Hello Yuoki,

I've fixed your code for yi_engines. What you were trying to do with on_tick was not allowed so that is why your modifications did not work. :) Don't blame the fluidboxes either. It wasn't their fault. Anyways, I fixed your logic as well as compressed the code to a more manageable form. I hope you will like the modifications. It should be doing what you wanted. As an added bonus, your buildings are now blue-printable and will work when placed by robots.

Code: Select all

require "defines"

game.on_init(function()

end)

game.on_load(function()

end)



-- following code by Fatmice, used with permission
game.on_event(defines.events.on_built_entity, function(event)
	Registration(event.created_entity)
end)
game.on_event(defines.events.on_robot_built_entity, function(event)
	Registration(event.created_entity)
end)
game.on_event(defines.events.on_preplayer_mined_item, function(event) 
	Unregistration(event.entity)
end)
game.on_event(defines.events.on_robot_pre_mined, function(event)
	Unregistration(event.entity)
end)
game.on_event(defines.events.on_entity_died, function(event)
	Unregistration(event.entity)
end)

function Registration(entity)
	if entity.name == "y-gearbox-power" then
		if global.YGBX == nil then
			global.YGBX = {}
		end
		local yegearboxen = {}
		yegearboxen[1] = entity
		table.insert(global.YGBX, yegearboxen)
	elseif entity.name == "ye_overheater" then
		if global.YFYO == nil then
			global.YFYO = {}
		end
		local ye_overh = {}
		ye_overh[1] = entity
		table.insert(global.YFYO, ye_overh)
	elseif entity.name == "ye_sturbine" then

			global.YSTT = {}
		end
		local yesturbines = {}
		yesturbines[1] = entity
		table.insert(global.YSTT, yesturbines)
	end
end

function Unregistration(entity)
	if entity.name == "y-gearbox-power" then

							["temperature"] = 90
						}
					end
				end
			else
				table.remove(global.YSTT, k)
			end
		end
	end
end)
I also modified the steam to mechanical force recipe. You vaporized 10 units of water so you should get back 10 units of water when you condense it, not 2.

Code: Select all

	{
	  type = "recipe",
	  name = "ye_steam2mf_recipe",
	  category = "yrcat_turbine", -- steam to mechanical power
	  enabled = "true",
	  energy_required = 0.10,
	  ingredients = {
		{ type = "fluid", name = "ye_steam" , amount = 120.0, },
	  },
	  results = {
		{ type = "fluid", name = "y-mechanical-force", amount = 10.0, },
		{ type = "fluid", name = "water", amount = 10.0, },
	  },
	  icon = "__yi_engines__/graphics/mf-1.png",
	  order = "0", group = "yi_engines", subgroup = "yie-engines",
	},

Just as a quick piece of balancing feedback:

There's a lot of accumulators in this pack, and while they do have differences those differences are currently not pronounced enough.

The flywheel for example is a great example of something different, high capacity, high discharge, but low charge rate. Only problem is the charge rate is still high enough that I never have any problem charging it, it's done by the time the sun is completely up even on an outpost where a pair of flywheels were providing most of the charge. The charging rate for that could be dropped to present some interesting challenges - I'd like to see circumstances where you'd want to set up the flywheels so they only cut in when the grid is struggling, because it takes maybe a whole day to recharge them otherwise.

The pink crystal accumulator seems to be generally the best, which is fine, and the various yellow crystal accumulators under that are just a better version of their non-crystal cousins. That's okay, but the upgrades seem a little minor. I'm not too sure here, because I haven't really bothered with them yet - the basic versions work just fine for my purposes.

The vanilla accumulators seem to be taking the lowtech, low capacity, high charge/discharge niche, and I like that.

There's possibly a niche spare that could be filled with something with a medium capacity, high charge rate, and very low trickle discharge - something that would keep going long after all other accumulators have quit, just so you have SOME power.

Hope those thoughts help!

