Coffee Machine scenario SECTION 3 Advanced Tutorial When the coin is inserted, we want to make a sound and change the displayed command. CALL Reset( ) 1, 2, 3… 1. Copy the sound file cashreg.wav from the folder of the sample programs to the project folder C:\Coffee . 2. Create a Page Script with Trigger Event of On Condition with an Expression of credit == 1 and script code of : displaytext = "Make a Selection" PlaySound("c:\coffee\cashreg.wav") Include a script for displaying the user selection in the Selection Display and assign this selection to the selection variable.
Use the variables selection to store the number typed, pressed to note when the first digit has been entered and selection_made to determine when the second digit has been entered therefore the selection is complete. 1, 2, 3… 1. Add an Execute Script animation to the Push Button with caption "1" with the following code: IF pressed == TRUE THEN selection = (selection * 10 ) + 1 pressed = FALSE ELSE selection_made = TRUE selection = 1 pressed = TRUE ENDIF selection_made = FALSE 2. Repeat for the other buttons, replacing both the 1's with the appropriate digit. To round off this step, include a script to produce the selection entered by the user. This script should:
• Display a message for informing the user what is happening. • Display the cup and the coffee liquid. • Play a sound file to simulate the coffee dropping, and one when finished. • Display a message to notify the user to pick up the coffee. 1, 2, 3… 1. Copy the sound files glu.wav and finished.wav from the folder of the sample programs to the project folder C:\Coffee . 2. Add a page script to trigger On Condition called Make the Drink with an expression of "(selection_made == TRUE) and (credit == 1) and (ready == TRUE)". Add the following code:
ready = FALSE displaytext = "Making your selection" cup.visible( 1) coffee.visible (1) for time_counter = 0 to 50 'just looping for coffee animation next PlaySound("c:\coffee\glu.wav") 27
