Halo 2: Tickrate AI Balance Fix

Descripción
MCC's Tickrate broke the AI, I fixed it

There is a notorious bug with Halo 2's AI in the MCC release, they act at double the speed they should, oftentimes causing instant death. This is due to AI running every tick. In MCC, that tickrate has been increased to 60. The AI update at 30 hz, the game updates at 60 hz. Combine the two and you get AI that update twice per second. This mod multiplies their timers to ensure that they can't update more than once per second. For some reason, shield recharge speeds are also affected by this bug so they've been fixed too.

What this fixes:
  • Instant deaths due to mass damage.
  • Jackal Snipers can actually be reacted to. They also can't fire twice at a time.
  • Shield recharge speed no longer outpaces weapon damage.
  • AI computation has the correct timings.
  • Behavior is 1 to 1 to it's Original Xbox version.

What this does not fix:
  • Tickrate issues not related to gameplay.
  • Legendary being extremely unfair. It's just playable. Play Heroic.

Further explanation.

0.566 is the limit because of two reasons.

0.5 ensures that 30 hz is skipped every second. It skips half the first update then half the second update. This puts the total delay at 0 seconds.

If you use 1, it would normally skip one full update then fire, however now it is skipping one, firing, then skipping another and firing again, putting the delay at 0.5 seconds.

If you use 2, it skips both updates then fires, putting the delay at 1 second.

Etc, etc.

0.066 ensures another 33 ms of time is skipped per update, in case any frame dependent actions are being taken.

They fixed the weapon bugs but not the AI bugs. I fixed the AI bugs.

I thought they fixed this bug in the past, or is it they only fixed tickrates in Multiplayer?

The mod tools don't support it, so idk, has anybody else gotten Halo 2 Anniversary mods?

Can you eventually get this working with anniversary graphics ?

The tickrate causes double updates, which you have to fix. There's then the fact that a lot of timers update per frame, so they need a delay added to not outpace the engine. The complicated part when it comes to the new tickrate is that 0.5 = 0.

So, for example if I want to take a timer with a .1 delay and fix it, then I have to use the following formula:

0.1 * 2 + 0.566 = 0.766.

But the really fucking annoying part is that some things have parent timers, so you have to figure out what the parent timer is. Changes to any timer underneath the parent work normally, the parent is the one that updates per tick.

For AI behaviors, it's the perception timers.

For AI attacks, they use the difficulty scales.

It is very, very complicated.

I don't think most people actually have the knowledge to implement this fix correctly is why it hasn't existed thus far.

This is amazing and should be integrated into every single mod on here. MASSIVE oversight that this bug is present and I'm surprised I'd never heard of it before.

New update fixing the AI computation speeds, so now both their combat behaviors and regular behaviors are fully restored.

I can do everything but Reach due to compatibility issues.

The jackal leg thing is just because the jackal's legs don't have collision. That's not a bug, it's actually just the case for every character before Reach.
