The Dink Network

hey ive set up variables
make_global_int("&Blood", 0);
make_global_int("&Fingerprints", 0);
make_global_int("&Witness", 0);
make_global_int("&Thread", 0);
make_global_int("&Dagger", 0);

and used them like this
&Blood = 1;
and made them change things like this

void talk(void)
{
freeze(1);
freeze(&current_sprite);
say_stop("Hello",1);
wait(200)
say_stop("`6Hey Dink You Made It!!", &current_sprite);
wait(200)
say_stop("Hey",1);
wait(200)
say_stop("`6SimonK Is Under A Rock", &current_sprite);
wait(200)
say_stop("Hmmm",1);
wait(200)
say_stop("`6Can You Catch The Killer", &current_sprite);
wait(200)
say_stop("Sure!",1);
wait(200)
say_stop("`6Also Kory Has Been Acting Odd", &current_sprite);
wait(200)
say_stop("`6And ThinkDink Has Been Asleep For Ages", &current_sprite);
wait(200)
say_stop("`6I Gotta Go", &current_sprite);
wait(200)
say_stop("Ok ",1);
unfreeze(1)
unfreeze(&current_sprite);
}

if (&Blood == 1)
if (&Fingerprint == 1)
if (&Witness == 1)
if (&Thread == 1)
void talk(void)
{
freeze(1);
freeze(&current_sprite);
say_stop("Hello",1);
wait(200)
say_stop("`6Hey Dink Whats New", &current_sprite);
wait(200)
say_stop("I Found Some Evidence",1);
wait(200)
say_stop("`6Let Me See", &current_sprite);
wait(200)
say_stop("`9*SHOW EVIDENCE*",1);
wait(200)
say_stop("`6Wow!!", &current_sprite);
wait(200)
say_stop("Yup!",1);
wait(200)
say_stop("`6So Its **Not Telling Till Dmod Out**", &current_sprite);
wait(200)
say_stop("`6Well We Are Sending Him To Prison Thanks", &current_sprite);
wait(200)
say_stop("`6 You Helped Loads", &current_sprite);
wait(200)
