Dummy question about mod

[overmouse]

Hello.

Does any1 can give me a simple script like MiniTools 1.2 with another functions?

Actually i need to understand how to make a lightning strike right into my character (with damage and etc.)

and how to spawn any creature in random position around character by keypress

I'm dumb in LUA, spent about 2 hours trying to combine minitools and some LUA text from DS, but get success only in sound and visual effects around, but can not get lightning strike to hit player.

 

[whismerhill]

take a look at "books.lua" in particular "firefn" function it's the function that create lightning strikes for the appropriate book of wickerbottom

[overmouse]

Thanks for answer!

 

Okay. i taking function  firefn from books.lua, copy-paste it in to commands.Lua in MiniTools, assign an a hotkey, remove sanity debuff(i don't need it) and...

got an errors on "reader" part of function when i trying to call it in game. 

So i guess "reader" it's a some active class or action or something, while player clicking on book and calling reader.lua

Okay. goin next. Remove "reader." part because we don't reading any book, just trying to call function by key.

And i still haven't success:

function firefn(inst)

    local num_lightnings =  16
  
    
        for k = 0, num_lightnings do

            local rad = math.random(3, 15)
            local angle = k*((4*PI)/num_lightnings)
            local pos = Vector3(Transform:GetWorldPosition()) + Vector3(rad*math.cos(angle), 0, rad*math.sin(angle))
            GetSeasonManager():DoLightningStrike(pos)
            Sleep(math.random( .3, .5))
        end
    end

Got an error here:
 

calling 'GetWorldPosition' on bad self (Transform expected, got table)

 

[whismerhill]

wow wow wow xD

ok first thing first, rename that function, it's kinda bad practice to keep the same name for a function which is supposed to do something else. It's not supposed to cause issues I believe but still.

2nd unless you wanna reuse that function in yet another mod, it should be kept local so add "local " before "function"

3rd you removed the "reader" entity from transform:getworldposition() which means you're basically asking it to get the world position of nothing ? since now there is no "self" entity anymore

if inst (the passed argument) is your character, then I believe it should be

inst.Transform:GetWorldPosition()

if not then you need to get the player from global

local player = GLOBAL.GetPlayer()

and pass "player" instead of "inst"

 

Also you do realize that function will create 16 lightning strikes at random around your character ? hope that's what you want, or you'll need to modify it further xD

[overmouse]

thanks for keep answering... I'm very appreciate for it.

Okay i will rename it for something like to me. It's not a prob, i understand that i should rename it in 2 files.

So okay. Now i understand - "inst" it's a random 4 letters like "abcd", is using to keep something in memory... 

Used 

local inst = GetPlayer() 

(Global.GetPlayer makes game crash for "Global" part, dunno why)

So code looks like this now:

CodeImage  (don't know why i can't paste a code of it here, forum blocking it)

And now i passed all syntax errors and it... Still not works:

(don't know how i should copy-paste errors from this)

 

So i see that we have error for "sleep" function. I don't need it. Removing.

And it works! Got some strikes around my character. Finally a little succes from me, with your patience and help, @whismerhill!

So now i will try to close radius of striking to 0 and i will get hits in to my character:

Deleted

Vector3(rad*math.cos(angle), 0, rad*math.sin(angle))

Because it's making a big circle around Player position and...

I see lightning strike now, i hear it, but it makes 0 damage to my Character, looks like Strike hits in a front of him. Checked it - moved character behind a tree, and yes - Strike hits tree, not character. 

What i did wrong again?

[whismerhill]

it should be GLOBAL not Global it's case sensitive as far as I know.

otherwise I don't really know why your character is not hit by the lightning strike. You seem on the right track

Edited June 8, 2016 by whismerhill

[overmouse]

With GLOBAL it's still make error. 

Variable 'GLOBAL' is not declared. 

Think it's not much important.

 

I guess i don't get hit by lighning because i taked function from SpellBook, it's not organized to hit player. So i need to understand how the lightning hitting player when weather goes rainy...

 

Edited June 8, 2016 by overmouse

[overmouse]

So. We have playerlightningtarget.lua 

He explains how player can get be hitted by strike.

But can i modify it and call strike with these parameters? 

Didn't thought that LUA will be so... strange and hard.

[whismerhill]

you could indeed try to add the wx78 component that makes him a lightning target with something like :

GetPlayer():AddComponent("playerlightningtarget")

before the lightning strike

[overmouse]

Not works. Nil Value

Looked for seasonmanagers in other places - they haven't "CanBeHit" method, but i don't understand how to call them to avoid this error...

[whismerhill]

you're not on DST right ?

[overmouse]

No ofc, I need it for DS ShipWrecked for example.

