#4837116 [C++] Saving, Loading & Reading .txt Files Into Arrays

Posted by zacaj on 18 July 2011 - 06:24 PM

using a #define replaces anywhere you put the first word with the second.  So when you write
items[SHOVEL]=1;
youre really writing
items[2]=1;

I think youre not completally understanding arrays...  Ill try to explain, but you might want to read some more tutorials on the subject.  Also, sorry if any of this seems stupid-obvious, but its hard to get a feel for how much you get online.
Arrays are just a whole bunch of single numbers
int array[5]; is equivilant to
int array1;
int array2;
etc.
But, you can use a variable (like int i) to access a certain one of the variables in the array.
So you can do array[i]=1;
instead of having to say
switch(i)
case 1:
array1=1;
breakl
case 2:
array2=1;
So, you can just use for loops to access each member(individual element) of an array based on the variable you use in the for loop (im assuming you know what for loops are)


#4835294 Help Running OpenGL 4.0

Posted by zacaj on 14 July 2011 - 09:28 AM

Most vm software just gives access to the origional hardware, so I dont think that will help.


#4832640 How do people stand Java?

Posted by zacaj on 07 July 2011 - 10:30 PM

Had to take a college course on it, and hated every minute of it.  I cant see how they thought some of the stuff was a good idea.  The only satisfaction I get from java is bending its bad design to act like C++, confusing the professor constantly.  Especially operator overloading, and not having [] for vectors/strings.  Really?


#4832219 Setup OpenGL like Direct2D

Posted by zacaj on 07 July 2011 - 05:37 AM

As to the direct2d part of the question, you should be able to use a different base matrix, right after you set the identity matrix, to do this.  In the case of openGL, I think you could just negate the y column of the identitymateix to achieve axes like direct2d, then translate down and left half your screen width so that the origin is in the corner.


#4824606 Include content in emails

Posted by zacaj on 17 June 2011 - 02:54 PM

Itd be really helpful if when I get send an email saying theres a reply to a topic Im watching, it included what was posted.  New posts already do this, I dont see why replies dont


#4823250 Character/model management in a game

Posted by zacaj on 14 June 2011 - 09:40 AM

You only need to store one copy of the model data for any amount of models, then you can just change the transform matrix for each one.
What do you mean by pickable?
You might also want to look into instancing for newer graphics cards


#4817247 Using SDL for OpenGL context is slower than GLFW

Posted by zacaj on 29 May 2011 - 03:34 PM

My engine isnt using FBO's yet, but when I did a quick speedtest before starting I found SDL to be MUCH faster that GLFW


#4815286 Creating a noise texture with pre-defined values [Need help with kriging algo...

Posted by zacaj on 24 May 2011 - 02:20 PM

You could try using Kriging (http://the-witness.net/news/?p=345) on the black holes, and adding other random control points for the field.  Ive never actually used it, but it seems like it would work...
