Circular Tetris
|
I made this as part of an extended project for school. It is a game of tetris but in a circular fashion.
I'm 17 and applying to University to study CS which I am very much looking forawrd too. I learnt a lot from this project and it's also my most... |

Quick sort algorithm producing "hairy" results
|
I have written a quick sort function but when I compare the elements in the stack to the time taken I am getting very hairy results, it's easiest shown with a picture:
Few elements
Lots of elements
It is sorting a stack of doubles in the above... |

SDL TTF not working on some machines
|
I am using SDL_ttf to create a texture containing all characters from ' ' to '~' and storing each letters position; this renders fine on some machines but on others instead of seeing the text I just see a white quad where the text should be... |

Inheritance and iterators
|
I have 2 classes like so:
class Shape
{
public:
int width, height;
virtual int area() { return 0; }
};
class Square : public Shape
{
public:
int area() { return width*height; }
};
Then I have a vector defined like so:

Circle at rest on a line
|
I have written the code below that works out if a circle is touching a line and if so it "bounces" the circle, it works fine except I'm having trouble removing a couple of bugs.
When the circle is at rest, it slowly sinks through the line. I can p... |

Rotating a vector
|
I have 2 vectors, a which intercepts with c. I am trying to find the vector b (See picture)
Here's what I'm doing atm:
θ = cos-1 ((a.c)/|a||c|)
let x = ax and y = ay
bx = x*cosθ - y*sinθ
by = x*sinθ + y*cosθ

3D Circle-point collision
|
How would I check if a point is inside a circle in 3D space?
I can't do a check to see if the radius is <= the distance between the point and the centre of the circle because this would be a spherical check.

Making a square "wiggle"

I want to make all 4 sides of a square wiggle, the best way I can describe this is like a snake.
I'm not too sure how to go about doing so though.
My rough idea is something like:
let
m = time to do one wiggle
t = the current time

Global array losing values and being filled with default values

I am filling a global array with 12 vectors using an overloaded constructor, but the global array seems to lose it's value and get filled by 12 vectors using the default constructor somewhere along the line.
There is another global array right aft... |

Compiling on Vista-64bit

I am having trouble compiling with Visual Studio Express 2008 on Vista-64bit.
I read that I must configure VS to compile for 64-bit but I did not have this option because that option is only available with the commercial version. I found... |

Circular Tetris

I've updated it (finally).
Download the updated version here
You can now hold down the s key and pieces have their own unique colours.
Sorry it took so long; school got in the way.

Why not just use the standard library sort?
It is for learning purposes.
Quote:Original post by HodgmanWhat's wrong with these results? The zig-zag seems to be because you're rounding to the nearest millisecond.

1.) The 'S' key needs to be fixed as already mentioned.
2.) Each piece of a Tetris board has a distinct color. Their colors are not random: Tetris info

Circular Tetris

The rotations feel weird because of the fact that a piece's width isn't the same as it's height.
Yes, it's hard to play when you first start but once you learn the pieces and their rotations it gets easier. (it was extremely hard without the... |

Application not showing?
|
Try adding this before your return statement:
std::cin.ignore();
std::cin.get();
This causes the program to wait for input before it proceeds to the next step.
As a side note, there are alternative ways of doing this like system("pause"... |

Sorry, I wasn't sure whether I could post the code or not and I guess I kind of assumed that by saying "texture" you would know what I meant because to me it's obvious but that's because I wrote the code. I'll remember this.
