27 Blizzard Constants:
28 - NUM_MULTI_CAST_BUTTONS_PER_PAGE = 4
29 - NUM_MULTI_CAST_PAGES = 3
30 - TOTEM_PRIORITIES = { } -- sets the order of the totems
31 - TOTEM_MULTI_CAST_SUMMON_SPELLS = { } -- list of summon spellIDs
32 - TOTEM_MULTI_CAST_RECALL_SPELLS = { } -- list of recall spellIDs
33
34 Blizzard Events:
35 - UPDATE_MULTI_CAST_ACTIONBAR
36
37 Blizzard APIs:
38 - GetMultiCastBarOffset() : returns 6
39
40 - SetMultiCastSpell(actionID, spellID) (protected) OR
41 SetAttribute("type","multispell")
42 SetAttribute("action",actionID)
43 SetAttribute("spell",spellID)
44
45 note: multicast actionID page is NUM_ACTIONBAR_PAGES + GetMultiCastBarOffset(),
46 so that's action ID 132-144.
47
48 - spell1, spell2, spell3, ... = GetMultiCastTotemSpells(slot)
49 returns spellIDs for all totems that fit that slot.
50 Note this is available in the secure environment, but because IsSpellKnown() is not,
51 it makes it pretty much useless.
52
53 Blizzard textures:
54 All the textures for the multicast bar (arrows, empty-slot icons, etc) are part of a single
55 texture: each texture uses SetTexCoord() to display only a slice of the textures. I suppose
56 this is to slightly optimize texture load performance, but it makes the UI code more clumsy.
57
58 Each totem button and arrow has a colored border indicating its elemental type.
59 TODO: update code to use these pretty per-slot icons, or start setting a border.
60
61 Design Notes:
62 - Only the header has a secure context. All other frames execute in its context.
63
64 - Each button is either type "spell" (summon/recall) or type "action" (totem action IDs are
65 GetBonusBarOffset()=6, 132-144) with 3 pages of 4 buttons. The paging is controlled by
66 the summon flyout, which is also paged with the summon spells (the recall button is not paged)
67
68 - A spell list is updated in the secure context at setup time (TODO: redo setup when learning new
69 spells) with the list of spells known for each slot.
70
71 - Each button (except recall) has an arrow button which appears on mouseover and when clicked
72 opens the flyout via a wrapped OnClick handler. When the flyout is open, the arrow does not
73 appear.
74 TODO: add an alt-button ("SHOWMULTICASTFLYOUT") statemachine to the bar to listen for alt key
75 presses and open/close the bar. Tapping the alt key toggles the flyout.
76
77 - A single flyout with N+1 (1 slot is to select no totem for the set) flyout-buttons is a child
78 of the bar. Each time the flyout panel is opened, the individual buttons grab their corresponding
79 spell/type from the list, according to the slot which opened the flyout. Each button either sets
80 the current page (summon) or sets a multispell to an actionID via type="multispell". None of them
81 actually cast any spells (though, I suppose we could modify this so that e.g. configurable
82 right-click casts the spell). The flyout also has a close button which closes the flyout: the
83 flyout-open code positions the close button anchored to the last button in the flyout (which
84 changes dynamically because each slot has a different number of items in the list).
85
86 - Multicast sets are not stances, there's no need (or ability) to handle swapping sets if one of
87 the summon spells is cast from elsewhere. Additionally, in the default UI Call of the Elements
88 always appears as the active summon when the UI is loaded, which is bad design that could be improved
89 upon. TODO: Store state in a config variable and restore it at load time.
