C++ :: Rogue Like Item Creationg And Optimization
Mar 8, 2013
I'm creating a roguelike/ cave exploration game, and I've created a lot of it, but I am having problems with item creation. The item is supposed to be the '*'. I know what the problem is (I'm setting Dmap to map after creating the item, but before outputting Dmap), but I don't know how to fix it.Also, I don't really know how code optimization works.I'll split my code between this post and the comments:
#include <cstdlib>
#include <iostream>
#include <conio.h>
#include <windows.h>
#include <stdio.h> /* printf, NULL */
#include <stdlib.h> /* srand, rand */
#include <time.h> /* time *

I've been assigned to program rogue using the ncurses library, which will need
1. File I/O
2. String parsing
3. User input (h,j,k,l)
4. Room drawing
And Where i can start with this program?

I've been trying to create a roguelike, and I was trying to create randomly generated rooms like in Rogue. I'm seperating my map array into sections and giving it a 50% chance of spawning a room, but right now it doesn't do anything but spawn solid rock. What am I doing wrong?
int MapSizeX = 100;
int MapSizeY = 100;
char map[100][100] = {};
char wall = 178;
int ViewDistance = 10;

I have two menu items. When item 1 is disabled, I want item 2 to be disabled as well. In the OnUpdate handler of menu item 1, I have tried to use "t_pMenu = pCmdUI->m_pMenu;", "t_pMenu = pCmdUI->m_pSubMenu;" and "t_pMenu = pCmdUI->m_pParentMenu;" but I always get NULL t_pMenu. How can I achieve this purpose?
Code:
void CDummyView::OnUpdateMenuItem1(CCmdUI* pCmdUI)
{
if(m_bShowMenuItem1) {
pCmdUI->Enable(TRUE);

I could not find anything I could understand on this, so I have heard that -O3 option may reduce the numerical accuracy of doubles. Is this true?

Can these loops can be optimized?
#define C_SAMPLEPOS(channel) (channel->sound.position)
#define C_BUFFERSIZE(channel) (channel->sound.numsamples)
#define C_BUFFERINC(channel) (channel->bufferinc)
//Use precalculated sample positions!
[Code]....
Should I change the inner loop (checking active channels and if they're valid) to the outer loop?
So the outer loop checks if the channel is valid for use, The inner loop checks and increases the current relsample The inner loop adds the sample to the mixer.
When the outer loop finishes: The outer loop clips all samples.
Would this be faster than the current method? (so instead of a:
for (sample=0;sample<4096;sample++){for (channel=0;channel<66;channel++){/* Process channel here */}}
We get:
for (channel=0;channel<66;channel++){for (sample=0;sample<4096;sample++){/* Process sample */}})

I want to disable optimization in Visual C++ 2010. In gcc on Linux I could just use the -O0 switch, but in Visual C++ 2010 there are two categories of optimizations, one in the C/C++ pane and the other in the Linker pane:
Attachment 33229
So what settings should I choose to make sure that no optimization is being performed?

Recently I was looking into embedded programing of AVR microcontrollers.
At this site [URL] ....
I have encounter some code that implements delay
asm volatile ("nop");
From what I understand it is assembler code that creates delay - one processor clock long.
For C/C++ language it should be like ; or {} = null statement.
Now my question is how to implement this C/C++ code and prevent my compiler (WinAVR: AVR-GCC) to delete this command during optimization (-Os or -O2). Or is it simply better to use the assembler function.
I know I can use for-loop
volatile uint8_t foo
for(foo=0; foo<2; ++foo){}
but for that I have to create a variable = wasting 1 byte of RAM; correct?

I have tried to implement a much simplified version of boost::compressed_pair.What follows is a partially specialized EBO_pair<T1, T2> class template, written in C++11.The first type T1 is constrained to not be empty.The second type T2 may or may not be empty.
#pragma once
#include <memory>
#include <type_traits>
#include <utility>
namespace dsa
}
[code]...
Edit: added non-member swap() function template.

What the code below is not doing is returning a value for item to my variables (item1, item2, etc..) I'm not sure how I can make a function prototype that will ask for input and basically recycle after going through the program to a new value for each item. I also need to input individual tax for each item. I will also post it in this message:
double tax, item,salesTax;
double cost(double);
double CalcSalesTax(double);
main(){
double total,item1, item2, item3, item4, item5, tax1, tax2, tax3,tax4,tax5;

I'm having a problem with removing an item from a queue. At first in the debugger I got SIGTRAP but I don't get it anymore but the problem still exists. When you try to remove an item from the queue the first nothing happens. Here's the code below compile it and you see what I'm talking about.
Code:
#include <stdio.h>
#include <stdlib.h>
struct Node {
char let;
struct Node *nextNode;