Edited June 9, 2016 by overmouse

[whismerhill]

I don't have any more ideas, don't even understand why GLOBAL.GetPlayer() doesn't work in your mod. Strange stuff

among the wall of text, this explains why GLOBAL.GetPlayer & not GetPlayer :

 

[overmouse]

Doh... does any1 in forum make scripts for payment? I can make a donation for it, we spend too much time in discussion this... 

[overmouse]

Em... i don't know what happends.

function shootme()

  local num_lightnings =  1
  local inst = GetPlayer() 
    
        for k = 0, num_lightnings do

            local rad = math.random(3, 15)
            local angle = k*((4*PI)/num_lightnings)
            local pos = Vector3(inst.Transform:GetWorldPosition()) + Vector3(rad*math.cos(angle), 0, rad*math.sin(angle))
			GetPlayer():AddComponent("playerlightningtarget")
            GetSeasonManager():DoLightningStrike(pos)
            GetClock():DoLightningLighting(.5)
			
        end
    end

Works.

[overmouse]

Upd:

removed 

GetClock():DoLightningLighting(.5)

Still works.

Removed radius of lightning - still works:

function shootme()

  local num_lightnings =  10
  local inst = GetPlayer() 
    
        for k = 1, num_lightnings do

            
            local pos = Vector3(inst.Transform:GetWorldPosition())
			GetPlayer():AddComponent("playerlightningtarget")
            GetSeasonManager():DoLightningStrike(pos)
           
			
 end
   end

So sometimes it hits player, sometimes hit in front of player.

It's located in local pos = Vector3(inst.Transform:GetWorldPosition())

So radius a bit higher than character's coords. Can i make radius a bit lower?

And game takes parameters of lightning rod, if it near - player didn't get hits.. Any idea how to solve it?

Edited June 9, 2016 by overmouse

[whismerhill]

you should have understood how to work stuff out by now

watch getseasonmanager():dolightningstrike() function (in seasonmanager.lua)

I believe I saw a paramater exactly for this if I'm not mistaken

[overmouse]

Ye, i get some knowledge, you helps a lot in it, but i'm stull dumbed xD

 

I saw in seasonmanager these options. Rod and chance of hit.

I dn't understand how i may change these for few moments like:

buttonpressed - script takes values of modified parameters from script folder, then make hit, then return parameters like it was in game.

(i mean i don't want to change game files)

So i should make personal .lua file with these parameters and load it on buttonpressed otherwise of seasonmanagers options... 

next level of Lua scripting.

[overmouse]

 

So okay. 

I taked TwitchPlays mod as example and saw, that they in modmain.lua do this:

 

local require = GLOBAL.require
local TwitchPlaysButton = require("widgets/twitchplaysbutton")

They call modified files with these text.

So i did the same with playerlightningtarget.lua with another name. Tryed to modify it, but still no reaction with hitChance.

Going next:

Taked SeasonManager_sw.lua, renamed it into SeasonForStrike, croped a lot of stuff from it(which works on seasons, autumn, tornado etc). Renamed a lightningningstrike function into DoLightningStrikeHitMe

Now i have these: 

ModMain.lua

local require = GLOBAL.require
local PlayerTargetStrike = require("components/PlayerTargetStrike")
local SeasonForStrike = require("components/SeasonForStrike")

Commands.lua

function shootme()
  local num_lightnings =  1
  local inst = GetPlayer() 
       for k = 1, num_lightnings do
            local pos = Vector3(inst.Transform:GetWorldPosition())
			GetPlayer():AddComponent("PlayerTargetStrike")
            GetSeasonForStrike():DoLightningStrikeHitMe(pos)
end
end

I put PlayerTargetStrike.lua and SeasonFroStrike.lua into components folder.

But now it makes an error for me:

Variable 'GetSeasonForStrike is not declared.

Why in previous post these works perfectly?

GetSeasonManager():DoLightningStrike(pos)

Can i find workaround in this way?

Edited June 9, 2016 by overmouse

[whismerhill]

I have trouble understanding what you're saying

what I was pointing at however is that there's an additional parameter for the function " getseasonmanager():dolightningstrike() "

as long as you're in the RoG folder the function is declared like this: (I can't check about SW, check it out if you're gonna use that)

function SeasonManager:DoLightningStrike(pos, ignoreRods)
    local rod = nil
    local player = nil
	if not ignoreRods then

which means when calling it you can write it as such

GetSeasonManager():DoLightningStrike(pos, true)

and it should ignore rods

no need to rewrite functions or any nonsense like this imho

[overmouse]

Okay.

