Daily Random Egg

randomegg randomegg2 randomegg3

Ever wanted to get a random Pokemon egg without knowing what you'll hatch?

This script adds an NPC "working for the Daycare Center" that will give you a random egg from a selection once per day. It also gives two specific eggs for your 10th and 20th.

The selection on mons can be added to or removed, as many as you want, just add SPECIES_* to the list.

Steps:

in include/constants/flags.h, rename any unused daily flag to:

#define FLAG_DAILY_RANDOM_EGG_NPC                   (DAILY_FLAGS_START + 0x0)  // Unused Flag

(Any unused daily-safe flag is fine to use. It must be a daily flag to have it automatically cleared each day)

in include/constants/vars.h, rename any unused var to:

#define VAR_DAILY_RANDOM_EGG_NPC                                0x409B // Unused Var

(any unused VAR is fine)

in src/field_specials.c, add these 3 lines to the top in the #includes section

#include "daycare.h"
#include "constants/species.h"
#include "constants/region_map_sections.h"

Add this section to the end of the file


void GiveRandomEgg(void)
{
    static const u16 randomEggSpeciesList[] = {
       SPECIES_GASTLY,
       SPECIES_SURSKIT,
       SPECIES_LICKITUNG,
       SPECIES_POLIWAG,
       SPECIES_HOPPIP,
       SPECIES_RATTATA,
       SPECIES_DROWZEE,		
       SPECIES_TYROGUE

    };

    struct Pokemon mon;
    u32 eggCycles;
    u16 species = randomEggSpeciesList[Random() % ARRAY_COUNT(randomEggSpeciesList)];
	
	// change MAPSEC_ROUTE_117 to any map you wish
    CreateEgg(&mon, species, MAPSEC_ROUTE_117);

    // Return value ignored (should only ever go to party)
    GiveMonToPlayer(&mon);
}

in data/specials.inc, add this line to the end of the file

	def_special GiveRandomEgg

In your chosen map script or where you insert custom scripts (I chose outside the Daycare Center on Rt 117), add the below. Then in your map, add an NPC object and give it Route117_EventScript_DailyEgg_Start