If the item is in the array. Count how many times it is stored in the array and what are their respective array locations.
How can I add this output in my program.
Here's my code...
int array[15]={28,3,16,4,3,16,5,8,4,12,5,4,8,21,40};
int x=0;
int done=0;
int item;
cout<<"Input an item to be searched:";
cin>>item;
[Code] ....
This should be the output:
Item to be searched: 4
number of occurence : 3
array locations : 3 8 11

How can I get the items from a list into textboxes. I am doing an windows form application in visual studio.
I have the first form with a couple of textboxes.
I want the inputs be saved in a list. And then displayed in another form. How to move on. The class with the list looks like this:
public class Casecs {
public List<caseInformation> fallInformation = new List<caseInformation>();
public class caseInformation {
public string caseId { get; set; }
public string phoneNumber { get; set; }
public string description { get; set; }
}
Then the form with the inputs in textboxes looks like this:
Casecs Casecs = new Casecs();
Casecs.fallInformation.Add(new ERIS.Casecs.caseInformation {
caseId = txtCaseId.Text,
phoneNumber = txtPhonenumber.Text,
message = txtMessage.Text
});
Then where I am stuck a form with some textboxes where I want the list items to be displayed:
public partial class btnDispatch : Form {
public btnDispatch() { }
public btnDispatch(List<Casecs.caseInformation> fallInformation) {
InitializeComponent();

I have made a menuitem using the combo box, but when I add items in like in the image below:
[URL]
My problem is that when I move my mouse over the item it displays this darker box around the text:
[URL]
This stops me from clicking it and the code from being executed.

I have a C# WPF program that takes a SQL query and populates a column from an Oracle database into a listbox on the form. I would like to be able to compare all items populated in the listbox, and run a SQL query for each item, populating those values into a different listbox.
So far, I have this code:
string sql2 = "select unique apps.fnd_application_all_view.application_name, fnd_responsibility_vl.responsibility_name, fnd_form_functions_tl.user_function_name, fnd_form_functions.function_name, fnd_form_functions_tl.description, fnd_form_functions.type FROM fnd_compiled_menu_functions, fnd_form_functions, fnd_form_functions_tl, fnd_responsibility, fnd responsibility_vl, apps.fnd_application_all_view WHERE
[code]....
I would like to be able to basically take the "Responsibility_Name" value from the first listbox (lstResponsibilities), which is already populated, and use those values to in the "sql2" query to find the "Function_Name" and populate "Function_Name" in the second listbox (lstFunctions).

v.push_back(14);
v.push_back(32);
vector<int>::iterator next;

I used VB6 before to output file.
I set my output to file to tab(20) or tab(45) respectively.
In C++, how do I do this?

I am trying to write a function that inserts an item into this binary tree in C++.
template <typename T>
struct BTree {
T val;
BTree<T>* left;
BTree<T>* right;
BTree(T v, BTree<T>* l=nullptr, BTree<T>* r=nullptr) :
val(v), left(l), right(r) {}
};
Here's my attempt.
template <typename T>
void insert(BTree<T>* tree, T item) {
if (tree == nullptr) {
tree = new BTree<T>(item);
} else if (item < tree->val) {
insert(tree->left, item);
} else {
insert(tree->right, item);
} }
I think this function may not be working because I am modifying `tree`, which is a local variable. How do I actually modify the current pointer that `tree` represents, not just `nullptr`?

I have ploughed through the exchanges in all the forums, yet I still cannot make it work. The following is a tiny Code::Blocks program, written to isolate the problem:
// resource.h
#define IDR_MYMENU101
#define ID_FILE 102
#define ID_DISABLE103
#define ID_ENABLE 104
#define ID_MESSAGE105
#define ID_EXIT106
[code].....
case ID_ENABLE is similar to case ID_DISABLE above, and neither works. case ID_MESSAGE and case ID_EXIT both works as expected.I have tinkered with EnableMenuItem(), but without success.

In my program, I am trying to implement a set in which I can add/remove and print, it doesn't have to be a specific value removed just that it removes an item from the list. When I call the removeItem function it crashes, saying my iterator is out of range. I don't understand what is wrong. Here is my code:
#include "stdafx.h"
#include <iostream>
#include <set>

I need to select a random item from an array but I am going to have more than 1 such array so I created the random value selector as different function. Right now I am getting a correct value for random function but when I try to access the array value associated with that index I get 2 digits which does not make any sense.
#include <iostream>
#include <cmath>
#include <ctime>
using namespace std;
int randFunction(int size);
int main() {
int heapsize;

Basically, the program is just sort of a soundboard. The way it is now, it just reads all the names of the files in a particular folder (all .wav files), and then adds an entry to a listBox for each file found. What I would like to do, is instead of a listBox, have buttons for each one. Is there any way to iterate through a list of items and create a button for each one? The main problem I see is placing the buttons. It would have to have some sort of grid to place them in I would imagine...
