char_on_spot...?

[Donald Hebb]

This script does nothing:

 

Code:

beginstate 31;if(char_on_spot(19,36) == 0 || char_on_spot(19,36) == 1 || char_on_spot(19,36) == 2 || char_on_spot(19,36) == 3){print_str("You are standing on the mat.");}else{print_str("You are not standing on the mat.");}break;

If I'm merely making some stupid syntax error, then please alert me.

I think you may need parentheses around each condition, but I'm not sure:

 

((char_on_spot(19,36) == 0) || (char_on_spot(19,36) == 1) || (char_on_spot(19,36) == 2) || (char_on_spot(19,36) == 3))

Nope- Doesn't work.

[Namothil]

Looks like it should work. Did you make sure the state is actually being called? (Put a print_str outside the conditional.)

[Donald Hebb]

I tried both Namothil's and Wizard's suggestions, but still couldn't make it work. Bah.

 

(First, I tried calling this through state 2. Then, I tried calling it as a node. Both didn't work.)

Try incrementally checking it.

 

good = false;

good = (char_on_spot(19,36));

if (good = false) good = (char_on_spot(20,37));

if (good = false) good = (char_on_spot(20,37));

if (good = false) good = (char_on_spot(20,37));

 

if (good = true) {

// on mat

 

Etc.

[Donald Hebb]

Boolean checks don't use semicolons.

 

That aside, I'm not entirely sure what you're getting at.

It works like this.

Good is false.
Good is whatever char_on_spot returns (i.e. true if char there, false otherwise).
Then, if good is still false, it sets good to whether char is on the next spot. And again and again until it's tried all the spots. Then you check good, see if it's true, if it is, a char is on any of the spots.

Try making it print the result of is_char_on_spot.

Put a space between the if and the first parenthesis. I don't know if the space matters, but its worth a try.

It is a good idea to check out the tech support page page, as I and others have been sending all these issues to Jeff.

This is a bad documentation bug. There are two functions, each of which is poorly documented: char_on_spot() and char_on_loc(). The function char_on_spot() is NPC only. You are clearly checking for player characters here.

Change it to char_on_loc().

[Walker White]

One more thing. To make it a little more efficient, you want to write (now that I know the UBB for code)

 

Code:

beginstate 31;if (char_on_loc(19,36) >= 0 && char_on_loc(19,36) <= 3) {    print_str("You are standing on the mat.");} else {    print_str("You are not standing on the mat.");}break;
