Ok, so I'm probably just making some insanely dumb mistake... but for some reason, when this section of the intro is run, it freezes up just after &fire is created.

wait(400);
say_stop("something is said!", 1);
int &fire = create_sprite(200, 271, 11, 506, 1);
move_stop(&fire, 6, 303, 1);
sp_active(&fire, 0);
sp_active(&person, 0);
int &thing = create_sprite(360, 271, 16, 335, 1);
say_stop("some more things are said!", 1);
wait(400);

So, uh, the fireball doesn't move, and the game ceases. It doesn't like hit anything that prevents it from reaching its destination, it just *doesn't move*. Whyfor?

The fire ball needs a timing so it 'animates', and a speed set so it can move.

wait(400);
say_stop("something is said!", 1);
int &fire = create_sprite(200, 271, 11, 506, 1);

sp_seq(&fire, 506);
sp_timing(&fire, 0);
sp_speed(&fire, 6);

move_stop(&fire, 6, 303, 1);
sp_active(&fire, 0);
sp_active(&person, 0);
int &thing = create_sprite(360, 271, 16, 335, 1);
say_stop("some more things are said!", 1);
wait(400);

Thank you. You've half-solved my problem. However, now the fireball just animates in place, but still will not move across the screen to the destination. Yes, I've quadruple checked to make sure that there's no hardness blocking it (I think it's set to move through hardness anyways, isn't it?)... I'm so confused.
