Hello, I've a problem, When I start the .bat file, then comes this when cygwin says that the program is succesfully installed :
He stays on this part :down: ,, Can someone help me?
Thnxx, Bennoo
*Sorry if this English is a little bit strange :p because i'm dutchman.*
The biggest difference is that you are calling a sin and cos math function 360 times each which is VERY expensive without a LUT. The other snippet didn't use any.Zitat:

i remember when i was seting up toolchain i had to go find mirors for half the files because they wern't there maybe you will to or you can try my toolchain.sh file http://rapidshare.com/files/12649221/toolchain.sh.htmlZitat:

yaustar - But it still drew a filled circle right? Just not as efficiently as another method... Im asking because I want to knwo if my mental calculations were wrong when i was writing that up. I cant check it as Im PSPless- but i suppose I could port it to lua and check it out...
Nope, I can't see it drawing a circle either.Zitat:

Would you mind posting the errors?Zitat:
Zitat von JaSo PsP
I sorted my problem out.

This does NOT draw a circle. It draws a bunch of lines from the "center" (x+radius, y+radius) to a number of points that lie between (-radius, -radius) and (radius, radius).Zitat:
Zitat von SG57
Even if you changed it to draw the lines from center to (center-radius | center+radius) then it would in most cases not be a completely filled circle. Apart from the thousands of times of overdrawing pixels unnecessarily, wasting even more cpu time than for the hundreds of trigonometric function calls.
If you want to draw filled primitves, always try to draw them in horizontal lines.

did u include the correct libs (including zlib)
You need to add
To your makefile's LIBS line. There is no reference there to a function in zlib PSPJunkie_.Code:-lpspgl -lpng
You may also have to add -lpspgum, but Im not seeing any references to it, so itd be unnecesary.
Your LIBS line in the makefile should look like this:
You also need to have libpng and zlib installed if you haven't already.Code:LIBS = -lpspgu -lpng -lz -lm

I'm guessing you mean to load splash.png instead.
lol , some questions
is it possible to let led's change of color , they are placed in the r and l button
i know this will be very difficult
any idea's?
What do you mean?Zitat:
Zitat von hallo007
You mean if you have LED's in the L and R button is it possible for them to change color with homebrew? If so, then I do think that is impossible. :S
i meant you needed to have it installedZitat:

Zitat von hallo007
if what PSPduh said is what you're trying to say, then no. because, the led operates straight from the battery, and has no relation to any other boards.
I'm trying to reinstall all the libs for my toolchain since I had to do a system restore, but the svn.ps2dev.org/psp/trunk/ isn't working and I can't download the libmad so far, any idea on what to do for this issue?
how do you copy a file from your memory stick to some other place on your memory stick
(for example copy_file(ms0:/reame.txt , ms0:/textfiles/);)
i tried the function to copy a file to flash , but it dindt work:(
just open one file for reading and one for writing then read a byte from the one you wish to copy. and write it to the write file, repeat until you have the entire file.Zitat:
Zitat von hallo007
also you could have searched, this has been asked many times before.
strcat(wattekopieren, gameEntry[current_selection].name);
i use this in a function for copy to ram
but when i later paste it reads the gameEntry[current_selection].name of now , but it needs to read the gameEntry[current_selection].name of the file i want to copy
Check out the file io example in PSPSDK, it has a handy write_file function which I use a lot :)Zitat:
Zitat von hallo007
yeah i know but i am working with a file browser
so i dont reads the file i want to copy , but where i want to paste:s
-= Double Post =-
for example
strcat(wattekopieren, gameEntry[current_selection].name);
at the moment i copy
ms0:/readme.txt
at the moment i want to paste my current selection is GAME
and then does it this
ms0:/readme.txt/GAME
Id atleast try to help, but I have 0 clue as to what you just tried to say...
Question -
If I do
Now the question I'm asking here is that does the else designate that s1, s2, and s3 all equal another value? Meaning:Code:if(s1 && s2 && s3 == 1) {
printf("LOL");
} else {
printf("ROFL");
I hope people understand...I want the else to designate that s1, s2, s3 are ALL equal to another value, ie all of them are 0 or 2, not s1 is 1, and s2 is 0, and s3 is 0.Code://does this:
if(s1 && s2 && s3 == 1) {
printf("lol");
}
if(s1 && s2 && s3 == 0) {
printf("rofl");
}
//equal this:
if(s1 && s2 && s3 == 1) {
printf("LOL");
} else {
printf("ROFL");
lol it's confusing to explain.
PSPduh - Once you enter an operator, anything after it is compared to it until another operator, logical AND (&&) being an operator, itll only take whats after it until the next operator. So waht your saying there...
Is if 's1' evaluates to true, and s2 evaluates to true, and s3 evaluates to 1 ('true' as well), then print LOL... else if any of those conditions arent met, perform the 'else' statement.Code:if(s1 && s2 && s3 == 1) {
printf("LOL");
} else {
printf("ROFL");
}
You could use an array and for loop to compare each element in that array to the same value in ~1 line of code... But that may not be what you want/are asking for...
And as for setting values to variables, you CAN do:
Some will say itd set s1 to s2, s2 to s3 and s3 to 1, but in all honesty, it sets s3 to 1, then s2 to s3 (1) and s1 to s2 (1), or atleast that is what appears to be going on, maybe theres some routine its using to set the variables to 1 thats different then this...Code:s1 = s2 = s3 = 1;
Also PSPduh - practice makes perfect, you could have found out the answers to your questions just by doing a simple app trying them out.
Yeh I was thinking that I shouldn't post the question but hell I posted it anyway.Zitat:
Zitat von SG57
But you did answer my question.
Oh well more typing for me.
If you want to check that all variables have the same value 0 or 1, you could do that by doing bitwise AND/OR and check if the result is the value they should have.Zitat:
Zitat von PSPduh
ie - if ((s1 & s2 & s3) == 1) ... or if you want to check for 0: if ((s1 | s2 | s3) == 0)
That is because if only one value of them were different, the changed bit would mask the others and therefore the end result would change too.
ie (1 & 0 & 1) = 0, (0 | 0 | 1) = 1 etc.
The check for 1 also works for any number of nonzero-bit lines, eg. if you check for 11b, 111b, 1111b, 11111b etc. as long as you are sure that none of the values will be bigger than that value.
For other cases you need to do it like this:
if ((s1==value) && (s2==value) && (s3==value))
Huh... I never really found a usage for the bitwise operators (besides the shifts, I believe those are bitwise?)... So, no matter what, when using a bitwise and/or, the values before the operator and/or are being compared to either 1, and, or 0, or.... I think Im reading that right... if not - know of any way that you found useful to understand it?
You use them mainly for masking out bits, so it's rarely used, since normally you don't pack values together into bigger datatypes (like 8 bools into one char). You will use that a lot when you do compression algorithms.
Could you explain that sentence in other words? I really dunno what you're trying to say.Zitat:
So, no matter what, when using a bitwise and/or, the values before the operator and/or are being compared to either 1, and, or 0, or
Also, bitwise ops are also useful in if statements with lots of checks, because in some cases it might be faster to do bitwise &| to find results than doing logic &&||.
That's because with logic &&||, every single expression is checked on itself and needs a branch instruction - those are slow. Bitwise ops only cost 1 clock cycle each and in the end, you only have one compare and branch instruction.
So say you have s1 = true, s2 = false, s3 = true and want to check if all of them are true:
if (s1 & s2 & s3) ... will resolve to two bitwise ops (2cylces) plus one branch on false.
if (s1 && s2 && s3) ... on the other hand, will resolve to three branch instructions in the worst case (all three are true), and two in this case.
If you want to check them to be all false, you'd need to OR them together.
Not the best example, but it should show what I'm aiming at.

you could also doZitat:
Zitat von Raphael
if( s1 == s2 == s3 == value ), that works on my compiler atleast.That makes the code shorter which I think is what duh wants..?
True :)Zitat:
Zitat von Waterbottle
Ok I think I used a bad example.Zitat:
Zitat von Raphael
I am NOT using 0 as false and 1 as true.
s1, s2, and s3 are integers, not bools.
I'm just using 0 and 1 because those were the first two numbers that came to mind.
I'm guessing that it would still work?
As said, for other values other then binary 1-strings you need to use the last method or the shortcut form:
if (s1 == s2 == s3 == value)
