The Dink Network

Uhhh... me again. Hey, I warned you I will write often. This time, touch procedure is bugging me. In original Dink, there is an (invisible) desk blocking the path until story reaches 5 or something. I'm trying to make the same, except it should work for the rest of the game.

In a property page, I've set values like this:

Type: invisible
Nohit
touch damage -1

script attached:

void touch(void)
{
sp_touch_damage(&current_sprite, 0);
move_stop(1,8,290,1);
say("The door is jammed! Guess I'll need to find another way out.", 1);
sp_touch_damage(&current_sprite, -1);
}
