I see now. Well thx u guys for answers. And sorry Matt115 if i angry u somehow ^_^. English is not my first language too btw so its totaly fine ^_^.
Well well. now i even kinda hooked in
i totaly didnt expect here to talk about technicall staffs and ways of realization/implamitations but i'm 100% down for it
especially if this even gonna up chances of getting some of ideas in game.
Okay so. Before we start, as i looked up they are making this game in Unity if nothing changed? If yes this gonna make me more clear of things and how it works. And btw i already working with Unity as well for 3 years so thats nice.
In terms of Unity that is much more than I know, I have only second-hand knowledge.
I think first of all i gonna go back to things i listed thats is not touched by any limits in game u mentioned and so they can be implemented right away verry fast and easy.
Well its not. In unity u can just aplly diferent color tint to the matterial it self wich is uses texture and thats it.
I assume your are talking about door color. If blocks like doors should have different colors then you also need to store the color in each block in memory and on disk. If there are no bits left for that you would need a lot bigger changes to the code and data than you are assuming. And increase size of the data that is transfered all the time from disk to RAM to VRAM.
In previous alphas you could paint any block with a number of colors. In A20 I can't find them anymore (either I have just been unable to find the right UI element or the colors were scrapped to make room for more textures in the world).
u dont have to change texture on this matterial for this. In fact i think this is exact how they already doing with lots of things in game like: bed rolls, chairs, armor, weapons, and so on... So for example if we saying only about adding this same feautre to the blocks or other furnitures as well - then this is definetely doable and no need for more textures.
Okay but what about thigs like nyew type of looks for doors for example or new furnitures and stuff. Well actualy there is already more then enaugh textures i already saw in game that can be used for this and no need new ones. I defientely saw - smooth wood textures (and other types of wood), lots of diferent typo of textures for metal (smooth and not as well same as rusty one and shiny one). So again they can just reuse this texutres for any things there is already more than enaugh in game for 100% sure.
Well, paint a door in "cobblestone" and tell me how it looks
. (PS: If you don't know about painting: You can find a paintbrush in game and apply texture to any surface)
And for example as i told about ovens and washing machines or coffy machines or other things - this are even already in game. just not usable/interactible. (well only like inventory. just like destroyed versions of crafting stations). Even for the rain collector there is definetelly all textures i already saw in game as well as some plastic coating kinda materrial. The other posible problem that even tho there is texutres in game that seems like can be used for many diferent objects the realization was made verry specific to use on this exact one object and if this texture gonna be applyed on dieferen objects/shapes - its gonna look messy. Then ofcourse littel more work gonna have to be done but its still pretty easy and dont need to create new textures. For example the way to fix - is to split the texture in different little ones and use them separate or to rearange the basic one.
For the developers there is not only the question of whether something is doable, but whether they want to invest their very limited time in such features and what features to leave out for that. For example a working electrical oven is something the developers have talked about (if I remember correctly) and would even like to implement one day. But what kept this idea far down on their priority list is that it is just a cosmetic addition that doesn't allow for new ways to play the game. In fact you can find lots of mods that already implement working ovens, it isn't difficult.
TFP seem to have a design goal of keeping the vanilla game somewhat clean of duplication. So there is not a pistol AND a P225 in the game because both would do and feel too much the same, it would not get them a new way of playing the game.
Instead they leave this field to modders. And in fact if you want lots of almost identical but still different looking weapons, you will find lots of mods for that. I'm not saying duplication is inferior stuff, having lots of decoration is nice, but it it something hundreds of modders can do much better and faster than a small dev shop.
In other words, TFP wants a "clean" base game as vanilla for new players to learn the game, and they work on features that need changes deep in the code. And the modders are there to enrich the game for all players that stay with the game, provide the fluff but also new features that can be built on top of the feature set the base game provides.
About new bioms/flora/fauna. Well for this one even tho new textures (for example for fishes) are gonna be needed, cause its seems like i didnt saw any in game, its not like they gonna add verry much compared to how much they already have, and we dont ask for much, even 1 new at a time will bring times more of joy in game.
