    Fire Rod

    I'm going to attempt to create a proper fire rod item, before I do I was wondering if someone already did this. Would save me the trouble.
    Lost my wings and grew 8 tentacles... I've seen enough Hentai to know where this is going....

    Ok so here is the data from my first attempt.

    Code:
    const int BOLT_NOUSE = 64;//1 second pause
    const int FLIP_NO = 0;//no flipping
    const int FLIP_H = 1;//Flip Horrizontal
    const int FLIP_V = 2;//Flip Vertical
    const int FLIP_B = 3;//Rotate 180 degrees
    const int BOLTCSET_NF = 6;
    const int BOLTCSET_F = 0;
    
    item script BoltSpell //basic use a wand and cast a spell stuff
    {
    	void run(int power, int arrowSprite, int speed, int wandSprite)
    	{
    		int startX;
    		int startY;
    		lweapon l;
    		lweapon bolt;
    		startX = Link->X+8;
    		startY = Link->Y+4;
    		Link->Action = LA_ATTACKING;
    		l = NextToLink(LW_WAND,8);
    		l->Tile = wandSprite;
    		if (Link->Dir == DIR_UP)
    		{
    			l->Flip = FLIP_NO;
    		}
    		if (Link->Dir == DIR_DOWN)
    		{
    			l->Flip = FLIP_V;
    		}
    		if (Link->Dir == DIR_RIGHT)
    		{
    			l->Tile++;
    			l->Flip = FLIP_NO;
    		}
    		if (Link->Dir == DIR_LEFT)
    		{
    			l->Tile++;
    			l->Flip = FLIP_H;
    		}
    		bolt = NextToLink(LW_ARROW, 8);
    		bolt->UseSprite(arrowSprite);
    		if (Link->Dir == DIR_UP)
    		{
    			bolt->Flip = FLIP_NO;
    		}
    		if (Link->Dir == DIR_DOWN)
    		{
    			bolt->Flip = FLIP_V;
    		}
    		if (Link->Dir == DIR_RIGHT)
    		{
    			bolt->Tile++;
    			bolt->Flip = FLIP_NO;
    		}
    		if (Link->Dir == DIR_LEFT)
    		{
    			bolt->Tile++;
    			bolt->Flip = FLIP_H;
    		}
    		bolt->Damage = power;
    		bolt->Step = speed;
    		Link->ItemJinx = BOLT_NOUSE;
    	}
    }
    Problem 1: The wand is being rendered too high vertically on Link's spirte. I compared it to the sword location and it appears to be a good 6 pixels or so higher (about nose level instead of hand level). I tried reducing the Y position to +4 from +8 (line 18), but that had no visual effect at all on the placement of the sprite. How do I fix this so it looks like a normal use of the wand?

    Problem 2: Not sure if this is possible but can the damage type of the attack be changed to fire? This is supposed to be a fire rod after all. Also would like to know how to get the bolt to render an actual flame at the impact point.

    Next Steps: Currently contemplating using an advanced dark room script to make LttP style braziers. I thought it would be possible to allow the Fire Rod to light them either by using an invulnerable enemy that is invisible set on the brazier. However the thought also occurred that this would probably work better as an FFC script but I am rubbish at those currently.

    Currently for the "Next Steps" portion I am considering using the "Subpar Dark Room Script" found on Pure, unless someone could suggest a better one?

    I'm surprised that worked at all. Unless you're using 2.50.3. (In which case, I want to start working with it ASAP.)

    Normally, you can't make LW_WAND via script. The best functions for placing an item, lweapon, etc. near Link are InFrontX and InFrontY. (They're in stdfunctions)

    That'd look something like this...
    Code:
    lweapon wand;
    wand->X=Link->X+InFrontX(Link->Dir,2);
    wand->Y= Link->Y+InFrontY(Link->Dir,2);
    The placement of the sprite may be due to the sprite itself.

    As for enemy defenses, that's another matter entirely. It's not really possible without some heavy duty engine-level scripting to make it where a LWeapon is one type but does damage to an enemy based on a different type of defense.

    I have a custom script header in the works which does a lot of this sort of thing automatically if you want to try and make sense of it.
    It can be found here.

    It has a custom fire rod included, though it doesn't always make fire as it should (and doesn't do that enemy defense thing).

    In general, you want LW_SCRIPT for this, or LW_BEAM, or even LW_REFMAGIC.

    There was a recent request on Pure for this sort of thing, but I frankly do not want to do it until 2.54 is out, and I can make it both cleaner, and easier.

    Sounds like some exciting changes are coming in 2.54 that will make everyone's lives easier.

    Code as it is doesn't compile, copied from the link you left. Not sure if its a version thing or a syntax thing. Made an attempt to fix it and ran into more errors. Seems to be syntax.
    Lost my wings and grew 8 tentacles... I've seen enough Hentai to know where this is going....

    IDK if you compiled the latest. I expect errors as this is pretty long, and I rewrote it from scratch today, based on the formula that I used in the past. You will have a number of errors if you are not using 2.53 though, as it relies on std.zh stuff such as FLIP_ and ROT_ . It'll give you missing identifiers for those, and then syntactical stuff, might follow.

    For the most part, I wanted to outline it, and push it to the Z3 template package. I can fix it, or update it, later, but you can always have a look at how I did things and try to implement them on your own, if you wish. I have been putting this off because I wanted to make it for the Z3 package, which will use 2.54 or above for quite a lot. Nothing in it is 2.54-specific though, unless the array usage is a problem. I'll load it and see what happens.

    Here is a version free of compiler errors:

    }
    It should be obvious, but, this does not mean that it works as-is. I fixed all of the actual syntactical issues, but I have not tested it. Any major issues at this stage, would most likely be from inappropriate pointers, calling stuff in loops using the wrong identifier, or the wrong array index; and similar. Then again, it might work. You never know.

    You can view the diffs on GitHub if you want to see what I changed at each stage.

    Well I am still trying to learn. Sadly my knowledge is woefully lacking. I'll give it a go tonight and see if I can fix any errors that pop up. If I'm successful, I'll repost the results.

    Think I'm using 3.50.? Bit I'm pretty sure I downloaded 3.53.? . Currently in very early stages of my current project so I've been running code on my TestBed, then adding to the actual quest once I have confirmed it's working as intended.

    I think that you mean 2.53.

    Latest 2.53 Beta as of this post.

    Let me know if it works. It's pretty complex, and will likely need me to do debugging.

    @Lelouche Vi Britannia : I also wanted to say that you are doing fine, picking up this stuff. You are quicky learning style elements, how to keepthings clean, and the syntax. Well done.
