Inteligent chasing

[Apeirogon]

As everyone dont knows, because I dont say to anyone, I try make more smart chase function for monsters. Yes, Zscript.
So I forced every monster spawn warping child actor at its target. And I want to stop its warping if it master and target dont have direct line of sight. How make it?
Meaning is if player hide from that monster it start aproaching to this dummy actor, last place where monster see him target. This is more logical and realistic than "I smell you through all walls and >9000 unit of map units, n'wah"

The child's target or the master's target?

Regardless, use CheckSight in the child:

Code: Select all

if(master.CheckSight(master.target, SF_IGNOREVISIBILITY))
{
 //Perform warp
}

SF_IGNOREVISIBILITY ignores if the actor is +INVISIBLE or renderstyle none and such.

That works, thanks.

Now, about some hit from 90.
If monster chose target and it is behind map "table", or other obstacle through he can see it target but cant walk like grid, it start spin round and round try find way to target. What I say...everyone already knows how monster lost betwen three barrel.
How make monster choose right direction where walk to bypass an obstacle and face it target?
I already have some ideas, like if monster stuck in the way to its target it start spam above the floor harmless hitscan attack, puff from which start spam same hitscan attack and iterate it until some hitscan attack hit curently monster target. But I imagine how much processor time that will take for one monster. And monster in doom wad rarely walk alone.

I heard that Zscript have function BlockLinesIterator, but at wiki and known to me Zscript mod its not represented. So I dont know how it work, how work with this and even dont know is that the function what I needed.

How make flying monsters fly directly to its target, not "change a little X-Y coordinate, then little change Z coordinate, repeat" like they walk/fly invisible air stairs, which looks jerky?
