Bomb Refill Script help

At the beginning of my game, bombs are a bit crucial and I wanted to make sure the character could get a refill without continuing to load up to the max infinitely. I also wanted to try my hand at scripting, this is my first script.

import "std.zh"
ffc script bomb_refill {
    void run() {
    itemclass bombclass = LoadItemClass(IC_BOMB);
        if ( (Link->X - this->X) <= 16 ) {
            if( 0 <= (Link->X - this->X) ) {
                if ( (Link->Y - this->Y) <= 16 ) {
                    if ( 0 <= (Link->Y - this->Y) ) {
                        if (Link->Item[3]) {
                            Link->Item[3]=true;
                            bombclass->Counter[CR_BOMBS]=4;
                        }        
                        else {
                            if (bombclass->Counter[CR_BOMBS]<4) {
                                bombclass->Counter[CR_BOMBS]=4;
                            }
                        }
                    }
                }
            }
        }
    }
}

However, when I try to compile this, it tells me the signature doesn't match for LoadItemClass(float). I've tried using the const from std.zh, as above; I've tried just typing in 27; and because it mentions it as float, I've also tried typing 0.0027. All return the same error. I've also tried just putting LoadItemClass in everywhere I used 'bombclass', but then it told me it wasn't expecting the arrow. What am I doing wrong? I've looked at some code on the forums, I've read the documentation from the stickied thread, but I don't think I've seen an example specifically of LoadItemClass being used. Although CDawg's enemy HP modifier had similar syntax...

I'd just like to know what I'm missing. I've already gone through a lot correcting errors, and learning all the while. But this one has me stumped.

This should fix that problem:

itemclass bombclass = Game->LoadItemClass(IC_BOMB);

One other simple thing I see: I believe you meant to use [font="Courier New"]if (!Link->Item[3]) {[/font] on line 9.

There are a couple of trickier problems that would undoubtedly be quite frustrating.
After you change the function call above, the compiler will complain about how itemclass->Counter isn't an array. That isn't what you should be using, anyway; the number of bombs is stored in Game->Counter[CR_BOMBS]. itemclass->Counter just gives you the array index for Game->Counter (that is to say, bombclass->Counter is CR_BOMBS). So, you don't actually need to load up bombclass at all.

Especially important: you need to wrap everything in [font="Courier New"]while(true) { /* ... */ Waitframe(); }[/font]. Otherwise, it'll only run for the first frame the FFC is on the screen. If Link's not in the proper range immediately, it'll never have any effect.

The script, with those revisions:

import "std.zh"
ffc script bomb_refill {
    void run() {
        while(true) {
            if ( (Link->X - this->X) <= 16 ) {
                if( 0 <= (Link->X - this->X) ) {
                    if ( (Link->Y - this->Y) <= 16 ) {
                        if ( 0 <= (Link->Y - this->Y) ) {
                            if (!Link->Item[3]) {
                                Link->Item[3]=true;
                                Game->Counter[CR_BOMBS]=4;
                            }        
                            else {
                                if (Game->Counter[CR_BOMBS]<4) {
                                    Game->Counter[CR_BOMBS]=4;
                                }
                            }
                        }
                    }
                }
            }
        Waitframe();
        }
    }
}

I'm very happy someone coded this. I've been intending to code up an arrow refilling script for some time now, and have not got around to it. Thanks!

itsyfox 05 Jan 2007, 18:57

Thanks for all the help, Saffith!

Yeah, exactly how to use Counter[] and itemclass->Counter was confusing me a bit. I'm glad to understand it better.

EDIT: I asked about the !, but then I looked again at WHERE it is, and figured it out. Silly me. Thank you!

And, thanks, C-Dawg! I'm glad just posting it for help makes it useful.

Also, it looks like it still didn't update yesterday, but if a mod could delete that other topic of mine...I thought I'd changed the name and contents to ask so, too. My 'net cut out right when I was trying to post, and I wasn't seeing any of the forum's changes until well after they occurred once I got it back anyways, so I thought my post hadn't gone through.

I'll try changing the name and contents again.

