This is making the font small and upscaling. Making the font bigger kept the squares[/QUOTE]

looks like a linear texture mag filter to me. If you're using OpenGL, make sure that the tex parameter GL_MAG_FILTER is set to GL_NEAREST instead of GL_LINEAR. I'm not sure what the DirectX equivalent would be, but it should be pretty similar.

Also, an alternate strategy to one-number switches is to read one character from stdin, then do the cases with character constants: '1' instead of 1, etc.

[QUOTE=calzoneman;33141280]It's probably not a good idea to make your main function recursive. A better way to do this would be to do something like
[cpp]
bool valid_input = false;
while(!valid_input)
{
// switchy stuff here
}
[/cpp][/QUOTE]How do I put that in my function? This is C, by the way.

Although if the switch is intended to continue until the game quits a simple while(true) would suffice

I'm working on a screenshot program, a bit like ZScreen, in C#. This is the class I'm using to implement a global keyboard hook: [url]http://pastebin.com/WNESf0Va[/url]

The problem is that it doesn't allow others to handle it. I'm registering printscreen, but the clipboard doesn't contain an image when I press it.

I could do two things:
[B]1. [/B]Find a way to pass the message through so that Windows [B]does[/B] save the image to the clipboard, or
[B]2. [/B]Take a screenshot myself using Graphics.CopyFromScreen.

I want to know if people mind if I take option 2, if it makes any difference. If it's better to use the clipboard, I need to know how to do option 1.

[editline]6th November 2011[/editline]

Actually, it doesn't matter. I have to set the clipboard to text afterwards anyway. :v:

How the f...reak does it say theres another page, without there actually being one?

[b]Edit:[/b]
Nevermind, seems like a bug... When a page is full, it shows like there is a next page even if there isnt any.

I thought that was fixed, haven't seen it happen in a while.

I was just looking through the thread and saw this:

[QUOTE=Edvinas;32976936]I've been having a lot of trouble with this assignment which I have to finish until Friday:
[quote]There are from 1 to x offices in the building, a tablet is nailed on each office door with it's number, each number must have a separate tablet. So, if there are 10 offices in the building, then 11 tablets will be required, if 100 then 192. Write a program which calculates how many tablets will be required for x offices.[/quote]
Anyone got any suggestions?[/QUOTE]

And I thought I'd practice my Python lambdas:

>>> from math import log10
>>> f = lambda x: sum([((n==0) and 1) or int(log10(abs(n)))+1 for n in range (1, x+1)])
>>> f(10)
11
>>> f(100)
192
>>> f(10**6)
5888896

Apparently, this logarithmic digit counting is pretty much just as fast as len(str(abs(n))).

>>> f2 = lambda x: sum([len(str(abs(n))) for n in range (1, x+1)])
>>> f(10**6)
5888896
>>> f2(10**6)
5888896
>>> from timeit import timeit
>>> timeit(repr(f(10**6)))
0.008955676209552621
>>> timeit(repr(f2(10**6)))
0.009411776069782718

Any way to make this a little more efficient while keeping it a short, unreadable one-liner?

How would I go about line clearing in my Tetris clone? All my tetris blocks are made of individual smaller blocks so the removal shouldn't be a problem, but how would I check if a line is full? C# and XNA.

That depends entirely on your implementation.

If you're using simple two-dimensional arrays of individual cells, simply checking if each cell in a row is occupied should be easy enough to do. If it's full, you move every row above the one you want to clear down by one.

So, I'm using XNA and I'm having some trouble with collision detection between my player and the map.

This is how the map is :

[img]http://i.imgur.com/N6lb8.png[/img]

What's the best way of doing collision detection with this type of map?

[robmaister12]

[QUOTE=Richy19;33149287]To change this would I have to change the SFML source?[/QUOTE]

If you're using OpenGL, it's as simple as glBindTexture(GL_TEXTURE_2D, <font texture ID here>); glTexParameteri(GL_TEXTURE_2D, GL_MAG_FILTER, GL_NEAREST); glBindTexture(GL_TEXTURE_2D, 0); for the texture that's storing the text. It's probably just as simple in DirectX, I just have no experience with it so I couldn't give you a code snippet.

I assume you have a variable for the player position that holds the coordinate the player is on. When the player presses a key to move, you check if the new coordinate contains an 1 or an 0. Assuming 1 means you collide with it and 0 means it's just air you can do something like this when the player tries to move to the right (psuedo-code):

if map[posX + 1][posY] == 0 then movePlayer() else fuck you

Im using the exact same way to store the map and I have a function to retrieve the tile at position x,y. Then I do a check on 8 positions of the player: Left top, right top, right middle, right bottom, left bottom and left middle. Should I say more?

x = 1
y = 0
z = 0
for n in range(1, 9000):
	z = x
	x = x + y
	y = z
	print n, ": ", x
	if len(str(x)) == 1000:

What language is that?

[Jookia]

By the whole scanf fiasco, I'd say C.

Have you #included <stdbool.h> ?

[BlkDucky]

Looks like C. Bool isn't a thing in C. I think the standard way of faking it is to use a char.

[Jookia]

Bool is a thing in C99.

This is the best option if you're using a compiler that supports it.

If not:

typedef int bool;
#define true 1