They have said for a long time that new stuff for the water needs a water physics overhaul first since they were not satisfied how water works at the moment, how it flows etc. And luckily for you they have a programmer on this task right now for A21 (or A22 or even never if that programmer doesn't find a satisfying implementation)
Once that is in, maybe we get boats and zombie fish.
And seeing they'r last changes to 7dtd - how they remodeled all zombies in last patches to new HD textures and even added new ones and planning to add raiders wich is also more new textures - they definetely far from bottlenecking the minimum requairments or Unity limits.
Sure, but those are their priorities. HD textures seem to have been important to them and I can think of a few reasons:
1) Now that many players have 4k displays HD textures are needed so the game doesn't look @%$#ty on them
2) New players will compare this game to AAA games or even indie games in terms of graphics quality and then 7D2D shouldn't look like coming from 2001.
3) They might want 7D2D to look as good as possible themselves. Maybe they noticed themselves that they don't like the old textures anymore.
Bandits are very important to them because they promised them in the kickstarter. This is THE top item of their priority list. Even if they have to blast away the last bits of their performance budget and borrow some more they will do that. I assume they would even increase minimum specs if that needs to be done, just for bandits.
Their priorities. I guarantee you, if you were developing your own game (and with 3 years unity experience, maybe you alread have) you will generally put your own priorities in front. And carefully select which ideas from the community to follow.
So arguments like: "TFP did expend effort and performance for A, why not B?" can be explained easily: A is not B
Btw also would be greate idea to use diferent tint of color on clothes materials of the zombies to make less of the "clones" (againe - no need new textures. just using same one) would be HUUUUUGE as well actualy
.
An idea often proposed and even though TFP don't like the current situation (of just a few identical zombies) there seems to be no easy way to do that, yet. With all the code added for bandits and an overhaul of the player clothes/armor system planned this may change in the future.
Even tho saying about bioms i honestly dont even know what kind of to add more and its still be "realistic". XD
Just try out alpha16. At that time we had two forests types, we had plains and the burned biome was separate to wasteland. Now consider: If for whatever reason TFP removed those biomes (which got lots of protests from forum users) those reason must be very compelling. They won't just reconsider because someone posts this great idea to add more biomes
For me its all enaugh as well. The only rly watter and underwatter stuff rly feels empty and its rly sad. Also they can btw made player finaly be able to swim with just one adjust on slidebar in unity (10 seconds of work) would be greate as well. (not saying about animation for swimming - but this is not the most important. they can add it lately even if they need it. for me - i fine without it, only wonna speed as if i swim in watter and not in goo rly XD
).
Okay so radio is doable and will be HUUUUUUGE as well. Its basicaly gonna add WHOLE new MOOD for the base. more then ANY blocks or furnitures combined.
Maybe. Sounds to me like something a modder might add or a feature for an addon. They already have a large list of things they still want to add until release and even need to prune THAT list. A radio is nice to have but essentially fluff, it doesn't provide a new way to play the game. Yes, they might underrate the effect to players like I do right now
+ All the stuff for cooking i mentioned as well is pretty much doable because its only patches in recipes and GUI and updating loot drop % chances. Mb not for farmin. To add more crops. But what, i mentioned like 2 more crops? and we already got it that they far rom bottlenecking. and texture for crops is TIMES less than it is for raiders or zombies.
Sure. A year ago Madmole asked for interesting cooking recipes to add to the game. And they afterwards did add recipes. Which tells me they are probably satisfied with the amount of cooking recipes in the game. Feature done. If you want more recipes there are already lots of mods providing them.
Did we establish that they are far from bottlenecking? Don't think so. They definitely have a limited budget and they have a plan what needs to go into the game (for example bandits) and depending on implementation a part of that limited budget might already be reserved for those planned features. Apart from that you will find lots of forum posters complaining about the game being too slow or dropping FPS into the single digits on horde night or in the city. It isn't clear at all if there is a budget left at all.
Diferent colored lights? - same as with TInt color changing for existing ones. Adding neon lights tho not gonna be 5 minute job but i guuueeeeess its still doable. (againe watching only one what they doing and adding).
