[Request] Handling Wait/Sleep Within Pulse/EndScene

[Shadowhunter12]

Good Morning Everyone,

I was wondering how people handle this scenario. I am currently using Apoc's FSM to execute logic which is triggered during my Pulse from my EndScene hook. The issue I am trying to work through now is how people handle adding in "Wait" or "Sleep" logic between statements?

For example, say I want to cast a spell and then sleep for 2 seconds and then cast another spell. Since my logic is being executed on the EndScene thread, sleeping the thread isn't the way to go.

If anyone has a moment to share how they dealt with this issue I would greatly appreciate it.

Thanks in advance!

Let's say you want to add a delay between states A and B.

- Add a new state between A and B (let's call it X)
- In state A: Set a counter variable to some value (let's call it fDelay) of ms you want state B to delay by.
- in state X: decrease fDelay by the amount of time elapsed since the last call of endscene.
- If fDelay < 0 transistion to state B, otherwise remain in X.

ccKep,

Thanks for the quick response. I understand what you are saying, however, what if the delay needs to be in a single state? For example, say your state is "InCombat" and part of your logic is:

(Disregard the fact that these are heals)
CastSpell("Rejuvenation")
Wait(2000)
CastSpell("Greater Healing")

Is that even possible to do?

No that's not possible that way.

In general is it a bad idea to call your logic in endscene since it will drop the FPS very very badly. Instead should you execute your logic in another thread and let injected code wait for the next endscene-pulse, execute its code, release the frame and continue as usual.

Ahh ok gotcha, so more of a RunInFrameOnce delegate approach mostly for executing scripts, targeting, and CTM movement?

Makes sense.. Thank you again!

Yes, something like that.

Or simply don't sleep. Train conductors aren't sleeping either inbetween stations (hopefully), although they just keep driving at the same speed without changing the direction. They constantly check for changes in the environment to avoid accidents or w/e. What if you channel a 10 sec cast and get interrupted in second 2? Waiting the remaining 8 seconds would be worse a makeshift.

And if you really want to wait (for whatever reason), just save a timestamp and do nothing until the time elapsed...

Exactly.. A FSM should never ever have a sleep. A little article to read: Thread.Sleep is a sign of a poorly designed program. - Peter Ritchie&#39;s MVP Blog

Using a Pause-State which is able to get passed a condition in which it will constantly check the condition is okay, but not a simple Thread.Sleep since it will slow down everything.



But one thing I don't get: Why the hell does Apoc recomment to call the FSM in endscene? That's a timecritical part and the completly wrong position for a big FSM.

I don't think that AI is hamstringing performance (at least it didn't for me), but you definitely should roll out expensive operations to a different thread).
A single agent AI should never be slow enough to bog down your fps. If it does, you are having serious performance bottlenecks or more likely a bad algorithm for something.

Well depends on what kind of project you're think about: A simple fish-bot which is written within 2 hours or a whole bot with big logics.

All great responses, thanks again I appreciate it!!
