Splash Damage 2.0 script (make explosions better!)

[Grimm]

Hi guys, I've forked wheelyjoe's Splash Damage script and added some features you might find interesting:

 

-Adds a blast wave effect which adds timed and scaled secondary explosions on top of game objects

-Object geometry within blast wave changes damage intensity

-Additional damage boost for structures since they are hard to kill, even if very close to large explosions.

-Damage model for ground units that will disable their weapons and ability to move with partial damage before they are killed.

 

 

INSTALLATION:

Load at mission start in mission editor using Trigger> 4 Mission Start > Do Script File (script file)

 

Please let me know what you think!  If a weapon is missing from the script, it will display a message to let you know.  If you can get the name of the weapon to me (or your DCS.log file), I can get it added in.

Hello and thank you for the script.

I am trying it out for my missions and I was wondering if there is anyway to stop it from displaying the messages?

 

I have tried changing the following line to false:  ["game_messages"] = false, --enable some messages on screen,

however it is still displaying the messages.

 

Thanks in advance

@Swampy Thanks for trying the script!  Would you be able to send me your DCS.log file?  It should only be showing messages about missing weapons with game_messages set to false, and I'd really like it to be complete.  

However I added the option to disable those messages in the latest update.  Download the file again from the first post and set ["weapon_missing_message"] = false

@Grimm

I Downloaded the file again and it doesn't appear to be showing the messages.

 

Thanks again

AT_6 missing from Splash Damage script

[Magnum]

I found this script interesting and have been working on adding weapons to the table for WW2 aircraft. Its also a bit spammy for flak in the dcs.log because it's tracking the shot event. I'm not quite sure what the value is for each variable(maybe a damage modifier?) but here is what i've added so far to the table; 

  ["British_GP_250LB_Bomb_Mk1"] = 100,           --("250 lb GP Mk.I")
  ["British_GP_250LB_Bomb_Mk4"] = 100,           --("250 lb GP Mk.IV")

These seem to be flak and vehicles and it may be helpful to exclude these from the tracked events...

Should be the equivalent explosion power in kilograms of TNT (maybe RDX?) per detonation event.

I think there is some uncertainty about what explosive, exactly, is used to specify this number, in part because it seems like the definition of 1 unit seems a bit off (based on people trying to reverse engineer the effects in the game engine, and the possibility that the devs are adjusting the definition slightly).

[Wheelyjoe]

Hey, nice work mate.

I originally had the secondary explosions on units as well, but I thought it looked a bit janky, and the existing system for explosions is okay, the values used are just terrible. I did some rudimentary testing and compared to "real world" numbers (I used to study at the UK's blast injury research centre), and it was close enough for something running as a script IMO. I'd much rather it be fixed by ED than me

I also used to have it "suppress" units when they were caught within a certain radius, but as disabling AI and weapons is only doable on a per group level it can make a unit quite some distance away "stunned" and it felt a little cheesy.

Totally okay with you adding these features back, just thought I'd note what I'd done and discounted and why. That and performance, trying to eek every single frame out of DCS, haha!

Enjoy the script, check out the IADS one too if you're into a bit more realism! Needs an update for new launchers, but it's still a fun addition to a server and really easy to use!

@Grimm

is this correct? it looks the wrong way round (inverted?)

["weapon_missing_message"] = false, --false disables messages alerting you to weapons missing from the explTable

 

        if splash_damage_options.weapon_missing_message == false then
          trigger.action.outText(ordnance:getTypeName().." missing from Splash Damage script", 10)
        end

@Grimm

Thanks for the fascinating script! I am trying this script too.

I wanted to hide the message, so I set the options as follows.

Quote

["game_messages"] = false
["weapon_missing_message"] = false

However, even with this setting, the weapon_missing_message did not disappear. So I looked at the part about displaying the weapon_missing_message, and found this on line 239.

Quote

if splash_damage_options.weapon_missing_message == false then

When I set this part to true, the weapon_missing_message is displayed or not displayed as per the option setting.

I hope you will check it out.

As a Japanese, English is difficult for me.

[Grimm]

@Magnum This is huge!  Thank you!  All ready to copy and paste and everything! I've added these to the script, and implemented a filter for anything that has "weapons.shells"

@Wheelyjoe  Thanks for the comments, helpful info, and the clever scripting!!!  

All, attached is latest dev version of the script with the changes above and the "weapon_missing_message" issue fixed.