But in playerlightningtarget it declares some protection from items when strike can hit

local DefaultOnStrike = function(inst)
    if inst.components.health and not inst.components.health:IsDead() then
        local protected = false
        if GetPlayer().components.inventory:IsInsulated() then
            protected = true
        end

        if not protected then
            local mult = TUNING.ELECTRIC_WET_DAMAGE_MULT * inst.components.moisture:GetMoisturePercent()
            local damage = -(TUNING.LIGHTNING_DAMAGE + (mult * TUNING.LIGHTNING_DAMAGE))
            -- Magic hit point stuff that isn't being used right now
            -- if damage >= inst.components.health.currenthealth - 5 and inst.components.health.currenthealth > 10 then
            --     damage = inst.components.health.currenthealth - 5
            -- end

            inst.components.health:DoDelta(damage, false, "lightning")
            inst.sg:GoToState("electrocute")
        else
            inst:PushEvent("lightningdamageavoided")
        end
    end
end

Also declared hit chance:

local PlayerLightningTarget = Class(function(self, inst)
    self.inst = inst
    self.hitchance = 0.3
    self.onstrikefn = DefaultOnStrike
end)

I need to ignore all varietes when strike can't hit player.

For example now: you show me how to ignore rods, but it still not hitting me when player get SnakeSkin Hat, or SnakeSkin Jacket or something else what can protect in SW from strike.

 

That's why i wanted to make my personal .LUA files in script directory, to load all these settings, overwrite it in memory of game when we press button to strike(ignoring rods and all stuff that make immune to hit), and after strike leave it for default settings.

[overmouse]

So no idea what to do? :/

[Arkathorn]

--This variable is the class definition for the season manager
local SeasonManager = require "components/seasonmanager"

--Register a new function to do a lightning strike ignoring all distractions
--Use the target argument to make things easier; this is the thing that will be hit
function SeasonManager:DoImmutableLightningStrike(pos,target)
	local lightning = SpawnPrefab("lightning")
	lightning.Transform:SetPosition(pos:Get())

	if target then
		pos = Vector3(target.Transform:GetWorldPosition())
	end

	if target then
		if target.components.playerlightningtarget then
			target.components.playerlightningtarget:DoStrike()
		else
			target:PushEvent("lightningstrike", {rod=target})
		end
	else
		local ents = TheSim:FindEntities(pos.x, pos.y, pos.z, 3, nil, {"FX", "NOCLICK", "DECOR", "INLIMBO"})
		for k,v in pairs(ents) do 
			if not v:IsInLimbo() then
				if v.components.burnable and not v.components.fueled and not v.components.burnable.lightningimmune then
					v.components.burnable:Ignite()
				end
			end
		end
	end
end

This code defines a function that does an immutable lightning strike (ignores lightning rods and hit chance).

Call the function like so:

--To call the function on a location, provide it with a Vector3: (These are arbitrary coordinates, they could be anything)
GetSeasonManager():DoImmutableLightningStrike(Vector3(5,0,-27))

--To call the function on a target, provide it with a nil value, followed by the target's instance
GetSeasonManager():DoImmutableLightningStrike(nil, GetPlayer())

 

[overmouse]

Another way to realise lightning strike with ignoring rods

Thanks @Arkathorn 

But character still immune while wearing SnakeSkin Hat and Jacket :/

Combined playerlightningtarget

local inst=GetPlayer()
local mult = TUNING.ELECTRIC_WET_DAMAGE_MULT * inst.components.moisture:GetMoisturePercent()
local damage = -(TUNING.LIGHTNING_DAMAGE + (mult * TUNING.LIGHTNING_DAMAGE))
inst.components.health:DoDelta(damage, false, "lightning")
inst.sg:GoToState("electrocute")
		

- so it makes 

function SeasonManager:DoImmutableLightningStrike(pos,target,inst)
	local inst=GetPlayer()
	local lightning = SpawnPrefab("lightning")
	pos = Vector3(target.Transform:GetWorldPosition())
	lightning.Transform:SetPosition(pos:Get())

	if target then
		if target.components.playerlightningtarget then
		    local mult = TUNING.ELECTRIC_WET_DAMAGE_MULT * inst.components.moisture:GetMoisturePercent()
            local damage = -(TUNING.LIGHTNING_DAMAGE + (mult * TUNING.LIGHTNING_DAMAGE))
            inst.components.health:DoDelta(damage, false, "lightning")
            inst.sg:GoToState("electrocute")
			target.components.playerlightningtarget:DoStrike()
		else
			target:PushEvent("lightningstrike", {rod=target})
		end
	else
		local ents = TheSim:FindEntities(pos.x, pos.y, pos.z, 3, nil, {"FX", "NOCLICK", "DECOR", "INLIMBO"})
		for k,v in pairs(ents) do 
			if not v:IsInLimbo() then
				if v.components.burnable and not v.components.fueled and not v.components.burnable.lightningimmune then
					v.components.burnable:Ignite()
				end
			end
		end
	end
end

Now it hits me and ignoring SnakeCloth.

But game thinks, that player still immune - and after hit he says the immune phrase. 

That's not serious problem anyway.

 

Thanks guys! You help a lot!
