Sometimes, you might find yourself doing this:


It's not a big deal, but wasting a line of "if" just to filter out all conditions in which something might be true gets annoying. So, the game doesn't tell you this, but you can do this a shorter way


Notice the "!"? If you start the conditions of an if statement with !, it inverts the value. This is generally referred to as a "not" statement, and is one of the most fundamentally important functions of sequental logic. Unfortunately, I've yet to find a single time in the game that it tells you that you can do this. And yet still, it works!

On that subject are "and" and "or" statements.

Sadly, I've found considerable issues ingame trying to combine ! with && or ||.

Almost every function in the game that you will ever see is a "void" function, meaning it doesn't return a value. Most of the innate functions computers have that you regularly use, however, have return values. Void functions are great for a few things, but largely, their usage is limited and used for a single end.

However, you can make functions that return boolean values, strings, numbers, and even arrays. You make them much the same way as as void functions, but they have to end with a return value.

So, for example, let's say I want to make a function that takes a very large array like GetAllRooms(), and turn the resulting array into something more specific - Let's say I only want an array that contains rooms that have doors I can travel to.


This will return an array that only contains rooms with doors in them. Cool eh? All you have to do is call GetRoomsWithDoors(mf.GetAllRooms()).

Now, if you've ever tried to run a function like this, you might realize the actual depth of the problem- This function might not be very long, but the process to solve it is. In fact, this function searches EVERY ROOM IN THE GAME, looping through EVERY ITEM IN THE ROOM until it finds a door. Even if you've maxed your computer's ingame speed, this function will take more than a full minute to return all the rooms- something very annoying. There are less thorough, but MASSIVELY quicker ways to get this list, though.

This function is invaluable for filtering out garbage in enormous arrays. It's almost absent from almost every computer in the game- existing only in the weird Recorder computers that track if sebastian enters or hacks things in a room. A few of them have screens- most do not.

So, let's say we go to one of these computers and make a much faster function than the one before.


This will give you Rooms, an array containing all rooms in the game, EXCEPT those with "_locker" or "_inventory" in their names, giving you a list almost immediately.

But, how often are you going to be in one of the few rooms with one of these recorder computers? There is a solution for this:

Most people are familiar with how to do this


This just makes the computer named "Osc1" print "stuff" on its screen. You can make a computer do anything in its API list by using the dot operator like this. However, you can do much, much more with it.

You can use remote computers to give you all sorts of things.

You might have noticed before I called Connect("MainFrame") to give me the GetAllRooms() function. You can make ANY item with the connect API do this.


You can also call memories from any other computer the same way


This can be very useful for building programs that can do a wide variety of things that normally would require multiple different computers to achieve. But there's something else it can do too...

You can write your own string, number, bool, and array functions on another computer, and then call it from any computer in the game, without having to rewrite that function!

So imagine you make a tool like this on the computer Osc1


Then, on any computer


Using this trick, you can make very long, monotonous things that you type all the time into a single function that you can put on any computer who's name you remember (like the Osc1 - Osc4 ones), and use it without having to type it ever again. I can't tell you how often I use sorting functions like the one I mentioned earlier, and despise typing it out so often. This trick makes coding things far, far faster.

There are lots of other quirks of SPRAK that never get told to you ingame, and other tips and tricks that I'll include later. Till now, enjoy. I hope you learned something.
