2 Questions on SDL...

One: How do you change the cursor from that odd inverted black one that it makes you have?
Two: How do you get keys to repeat? My keys are like... semiautomatic, one event per press, instead of auto, one press, as many events as you want until you let go. Hold down any key while in a text box, you see how it goes ssssssssssssssssssss? Instead of just s? How do you do this in SDL?

Instead of using events, use the keystate array in your main loop.

You could track the cursor, and then blit your own cursor image to the cursor location (and hide the actual cursor).
I do that a lot when i'm trying out new features with editors.

So, how do I know which key is which in the array? Is there a specific list?
So if I'm checking for up, and its 3rd in the list, would i do *psuedo code*
if(keystatearray[3] == 1){
movecharacterup();
}

RANDOMERRORWTF?!?!?!
Okay... this is really f***ing gay.
THIS code works:
Code: Select all
void initClips(){
for(int y = 0; y <=11; y++){
for(int x = 0; x <= 3; x++){
clip[x*y].h = 32;
clip[x*y].w = 32;
clip[x*y].x = x*32;
clip[x*y].y = y*32;
}
}
}
But this doesn't:
Code: Select all
void initClips(){
int val = 0;
for(int y = 0; y <=11; y++){
for(int x = 0; x <= 3; x++){
clip[val].h = 32;
clip[val].w = 32;
clip[val].x = x*32;
clip[val].y = y*32;
val++;
}
}
}
I did this, because I realized that it would do (0*0,0*1,0*2,0*3,1*0,1*1,1*2,1*3,etc...), instead of what I wanted, just a straight value that increments. Really, wtf is wrong with this?!?

val++; //try this

OH sorry, um, Damn, I actually was testing around, to see if it would work with "val = val + 1" instead of "val++" and I didn't want you guys bitching at me, so I change it to val++, and i forgot the val =... and thats not the error. I dont under-effin-stand! x*y are both ints... and val is an int too

Setup some breakpoints and run through it a few times. The debugger is there for a reason.

You can remove the fullscreen option for debugging purposes.
Anyway, glad you figured it out.

Hmm, now text isn't working: is there a way to draw text without the sdl_ttf extention?

It's basically an array of booleans. And you can use the SDL constants. For example, for the up key:
Code: Select all
if(keystates[SDLK_UP]){
movecharacterup();
}

What size sprites is the ES team using? I'm using 32x32 is that the way to go?
