I have the below function that adds resistances to an entity type.
I'd like to modify it to only apply the change to resistances, IF the entities current resistance is lower that the resistance % I'm trying to add.

So let's take the standard inserter as an example. If I'm trying to add Physical resistance of 10% to the inserter, but it currently has 20%, is should not add my change. If it only currently has 5%, then implement the change.

This is the current function:

Code: Select all

-- Adds a resistance of all damage types to an entity
function NE_Functions.Add_ALL_Damage_Resists(Raw,Percent)
	if Raw ~= nil then	
		for k, v in pairs(data.raw["damage-type"]) do
		
			local Resist = {type = v.name, percent = Percent} -- or you could use k, and not v.name
			for i,d in pairs(Raw) do
				if d.resistances == nil then d.resistances = {} end
				table.insert(d.resistances, Resist)
			end
		end
	end
end

I tries something like the below, but it was complaining I'm trying to compare two table values:

Code: Select all

function NE_Functions.Add_ALL_Damage_Resists(Raw,Percent)
	if Raw ~= nil then	
		for k, v in pairs(data.raw["damage-type"]) do
		
			local Resist = {type = v.name, percent = Percent} -- or you could use k, and not v.name
			for i,d in pairs(Raw) do
				if d.resistances == nil then d.resistances = {} end
				if d.resistances < Resist then
					table.insert(d.resistances, Resist)
				end
			end
		end
	end
end

It won't work like this.

You need to expand the if section in the middle and also iterate through resistances.
A bit hard for me to write it up from memory exactly but should be like this:

Code: Select all

            if d.resistances == nil then
                 d.resistances = {}
                 table.insert(d.resistances, Resist)
            else
                 local found = false
                 for _, resistance in pairs(d.resistances) do
                      if resistance.type == Resist.type and resistance.percent < Resist.percent then
                             resistance.percent = Resist.percent
                             found = true
                             break
                      end
                 end
                 if not found then
                      table.insert(d.resistances, Resist)
                 end
            end

I stand corrected, not currently working, but I'll play around with it.

Post me the code as it is and I can take a look on weekend if you can't get it to work.

Okay, I have two functions, One I got working, the second still not working for me. Currently the second one is overriding the first.
The first only targets one specific inserter. The second All inserters.
First: Working

Code: Select all

for k, v in pairs(data.raw["damage-type"]) do
	local Resist = {type = v.name, percent = 70} -- or you could use k, and not v.name		
	
				if data.raw.inserter["combat-inserter"].resistances == nil then 
					data.raw.inserter["combat-inserter"].resistances = {}
					table.insert(data.raw.inserter["combat-inserter"].resistances, Resist)
				else
					local found = false
					for _, resistance in pairs(data.raw.inserter["combat-inserter"].resistances) do
						if resistance.type == Resist.type and resistance.percent > Resist.percent then
                            found = true
                            break
						elseif resistance.type == Resist.type and resistance.percent < Resist.percent then
                            resistance.percent = Resist.percent
                            found = true
							table.insert(data.raw.inserter["combat-inserter"].resistances, Resist)
                            break
						end
					end
                
					if not found then
					table.insert(data.raw.inserter["combat-inserter"].resistances, Resist)
					end
				
				end
	
end

Second:

Code: Select all

-- Adds a resistance of a single damage type to an entity
function NE_Functions.Add_Damage_Resists(D_Type,Raw,Percent)
	if data.raw["damage-type"][D_Type] ~= nil then
		local Resist = {type = D_Type, percent = Percent}
		for i,d in pairs(Raw) do
			if d.resistances == nil then 
				d.resistances = {}
				table.insert(d.resistances, Resist)
			else
				local found = false
				for _, resistance in pairs(d.resistances) do
					if resistance.type == Resist.D_Type and resistance.percent > Resist.Percent then
                           Resist.percent = resistance.percent 
						   found = true
                           break
					
					elseif resistance.type == Resist.D_Type and resistance.percent < Resist.Percent then
                            resistance.percent = Resist.percent
                            found = true
							table.insert(d.resistances, Resist)
                            break
					end
				end				
			
				if not found then
					table.insert(d.resistances, Resist)
				end
			
			end
		end
	end
end

I think I found the problem. My different modules were conflicting with each other. I have the same function in NE Expansion and was only updating the NE Enemies one...

Will test some more later.

Posted: **Fri Aug 05, 2016 3:08 am**

Okay, it was not the functions in the other mods fault. For some reason I just can't prevent the second function from overriding the first.

Would it be per chance thatt you have the > and < there but there is no >=

So if it's already equal it will insert it anyway.

Good point that I should add the "=", but that's not the problem.
In NE Enemies I add 12.5% resistance to acid to ALL inserters:
NE_Functions.Add_Damage_Resists("acid",data.raw["inserter"],(25/NE_Difficulty))
Using this:

Code: Select all

-- Adds a resistance of a single damage type to an entity
function NE_Functions.Add_Damage_Resists(D_Type,Raw,Percent)
	if data.raw["damage-type"][D_Type] ~= nil then
		local Resist = {type = D_Type, percent = Percent}
		for i,d in pairs(Raw) do
			if d.resistances == nil then 
				d.resistances = {}
				table.insert(d.resistances, Resist)
			else
				local found = false
				for _, resistance in pairs(d.resistances) do
					if resistance.type == Resist.D_Type and resistance.percent > Resist.Percent then
                           Resist.percent = resistance.percent 
						   found = true
						   table.insert(d.resistances, resistance.percent)
                           break
					
					elseif resistance.type == Resist.D_Type and resistance.percent < Resist.Percent then
                            resistance.percent = Resist.percent
                            found = true
							table.insert(d.resistances, Resist)
                            break
					end
				end				
			
				if not found then
					table.insert(d.resistances, Resist)
				end
			
			end
		end
	end
end

In NE buildings, I've got a new inserter, called the combat inserter. I'm trying to add 70% resistances to it, using:

Code: Select all

for k, v in pairs(data.raw["damage-type"]) do
	local Resist = {type = v.name, percent = 70} -- or you could use k, and not v.name		
	
	if data.raw.inserter["combat-inserter"].resistances == nil then 
		data.raw.inserter["combat-inserter"].resistances = {}
		table.insert(data.raw.inserter["combat-inserter"].resistances, Resist)
	else
		local found = false
		for _, resistance in pairs(data.raw.inserter["combat-inserter"].resistances) do
			if resistance.type == Resist.type and resistance.percent > Resist.percent then
                found = true
                break
			elseif resistance.type == Resist.type and resistance.percent < Resist.percent then
                    found = true
					table.insert(data.raw.inserter["combat-inserter"].resistances, Resist)
                    break
			end
		end
               
		if not found then
			table.insert(data.raw.inserter["combat-inserter"].resistances, Resist)
		end
			
	end
	
end

Since inserters already have fire of 90%, it's leaving that at 90% and giving everything else 70%. Except for Acid that's still at the 12.5% above.
I've tested ND Buildings alone and it works fine, adding to lower resistances and ignoring higher resistances. So the problem is with the NE Enemies function.
The only real difference is the NE Enemies looks at the "Type" and thus all inserters and NE Buildings targets a specific one.

First one is broken - it uses Resist.D_Type while it should be Resist.type in the if statements.
Both also might broken in different way - in section where resist is smaller it does the table.insert. It should change resistances.percent to new value. With inserts it will add another table to resistances and then in depends on which one will factorio use.

If I change D_Type to type I get an error:

Code: Select all

function NE_Functions.Add_Damage_Resists(D_Type,Raw,Percent)
	if data.raw["damage-type"][D_Type] ~= nil then
		local Resist = {type = D_Type, percent = Percent}

                           --Resist.percent = resistance.percent 
						   found = true
						   --table.insert(d.resistances, resistance.percent)
                           break

                            resistance.percent = Resist.percent

                            break
					end
				end				
			
				if not found then
					table.insert(d.resistances, Resist)
				end
			
			end
		end
	end
end

I think I see what might be going on.
There are resistance entries with percent and ones with decrease.
So we also need to make sure that we are looking at percent one by cehcking if resistance.percent actually exists. And don't touch the decrease ones.

It would amount to this:

Code: Select all

function NE_Functions.Add_Damage_Resists(D_Type,Raw,Percent)
	if data.raw["damage-type"][D_Type] ~= nil then
		local Resist = {type = D_Type, percent = Percent}
		for i,d in pairs(Raw) do
			if d.resistances == nil then 
				d.resistances = {}
				table.insert(d.resistances, Resist)
			else
				local found = false
				for _, resistance in pairs(d.resistances) do
					if resistance.type == Resist.type and resistance.percent then
						if resistance.percent < Resist.Percent then
							resistance.percent = Resist.percent
						end
						found = true
					end            
					
					if not found then
						table.insert(d.resistances, Resist)
					end
				end
			end
		end
	end
end

Just gave this a quick try. Getting same error as above. (Just line 32 this time. )

Code: Select all

 if resistance.percent < Resist.Percent then

"Attempt to compare nil with number"

Thats because it should read:

Code: Select all

 if resistance.percent < Resist.percent then

Coding on "paper" is silly like that

Okay, that fixed the error, but still no luck. I'm starting to distrust myself, so I've attached the two mods so you can look for yourself when you have a moment over the weekend.
I'll be out for the next few days.

The code above is in Natural_Evolution_Enemies_6.2.0\libs\NE_Functions.lua
This is called in Natural_Evolution_Enemies_6.2.0\data-updates.lua lines 79 and 90:
NE_Functions.Add_Damage_Resists("poison",data.raw["inserter"],(25/NE_Difficulty))
NE_Functions.Add_Damage_Resists("acid",data.raw["inserter"],(25/NE_Difficulty))

In Natural_Evolution_Buildings_6.2.0\data-updates.lua I have the below that works fine:

Code: Select all

-- Adds a resitance of all damage types to an entity
for k, v in pairs(data.raw["damage-type"]) do
	local Resist = {type = v.name, percent = 70} -- or you could use k, and not v.name		
	
				if data.raw.inserter["combat-inserter"].resistances == nil then 
					data.raw.inserter["combat-inserter"].resistances = {}
					table.insert(data.raw.inserter["combat-inserter"].resistances, Resist)
				else
				local found = false
				for _, resistance in pairs(data.raw.inserter["combat-inserter"].resistances) do
					if resistance.type == Resist.type and resistance.percent then
						if resistance.percent < Resist.percent then
							resistance.percent = Resist.percent
						end
						found = true
					end            
				
					if not found then
						table.insert(data.raw.inserter["combat-inserter"].resistances, Resist)
					end
				end
			end

	
end

Fixed it up - there was a small error in the code that gave silly results.
Attached fixed versions.

Thanks Orzelek,
I'm out on vacation the next 4 days, but will check it out when I get back.

EDIT: Works like a charm! Thanks Orzelek!
