Auto Use Dodge Item When Shocked -Online- [Unnamed]
Online only.
I wanted to see how to improve Vegas Auto Attempt code and this is the outcome. Unlike his code, this code directly hooks the address that calls the shock damage on your console when another slot (not you) fires the shock and is only called once. This is the reason why the code should be completely independent of the NATNEG between clients.
Basically, the code works by delaying the shock damage (a few frames) on your console so that there is enough time to use our dodge item.
In addition to checking if you have a dodge item, this code also checks, unlike Vegas code, if you are already in star or mega state and does NOT fire a dodge item if that is the case. However, also for any moments where you normally can't use an item (i.e. during exit of cannon, spinning from getting hit by an item, etc), the code won't work.
NOTE: This code makes use of memory addresses 0x81670008 thru 0x81670009. Make sure no other codes in your GCT/Cheat-Manager are using those addresses!

## This adress normally calls the "Force Shock damage" on your console if another slot fired a shock. Therefore, it will only get called once, and should not get affected by NATNEG.
## To make the code work, we will overwrite the call and will store a frame counter to memory to let another adress call the event if a certain number is reached. That way, we delay the shock a few frames and can use our item.
## Again I repeat: The adress is ONLY called if another Slot fired the shock, it will not get called if you fire it.

## In Addition, if the frame counter is equal to 4 (two frames earlier than 2), we will use our dodge item (3rd ASM).

RE: Auto Attempt to Use Dodge Item When Shocked -Online- [Unnamed] - Vega - 07-17-2023
Epic!
As an fyi, I initially named my version of the code with the phrase "Attempt to Use" because the code wasn't 100% reliable.
I think your code would suit the shorter name of "Auto Use Dodge Item When Shocked -Online-". Just my opinion ofc. Once again, nice work.
RE: Auto Use Dodge Item When Shocked -Online- [Unnamed] - Unnamed - 07-18-2023
Done. And I also changed the adresses that are used for frame counter and player slot to not have a byte wasted on the EVA.
