Item Timer [JoshuaMK]
This code will keep track (via Milliseconds in timer) of how long you have left before your timed item (Mega Mushroom, Golden Mushroom, or Star) runs out. Whenever you are not using any of these items, the timer will function normally.
Works in all modes, offline and online

RE: Item Timer [JoshuaMK] - Vega - 03-18-2020
Does the timer still work if you lose your Timed Item under any condition? (Can't test code atm)
RE: Item Timer [JoshuaMK] - JoshuaMK - 03-18-2020
Yes it does. I made sure to die and get hit a few times and it was working. The problem with your old code is that you hook addresses and stuff for letting the timer act as normal wouldn't be called when a player directly lost their item.
This code however, directly calls the pointer chain for each item accordingly so that the timer value for each timed item is always accessible at any point in time. In this case, being the player's timer hook itself.
RE: Item Timer [JoshuaMK] - Vega - 03-18-2020
Very nice. Moved all my timer codes to Incomplete/Outdated.
RE: Item Timer [JoshuaMK] - Unnamed - 03-19-2020
Great code, Joshua!
RE: Item Timer [JoshuaMK] - Vega - 03-26-2020
Btw I noticed you still have the 'untested' next to online
RE: Item Timer [JoshuaMK] - JoshuaMK - 03-26-2020
Has it been tested?
RE: Item Timer [JoshuaMK] - Vega - 03-26-2020
Yes it has. My bad, I forgot to tell you some days ago.
RE: Item Timer [JoshuaMK] - JoshuaMK - 03-26-2020
Well I fixed it
RE: Item Timer [JoshuaMK] - Unnamed - 06-23-2020
After few testing, I can say that it don't work on Wiimmfi with patched main.dol.
Sad, then I try an Alternative.
EDIT: It looks like the code is not quite correct. It loads the pointer, but always only the one for the player in the first item slot (Player 0). I have seen with the "Mega lasts forever" code from mdmwii that it stores this value and adds between lwz r11, 0x20 (r11) and lwz r11, 0x0 (r11) to the address. Then the mega and star timer worked fine for me. Maybe you can test it yourself and judge what I have said. Here is the PAL code, I have marked the Changes in red:

The First ASM stores the local player item slot to the Memory Location 80000FC8 and in the Timer ASM, this Value is loaded and add to the Adress to compute the correct pointer.
I only don't know how to use it for the Golden Timer, that should then somehow work similarly.
