Post subject:  i am in highschool, needing help from professionals.please..
i have a project in my Computer Programming Class,and i have never taken the class before ever, and i was late when joining it, because i transferred schools, anyways...i have this project that i am struggling with, heres the problem..

i cant figure out how to move the moon and all upwards, and get the chimney correct, and make the roof on the right not have the lines through it, if someone can help me with it, it would be muchly appreciated, or if someone can tutor me online with MSN or something through here. and one more thing, if u can help me simplify some of my commands in my program, that would be helpful also.

thanks

Drawing commands are simple. There is no difficult syntax, no difficult uses.

Know the difference between this:
code:

drawfillbox (100, 100, 400, 400, black)
drawfillbox (150, 150, 350, 350, white)

and this
code:

drawfillbox (150, 150, 350, 350, white)
drawfillbox (100, 100, 400, 400, black)


Though I haven't looked over your code much, I'd guess that's the problem you are having with your line through the roof. May also be the problem with your chimney. You're code is very uncommented though, so it's more difficult to help.
As for simplfying stuff, you could try use variables to store the position of your puffs of cloud, and of your moon. That way, you could make things simpler and also make the objects move more smoothly.

i dont understand what you mean Cervantes, by storing variables...i am not a very bright student, another classmate assisted a few things with me in this project, but nothing i cudnt handle..umm another thing, the things u made , where abouts do i put them?

Post subject: 
Cervantes, those drawfillboxes u made for me, cud u put them into the code, because im not sure where to put them, thanks, that wud be helpful

Post subject: 
Well, if by "the things u made", you mean the bits of code I posted, I'm scared.
Take those bits of code and put them in a new Turing program. one bit at a time (that means 2 lines at a time). Notice the difference.
Perhaps we should ignore the bit about storing information as variables for now.

oh ok thank you

Post subject: 
thank you cervantes, that little push got me to fix the whole side of my house, now the chimney, and can u help me with the moon?

Post subject: 
I don't know what you are trying to do with your moon. but I made this, using your code, to show you how to move it up, if that's what you wanted Confused
code:

var Y := 350
process mn
    loop
        drawfilloval (x2, Y + 30, 50, 50, 30)
        drawfilloval (x2 - 20, Y + 10, 5, 5, 28)
        drawfilloval (x2 - 11, Y + 30, 5, 5, 26)
        drawfilloval (x2 - 30, Y + 29, 5, 4, 28)
        drawfilloval (x2 - 4, Y, 4, 5, 27)
        drawfilloval (x2 + 26, Y + 40, 5, 2, 29)
        delay (100)
        x2 -= 1
        Y += 1
        drawfilloval (x2 + 1, 380, 50, 50, black)
        exit when x2 = 148
    end loop
end mn
fork mn

note how the moon leave's a gross looking trail behind it. You'll need to fix that up.

thank you very much....how long have you been working with turing?
Author:  sevendust [ Sun Dec 12, 2004 9:39 pm ]
Post subject: 
heres the program once again, run it and can u try to figure out how to move the one version back over to that it covers the trail or the real grey moon please
Author:  sevendust [ Sun Dec 12, 2004 9:47 pm ]
Post subject: 
actually forget about the last attachment, now i cant figure out this one, it wont let the moon dissapear...help me please

Post subject: 
It's hard, because you are using processes. Ordinarily, you'd just cls then redraw everything. But clsing in one process while a delay is going in another process would not be good. Either somewhow find a way to get rid of that streak behind the moon, or put it all in one main loop and use a cls.

Post subject: 
what is cls, and how do i use it?
Author:  Neo [ Sun Dec 12, 2004 10:15 pm ]
Post subject: 
cls is used to clear the screen. If you want to clear the moon trail without using cls you have to draw a black circle alittle bigger than the moon, behind the moon.

code:

process mn
    loop
        drawfilloval (x2 + 1, Y + 30, 51, 51, black)
        drawfilloval (x2, Y + 30, 50, 50, 30)
        drawfilloval (x2 - 20, Y + 10, 5, 5, 28)
        drawfilloval (x2 - 11, Y + 30, 5, 5, 26)
        drawfilloval (x2 - 30, Y + 29, 5, 4, 28)
        drawfilloval (x2 - 4, Y, 4, 5, 27)
        drawfilloval (x2 + 26, Y + 40, 5, 2, 29)
        delay (100)
        x2 -= 1
        Y += 1
        exit when x2 = 148
    end loop
end mn

Mind you, doing that would cause the moon to erase the stars.
Author:  sevendust [ Sun Dec 12, 2004 10:22 pm ]
Post subject: 
is there a way i can make the stars return, in any random order, or placed by myself??

Store the coordinates in an array and redraw them.
Author:  Cervantes [ Sun Dec 12, 2004 10:27 pm ]
Post subject: 
An array will work, but it is not the easiest of ways to go.
Trying taking a pic of the star's location at the start of your program (Pic.New I think) then using Pic.Draw in your moon process, before you draw your moon.
Author:  sevendust [ Sun Dec 12, 2004 10:27 pm ]
Post subject: 
how does it redraw them...and the commands you sent me Mr. Cervantes...didnt work on my moon
Author:  Neo [ Sun Dec 12, 2004 10:33 pm ]
Post subject: 
After you draw the house you want to take a picture of the house with Pic.New. Then redraw it in the loop.

um neo ... just to warn you before asiansensation comes along ... giving the whole program like that... not too safe (for yourself)

i was just wondering...why wud it be unsafe for him to send the whole program...all he did was help the last few lines...

because firstly the teacher could see and secondly compsci is a site for help not for code given so u could plagarize.

ahhi c, thanks, ill remember that for future reference, if i am one to give help to others...as if lol
thanks

by the ways forks and processes are very bad to use because its hard to get out of them.

I kinda had my doubts from the first post, the posts by sevendust seems more "asking for code" than "asking for help"

But I could just be paranoid.

So I'll watch until there is a definite sign of plagiarizing, then I'll do the necessary things.

Relax, I added 2 lines to his program and did not "give away the whole program". They werent even difficlut code to use, Pic.New and Pic.Draw Confused

exactly no big deal ... i just warned you and the right authority has stated a clear solution ... end of story

sevendust: continue on with your problem ... by the way, the second set of lines is drawing right over the other ones, try removing that part, i dont have turing on this computer, but i think that might work.

u were wrong, i figured out what the problem was, i moved it upwards, out of a possible loop statement, and that fixed it
thanks anyways