[JeffreyC]

Love your splash damage! Thank you so much for making this!!

[IAF.AssafB]

Hello and thanks for sharing!
I wonder if this script can be used to include artillery shells as well.

What I have in mind is to be able to use artillery for suppression of SAM sites if hitting anywhere around them (Not even causing actual damage but to mimic SAM crews being shocked and unable to function for a minute or two....stuff like that).

Specifically looking at 155mm arty (PALADIN and MSTA) as well as 120mm mortar rounds.

 

With scripting knowledge which is next to nil I'd sure appreciate your experts' opinions

Thanks !

Hmm in this version? I have that and still get the text showing up.

Yes the file attached should be the most recent.  It is the develop branch if you are pulling it from the repo.  Also make sure you remove the script and re-add to your mission when updating.  Let me know if it's still an issue.

Was my bad, did not re-added the script, just change the file in its location.

Now it works, no more text. Thank you!

Heya! I love your script, but unfortunately I found that it interferes with MOOSE scoring. Ground target hits are no longer detected by MOOSE (latest stable version). Is this a known issue  or did I just miss a step?

Argh, I don't think I have that log anymore. But I did scour through it and saw no error or other related message really. I think what happens is that MOOSE hooks into the events, and then you hook into the events, and apparently events handlers work via the highlander-principle. But I could be wrong!

[Mistermann]

Very cool.  I am reminded of the video footage from the latest Apache update.  That splash damage from the 30mm chain gun is on full display.

Got some logs for you!

Unfortunately, there's not much to see: https://pastebin.com/casfvtuj

For this test, I load up the Splash Damage script before MOOSE. However, that doesn't change a thing.

The units I attacked are inside a zone, and are spawned as follows:

 

function CaucasusPendulum.SpawnCaptureZoneUnits (zoneName, coalitionParam)
	local SpawnZones = { ZONE:FindByName( zoneName .. " ZONE" )}
	local coalitionName = "BLUE"
	if (coalitionParam == coalition.side.RED) then
		coalitionName = "RED"
	end
	local SpawnGroup 

	env.info("GROUP SPAWN: "..coalitionName.." "..zoneName)

    SpawnGroup = SPAWN
		:New(coalitionName .. " " .. zoneName .. " GROUP")
		:InitKeepUnitNames( true )
		:InitLimit(20,0)
	SpawnGroup:Spawn()
end

 

So really nothing special. The zone has MOOSE scoring set up as follows:

 

Score = SCORING:New( "Caucasus Pendulum" )
Score:SetScaleDestroyScore( 100 )
Score:SetScaleDestroyPenalty( 200 )
Score:SetMessage<profanity>( false )
Score:SetMessagesDestroy( true )
Score:SetMessagesToAll( true )
Score:AddZoneScore(AlphaZone, 50)

 

The result is that neither the scoring messages, nor any actual score updates seem to work once SplashDamage is loaded together with MOOSE.

EDIT: Here's how MOOSE hooks in:

  self:HandleEvent( EVENTS.Dead, self._EventOnDeadOrCrash )
  self:HandleEvent( EVENTS.Crash, self._EventOnDeadOrCrash )
  self:HandleEvent( EVENTS.Hit, self._EventOnHit )

It seems like these don't work anymore once SplashDamage is loaded. Maybe the event has to be passed on by you so other handlers can receive it as well?

EDIT: I tried replacing the pcall with a direct call in the splashdamage event handler:

function WpnHandler:onEvent(event)
--  protectedCall(onWpnEvent, event)
	onWpnEvent(event)
end

However that changed nothing - splash damage works fine still, but no MOOSE scoring events.

EDIT2: Also tried disabling wave_explosions, same result.

[Kervinou]

Big thanks for your work.

We R lot of virtual pilot to use and appreciate it

[Toumal]

I've been thinking about the MOOSE scoring problem and I *think* I might have an idea why it happens:

What if it's not really about the event handling hooks at all? What if the problem is actually the way nearby units are being damaged by the script? After all, you're spawning an explosion for units in the blast radius like so:

trigger.action.explosion

I believe this may be why MOOSE cannot pick this up and determine who did it. Sooooooooo I think what I'll do is make a function that lets me pass on the player to the MOOSE damage code. I don't really need the player unit or the weapon for scoring.

EDIT: Confirmed that this is indeed the root cause of the issue. Working on a fix, but I have one problem that I posted another thread for.
