You must compute for the total again in order to For example, we can get the price * quantity equation and store it in a variable like so:Īnd then in the trace statements, we can replace all the instances of the price * quantity equation with the total variable instead: You can also assign an equation to a variable. The FIRST set of trace statements will use the ORIGINAL values, because those trace statements were written BEFORE the values were changed. But after that, the variable values have been changed, so the second set of trace statements, which comes after the new values, will now use those new values instead. Here, when the first set of trace statements are executed, Flash will be taking a look at the original values. Trace("The new total is now: " + price * quantity) Trace("The new quantity is now: " + quantity) To check whether the new values have been successfully assigned, let's add another set of trace statements after the lines that assign the new values to the variables: So now, after the trace statements are executed, the variables will have these new values assigned to them. Let's try that.Īfter the trace statements, assign new values to the variables: You should see the output window display the following lines:Īfter assigning an initial value to a variable, you may still assign a new value afterward. In the third trace statement, price * quantity will be calculated, and based on our current values, it will result in a value of 15. For example, in the first trace statement, the variable name quantity will be displayed as 12, since 12 is the current value assigned to it. Here, the trace statements will evaluate the variables and equations, and will display their values.

Trace("The total is: " + price * quantity) Next, add some trace statements to verify that Flash is able to access the values assigned to the variables: This is pretty much the same thing, except we have fewer lines of code.

Here, each variable is declared and assigned a value in one statement.
#FLASH ACTIONSCRIPT 3.0 REFLECTION CODE#
Let's do that.ĭelete the lines of code that we've already typed and replace them with this: If you want, you can also combine the variable declaration and the value assignment in one statement.

You also don't need to declare the data type again. The var keyword is used to declare or create the variable. When assigning a value to a variable, there is no need to use the var keyword again since we've already done that at the beginning.
