Halloween Witches, V1.5.2:

Adds a squad of 3 witches near the witchpoint beacon on October the 31st
Thanks to Eric & CommonSenseOTB for their fantastic scripting and Smivs for bugfixing the non appearing pumpkins issue
Original post:
Does anyone know if there's an OXP ship somewhere that only attacks using missiles? I need something like this for a halloween witch oxp, i don't want to give her lasers, i'd rather she just attacked using an unlimited supply of custom missiles shaped like pumpkins
I've got all the objects appearing in game but i'm missing something - she just won't fire any missiles - even if i prod her a few times with a pulse laser 
WIP version of the oxp here:

Note: this oxp has a script that spawns two of the witches outside the station whenever you launch

Incoming!
Missiles need an equipment key in their 'roles'.
In the witches shipdata, make the
Code: Select all
missile_role = "EQ_griff_pumpkin_missile";
and the pumpkins' shipdata also needs the 'EQ_' , so
Code: Select all
roles = "EQ_griff_pumpkin_missile";

The AI command fireMissile (with a suitable target set first), or indeed the equivalent function (with brackets) in JS, is your friend (or black cat) here...

Back in 1984, i wonder if Bell and Braben ever foresaw something like this in the future of Elite...
Griff, if you use your flickery engine power script, could you paint up the pumpkins to make it looke like they had a candle inside like a jack o'lantern? might look a bit Horsemanish if you see some of them swooping towards you.
oooh - be even better if they explode into pulp when you ECM them
edit
Black cats - sounds familiar. haha, geddit?
anyways - how come you need a script thing to do this? if you design a ship w/ no main gun how come it won't use the weapons it does have, instead? just curious...

Thanks Guys! I've got the pumpkins working now - i think i'll give her a small, weak plasma turret as a main weapon, and she can fire off her pumpkins whenever the mood takes her, plasma bolts look a bit like magic spells, well sort of...
@K_W - she did use her missiles, but seemingly only after you shot at her a bit - i've got the flickery engine effect added in as a glow map on the pumpkin face, i think i'll have a bit of an experiment with wobbling the scale using a vertex shader, see if i can get them squash & stretching like the bouncing pumpkin character in 'Cauldron 2' on the C64.
edit: actually, K_W that's a great idea, maybe if you ECM them they can burst into 4 smaller faster mini-pumpkins
actually, does anyone know if it's possible to modify the players hud on the fly, so that if they get hit by a pumpkin their screen gets obscured by a splat of pumpkin goo?

As thargoids says you must explicit fire the missiles in your script, or oolite will decide for you. However just using the AI command
fireMissile might give unwanted results for you as oolite will use random missiles in 10% of the cases.
To get full controll define in shipdata:
that way the ship will be initialized without any missiles. Than in the AI fire a missile with:
Than in the ship script of your ship (you have to add one) add the lines:
Code: Select all
this.$fireMissile = function ()
{
this.ship.awardEquipment("EQ_griff_pumpkin_missile");
this.ship.fireMissile();
}
That will guarantee that only this missile is loaded and than immediately fired. So your bay is empty again and oolites internal code will never be able to fire one unexpected. This code will supply an unlimited amount of missiles as you requested. When you want a limit, just add a counter in above function like:
Code: Select all
this.missiles = 6;
this.$fireMissile = function ()
{
if (this.missiles > 0)
{
this.ship.awardEquipment("EQ_griff_pumpkin_missile");
this.ship.fireMissile();
this.missiles--;
}
}

Very cool Griff!
Have you got a picture of the pumpkin goo as it looks like smeared on the viewscreen? I could probably make a script that checks which missile hit you, stores which hud you had, switches to a hud with just the goo on it, and using a timer replaces back the previous hud. Would be fun to try and get it to work over the next couple of days. Maybe find a splat sound for it too!

Give her a wand and have the plasma spurt from the tip of the wand....
BTW, just wanted to say - wonderful Griff, really wonderful (or given the celebration more accurately - Terrific)

Hehehe - cool OXP and nice model/texture work, Griff!

Two possibly ways, I'd think. Either the way CSOTB has suggested or via shader (like the hyperjump in BGS or the overlays in Vector). CSOTBs way will work for all users, so it's probably the better option here.

Griff, I've got something that might work. When you have a version for test where the missiles work the way you want them to, then I will attach a script to the pumpkin missile and have a test. You will have to provide a png of the pumpkin goo however for me to install as my test will simply use a test picture only.
