C/C++ :: Creating Moving Objects For 2D Game
Oct 21, 2014I'm working on designing a game in C++ that is similar to the "find the ball under the cup" game. I have a Sonic the Hedgehog icon (weird I know, but it was the first thing that came to mind) that will be hidden underneath one of three rectangular blocks.
Here is how I envision this working:
On the main menu I have 3 buttons which represent 3 different difficulty levels
Easy- blocks move 3 times at a slow speed
Medium- blocks move 5 times at a slightly faster speed
Hard- blocks move 10 times at a fast speed
When the user clicks one of these buttons they will be taken to the game screen.
Sonic will be displayed for 3 seconds and the user will then see him be covered with one of the three blocks.
The three blocks will then move in a random pattern along the middle of the screen at the speed and number of times associated with the button that was pressed.
Once the blocks stop moving, the user is to click on the one they think Sonic is underneath.
If they choose correctly, they'll be taken to a "Winning Screen" that displays a congratulatory message and 2 buttons. Play Again- returns the user to the main menu and the game starts over with a new random pattern. Quit- the window closes.
If they choose incorrectly, they'll be taken to a "Losing Screen" that displays a "Try Again" message and 2 buttons that have the same function as the buttons on the winning screen.
I have never worked with any kind of graphics before other than in HTML and Javascript. I have managed to create the main menu, but how to do the actual game portion of the project. I've been trying to take it a step at a time, (for example, I first figured out how to set the background color for the console window, after I got that right I figured out how to add buttons) but the rest of this seems to depend on each other.
Here is what I have so far:
Main menu:
#include "stdafx.h"
#include <iostream>
#include <Windows.h>
using namespace std;
class MainMenu
[Code]....
So I've got the screens pretty much designed now (with the exception of the game screen itself) but how to tie everything together.
In case my description wasn't too clear, here is a game that I found on Google that is pretty much exactly what I'm looking for. [URL]
C++ :: Game Design Practice For Accessing Container Of Game Objects
Dec 21, 2014I'm working on my first video game. So far I have a few classes in the game starting with the Game class which includes a list of GameObjects (another class). There are several classes that inherit from GameObjects used to implement things like bullets, explosions, various enemy types, etc.
The game essentially iterates through the list of GameObjects to update/render them. I would like to provide access to the Game's list of GameObjects inside another class (like the Bullet class) so I can put new objects on the list. For example, when a bullet hits, I want to add an explosion to the Game's GameObject list it can be updated/rendered.
How this should be setup? I was considering adding a pointer to the Game or GameObject list to the GameObject class (and methods to access it), but I was wondering if there is a better way to set this up?
C# :: Getting Properties From Different Classes / Objects
Feb 26, 2015I have startes making a game where there is 3 ships that cross the screen verticaly, and the point is to shoot them down. So far I have actually managed to do this. I have also managed to add gamescore to the ships. But here is my problem, I cant find a way to combine the score from all three ships in to one score. I have all three ships in different classes, is that wrong? When I try to combine the scores, ship score1 cant see the other scores.
Do I need to somehow have all the ships in one class. Or are there a way to read the scores from three classes, and adding them up in to one in a new class?
One of the errors I get is "the name 'score1' does not exist in the current context.
C# :: How To Define Objects Within Classes
Oct 7, 2014When are you creating fields/properties for specific classes and when you are not doing it but creating them inside just lets say straightaway inside some methods within that classes. I mean if i got class where inside i want to create instance of some other class and then pass this instance to another class - should i create a field for it within class i am doing this operation or not? I was always reading that you create field/properties when its belong to class itself. So if i want only to create some instance outside class i am working and pass it to other class and this is not exactly the part of this class shouldnt i create a field for it and just create it inside method?

Apr 9, 2013Code:
class A
{
public:A(int a, int b);
};
I need to have an object of class A that doesn't have a default constructor in another class, B:
Code:
class A; //This is in a separate header file
class B
{
private:A a;};
The problem is that it won't compile without a default constructor. I'm not allowed to define a default constructor, and the A object in class B has to be private so I can't initialize A a in public.
I also can't change the prototype in the interface to something like
A(int a = 0, int b = 0);
since one of the requirements is that if an object of class A is declared in main, it must not compile due to not having a default constructor. So what can I do to make class B work and compile?
Another question I have is why is this valid:
Code:
class A; //#include "A.h" is in the implementation file so it compiles.
class B
{
private:A* a;}; But not this: Code: class A;
class B
{
private:A a;};
This is for a project that I probably won't be able to turn in on time, but I care more about how to do this right than turning it in for full points.
C# :: Generating Objects Via Arrays From Classes
Jun 26, 2014Here's the problem. I want to generate an array of objects from classes.
brick[] tile = new brick[5] // originally wanted an array of 500 to play with but I thought I'd start small first
I wanted to make a draw() function in my "level01" class to generate a map (so I wouldn't have to build them in photoshop then manipulate rectangle bounding boxes). I tried several things...
First, I found a thread that worked to get rid of the null value in the array ("not set to reference of an object" error).
After that, within a for loop, I tried to initiate my values...
for (int i=0; i < tile.Length; i++) {
tile[i] = new brick(); // calling the object
piece[i] = new PictureBox(); // calling the object's container
//tile[i].brick1X = 38; // already had a default set to it so I commented this out to see if it made
// any difference... it didn't
tile[i].brick1Y += 32; // if this worked, it would have drawn a 32x32 tile down the Y axis every 32
// pixels
[Code] ....
In my Form.cs, I declared my first level map as:
level01 L01 = new level01();
Under the form's constructor, I instructed it to
L01.draw();
so that it would initiate on the game screen.
Needless to say, I get the game screen and the frame, the menu bar I have pops up. But, no tiles.
I even went so far as to get rid of the null values for [i] in the array (using the above for loop but with fewer tasks within the loop) and created a counter that would count up += 1 every time it would make an object.
if (counter < 5) {
And would put in the above tasks inside of the logic loop. I would either get nothing drawn on the screen or it would throw an exception.
I could easily make this using XNA Game Studio in Visual Studio 2010 but I'm using VS2013 and wanted to do a program straight in C# instead of using XNA.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

