Ok, so what I'm trying to do (and tell me if this is utterly stupid) to handle input in my game is handle all the events in the Input class, then pass an array of events to the handler (in this case Engine)
What I'm basically doing is checking for keypresses, mouse events, etc. and adding them to a vector to be passed back.
What I'm currently trying to do is make a struct:
| Code: | struct m_key
{
bool m_pressed;
int m_key;
}
and
struct m_mouse
{
int posX;
int posY;
bool leftDown;
bool middleDown;
bool rightDown;
} |
that way, i can handle structs in my input class and have the other classes deal with the input (I'm adding these structs to vectors as they are added because I want to know the order of the keys (for console input in-game)
Or is this a totally bad Idea? I'm trying to keep my classes as separate as possible, so Input has no interaction with anything else, but it's becoming increasingly difficult.
Thanks in advance,
Jason

You should use the boards' search function. Someone already posted a thread about this. ( http://forums.rpgdx.net/viewtopic.php?t=1521 ) Seeing as this person seems to be working on a very, very similare project as yours and had the exact same problem in that thread, many posts already made there will apply to your current dillema. Posting there would prevent having people reiterate what's already been said.
Just sayin'.
Anyhow, how is this handled? Do you update the states in an array of keys or just run through this vector to figure out which state a key is in? If it's the latter, yes, that's a bad idea.

From your previous post I gather that you're using SDL, SDL provides event driven input, you should use it. At least if you got any plans on actually building a robust input system that won't end up a horrible kludge.
Here's a simple example: http://www.libsdl.org/cgi/docwiki.cgi/Event_20Examples
