Logic "Lessons"

Archive: 12 posts


Yes, it has come down to this. I need lessons. if any of you sackthings would be kind enough it would be much appreciated.

I know a bit and how everything works, i am just so dense that i can't apply it. ANYTHING would be much appreciated. Logic is just not my thing, even though i can apply the smallest little bits.

Thanks to all.

I used to be really bad at logic. I would suggest watching all of comphermc's amazing tutorials. I love them as he explains how a piece of logic works. Then once you've watched them look at pieces of logic and see if you can explain how they work. Then watch a few more tutorials and you will understand them a lot better.

I've actually watched all of comphermc's tutorials twice. After watching them a second time after learning more about logic I understood a lot more about logic. If you want add me and I'll try to help you with logic.

Sure! I actually have watched them all, however some of the more advanced stuff he doesn't have. Its all pretty basic stuff there. I did my own lockbox without looking at his tutorial again, so i'm not completely stupid when it comes to logic. I'd have to personally show you what i want to happen; i think it is pretty complicated, for me anyway. I'll add you if that's fine with you.2012-01-27 16:26:00

If you haven't already, you might take a look through the wiki: http://wiki.lbpcentral.com/LBPWiki_Main
Personally, I prefer written information because I like to skim and then re-read particulars later.
The Creator's Tool Kit might also be useful, to learn by example: http://lbp.me/v/8s5ec2

I don't understand. What is it you want to learn? You paint compher's tutorials as "basic" (have you tried feedback loops?) yet you need lessons to apply your stuff? So you made a lockbox without help while logic 'is not your thing'; how is that not applied logic? How can we be sure you are not trying to set people up for sessions of "i know better!" and "impress me!"? Because that's the vibe I get from this thread.

Edit: on the other hand, if you are legit, then I apologize and offer this advice: follow the Help forums to get a feel for what people are struggling with. These are great cases of practice that put ones problem solving skill to the test, not to mention ones ability to articulate solutions in ways understandable to players of various logic degrees. This is the skill that compher's mastered in his videos and that is what makes them the best in this community; not how advanced his topics are (and some are).

Help others, become smarter. Win win for everyone.

@pookachoo
thanks for that lbp.me link! i'll check that out.

@Antikris
Of course i'm legitimate about this, why wouldn't i be? Of course i want to improve my skills. I need a better understanding of several things and how to get from point A to point B.

What i usually do: i see a friend's level with something that moves or i find interesting i immediately ask them how it works and the let me take a look at the chip(s).
when i referred to applying it, i mean that i have the knowledge of how stuff works, i just have a tough time seeing it all down. I often can't even start without giving myself some sort of brain pain. And sequencers-the one thing i forget every time. Just starting without seeing a chip from someone else is what catches me. I have nowhere to start.

EDIT:
Something that may help me:
Would someone mind sharing how they tackle on a logic problem/start a chip? I have found my point of struggle.

I don't really understand your question but to tackle a logic problem you often need to break it down into its smallest steps.

In a chip if there 3 inputs (A, B, C) and 1 output (F), and the output F only goes high when inputs A and B but not C is high then how will you implement that using logic gates? i.e. F=A?B?!C

Or if you try to imagine more practical problems in LBP like how to limit the signal from the analogue sticks to 20% strength when the player is in quicksand or something do you immediately apprehend how you would approach that problem?

If you're looking for problems to solve people post them in this subforum every day.

But you could think of any gameplay element, an inventory, a double-jump, the ability to change or upgrade weapons. These are all logic problems you could solve.

Go read rtm's logic blog (http://www.lbpcentral.com/forums/blog.php?4150-Logic-Blog) , that's where I started (can ignore most of the LBP1 stuff, though the emitter posts are still useful). Went from nowhere to, well, decent, in 2 weeks. It's a nice read if you're into that sort of thing.

It seems like you're looking for some sort of master logic creator to help you. Sorry, those don't really exist. Everyone makes their advanced logic differently, so it's near impossible to teach someone how to do it when their method might differ even slightly. It's just a matter of finding all the little quirks with logic and making things work.

What I've found is that you don't really 'learn' to make advanced logic, you just get more efficient at making it. That's probably the most important thing to remember, efficiency. Everything I make today I likely could have made a year ago, but now it takes me 1/10th the time to do so.

Try to replace something you made with another design that uses fewer parts if you're bored. It's good practice.

Also, read through the tuts and help section threads. Often people will post things that achieve something more efficiently. Anything of that sort will eventually help you become a better creator. What something achieves might not be new, but the process to get there usually is. After a while these things build up, allowing you to quickly determine the best designs to achieve what you want.

Thanks for all of this hlp guys. I'll check out the blog, the Toolkit, and everything else today. I can't thank you enough 2012-01-28 14:37:00

Would someone mind sharing how they tackle on a logic problem/start a chip? I have found my point of struggle.

First of all, I ask to myself what the chip must do.

With a detailed answer of this question, I ask to myself: how must it do it? Then, using my knowledge about logic gadgets and some imagination, I begin to figure out a picture in my mind (I don't know how to express it better) about how the chip must be built.

With the chip done, I test it's funcionality. If the chip must process multiple states/results or multiple conditions, I test them all. If something doesn't work, I make it work in create mode while seeing the chip's circuitboard (lights indicate what's on and what's off in the chip). Looking to the chip while it is working helps a lot to detect logic failures. Then, I try to identify the failure, and, with the failure/s identified, I figure out the solution/logic patch to resolve the logic bug.

This is my way for creating logics. Hope it will help.

EDIT: End the Creators Toolkit level to get the entire creators toolkit: it's a "physical object" that stores a lot of logic tools in different categories. You place it in your moon in create mode, then a lot of "categories" will be emmitted (chips representing categories will be emmitted). Inside every category there are chips. Most of the chips are logic chips that make all type of things (switches, advanced sensors, analogic signal handlers, etc.). But there's also a category called "physical objects". In this category, every chip has got an object stored inside an emmitter. It might be that other categories contain also some physical objects.

Every tool has got instructions inside a chip with the ? symbol sticked on the chip (under EVERY tool you'll find the ? chips). If notes are hidden, display them with R1 like if you were displaying a chip's circuitboard.

A physical tool called "Signal Display" can help you a lot for beta-testing advanced analogic chips. There are also a lot of other useful tools that I still use from the toolkit. (most of them analogic handlers). I also back-engineered them, that helped me to learn somemore.