C# :: Creating Custom If Statement Classes?
Jun 19, 2014I've been working on a project for a few days now, and within this project I need to have a class system that can function similarly to an if statement. The problem I'm having is I can't seem to find any good information on the order in which if statements process the information within it. I understand that if statements process whatever's in parenthesis first, but my question is that when their are several booleans of equal value, for example: "if(x == 1 && y == 2 || 3 == 4 && 4==6)", in what order does it process these true or false statements? (The actual content of the example is superfluous).

C++ :: Implementing Classes And Creating A Driver Function?
Nov 30, 2012For this problem, you will design and implement 2 classes and then write a driver function to test these classes. The first will be a C++ class for an abstract data type color with a public enumeration type colorType that has the color values shown in Listing 10.8. Your abstract data type should have an attribute for storing a single value of type colortype and member functions for reading (readColor) and writing (writeColor) a color value as well as setting and accessing it. The function readColor should read a color as a string and store the corresponding color value in the value attribute of a type color object. The function writeColor should display as a string the value stored in the value attribute of a type color object (see Figure 7.5). Modify class circle and the driver function in Listing 10.9 to include and use this class. You'll need to remove the declaration for color in class circle. Test your modified driver function with the new color and circle classes.
The second class will be to design and implement a rectangle class similar to class circle. Be sure to incorporate the new color class you have written and tested in the first part of the programming exercise. Write a client program that asks the user to enter a shape name (circle or rectangle) and then asks the user for the necessary data for an object of that class. The program should create the object and display all its attributes.
The circle class .h and .cpp files as well as the original driver function will be supplied. You are to provide the .h and .cpp files for the new color class and the modified driver function as well as the .h and .cpp files for the rectangle class and the client program that uses all three classes.
What I have so far, and I'm pretty lost;
color.h
Code:
Code:
//color.h
//Color class definition
#include "stdafx.h"
#ifndef COLOR_H
#define COLOR_H
class color {
public:
enum colorType {black, blue, green, cyan, red, magenta, brown, lightgray, nocolor};

C++ :: Creating Objects Dynamically?
Nov 11, 2013How would I implement a way that i could create as many objects as the user wants?
Let's say every time a user clicks space bar a new cat object would be created, because right now i create lots of objects without initializing and every time i get a input i assign values to the object, the downside is that is limited for the amount of objects i create.
As well i don't want to cause a memory leak, specially in c++ because i need to use the delete keyword.
C++ :: Video Game - Accessing Objects In Another Class?
Dec 3, 2014I am working on a video game that is based on a tutorial I found online and I ran into an issue associated with accessing an object's method inside another class object's function without making the object global which seems bad.
Here is basically how the tutorial set things up in the game: The game has a base class called GameObject then there are other child classes that inherit from this class. The GameObject class has all the basic information an object would have that needs rendered on the screen (x/y position, size of bitmap, bitmap, whether or not it is collidable, etc).
One of the child classes SpaceShip, which is the player so it has attributes and methods associated with managing # of lives and points scored.
There are other child classes of GameObjects in the game that need to take life and add points from the SpaceShip object if they collide with the spaceship or other objects.
In the collision handling routine I basically call a function "void Collided(int objectID)" when a game object collides with another. Within the Collided() routine, there is logic that executes code or other functions based on the objectID it collided with. Some of the collisions require taking life from the spaceship or adding points. The way this was accomplished in the tutorial was with function pointers (see Bullet class constructor and collided method for example). Is this really the best way to handle this sort of thing? It seems like there has to be a simpler way than to keep referencing function pointers in any new class I want to add to the game. I realized this when I went to add a method for the spaceship to fire bullets rather than inside my game class.

C :: Creating Match-3 (Candy Crush) Game Using Arrays
Mar 6, 2015I'm supposed to create a "game" that is similar to Candy Crush or Bejeweled. The assignment takes in a .txt file that contains a matrix of values from 1-5 and then assigns each value to a spot in a [10][10] array. Then an Escape Code function prints out colored pixels in place of the number values for each spot, creating a "game board" looking output. Finally, the program is supposed to look for any matches of 3 same-colored pixels and replace them with a white pixel and "XX". Then the program prints the corrected game board with the matches X'd out.
I have it mostly coded, but I've encountered a couple of issues.
1.) I am supposed to label the columns and rows 0-9, and while I have no problem coding the labels for the columns using printf( ), when I try to print the row labels I get a random string of numbers.
2.) I replaced the matches with white pixels by reassigning the value in the array to 7, for which the ANSI Escape Code is white. However, I'm unsure about how to print the "XX" in the same spot.
Here is the input(.txt) file and the output of the program so far:
And here is what I have coded at this point:
Code:
#include <stdio.h>
void printEscapeCode(int c);
int main(void)
{
/* Declare an image array to be gameboard */
int gameboard[10][10];
/* Declare variables and load in how many rows and columns */
int Nrows;
Nrows = 0;
