A GAPS item. Dun Loireag keeps a Grunty record per town in the save. From it, ccSetChibiGuso places the young Grunty that walks the town and the grown ones at the pens. Kite feeds the young one foods found in the dungeons, and it grows up through four stages into a grown kind. The port's town had none of this: no Grunties, menus 45 and 46 unported, and the dungeons' foods lying there invisible, with menu 43 unported.

The Grunties

• Placement. ccSetChibiGuso places a grown one at DMY_cdog0-2 for each kind the record has. A record at level 4 with a kind free starts over; then the young one (rows 154-157, by level) goes to its route's first dummy. The grown ones are made before the record is cleared and read it as it was, so the port constructs them from a copy of the save taken before the reset.
• The class. ccPGuso (pgbreed.cpp, 0x330 bytes) is ported whole in piney_world::grunty:
  • the walk;
  • sitting and sitting up for the menus;
  • eating, and paramCalc's record, next food and level;
  • the three growing-up acts (the stretch, the cross-fade to the next body, effEvolvePG);
  • growing into a grown kind (adultSetup, evoActAdult: its line, the run-off of a kind the town has, effGrowPG);
  • the placed grown ones' adultMain;
  • the three affect functions;
  • moveCam's fixed camera and the smoke, sounds and voices.
• pgPtr. inuCheckNote acts on pgPtr, the last Grunty made, whichever Grunty's anm passed the note. The port keeps that.
• The world. World lists the Grunties after the dogs, as ccEntryEventMng makes them, under the row each was made from (its base changes as it grows). Affects reach the class at once. The camera writes and Kite's placing are carried out after the list.
• The effects. piney-effect's new pg holds effEvolvePG (the -7 controller: generators 126 and 127 at count 12, 128 at 30, following the Grunty half its height up, from posT) and effGrowPG (generator 129).
• Drawing. The main anm is drawn through ccChar::Draw's shadow.
• The Grunty files. Their first CMP_trall is an animation's, whose nodes are ExtObj copies of the model's objects. Body::of now follows a node's ExtObj copy to its target (as ccMatchIndex does). Without that the Grunty drew nothing. Bodies whose nodes are their own objects are unchanged: the world, shadow, foe and town harnesses still match.

Menus 45 and 46

• The menus. OtonainuMenu (45), InuMenu (46) and InuMenuDisp are ported in menus/inu.rs: the fade to the fixed camera, the STATUS window, Talk, and Give Food into BreedingMenu.
• The Grunty's line. The affect functions change the Grunty's msgNum at once, and the game's menus read it straight after. The port's menus see the world's Grunty as the frame began, so after_affect makes the same change to their copy.
• The runtime. piney-game hands the menus the Grunty (World::grunty) and carries out their requests: Feed (affect 19), growthNum, foodMode and chatFlag. It also turns the Grunties' events into sounds, effects, voices (a grown kind's through ccCheckVoiceGrp) and chat lines.

The foods and menu 43

• The food. Gimmick rows 22-37 (FOOD_00-0F, key items 26-41; 22 the Golden Egg) are ccGimFood. SetItemBox puts them in the dungeons' box slots. The port made them as inert gimmicks that drew nothing. gimmick::food_new and food_main port it:
  • it wobbles and rolls, turns to Kite and calls out within 1000 (ccVoicePgFood);
  • FoodMenu's affect 11 takes it (sound 179 on note 70), then it bursts (effOpenBox, sound 77, the bounce and fade);
  • it is drawn at SetMatrix_PosRotZYXScale. Its act and count are ccGimmick's own actNum and actCnt.
• The menu. FoodMenu (43) is VirusMenu's shape. The item is 0xf0000 | (base->id + 4), and foodCount (+0x7446) goes up.
• The voice. ccVoicePgFood sets its own request from voiceFoodTbl(E) and FOOD.BIN. The tables (generated) carry it as EvVoice::food. The runtime asks for it as event -100, which Audio::voice routes to Driver::food_voice_request. The driver's voice_request still plays nothing for -100, as ccVoiceRequest does.
• The riding Grunty. The flute that calls one (key item 49) is given by BreedingMenu when a new grown kind appears. So Infection reaches the ride. It is not ported here: it is the next task.

Checks

• tools/test_grunty_rs.py. Runs the game's ccSetChibiGuso, ccPGuso's constructor and main in eemu over town02, beside grunty_probe, in 15 scenarios: the walk, talk, eating, each growing up (0 to 1, 1 to 2, 2 to 3, 1 to 3), a new kind, a kind the town has, one far from a kind, the chat lines, a fresh one fed to a grown kind over five meals, and grown rows 145-147. It compares every member, the anms, notes and draws, and the events each frame. The events now carry the height the effects read. All match.
• tools/test_fieldui_talk_rs.py. GruntyPages covers 45 and 46. All 33 tests match.
• tools/test_fieldui_rs.py. test_food opens 43 on bases 22, 29 and 37. All 51 tests match.
• tools/test_battle_spawn_rs.py. The harness now runs the constructors of ccGimFood and ccGimSymbol natively (sizes 0x240, 0x710), and reads their members. item_box compares the foods and symbols SetItemBox makes, and gim_frame compares food frames (main, actRolling) near and far, taken and not.
  • Before this, the harness stubbed the symbol's constructor while the probe ran the port's (worklog 0149). So dungeon_mc (the lakes' row 18) and item_box (kind 4) failed.
  • All six tests now pass, and the symbol's constructor is checked against the game for the first time.
• tools/test_effect_misc_rs.py. GruntyAgainstGame runs effEvolvePG and effGrowPG on moving characters: 30 cases, 141 generators, every slot each frame. It first caught posT.
• Sessions.
  • the_grunty_eats_and_grows: the young Grunty walks. InuMenu opens on it under the fixed camera and it sits. Three foods make it Little Grunty (row 155, size 6, its voice). Talk gives its line. Leaving brings the field camera and its walk back.
  • the_grown_grunty_talks: row 145 from a record with kind 0, which starts over; OtonainuMenu opens, Talk and back.
  • a_grunty_food_is_picked_up: a Golden Egg in area 26's dungeon calls out, FoodMenu takes it, it bursts, and key item 26 and foodCount go up.
• Shots. grunty_shots saves the walk, the menu, the change and the grown Little Grunty. grunty_food_shots saves three foods lying there and one taken.
• The rest. The workspace's tests pass, as do the world, town02, shadow, foe, sound, effect and field-UI harnesses.
