I just had to let you know that this is EXTREMELY helpful.

An actual working simple example! That seems to be odd around here.

CuteAlien, Basically I went about writing my own FPS camera for two reasons: 1. To help learn 2. I cant stand the way user input is not separated from the included cameras. Anyway, I can get a basic camera moving around but you attach to a collision response animator and it simply goes nutty wheneve...

I have been trying to get a basic camera to work for a week now and finally tried this on something I saw posted from 03.. To my surprise it actually works. The camera will move in whatever direction it is facing.. Ok great! How does it work?? Edit: Nevermind.. Works in space find but you apply an a...

Does anyone know a good resource too help learn generalized vector information..? Basically any good tutorial on vectors, matrix's etc

I completely agree it would be easier to use STL as much as possible. Unfortunately Ive wasted today and the better part of yesterday trying to figure out comparative operators for things such as sort and equal_range. I could never seem to get the compiler to actually work with an example such as yo...

Saturn, I think it boils down to I understand how to do work with simple things such as [] - You start talking adding comparative operators into a template and I am lost. Anyway, once I figured out I could use [] it took 10 minutes to solve. Should be pretty efficient I think. Time to do some tests ...

Saturn, That would be very slow compared to a binary search algo. Imagine something with 1000 objects - it would take on average 500 times to find the correct object doing a linear search. Using binary would only take 10 at most.. CuteAlien, Em - learning that makes me want to cry. I can actually im...

int a = 123; std::lower_bound(bleh.begin(), bleh.end(),a, Test()); I know four arguments should be used. I just can not figure out for the life of me how you would get it to actually take the number into the third argument. It comes down to I am lost when it comes to using operators in the various ...

CuteAlien, That wouldn't work as the algo would never stop. pseudocode algorithm: WHILE low is smaller than or equal to high SET midpoint to (low + high) / 2 IF data2Search is equal to data[midpoint] THEN return midpoint ELSEIF data2Search is smaller than data[midpoint] THEN SET high to midpoint - 1...

Two Part Question! #1 Is it possible to get binary_search to actually return an iterator instead of just true or false? The way various documentation explains it all it does is return true if the value is present. Well, thats kind of useless! #2 If binary_search is useless... How can one do math on ...

Thank you for the examples cutealien and saturn. Your examples helped me figure out the correct syntax after about 10 frustrating hours for trying! Hopefully Ill never have to use a sort algo again as I really don't understand the concept and have no more desire!!

Thanks Again,
trixs

Thanks for reply!

Yes, they should be declared public. I just forgot to put public: when I wrote that example. Could always use a struct and not worry about it though.

Anyway, unfortunately thats not the issue. Although I wish it was!

Hi, I am having troubles with sort in C++.. Have been trying to get this to work for multiple hours and am getting no where. I do not understand how to actually get the sort algorithm predicate function to work. Anyway heres an example of what I am trying to do: class test { int a; int b; int c; } N...

lol - you forgot the vectors!

Seriously, I couldn't think of a way to keep it simple and functional. How have you accomplished it in the past?
