Modifying the THC on body parts

[Josan12]

Timeslip in all his/her wizardry has made it possible to modify the to-hit-chance on body locations in FO2. *gets down on knees and praises Timeslip*

Needless to say, messing with any of these figures would dramatically change the game difficulty.

I've long been thinking of a little mod that makes the eyes between 50 and 100% harder to hit. Does anyone else feel that easy eye shots make FO2 way too easy?

Also - does anyone know if the AI NPC's make called shots (to the eyes) ??

However, from my experience mods that make the game more challenging seem to be rather unpopular .... personally i love a challenge.

Any opinions on this?

Called shots could use some work. It has always bugged me that when you aim for the eyes and you would miss them, the shot would always miss the target completly. I rather would see that there also was a chance that the rest of the body would get hit.

As for the called being to easy; I think there should be a bigger penalty for called shot when enemies are far away. A legg and arm could still be doable, a head would be dificult but the eyes... imposible (sniper guns needed)

Creating other NPC's to aim more is a nice idea to, makes battles more chalanging

Yes they do. I once got blinded by one of the unarmed Enclave soldiers in the puzzle room level.

In ai.txt, the called_freq parameter controls how often they make aimed shots. I'm not sure if a value of N means an N% or 1/N chance; the wikia page needs work. I'll guess that which limb they target is random, but also considers min_to_hit so that they don't try to make impossible shots. Increasing critters' skill levels will let them make more head/eye called shots.

For another challenge, modify some critters to give them a critical table bonus. In addition to generally worse effects, this enables instant-kills to the head, eyes, and torso (uncalled).

What he said. Its okay to shoot someone's eye when his distance to you is five meters, but its totally ridiculous to shoot a eye from twenty meters onwards. You are more likely to hit the head, the neck or miss. Unless you have a Scoped Hunting Rifle or Sniper Rifle and high Small Guns skill, then it makes sense.

I think long-range eye shots should be something doable only with precise snipery weapons, good shooting conditions AND high-skill (more than 150%), but even they should not be garanteed insta-hits even by the endgame.

By the endgame (New Reno and beyond) eye shots get too easy unless you play with a low-PE or retard character (which probrably has lower skill than the usual diplosniper).

And making NPCs aim more is a excellent idea. Skilled Soldiers - Vault City guards and patrols, Mercenary Raiders, Unity patrollers, NCR Rangers and Enclave Troopers - Should use more aimed shots.

A script similar to this should give a penelty for aiming at the eyes from long distances.

//hs_tohit.int
procedure start;

procedure start begin
	variable hitchance;
	variable target;
	variable attacker;
	variable bodypart;
	variable tmp;

	if(init_hook) then begin

	end else begin
		hitchance:=get_sfall_arg;
		target:=get_sfall_arg;
		attacker:=get_sfall_arg;
		bodypart:=get_sfall_arg;

		if(bodypart==6) then begin
			//eyes
			tmp:=tile_distance_objs(target, attacker) - 3;
			if(tmp > 0) then begin
				hitchance := hitchance - tmp*3;
			end
		end else if(bodypart==0 or bodypart==7) then begin
			//head or groin
			tmp:=tile_distance_objs(target, attacker) - 5;
			if(tmp > 0) then begin
				hitchance := hitchance - tmp*2;
			end
		end

		set_sfall_global("ts_hitpc", hitchance);
		if(hitchance>95) then begin
			hitchance:=95;
		end
		set_sfall_return(hitchance);
	end
end

There's a lot more you could do than that, checking the players weapon and adjusting accordingly for sniper rifles etc. This was just a test for if it's possible.

I was trying to get it so that if you had low hit chances, then you would accidentally hit other bodyparts. (Hence that set_sfall_global bit; that was used in hs_afterhitroll.int to decide which bodypart you hit, with you only being sure of hitting the correct bodypart at 150% uncapped accuracy.) I've still got a few kinks to work out with that script there though.

Hey, thanks Timeslip! I would love to play around with this and help tweak it but unfortunately i'm rather hamstrung by my beginner level understanding of scripting.

What part of the above script would i take to only increase the difficulty of hitting the eyes by say ... 50%?? (I don't really want to mess with the range thing as some players don't like mods to change things too much)

I like the idea of having a (small) chance of hitting other body parts when missing a called shot but doesn't this run the risk of actually making the game much easier by removing the risk of making called shots? (i.e. paying the price of missing completely for the potential benefit of scoring a more devastating shot)

No need to script for that. Just change the BodypartHitMod6 line in ddraw.ini from -60 to -110.

Actually I had it set up so that only hits had a chance to be retargeted; misses continued to miss. That way aimed shots are even harder than normal, with none of their penelty removed.

Oh i see. Very clever I misunderstood. I like this idea - i'll test it out and report back.

Looks awesome. When we will see this being released?

 

[Josan12]

...... but now i realise i can't compile it becuase i use FSE and it won't recognise the init_hook command

Could someone else possibly make an .int of this for me please

 

[Timeslip]

...... but now i realise i can't compile it becuase i use FSE and it won't recognise the init_hook command

Then replace the sslc that comes with fse with sfall's sslc.

If you use fallout script editor, you can extract compile.exe and dos4gw.exe to its \binary folder, or extract them somewhere else and change your preferences in FSE to point there. FSE doesn't seem to be able to tell when errors occur when using this compiler, so I'd recommend compiling by hand if possible.

Like that says, if you're using fse with my modified sslc, it always says that scripts have compiled successfully even when they haven't. (The compiler that fse uses normally is the dos version, hence why I include the fake dos4gw in my sslc download. It's not a good enough fake for fse to be able to understand its errors though.)

Well i'll be .... it worked. So if you'll indulge me: am i correct in understanding the new hstohit.int will somehow be read by the game via sfall and it's magical dostuff code?? Therefore overriding the what the game would normally do with called shots and do what sfall tells it to do instead?

it's a mystery to me, but interesting.

Who knows. Depends on how droopy my learning curve is and if Timeslip keeps babying me

I'll report progress tho ...

yup. (except that it's hs_tohit.int. The underscore is important.)

Read the hookscripts.txt that came with sslc.
