C++ Continuing program once entered a value without pressin enter

Question

I am creating a rpg game on c++ (using DEV c++), and I am searching a way, that, once entered a value, the program continues without pressing "Enter".

Answer 1

getch() and other functions which originate from conio.h header should be avoided, because conio, as stated in Wikipedia, "is a C header file used mostly by MS-DOS compilers to provide console input/output. It is not part of the C standard library or ISO C, nor is it defined by POSIX." In layman terms, it is OS dependent, and the header itself is ancient and not supported by all C/C++ compilers.

getchar() on the other hand, is defined in the C++ standard.

getch() used to be the idea, but then whoever uses this will be banished to the deepest layer of hell, tormented by demons and ghouls for the rest of their lives. Seeing that this is new to you, you can give it a try, but again, beware.

After trying it out, look at getchar(), which isn't the exact replacement for getch(), but is 'legal' and should do the job just fine.

All is included in this thread.

Answer 3

The problem is, it can't. Linux and OSX wouldn't compile getch(), and as far as I am concerned, the program will break if executed on those platforms.

Answer 4

Instead of putting "C++" as a topic, you should set appropriate topic like "Program continue run without pressing enter", would make you find the solutions faster.

Answer 5

then I should use stdio?

Answer 6

game user interface.

Answer 7

iostream

Answer 8

Ok, I am using an interface similar to the windows' command prompt.

Answer 9

Nope. It's a dungeon game.

Answer 10

Sometimes our community is ridiculous. ( : If something can't be ported to a digital oven clock, you're cursed forever when you use it.
When something can be compiled with VS and Code::Blocks and used with Windows 7+, Linux and OSX, that's usually sufficient.

Answer 11

Ok. Then it's somehow critical.

Answer 12

I have a trick to use getchar() without displaying. But that's just in case Linux and OSX have something like cls. Then you can clear the screen after every input and render everything again.

Answer 13

Is the value entered into the debugging console or into your games user interface?

Answer 14

Which library are you using?

Answer 15

iostream is used for the debugging console, not for graphical windows.

Answer 16

stdio is just older, it's also for the text console.

Answer 17

What does your game look like?

Answer 18

Is it a text adventure?

Answer 19

@Hatsy Rei Why is getch() bad practice and how is getchar() better?

@Hatsy Rei Why is this considered bad practice?
