Hey guys..

I have to make a final project (sure you've heard alot of "requests")
I have a simple question..

Very simular to this guys:
http://www.programmingforums.org/for...space+invaders

how would I go about making the aliens in "Space Invaders" ALL move to the right, then down, then left, etc..

Heres my code so far:

(Toggle Plain Text)

#include <iostream.h>
#include <conio.h>
#include <time.h>
#include <lvp/string.h>

void sleep(double delay) {

 time_t start_time, cur_time;

			time(&start_time);
			do
			{
					  time(&cur_time);
			}
			while((cur_time - start_time) < delay);
}

int main() {

		  const int rows = 12;
		  const int cols = 6;
		  int g=0;


String Aliens[rows][cols];
int temp[rows][cols];


for(int x=1; x<rows; x++) {
	for(int y=0; y<cols; y++) {

		Aliens[x][y]="~";

		}
	}


for( x=1; x<rows; x+=2) {
	for(int y=0; y<cols; y++) {
		 g++;
		temp[x][y]= g;
		Aliens[x][y]="(^_^)";

		}
	}

		 for(int f=1; f<5; f++) {


				for(x=1; x<rows; x+=6)
					{
						for(int y=0; y<cols; y++) {


							gotoxy(f+1,y);

							cout << Aliens[x][y];


					}

		}

	  sleep(0.5);
	  clrscr();


	}




}

Its only makes the first column move not the 2nd...

I'm kindof stuck @ this code.. I heard you have to like make the aliens "move" to the next array?

if thats so, does simply adding +1 to x and storing a new "alien" in that spot, and make x = nothing. (to give the impression that it moved instead of clearing the screen) the way to go?

any insight would be much appreciated.

Why are you using deprecated headers? And what is lvp/string.h? Is that something from turbo C++ or am I missing something? You might also want to change your indenting, cause this reads very annoyingly.

Yes it is Turbo C++, yeah my identing is bad too ..

lvp/string.h is from my book, no worries bout that.

from what i described above post, does it make sense at all to anybody?

First of all, use a less dead compiler. Use the correct headers, and indent your code properly.

jeremy04 · May 22nd, 2006, 7:37 PM

Ok I will do that. Like I said, I'm not too sure about the concept of programming this game.. you know like the strategy part. what would I be better off using ,arrays or structures? or both perhaps.

If all of your aliens are kept in an array, simply loop through the whole array and change the variable(s) that is responsible for the x,y position.

Use std::vector and iterate (std::iterator) through it.
