Worklog 0149 ported the story dungeons' symbols (gimmick row 17, symMain) and left row 18, the lakes' SYMBOL_OBJ, with its constructor only. In a lake dungeon (types 8 and 9) DUNGEON::SetMagicCircle puts one at every rolled OBJ_0ps* slot of the rooms. They stood there dark and did nothing, and SymbolMenu (36) on one never cast.

objMain (gcmn 0x0045aed0)

ccGimSymbol::main (0x0045aa40) returns objMain's result for row 18. Unlike row 17 there is no body, no fires and no initFlag handling.

• Every frame. The light goes to 1 + ccRandF(0.2) at its place, 60 above the symbol, taken to the player's frame (ccTransPosFW2LW), and into the group.
• act 0. The count goes up. Affect 11 (SymbolMenu's close) starts act 1.
• act 1, frame 0. Off the command lists (deleteCmnd(1)), sound 35 at the symbol, effUseSymbol at the light, and ccItemSkillRequest(this, affectPerson, trapNum, 0). Unlike symMain, param[2] is left alone.
• act 1, frame 30. Act 2 with the light out.
• act 2. It returns 1, so the entry control deletes it and ccDestGimSymbol takes the light away.
• Smoke. On an even count, one puff: effSmoke(pos, v, 1.0, 8, 204, 512, 32). It starts 10 out from the light along a heading of three ccRand() turns (X, Y, Z) and flies out along it, 2.5 up. That is invokeEff's heading with 2.5 in place of 2.0.

The port

• gimmick::obj_main holds the above.
• invoke_eff and it share scatter for the heading.
• New Out::SymbolSmoke { pos, v }, which piney-game's fx sends to effSmoke with those arguments.

Checks

a_lake_symbol_glows_and_puffs (session, in shrine.rs, whose walker it uses) warps from Mac Anu with words 1, 136 (Solitary: field type 4, no field, straight into a lake) and 150. A scan of the words found lakes with and without symbols; this one rolls a symbol in room 1. Kite walks there, and the symbol runs: act 0, its count past 20, its light in the group. The session tests' disc, start, hold, wait and playing became pub(super) for it.