And so now to the biggest and strangest part...
WAaaaaait a second. . . so 64 creatures FOR WHOLE GAME? O_O not even per player? O_O
Now this is rly feels verry weird. cause its not like the creatures have some rly complicated and hard life/tasks/logic that they have. Basicaly just wandering + pathfinding.
So this is rly sounds like something not rly optimized.
You can easily increase the limit if you have a current PC. But get yourself an old PC near minimum specs and try again. Here is some info about the jobs system directly from Faatal who is the lead developer and also the main AI developer. If you want inside information about the game, go into his profile and read his past posts. Lots of informative stuff in there
https://community.7daystodie.com/topic/22366-alpha-20-dev-diary/?do=findComment&comment=464476
Do you have experience with voxel games? Voxel-based games seem to need a lot more resources than typical games.
Now Unity still has its main game loop in one single thread. And according to Faatal some of the limitations are because some work can not be moved to other threads.
Furthermore there are bandwidth limits on data transfers. On older PCs you can notice this when driving with a motorbike and the new area isn't loaded fast enough, leading to holes in the world or you simply stopping in your track. Actually in vanilla this determines the maximum speed of vehicles.
What I'm saying here: From the outside and playing with a unity mockup or a smaller game or a game with a fixed world you can easily claim that hundreds of zombies should be no problem. But when you build up a complex game with features like a completely dynamic world and voxels that are not really supported by graphics engines you may hit limits you haven't seen yet in whatever game you have done in the same engine.
I myself don't have any actual experience at all with Unity. I can only tell you second hand knowledge as heard from the developers and making my own conclusions from this.
Also it sounds like they not implemented DOTS and jobs system in theyr game. Because even if we not try to optimize things. Just implementing DOTS + jobs system that unity have - it can up the limits if not 1000 but 100 times for sure. Actualy, knowing when first time 7dtd was created, and when DOTS and job system got its finaly good for use implementations in Unity, probably chances are big its not yet used. And if yes. Then actualy this could improve whole game switching to DOTS in any aspects in game. Unity dev's even made it so u can change already existing codes to Hybrite DOTS/jobs systems and monobeh, so no need to REwrite EVERYTHING from scratch, wich is the real BLESSINGS for all devs in the world.
i gonna left this part as "IDK if doable" as i dont know whats going on in here for now.
And with all of that's its seems like still if not all 100% then more than 95% of all things i mentioned is rly verry doable actualy. (well at least for how i see).
It is not a question of doability. Almost everything is doable with tons of effort put into it. But the developers have to weigh effort against how much they want such a feature. And when you propose an idea you have to compete with features where the developers think they can get huge improvements out of minimal effort. You have to compete with their best ideas, and they have already said they have tons of ideas and they had needed to drop most of them because of not enough time and effort.
Also as said before Fun pimps already made lots of optimizations with last versions of the game. So who knows mb the limitations of wich they were talking in pasts is already long gone. And so some of suggestions mb can be revisited?
P.s.
Actualy this is great idea as well. I would love even this kind of variant.
And ooo oo
Mb can be added the bee hives as well with same ideas.
Woaw i actualy love this topic now
grate talks.
loving it
. I didn't say anything about removing something from 7dtd, just adding something. No one forces you tu use it if you don't want to 
. U can still play just challanging u'r self in any way u wonna with all u'r dificulties that u wonna. 
). even in general - adding more stuff = adding more hours for ppls to play with this new stuff's in game. And adding more "quality of life" stuff adding even more hours as it always show in many games throu all of the gaming history. Because ppls then just like to even be in game and spend more time even without the goals - just to bring joy and pleasure. And also i'm 100% sure this would OPEN HUGE whole new niche for the multiplayer comunity posibilities.
sadge. And yeah not everything would fit probably (tho it can still depends on designe i guess) but my general goal was to create basic idea of what's left behind. Like we could'v said "quality of life" improvments/update. 
... well i thought suggesting easy add-on's will have more chances of getting in game. and this ones is rly brings mooore ways of playing.
