Hello everyone!

Im pretty new to Processing but i've been given a task which i have to complete any day now. Ill write the part of it which confuses me the most, with hope that someone can explain me what exactly am i supposed to do and tip me with the methods to achieve it.

1) Develop a program that draws a square lattice of horiznotal and vertiocal light grey lines with a spacing of N pixels in a window of 700 by 500. ( so far everything is clear just wanted to introduce you to the task)

This is the part where i get confused:

- Then extend this program so that if the mouse button is pressed when the mouse button is close to a latice point then it gets from the keyboard a two-digit (e.g. 02,13,67) value. Interpret the two digit value, imput from the keyboard as the radius for circle to be drawn centered on the chosen lattice point. If any value imput is greater then the latice spacing devided by the square root of 2, then set it to be N/2 1/2 and that used as the circle radius. Allow a circle size at a lattice point to be changed. A way to do this is, when a point is selected to draw a circle in the background color of radius N/2 1/2 before drawind the new circle with the newly imput radius.

I'm looking forward for your help and i would like to thank you in advance

Someone see's it at least haha, I can't say the same for me, It's just it would be far more easier to understand the whole deal if you can see it written and trace the steps in order to understand it.

Thanks for the fast answer, I'll try 'cook' the ideas myself in the meantime, but if it's not much trouble to post it I would be gratefull.

Have a nice evening for now

samsara43, this is a blatant attempt (perhaps successful in this case) to get someone to do your homework / assignment.

If you are indeed grateful enough for the answer/solution, please tell us what course you are studying so that we can report you to your teacher.

Failing that, I strongly recommend that you either write for yourself significantly different code or simply go to your teacher and say that you don't know what to do.

There is no point in pretending you can do it if you can't, unless you are not actually interested in learning how to do it and are only doing the class to satisfy some other person's interest.

TfGuy44, I'm supposing you also noticed the question sounds familiar - see: keyboard input, trying to input a two digit number. In that case Mattje presented a couple of efforts in solving (part) of the problem, including a working solution and further went on to correct an error in the code you posted.

I'm guessing that Mattje and samsara43 are in the same class, and samsara is simply not trying. Mattje's first post about it was a week ago.

One might hope that any teacher of a Processing class checks these forums for students cheating, but we should also not feed people answers when it is obvious that is what they are doing.

Sorry - I'm going to back subpixel on this.  I see a lot of people asking for help without posting any code.  When they're offered a solution in code form they occasionally follow up with questions that indicate they have no understanding of the fundamental principles required to solve the problem and have made no effort to understand them - for example by working through the learning section.

If you want to ask a question that is clearly homework you need to demonstrate you've made some kind of effort.  In this case if, as you claim, you've understood the first part of the question then why not post the code that sets up the lattice  I'm afraid the impression you give is that you haven't even tried...

There are people on the forum all too happy to demonstrate they know how to implement a solution, but I'm not always convinced that's the best answer: IMO it's better to give guidance or code that demonstrates the principle rather than posting a direct solution to the problem...

That is unfortunate that you do not have a "teacher".

However, if the information from the course is not sufficient for you to understand the assignment, it is appropriate for you to contact whoever conducts the course to say so. If there was a level of assumed knowledge that you don't have, perhaps it is not the right course for you, and perhaps you can seek a refund.

I would advise if you are already in this far over your head that you are in trouble, and should really speak to the course administrator about it.

I am sorry if I upset you; I do believe that someone feeding you answers when you don't understand the basics is a recipe for continued problems, and will not ultimately be a good result for you.

As for spreading justice, it is every person's task to do so; if you do not uphold justice yourself, how can you expect to be treated justly? I would rather hope people complain about the spread of injustice.

I am a programmer, and it is in my interest to be interested in would-be programmers learning bad habits, or just not learning at all. The saying about a little bit of knowledge being dangerous is true for any complex endeavour, including programming.

I sympathise with you having a deadline and so on, but "the part where [you] get confused" is basically the entire problem, with several sub-problems, and you didn't give any clue as to what (in particular) you are confused about, which would lead any "help" to be "provide a complete solution" (and perhaps also explanation of the solution).

If you are having problems and have limited time, I suggest you start reading through the tutorials as soon as possible. Foundation learning is essential to your progress. Advancing beyond what you understand is really asking for stress and ultimately failure and disappointment.

PS: If you don't think I am inclined to help people, search for other posts I have made on these forums. I honestly don't think someone giving you the answer is helping; directing you to more basic instruction appropriate to your skill level is the best help you can get without in-person instruction.
