Part 3-A: Keyboard Input with Allegro

This is a written and video tutorial created to teach the basics of Allegro and SDL as well as game programming in general, while encouraging the newbie to code it out themselves.

This video talks about the functions for getting keyboard input, and a few other notes.

[cplusplusgamer]

Is there something that you can do to say for example fire when I release the ctrl key?

[LusikkaMage]

@cplusplusgamer Yeah, there should be a "key up" like there is a "key down". "Key press" is like key down but I believe only triggers it once, whereas key-down will keep repeating the event over and over.

[MrHankkey93]

ok so,

if (key[KEY_UP]) player.Move(UP);

this means that if the up arrow is pressed (KEY_UP) the person will just move twards the top of the screen right?

and these are functions on their own right?

[LusikkaMage]

@MrHankkey93 player.Move is a function that you will have to write.

[stanmarshk]

will this this work in other compliers than allegro

[LusikkaMage]

@stanmarshk Allegro is not a compiler, it is a library. Allegro handles graphics, sound, input, and other things. This tutorial covers both Allegro and SDL librarys, so check 3-B if you want to use SDL instead.

As far as IDEs go (Integrated Dev Environments, usually mistaken with Compilers), you can compile your program in any C++ IDE or compiler, you just have to know how to set up the library for it.

[LusikkaMage]

Oh, the playlist one is correct, the one in the links is wrong. Sorreh

[LusikkaMage]

Oh sorry. I'll fix that. That was because the original video had an error that absolutely needed fixing so that one is private, the fixed one is public and I forgot to add it to the list. D:

[TreyRust]

"E1V3B: Keyboard input with SDL" is market private? T.T

or is it just youtube having an error?
