CPU Bot (Online) v1.5 [marito_yo]

CPU Bot (Online) v1.5 [marito_yo]

Change: Changed C2 hook to one liner. The C2 hook set it to 1 regardless of case.
Addition: Made "isCpu" bool true. This bool sets some important stuff that CPUs have and it fixes the respawn route issue. Also, it was modified in a way that it will only affect human players so it will not cause online players to have CPU stuff (example: turning).

I wanna race/battle with cpu bot in offline multiplayer, possible?

[_Ro]

This code works offline too. I think marito put (Online) to tell that it works properly online unlike Dea's version.

[Womb]

I know it works in offline, but I would like play against cpu bot.

The gecko code is really cool to use, but when I did the test with a friend to put in 200 CC, I had the impression that the CPU was at 50 CC...

Since the code is using the bot's parameters, I notice that the rubberband mechanic gets a bit confused as to what to do and will simply force a constant rubberband effect.
I use these codes when using the bot codes.
Disable CPU Rubberbanding Effect [b_squo]
Force Set CPU Difficulty [Vega]
Set CPU Soft Speed Limit [B_squo] (You might have to play around with the values on this code to up the speed limit to 200cc's)

Yes, I jimmy'd this up really quick.

Untested, might not work.

#r26 = Slot code is hooked on
#r0 (after OG instruction) is 0 for Human, 1 for CPU, 3 for CPU???
#OG Instruction. The reason im leaving the OG instruction in instead of just directly loading truth table bool into r0 is because for possiblity of this 3 value being loaded. No idea what its for, let's not chance it
lwz r0, 0x0018 (r30)

#Set Truth Table addr

Second ASM Source:

Code:

@Marito_Yo

I don't mean to start any drama, but I am curious. You have yourself as the Code creator, but which part of the Code was authored by you? Which line?

For context, the differences I see between this and Dea's OG version is.. (correct me If I'm wrong)

- First Hook was moved to a slightly different spot in the same responsible Func, which allows a nop of a stb. Thus no more C2 needed, can use a RAM Write (nop). This is a more optimized way to achieve the same effect as the previous version.

- Second Hook was changed to a RAM Write since it was hooked to a Func that returned a bool. Simply editing the bool return value is all that is needed. Code optimization.

- Third Line was added completely from scratch. This is for the other isCPU func as there are two isCPU funcs in the game. Dea's OG version was missing this.

--

So did you add the 3rd line? If not, then the rest would just be code optimizations which doesn't qualify as the Code creator, but does for Code credits. Unless the code optimization added a new feature I'm not recognizing or removed a limitation.

Once again, not trying to start any drama, just want to make sure credits are done correctly.
