Hello! I'm looking for a tutorial covering the absolute basics of Visual Logic for a complete newbie who's never used it before. There was a link posted in a previous post but it seems to be dead now. Thanks in advance.

Yeah, the video tutorials for visual logic are very limited, which is unfortunate, bc I feel lit is a very powerful tool and selling point for XPression. The help documentation is useful, but it is sadly limited as well. I just wish they would make a tutorial/help page briefly explaining all the function blocks in visual logic. Anyway, I'm going to suggest that this forum is the best place to figure out what you want to accomplish in visual logic. 

having said that, the function block that has helped me more than anything else in visual logic is the Input Selector. To my knowledge, it is NOT covered in the Xpression U video tutorials. A link that hopefully helps you see how it works can be found here . I studied software engineering and preferred using scripts in XPression, but I was persuaded by my peers to use Visual Logic, bc they did not understand code. Well, for me the most essential component in coding is an If Then Else statement. This can be accomplished in Visual Logic via the Input Selector, but is more like If 0 then, else if 1 then, else if 2 then, else if 3 then, etc. Therefore, it is quite often I have to use math operators like Greater Than, Less Than, Equal To, etc. or String Compare to convert my conditions to Boolean values, where a false condition returns a 0 and a true condition returns a 1. Next, plug that into the Input Selector "Index" node. (Now, if you have a condition that can have multiple results such as "if the text is DOG then...else if the text is CAT then...else if the text is SNAKE then..." you need to multiply the result of these comparison operators by values, such as 1, 2, 3, 4, etc. and add them up before plugging that into the Input Selector "Index.") Then you plug in what you want to happen into the Input Selector nodes [0], [1], [2], [3]...etc respectively for each of your results. The output of the Input Selector will feed the value of whatever you want to change. In the link I referenced Simon attached an example that is basically asking If Text1 is "BOB" make the color of Material3 #FFFFFFFF, else if Text1 is "BILL" make the color of Material3 #FFE71C1C, else if Text1 is "BARRY" make Material3 #FF5600FF. I this example he uses Max Value instead of Adding the Conditions before plugging that into the Input Selector Index. I always use Add, as I make sure each condition can only return a true or false result and there would never be 2 conditions that could be true at the same time. I hope this helps. good luck.

Go to help,  contents, search, visual logic, visual logic editor, scroll down, each block is described.

Wow! I never noticed that before. Thanks, Simon. I'm glad I took the time to help someone because this will help me a ton in the future.
