Bridge Extendor

[pkmnfrk]

Well, I did it my way for three reasons:

1. The code is not much smaller compiled if you combine them, and,
2. I don't want to blindly reset the regular flag if it's triggered by the inherent flag, and,
3. Vice-versa for the inherent flag (which changes automatically, AFAIK).

My code is a little bit more "correct", so to speak, since it handles inherent flags properly, but the two snippets are effectively the same.

Ah, I didn't think of that.

Is there a way to link this script with a freeform combo script, so that the combo that is created can be changed on a screen by screen basis? E.g. on one screen the item creates a bridge, on another it creates land where lava was, etc.

This is great. Simple script with powerful game mechanic applications.

I like the idea of making this script a consumable item that the player needs to collect and use. Just like keys in dungeons. Makes shops more important in the game, and gives you more things to stash away. Don't have to use game counters to keep track of the number of items left. Just use the item flags that potions use to let the player collect more and decrement when used.

Sort of off topic; some other simple scripts you could use to add flavorful utility items would include:
(1) Warp consumables that take the player to the last town visited;
(2) Weapon consumables - scripted weapons on consumable items (like bombs);
(3) Perhaps miniature versions of full items that are consumable, used until the player finds the real item - a rope that acts as a very short hookshot?
(4) Various potions - with short-term effects on the player. Like a power potion that adds a scripted weapon to the player's attack, a speed potion that increases walking speed, defense potion that surrounds player with block-all combos, etc.

I was going to, but then I realized it can be done very easily with secret combos. We don't need scripts to replace already existing features.

Oh, wait, now I know what you mean- so each bridge is different for each screen which the item can be used on.

ffc script BridgeExtender {
    void run(int bridge_combo, int bridge_flag, intSFX) {
        bool found = false;
	while((this->X-8 > Link->X) || (this->X+8 < Link->X) || (this->Y-15 > Link->Y) || (this->Y < Link->Y)) {
            for(int i = 0; i < 176; i++) {
                if(Screen->ComboF[i] == bridge_flag) {
                    Screen->ComboD[i] = bridge_combo;
                    Screen->ComboF[i] = 0;
                    found = true;
               } else if (Screen->ComboI[i] == bridge_flag) {
                    Screen->ComboD[i] = bridge_combo;
                    // I think the inherent flag will change automatically?
                    found = true;
                }
            }
	}
        if (found) { 
            Game->PlaySound(SFX);
            Screen->TriggerSecrets(); //<-I'm pretty sure that's not right. I couldn't find the proper notation in the ZScript documentation.
	}
    }
}

You can't just trigger secrets like that I'm afraid Beefster, you have to put trigger combos under Link's feet and all sorts of such nonsense, it's really rather round-about and not particularily simple.

What's so bad about the whistle, anyway?

[The_Amaster]

Can't you just set it as a standard FFC that triggers off of an item activation?
And, looking into the future and reading Joe's post (oooh, spooky) can it be written using arguments like Beefster's so that the bridge combo can vary from screen to screen?

[Joe123]

Why yes, yes you can.

bool bridge = false;

ffc script BridgeExtender {
    void run(int bridge_combo, int bridge_flag, int sSFX, int fSFX) {
        int i;
        bool found = false;
	while(!bridge){
	Waitframe();
	}
	bridge = false;
        for(i = 0; i < 176; i++) {
            if(Screen->ComboF[i] == bridge_flag) {
                Screen->ComboD[i] = bridge_combo;
                Screen->ComboF[i] = 0;
                found = true;
            } else if (Screen->ComboI[i] == bridge_flag) {
                Screen->ComboD[i] = bridge_combo;
                // I think the inherent flag will change automatically?
                found = true;
            }
        }
        if (found){ Game->PlaySound(sSFX); }else{ Game->PlaySound(fSFX);}
    }
}

item script brigeextender{
	void run();
		bridge = true;
	}
}

EDIT: Damn you edited your post!
Edit it back it was fine! =P

As an aside, a feature we need to bug the devs about is being able to set Screen->D[] in ZQuest. That way, this script would be trivial and generic and stuff:

//Places tiles down when item is used.

const int bridge_flag = 98; //change this to the indicative flag

item script bridgeextender {
    void run() {
        int i;
        bool found;
        found = false;
        for(i = 0; i < 176; i++) {
            if(Screen->ComboF[i] == bridge_flag) {
                Screen->ComboD[i] = Screen->D[0];
                Screen->ComboF[i] = 0;
                found = true;
            } else if (Screen->ComboI[i] == bridge_flag) {
                Screen->ComboD[i] = Screen->D[0];
                // I think the inherent flag will change automatically?
                found = true;
            }
        }
        if (found) Game->PlaySound(SFX_SECRET);
    }
}

If you want to have this functionality, put down an FFC on the screen with this script:

//sets Screen->D[whatever] to something

ffc script setScreenD {
  void run(int d, int v) {
    Screen->D[d] = v;
  } 
}

Set D0 to 0, and D1 to the bridge combo. Then, place it on the bridge screen, and use my item script as above, and you can have any bridge combo you want on any screen.

Edit: I've added these script to my website.
