Do you interested in ready to use features for modders?
I.e:

* Radars of aircrafts can have not 100% chance to detect UFOs. https://github.com/SupSuper/OpenXcom/pull/932

* Hyperwave decoder used the rule "radarChance" too. https://github.com/SupSuper/OpenXcom/pull/931

* User can change rules of max view distance, max view distance at dark, max darkness to see unit. https://github.com/SupSuper/OpenXcom/pull/904
  Max view distance at dark depend of armour that you wear.

* Ammunition for HWPs used the same rules as for aircrafts. https://github.com/SupSuper/OpenXcom/pull/895

[Yankes]

Yes, when I get some free time, I will look closer on your features.

[Dioxine]

While you're at it... and it seems this project might be indeed what modders are looking for (I am very reluctant to custom .exes, but... so many possibilities are not to be scoofed at! As long as it can maintain the level of stability as the standard OXCom)...

https://openxcom.org/forum/index.php?topic=2788.0 - hope this isn't too convoluted, but I've come up with system that'd allow to create all sorts of "shield" items with only a short ruleset list of features and no new in-battle properties of items. Maybe you can salvage something out of it.

Another major thing would be allowing 4 weapons per craft, adding a (type) property to weapons and array of allowed types to slots, and allowing these weapons to modify the existing stats of the craft.

I just hope you won't get buried under a mountain of requests that are inevitable to follow and keep it simple, since it could mean a start of something really big...

[Solarius Scorch]

This is an immensely interesting project, and as a modder I am very excited about it, but my concern is that it might too early go a different way than the basic openxcom. In other words, it's an Openxcom 2.0 that might be lacking functionalities that will show up in the future nightlies.

Therefore I think it's essential to incorporate all openxcom nightlies to this, ASAP. Otherwise we'll have competing codes, and that would be counter-productive and perhaps even destructive to the community.

I think it would be best if features implemented here would later be merged with the basic openxcom, as a "2.0". But that depends on the devs.

[Yankes]

I will try keep backward compatibility with basic OXC. Best would be if any mod could work with my version without any big rewrites.

How much more freedom for Modders... THis much https://openxcom.org/forum/index.php?topic=2743.0 

[Dave84]

As a lurker I had to make an account to say how exciting this idea is. I've downloaded many of the mods here and made some changes of my own, the ability to have custom damage types would open up the possibility to make much more interesting weapons. I've already looked at how the ruleset would work and thought of some changes I would make by giving different weapons custom damage types:

Grenades would do less damage to terrain, they're meant to damage living things rather than walls (applies to alien grenades specifically)
The opposite could apply to high explosive.
Stun weapons should do a small amount of health damage, and possibly cause fatal wounds.
Some new weapons could do 50/50 stun and health damage, and/or cause a larger hit to morale.
(some) armour piercing weapons could be made to be actually armour piercing.
Perhaps plasma weapons could do a large amount of damage to armour and lower morale but not so much to health, there would be more chance to survive a shot but be significantly wounded and more vulnerable afterwards.

The possibilities are nearly endless, can't wait for the exe!

[Solarius Scorch]

Greetings, Dave.

(Sorry, couldn't resist. )

Grenades would do less damage to terrain, they're meant to damage living things rather than walls (applies to alien grenades specifically)

This could technically be achieved by cutting the explosion power by half and then increasing vulnerability of all units in the game by 100%, but that's a very dirty solution and would create problems with blast radius. It could be done with a special flag:

Code: [Select]

terrainDamage: 0.5
(multiplies damage to terrain by 0.5)

Stun weapons should do a small amount of health damage, and possibly cause fatal wounds.

Yep, as long as it's costomizable in the ruleset.

Some new weapons could do 50/50 stun and health damage, and/or cause a larger hit to morale.

This is relatively unlikely, since AFAIK the battlescape code is very hard to work with. Someone would have to crack it first.

(some) armour piercing weapons could be made to be actually armour piercing.

hell, even I am afraid of going this way.

Perhaps plasma weapons could do a large amount of damage to armour and lower morale but not so much to health, there would be more chance to survive a shot but be significantly wounded and more vulnerable afterwards.

Nah, that's just lunacy. But I'd like plasma to cause fires (not my idea, but can't remember whose).

I think about shields but I don't have jet elegant solution for that. 4 weapon is in TODO list (basic functionality is done but not merged jet).

Tracking temporary buffs require special system for handling it. OXC don't have any thing like that. Right now I stick to ready or easy implementable features, because of this buffs are outside current scope.

Most of things form your list is working, only direct morale change is unimplemented.

Hi Yankes and Solarius

I should have explained better, my wish list was what I thought could be modifiable using the Unified Damage Types from here https://github.com/SupSuper/OpenXcom/pull/938, which I assumed was was included in this mod. Like I say I've been lurking for a while, I read the link before and thought it looked cool but I'm not able to compile the code so was hoping it would be included in the nighties or released as an exe at some point.

As for changing plasma weapons, my thinking was it could work a bit like halo, where plasma weapons are quite good at destroying armor but not really much better than human weapons other than that. It could make things more interesting, although I admit it would make the game easier if plasma weapons weren't as good. But I get bored of everything being one-shot kills, so some way to make a weapon more likely to cause severe damage but not kill outright in one shot appeals to me.

[Dioxine]

You can make it work with the current ruleset options, simply adding resistance to plasma to all unarmored/lightly armored targets, whatever sense does it make

[NeoWorm]

Yes - this is exactly what a modder needs.
When (or if) you get to implement ruleset defined view distance I would have one more suggestion related to it.

My two cents - I would prefer to keep backward compatibility even if it means not implementing certain mods. Keeping track of odsolete versions to play certain mods is NIGHTMARE - look at Minecraft beta mods or some older DooM mods like Zanzan DooM.

But you're asking for this when there is a code fork that will not be merged, or it's simply not sure it will be.

My take on the thing is that once TFTD support will be in beta and only bugfixes will have to be stapled down....that could be a good time to pull most of the feature requests for OXC, at least concerning the UFO part.

I see no reason to fork away at this point risking incompatibilities with TFTD specific code.

Of course I do NOT mean "do not work on this", but I'd play along the lines of doing something you're confident it will be POSSIBLE to merge, and not divergin already.

Of course I don't know if this is at all possible, eh.

The view distance mod is backward and forward compatible with regular version of OpenXcom.