@Fatmice

Thank you very much. I have tested the code and add 1 line to prevent a error. So next release will contain your code and the WIP-Machines. And you are right, 10 Water in, 10 should come out. The idea was to use this condensate/or a lower MF-output to self-feeding the engine itself and separete this from the energy-network. but of course without the heater the system collaps and can't restart without energy for the heater. also it's possible to use the heater-steam for a steam-engine. using this steam-turbine provides MF for the big generators.
so it's more a player-decison how complicated the power-generation can be.
it's more experimenting - i think some other mods have build this cycle in better ways.

This thoughts help.
planed is the following because feels like every mod adds accumulators and in modpacks YI-Accumulators not compareable
- remove of small accumulator - only SCD (better graphic)
- only 1 medium accumulator (best graphic wins ^^)
- 2 big accumulators, 1 huge
- remove crystal -> changed to huge
- the flywheel will get a new recipe, focus on mechanical parts and the stored energy will be lowered.
- from Addon-PFW comes later 1 or 2 extreme high capacity-accumulators (battlefield energy-stockpile)
- from Addon-YI-Engines a fluid-based accumulator setup (if i can get it working)

factorio has no more then 3 energy-levels ... if it possible to assign level-numbers (1-10) then i can make different settings.
the flywheel charge-rate equals vanilla-accumulators. and it's designed to capture high-energy spikes (defense) with longer pause between.

Yes, I know what you are trying to do with the water->steam->water loop. I have loops in my mod as well, a bit more complicated but same principle.

I've already exploited this mechanism with "my own engine". =) Have a look.

All nicely fitted in one chunk, blue-printable.

115 MW in one chunk. 12 MW upkeep, 103 MW net. A beacon with efficiency module 3 next to each of the overheater will shave another 4 MW from upkeep. ;) So 8 MW investment leads to 103 MW of net production? Yes please. :!:

yep very exploiting :) - but the way is the goal - building, thinking, improve stuff and setups
it will not fit in a chunk, because the graphics should also look as they can deliver that much power - so the 3x3's to small :)
and building this piece of machinery should be a extra challange ^^

after the code works it's easy to balance this over adjusting fluid-amount, temperature or heat_capacity.

Nothing so complicated, you only need to adjust from code. Just change the temperature of MF that's produced by the steam-turbine to balance how many rensuir can be run on it.

This is super nit-picky, but I've just noticed and now cannot unsee...

When oriented vertically, the current Steam Turbine graphic has two cogs on the end, and one large toothed wheel in the middle. These cogs turn in opposite directions, meaning one of them is wrong and would not mesh with the toothed wheel, and it looks like they're intended to do so.

They should both turn anti-clockwise since the rest of the turbine is turning clockwise.

This is because the background art is static. Of course they will not be that way when he replaces it with the real sprite.

you the frist one which takes a closer look at the graphics. it's true small left and right gogs should spin same direction, but as i made this animation i made little mistake, i mirrored the left cog. this makes animation easier, because i only need to animate the left side. After finishing and viewing this ingame i found this annoying but not gamebreaking ;) Also the cogs does not spin in correct speed because for animation i need to make sure i end always with a tooth at top, independently how many tooths i choose - if i don't do this, this cogs will jump - looks more weird as wrong direction.
Inside of the gearbox is also mirrored, but i spins correct directions.

yep the graphics above only placeholder for easier experimentations and the steam-turbine for this will look very different.

This is a really interesting mod for Factiorio, and Research would make it even more interesting.
Even though you like things simple; that can still be the case, all you would need is a config setting
in your ini file that would say "Disable_Research = True" and if its true, give you all the technology.
Otherwise you can research it bit by bit :)

Your storage bunkers are not accessible by the circuit network - clicking them with a circuit on the cursor just opens them.

Edit: Also, the shadow on the UPS flywheel is too dark compared to other shadows in the game.

Did you try to use this kind of code for timing:

Code: Select all

if ( game.tick % 5 ) == 0 then ... end
Replace 5 by interval you want the functions to be executed?

You seem to be doing lots of work with those ticks that seems not really needed :D

Modulo is defined as a % b => a - math.floor(a/b)*b, isn't that already even more work than just subtracting? ;)

That's how it's defined for humans, but there are optimizations for some hardware, especially on powers of 2.

That said, we're using lua - I doubt lua optimizes particularly well no matter the hardware.

THAT said, computers are ridiculously fast nowadays, and can perform millions of divisions per second, an extra couple per tick isn't going to slow anything down much (unless it does - but solve that when you come to it. Basically, you can afford to make things clearer at the expense of a division here and there nowadays unless you're running on an ARM or something embedded)

If you really cared, you'd need to profile it. That if then else statement isn't free either.

If you've got something that works, keep using it. If not, go for something simple, and if you need more performance optimize it then :)

I can't say much about lua - but modulo is one cpu instruction especially when done on integer. Probably irrelevant for lua :D

And when talking about those... few math operations are most likely to be faster then anything involving conditional - but my knowledge of CPU's architectures might be tad old (branching has some drawbacks).

And all that counting you are doing looks.. error prone. Modulo is simple. And with performance it's as Darloth said - most likely irrelevant.

In either case, conditionals are involved (there is no going around it) and I just looked at modulo implementation for lua. It used C math library, obviously since lua is just a virtual machine, and is indeed

Code: Select all

lua_Number luaO_arith (int op, lua_Number v1, lua_Number v2) {
  switch (op) {
    case LUA_OPADD: return luai_numadd(NULL, v1, v2);
    case LUA_OPSUB: return luai_numsub(NULL, v1, v2);
    case LUA_OPMUL: return luai_nummul(NULL, v1, v2);
    case LUA_OPDIV: return luai_numdiv(NULL, v1, v2);
    case LUA_OPMOD: return luai_nummod(NULL, v1, v2);
    case LUA_OPPOW: return luai_numpow(NULL, v1, v2);
    case LUA_OPUNM: return luai_numunm(NULL, v1);
    default: lua_assert(0); return 0;
  }
}

Code: Select all

/*
@@ The luai_num* macros define the primitive operations over numbers.
*/

/* the following operations need the math library */
#if defined(lobject_c) || defined(lvm_c)
#include <math.h>
#define luai_nummod(L,a,b)	((a) - floor((a)/(b))*(b))
#define luai_numpow(L,a,b)	(pow(a,b))
#endif
I count 4 operations just for the modulo: negation, division, multiplication, and a floor (which is at least two more operations). Add on top of that the compare operation

Code: Select all

LUA_API int lua_compare (lua_State *L, int index1, int index2, int op) {
  StkId o1, o2;
  int i = 0;
  lua_lock(L);  /* may call tag method */
  o1 = index2addr(L, index1);
  o2 = index2addr(L, index2);
  if (isvalid(o1) && isvalid(o2)) {
    switch (op) {
      case LUA_OPEQ: i = equalobj(L, o1, o2); break;
      case LUA_OPLT: i = luaV_lessthan(L, o1, o2); break;
      case LUA_OPLE: i = luaV_lessequal(L, o1, o2); break;
      default: api_check(L, 0, "invalid option");
    }
  }
  lua_unlock(L);
  return i;
}
All of that just to operate

Code: Select all

if ( game.tick % 5 ) == 0 then ... end
Whereas, my tick counting is simply: compare, assignment, and a negation. I don't see how counting is anymore error prone than modulo. Indeed, all primitive operations are themselves either bit counting or bit shifting. Performance wise? You won't notice anything until you use very large numbers and by then modulo is limited by the size of the type of game.tick, which I'm guessing they will use a unsigned long (that gives you 2.28 years worth of game time before it overflows), whereas my counting method don't matter since my method never overflows, even if game.tick is ungodly big_int and limited by system memory.

Youki, if you would like, I could localize your items for English. Your english isn't bad, but a few of your item names, need adjusting.

okay ... but how you would explain all the fantasy names ? ;) - but of course you can try your best
don't use the german-translation as reference.
thanks new factorio f0.22 you don't need make any description because it destroys the right info-window if it's longer then maybe 24 chars.

thanks for all other postings !
