Glass types

The breakable-glass types: CfgSetGlassProperties(type, windowLink, alarm, sprite, brokenSprite) configures each in config_preload2.lua, and a level script places panes with SpawnBreakableGlass(type, corner, cornerU, cornerV, uv0, uv1, 0, triangle1, triangle2) (World objects: glass).

What is complete

All 19 types are listed with every argument. Any hit breaks a pane (no hitpoints); what breaking does is on World objects: a pane's life. The sprite words' low halves are rectangles of part_page1, the sheet of sprite batch 0 that every pane but type 14 draws from; their high halves are ignored (World objects: drawing a pane).

19 entries. Data: research/references/glass-types.yaml.

14	yes	no	0x00020000	0x00010015	Stained glass: draws with a one-sprite batch of its own over sheet-table record 2, rectangle 0, instead of the type's sprite words, and shatters as sub_stained_glass.
15	no	no	0x00010014	0x00010015	Invisible: colour 0, so drawn fully transparent; still blocks until broken.

17	no	no	0x00010015	0x00010015	Placed already broken: its triangles are off, but it draws its sprite (the broken rectangle) and has a body within 50 m like a whole pane.
18	yes	no	0x00010015	0x00010015	Placed already broken: its triangles are off and its path polygon's flag 0x08 is set, but it draws its sprite (the broken rectangle) and has a body within 50 m like a whole pane.

Fields

Field	Type	Hand-written	Meaning
id	int		Glass type: SpawnBreakableGlass's first argument and CfgSetGlassProperties'.
window_link	bool		Second argument (+0x14): the pane sits on a navigation jump link, closed while it is whole and opened when it breaks (inferred).
alarm	bool		Third argument (+0x18): breaking the pane reports a break-in.
sprite	hex		Fourth argument (+0x1c): the whole pane's sprite word; its low 16 bits are the rectangle drawn.
broken_sprite	hex		Fifth argument (+0x20): the sprite word left after the pane breaks (0 draws nothing).
behaviour	str	yes	What the code does differently for this type.
panes	int		SpawnBreakableGlass calls that pass the type.
scripts	list		The scripts that place panes of it (at most six).
source	str	yes	Where the entry comes from: a script and binding, an address, a chunk.
evidence	str	yes	How we know: confirmed-code, confirmed-runtime, inferred or speculative (evidence levels).
notes	str	yes	Our own short notes.
