SRB2Kart Saturn: Custom lua features

mobj.localskin and player.localskin fields

Allow reading and assigning localskins.

mobj.rollsum field

Not netsafe. Returns total sprite rotation value, taking sliptideroll and sloperoll cvars value into account. Mainly for use in visual-only addons like secondcolor.

player.sliproll field

Not netsafe. Returns player's current sliptide roll angle, taking sliptideroll cvar value into account.

hud.setVoteBackground(name)

Changes vote background texture prefix (game looks for PREFIX + "W" or "C" (depends on resolution) + FRAME_NUMBER).

hud.add(fn, "vote") and hud.add(fn, "intermission")

Hud hooks for vote screen and intermission screen. They only get drawer (v) as argument. To check if those hooks are available, check if globals FEATURE_VOTEHUD and FEATURE_INTERMISSIONHUD exist.

x, y = hud.getOffsets(item)

Returns the values of the given HUD item's xoffset/yoffset cvars. Available for any HUD item with offset cvars.

x, y, flags = v.getDrawInfo(item)

Returns the X, Y and flags where the given HUD item will be drawn for the current displayplayer. Available for item, gametypeinfo and minimap.

patch, colormap = v.getColorHudPatch(item)

Returns the patch and colormap to use for the given HUD item. Colorization is based on the user's settings. Available for item and itemmul. Extra arguments for some items:

item

small: true for small item box, false for big item box.
dark: true to darken item box. Depends on darkitembox.

itemmul

small: true for small sticker, false for big sticker.

hudcolor = v.getHudColor()

Returns the displayplayer's HUD color.

colorize = v.useColorHud()

Returns true if colorization is enabled, false otherwise.

mobj.spritexscale, mobj.spriteyscale, mobj.spritexoffset, mobj.spriteyoffset, mobj.rollangle, mobj.sloperoll, mobj.rollmodel fields

Same fields as in SRB2 2.2

S_StopSoundByNum

Allows stopping specific sound globally. Because this function starts with S_, like state, checking if it exists is a bit more complicated:

if rawget(_G, "S_StopSoundByNum") ~= nil then
    ... -- Can use it
end