EDIT #2:

Alright! Compiled, tested...I wanted it to play the item sound effect, so I added that in too, and also, my position checking was a bit off. Now I've tested and fixed it, and it's perfect.

import "std.zh"
ffc script bomb_refill {
    void run() {
        while(true) {
            if ( (Link->X - this->X) <= 16 ) {
                if( Link->X >= this->X ) {
                    if ( (Link->Y - this->Y) <= 16 ) {
                        if ( Link->Y >= this->Y ) {
                            if (!Link->Item[3]) {
                                Link->Item[3]=true;
                                Game->Counter[CR_BOMBS]=4;
                                Game->PlaySound(25);
                            }        
                            else {
                                if (Game->Counter[CR_BOMBS]<4) {
                                    Game->Counter[CR_BOMBS]=4;
                                    Game->PlaySound(25);
                                }
                            }
                        }
                    }
                }
            }
        Waitframe();
        }
    }
}

Here's an image of it working, too. (Some of the graphics are messed up since I moved tiles around and haven't fixed it yet.)

I didn't use the SFX_ values because the quest file this is built off of is the old newfirst.qst, which doesn't have all the newer SFX. 25 is, at least in that one, the sound for picking up an item. 😊

I'm thinking I'll maybe have it delete the FFC on contact as well, only to pop back up when you re-enter the room...I'm also thinking of disabling the use of weapons on that DMAP, since it's afterall a house. But right now, I like being able to bomb the table and then refill. 😊

Thanks for all your help, Saffith!

Sidenote: They said the raft thing was fixed in beta 16, but it isn't! I'll have fun playing with scripts in the mean time, but my quest is on hold right near the beginning waiting for the raft back. 😞 Maybe I'll do a script for that, too, although I'd have to basically duplicate the exact workings of the raft (down to following raft flags) for my raft mini-game to work properly...

itsyfox 05 Jan 2007, 20:07

Really?

Maybe it's just 'cause my quest was started in b15...

I'll try some things. Importing an unencoded, and such.

If it works I'll continue, but I've started this quest over so many many times in the past, I don't want to do it again just to get it to work with the current beta. :uhoh:

Though technically, even if unencoded doesn't work, I can import a zgp, the maps, strings, and music...

Music's another thing. Since 2.10 I haven't had use of MIDI in either Zquest or Zelda. I've read various fixes on the forum, mainly, change your device in Sounds & Audio Devices. But all I've got is Microsoft Wavetable SW Synth. I also downloaded the old agsetup.exe and played with that, that used to work a long time ago, but no luck.

Oh well, that's probably something to report somewhere else. I know a number of people have reported it before, though, but I don't think I've seen an answer yet that's worked. But if I can get sound working on another computer, I can set up my MIDIs there. I'll just be happy knowing others can hear it and it loops properly. 😉

EDIT!: Looking back through the Open ZC bug forum, I DID find a solution that, funny enough, works! Playing a particular MIDI (in Media Player or whatever you have) resets something, and ZC plays music again! I swear, that thread should be stickied or something for the people with this problem. The person that found it said you have to listen to the song all the way through. I did so, I haven't tried without doing so, so about that I don't know. But the song is here: http://www.vgmusic.com/music/console/nintendo/gba/mirror_boss.mid

I don't know why it works, but it does. That makes me happy.

EDIT, on the raft: Hm, nope. Unencoded quest didn't change anything. Also, the B button's broken, I'd forgotten to mention. :P I tried importing everything separately, but it couldn't import the maps: Incomplete Data. Tried complete, Prefer Original, and Prefer Import. All had the same response.

Sooo I'll be waiting a bit and learning more about scripting, in the mean time. 😊

itsyfox 08 Jan 2007, 17:23

Well, good news! My music's working (as long as I leave media player open after playing that file), I got the raft working again, that bomb script works great, and now I'm almost finished with a raft mini-game script.

The issue my quest was having with the raft was, I forgot I'd tried putting an inherent raft flag on the dock. When I removed that and put a regular flag there, it worked fine. ^_^

I may end up posting the raft script soon. It's working almost perfectly now, except that for some reason a number of rupees I create never leave 0,0 even though I tell them to, and it's in a while(true) { Waitframe(); } loop, and everything! (It's also in a while(NumItems() < number_I_want) loop)

About three to four (it's rather random) of the items stay in place even when I tell them to move. I reference them with a variable, curritem, that I cast in the outermost scope and increment at the end of the NumItems loop IF it's on a combo where a raft flag is placed. Yet some still don't move, and I don't understand. I'll post the code soon. In the mean time, I've just upped the number of items it creates and made the ffc the same water combo that's beneath it and 'draw over'. ^_^
