The original code was using W, A, S, and D but you had to press Enter each time. Then Netham showed me that thread and that's how I learned to do it, there wasn't anything about recognizing them by letter. If you have something to offer please do.

Just check if it's equal to '<char>'.
'w' = 119d, 'a' = 97d 'd'=100d, 's'=115d.

With a few modifications your first version will compile under Linux but the second version will not because it relies on conio.h which was originally designed for MS DOS. btw try to avoid to avoid system() calls as they are very platform specific. For some of functionality you need though higher level libraries are needed which will require you to leave the console. Part of the problem is just that consoles don't work very well for graphical apps.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)

system(); calls the command line, in whichever system we are. Different systems have different terminal languages (bash, batch, etc).

I never use them unless if my program is supposed to be platform-specific. And what you said about conio.h is also true

I know that system() is relatively Windows specific but for the purposes of my class that is what we are supposed to use for the most part to get the program from just starting, running, and finishing.

Edit:
Code: [Select]
#include <iostream>#include <iomanip>#include <conio.h>using namespace std;void move(int direction,int &x,int &y){ if(direction=='w') { y-=(y!=1); } else if(direction=='s') { y+=(y!=11); } else if(direction=='a') { x-=(x!=1); } else if(direction=='d') { x+=(x!=11); } else {;} return;}void display(int x,int y){ cout<<"*************\n"; for(int i=0;i<11;i++) { if(i+1==y) { cout<<"*"<<setw(x)<<"X"<<setw(13-x)<<"*\n"; } else { cout<<"*           *\n"; } } cout<<"*************\n";}int main(){ int x=6; int y=6; int direction=27; do { move(direction,x,y); display(x,y); direction=getch(); system("cls"); }while(direction!='q'); system("pause"); return 0;}
