", but "==" is preferable.
