[Other✓] Displaying time in the start menu

[Gengalorian]

Hello, I would like to display the current time while you are in the start menu. So far I have I managed to display the time. However, it is stuck on the time you open the menu. A second problem is when speeding the game up, it no longer displays the correct time, as more game time has passed compared to regular time. Does someone know how to solve this?

This is what I have done so far:

Spoiler:

Basicly everything happens in src/start_menu.c
at the top of the file i added

#include "rtc.h"

then, in the EWRAM section, underneath sBattlePyramidFloorWindowId I added:

EWRAM_DATA static u8 sStartMenuTimeWindowId = 0;

next, under sPyramidFloorWindowTemplate_1:

static const struct WindowTemplate sStartMenuTimeWindowTemplate = {0, 1, 1, 0xA, 2, 0xF, 8};

next for the actual code for displaying the time box, underneath static void ShowPyramidFloorWindow(void):

static void ShowTimeWindow(void)
{
    sStartMenuTimeWindowId = AddWindow(&sStartMenuTimeWindowTemplate);
    PutWindowTilemap(sStartMenuTimeWindowId);
    DrawStdWindowFrame(sStartMenuTimeWindowId, FALSE);
    ConvertIntToDecimalStringN(gStringVar1, gLocalTime.hours, STR_CONV_MODE_LEADING_ZEROS, 2);
    ConvertIntToDecimalStringN(gStringVar2, gLocalTime.minutes, STR_CONV_MODE_LEADING_ZEROS, 2);
    ConvertIntToDecimalStringN(gStringVar3, gLocalTime.seconds, STR_CONV_MODE_LEADING_ZEROS, 2);
	StringExpandPlaceholders(gStringVar4, gText_StartMenuTime);
    AddTextPrinterParameterized(sStartMenuTimeWindowId, FONT_NORMAL, gStringVar4, 0, 1, TEXT_SKIP_DRAW, NULL);
    CopyWindowToVram(sStartMenuTimeWindowId, COPYWIN_GFX);
}

then in the function RemoveExtraStartMenuWindows, I added:

	if(!GetSafariZoneFlag() && !InBattlePyramid())
	{
		ClearStdWindowAndFrameToTransparent(sStartMenuTimeWindowId, FALSE);
        RemoveWindow(sStartMenuTimeWindowId);
	}

and finally in InitStartMenuStep in case 3:

		if (!GetSafariZoneFlag() && !InBattlePyramid())
			ShowTimeWindow();

I also added strings in src/strings.c and include/strings.h
in src.strings.c I replaced an unused string with const u8 gText_StartMenuTime[] = _(" {STR_VAR_1}:{STR_VAR_2}:{STR_VAR_3}");
and in include/strings.h I added extern const u8 gText_StartMenuTime[];

Hopefully someone could help me with this, thanks in advance!

However, it is stuck on the time you open the menu.

Instead of only drawing the time when the menu opens, you could probably use a task to repeatedly draw the time, so that it changes as time advances.

A second problem is when speeding the game up, it no longer displays the correct time, as more game time has passed compared to regular time. Does someone know how to solve this?

How speed up interacts with rtc depends on the emulator and its settings. You can't really change that by editing the ROM.

Thanks for the quick response!
I have looked into how tasks work but couldn't really figure it out but hadn't read the guide you linked, so I'll look at it again!

So it is not possible to load the system time instead of the internal game clock?
Thanks again!

While you can't modify how an emulatior's Fast Forward feature interacts with the game, you can work around the core problem.
If you synchronize the game's play time with the real time that's coming from the RTC, the game's Play Time will be naturally unaffected by speeding up functions of any kind.

Thanks for this!

I still can't manage to figure out how to make a task that handles the redrawing of the time. I've also looked at the cfru files and that contains a ForceClockUpdate function in the HandleInputs section. but looking further into this leads me nowhere. I hope someone can help/show me how to actually make the task and where I should create it. Thanks in advance

Personally, I implemented the feature in my personal branch through one of Citrus Bolt's public commits, and it works nicely.

It works perfectly! Thank you very much!
