The great mystery

All these guesses are way off except for one, and I don't know how you knew this.

...serial bedwetter...

When I was about 24 or so I had a lot of alcohol to drink and I wet my bed. I ........ed myself, and now I wear diapers. lol.

>All these guesses are way off except for one, and I don't know how you knew this.<

I know a secret. I was watching you through an
obscure portal on the old board. Why do you
have a heart with Mother written on it tattooed
to your butt?

>-Dean is a robot, that was hacked by Microsoft programmers- and reprogrammed with pro-Microsoft stuff

haha funny Microsoft couldn't Hack there way out of a wet paper bag...

i think/Hope Sunlight will return someday so i can finally end the OpenGL vs. Direct-X debate once and for all...

cause i could...

BTW: im pro OpenGL.

I don't know but I just noticed that, you're right! I remember once I had a teen girlfriend, I was about 20 at the time, anyway, she convinced me to dye my hair straw blonde. I wouldn't normally do these kinds of things but she got her tounge pierced and did all kinds of stuff, she was also into witch craft and some goth stuff. Anyway I guess it somehow made me a rebel now.

>> 1. Must press key for input (no holding it down)






I'm little confused but if I interpret correct, I had to do something

similar to this to create a sliding motion with the mouse.


Because

you can detect when a key goes down and when it comes back

up you set a state variable perhaps the objects velocity etc.

Once the key goes up you can set it to 0 or whatever.

Code:

SDL_Event event;





unsigned char key_state;











enum {





    RIGHT_KEY_PRESSED = 0x0001,





    LEFT_KEY_PRESSED    = 0x0002,





    UP_KEY_PRESSED       = 0x0004,





    DOWN_KEY_PRESSED  = 0x0008





};











/* ... */











while(SDL_Poll(&event))





{





    switch(event.type) {





    case SDL_KEYDOWN:





              switch(event.key.keysym.sym) {





               case SDLK_RIGHT:





                         key_state |= RIGHT_KEY_PRESSED;





                         break;





              case SDLK_UP:





                         key_state |= UP_KEY_PRESSED;
                         break;
               case SDLK_LEFT:
                         key_state |= LEFT_KEY_PRESSED;
                         break;
                case SDLK_DOWN:
                          key_state |= DOWN_KEY_PRESSED;
                          break;
                }            
                break;
     case SDL_MOUSEMOTION:

               printf("mouse's x motion: %d\n", event.motion.x);

               printf("mouse's y motion: %d\n", event.motion.y);

               break;

     }





}









if (key_state & RIGHT_KEY_PRESSED) {



       /* do something */



}

If this doesn't solve it a related article is this one

Under "proper game movement"



I don't know about game pads though SDL supports

joysticks. I don't have a joy stick or game pad so it's

hard to test it out.

Not sure why the code as so many spaces.
Anyways you should look at SDL_Event.h it's well commented.

It's obvious to me look at the disclaimer on Sunlight's website

I've tried that already, and the object does not move till you relese the key.


Thanks for the mouse movment, I spent an hour or so tring to figure out how to asign player1.yTop the y postion of the mouse.

Me, as smart as collageGirl nah. I'd rather be smarter, being dummer would be to much work

Well, gamegod3001, for one thing you didn't quote her properly. Maybe you should take a double dose of your medicine today.

>anyway, she convinced me to dye my hair straw blonde. I wouldn't normally do these kinds of things but she got her tounge pierced and did all kinds of stuff, she was also into witch craft and some goth stuff. Anyway I guess it somehow made me a rebel now.<

My number two son fits this description, sort of.
He and his friends, both sexes, died their hair all
kinds of weird colors. A friend of his ate with us
the other night, she had so many pins and stuff
stuck through her eyebrows, I couldn't look at
her. They're weird but they're nice people, too.
The differences between my four children are profound.
None of them comes close to resembling any other;
yet, they all have physical and character traits
identical to one of their parents. Very strange.

LOL

>Well, gamegod3001, for one thing you didn't quote her properly. Maybe you should take a double dose of your medicine today.<
What do I have to use the quote tags?

>Me to, lets pick on dean/witch_craft.
I wrote this before I saw his comment, I must be good.

No, I don't mean useing quote tags. I mean reading more carefully and not inserting words into statements and calling them quotes.

I'll code some stuft with a scarry box that you move around.

Ok here it is, your code is probably not working
because your missing a break statement in the switch
statement where your handling input.

Code:
