Changing the ammo system?

<< < (8/10) > >>

Autoquark:
Thanks, yaflhdztioxo. Only three of those being hooks are documented on the wiki.

Does being:wear(item) work on weapons, and does it work for items that aren't in the inventory? I'm trying to implement a grenade weapon that is stored in stacks in the inventory but is equipped one at a time. I've got this:


--- Code: ---register_item "hl_grenade" { --delayed explosion requires more hooks
name = "Hand Grenade",
desc = "Good thing you can throw accurately.",
ascii = "*" ,
color = BROWN,
sprite = SPRITE_ROCKET,
glow = {1,0,0,0.5},
level = 6,
weight = 200,
flags = {IF_NONMODABLE, IF_NOAMMO},
firstmsg = "These could come in handy.",
color_id = "generic",
--type specific
        type     = ITEMTYPE_RANGED,
damage        = "5d5",
    damagetype    = DAMAGE_FIRE,
    group         = "weapon-rocket",
    fire          = 10,
    acc           = 0,
    radius        = 4,
    shots         = 0, --setting to 1 leads to x1 being appended to name, which is seriously confusing here
    ammo_id       = "shell", --not actually used
    ammomax       = 0,
    reload        = 10,
    shotcost      = 0,
    altfire       = ALT_NONE,
    --altfirename   = "double shot",
    altreload     = RELOAD_FULL,
    --altreloadname = "dualreload",
    --sound_id       = "shotgun",
    missile       = "hl_grenade_missile",
psprite   = SPRITE_PLAYER, --the sprite used to represent the player when equipped

OnCreate = function(self)
self:add_property("quantity", 2)
self:add_property("base_name", self.name) --used by test.SetNameFromQuantity
test.SetNameFromQuantity(self)
end,

OnEquipCheck = function(self, equipper)
if self:get_property("quantity") == 1 then return true end

self:set_property("quantity", self:get_property("quantity") - 1)
test.SetNameFromQuantity(self)
local spawned = item.new(items[self.id].nid) --spawn a new grenade item with 1 quantity
spawned:set_property("quantity", 1) --set quantity
test.SetNameFromQuantity(spawned)
if player:wear(spawned) == true then ui.msg("success") else ui.msg("fail") end --equip the new item
return false --don't equip this item
end,
}
--- End code ---

When I attempt to equip a stack of more than 1 grenade, I get the message "success", the size of the stack decreases by 1 but the grenade isn't equipped. Equipping a single grenade works.

Also, it turns out that being.inv:add() does work on monsters. Thanks SPTX for suggesting that - I thought I'd tried it before but evidently not.

EDIT: What sound IDs exist that are appropriate for explosions?

I'll bounce on that asking for a full list of sound IDs.

If I inadvertently end up providing info that's both useful and not on the wiki please put it up.  I would myself but the time... it is not there.

I'll try to do that.

What is it that determines if shottyman applies to a weapon? I assume it's the IF_SHOTGUN flag for shotguns, but is there a new flag for rocket launchers?

SPTX:
It's the IF_SHOTGUN flag indeed, the rocket launcher has it for that matter.
