Understanding ME : objects life point

[CougarFFW04]

Hi everyone,

 

I would like to know if :

 

- it's possible to find elsewhere the "point of life" associated to any DCS object (for exemple what is life point associated to a TV antenna or whatever) ?

 

- it's possible to change the point of life associated to static object we put somewhere inthe DCS world (for exemple I want that the point of life of a flag I put elsewhere is 5000) ?

 

- or even better, is is possible to add our own object with our associated life point ?

 

Thanks

You can either use the scripting function Unit.getLife0() or read the life table entry from Object.getDesc(). I periodically export the getDesc table for all objects to github, so you can reference the list that way.

 

No, can't modify the life values via scripting. You'd have to find hte DB entry in the install/Scripts/Database folder to change the life values.

 

Yes, setting how much life the object has is part of creating a mod like that. Unsure if it is a required table entry, but I'd guess that most if not all mods that add objects set that value to something.

Hi there Grimes!

 

I've been trying to make :getLife0() work with static objects (to help CougarFFW04), but it keeps generating the following scripting error:

attempt to call method 'getLife0' (a nil value)

 

However, :getLife() works like a charm.

 

Here's my test script:

 

local StaticSet = SET_STATIC:New()

:FilterPrefixes("Static_") -- All relevant statics in ME must use this prefix!

:FilterStart()

 

StaticSet:ForEachStatic(

function(StaticSet)

 

local StaticDCSObjectCategory = StaticSet:GetCategory()

 

if StaticDCSObjectCategory ~= nil --This is required in order to avoid scripting errors generated by some unsupported static objects in the set (ie. the new Sea Shelf Objects)

then

 

local StaticDCSObject = StaticSet:GetDCSObject()

local StaticIdentifiableName = StaticSet:GetName()

local StaticObjectInitialLife = StaticDCSObject:getLife0() -- Generates the scripting error I mentioned earlier. If I comment this line out, the script works

local StaticObjectCurrentLife = StaticDCSObject:getLife()

 

MESSAGE:New(StaticIdentifiableName.." initial life = "..StaticObjectInitialLife,10):ToAll() -- This line needs to be commented out as well for the script to work, obviously

MESSAGE:New(StaticIdentifiableName.." current life = "..StaticObjectCurrentLife,10):ToAll()

end

end

)

 

 

After struggling with this for hours, I went back to your wiki and noticed something that might explain this behaviour.

According to the documentation, :getLife0() isn't available for classes other than Unit (so it can't be used with Static Object or Scenery Object classes).

 

On the other hand, :getLife() seems to be available for Unit, Static Object and Static Scenery classes (that's probably why it works with the statics in my test mission).

 

Can you confirm this? (Or just explain what might be going on)

 

 

Thanks and happy new year! :thumbup:

If you're interested, I've modified my test mission from the other thread (yet again) in order to obtain the "life status" of all static objects (except for the two Sea Shelf Objects, which aren't supported).

 

I'm attaching the two modified versions here.

 

The first version will provide the raw numeric life value for each static object when it gets hit (as well as the rest of data you requested in the other thread).

NOTE: You'll get spammed with status messages as bombs hit several static objects simultaneously...sorry about that

 

Here's the script it uses:

 

local RedSet = SET_GROUP:New()

:FilterPrefixes("Red_") -- All relevant attack groups in ME must use this prefix!

:FilterStart()

 

local StaticSet = SET_STATIC:New()

:FilterPrefixes("Static_") -- All relevant statics in ME must use this prefix!

:FilterStart()

 

 

RedSet:HandleEvent(EVENTS.Hit)

 

function RedSet:OnEventHit(EventData)

 

local TargetCategory = EventData.TgtObjectCategory

 

Attacker = EventData.IniUnitName

 

if TargetCategory == 3 or TargetCategory == 6

then

 

local TargetName = EventData.TgtUnitName

local TargetObjectCurrentLife = EventData.TgtDCSUnit:getLife()

local TargetCoalition = EventData.TgtCoalition

 

if TargetCoalition == 1

then

MESSAGE:New(TargetName.." (Red coalition) has been hit by "..Attacker.."\nRemaining life --> "..TargetObjectCurrentLife,10):ToAll()

 

elseif TargetCoalition == 2

then

MESSAGE:New(TargetName.." (Blue coalition) has been hit by "..Attacker.."\nRemaining life --> "..TargetObjectCurrentLife,10):ToAll()

end

 

elseif TargetCategory == 0

then

MESSAGE:New("Sea shelf object has been hit by "..Attacker,10):ToAll()

end

end

 

 

StaticSet:HandleEvent(EVENTS.Dead)

 

function StaticSet:OnEventDead(EventData)

 

local DeadStatic = EventData.IniUnitName -- This doesn't work for Sea Shelf Objects

local DeadStaticCategory = EventData.IniObjectCategory -- 3 = Ground Vehicle/Plane/Helicopter/Structure , 5 = Airport structure, 6 = Cargo, 0 = Sea Shelf Object

local DeadStaticCoalition = EventData.IniCoalition -- 1 = Red , 2 = Blue (This doesn't work for Sea Shelf Objects either!)

 

if DeadStaticCategory == 3 or DeadStaticCategory == 6

then

if DeadStaticCoalition == 1

then

MESSAGE:New(">>> "..DeadStatic.." (Red coalition) has been destroyed by "..Attacker.." <<<",10):ToAll()

 

elseif DeadStaticCoalition == 2

then

MESSAGE:New(">>> "..DeadStatic.." (Blue coalition) has been destroyed by "..Attacker.." <<<",10):ToAll()

end

 

elseif DeadStaticCategory == 0

then

MESSAGE:New(">>> Sea shelf object destroyed by "..Attacker.." <<<",10):ToAll()

end

end

 

 

The second version will provide the raw life numerical value for each static object at mission start, then you'll get their individual life values in percentages, as they get hit (as well as the rest of stuff you requested in the other thread).

NOTE: You'll get spammed with status messages as bombs hit several static objects simultaneously...sorry about that

 

Here's the ugly script it runs on (I had to do it this way because I couldn't make :getLife0() work with the static objects):

 

 

local RedSet = SET_GROUP:New()

:FilterPrefixes("Red_") -- All relevant attack groups in ME must use this prefix!

:FilterStart()

 

local StaticSet = SET_STATIC:New()

:FilterPrefixes("Static_") -- All relevant statics in ME must use this prefix!

:FilterStart()

 

 

StaticSet:ForEachStatic(

function(StaticSet)

 

local StaticDCSObjectCategory = StaticSet:GetCategory()

 

if StaticDCSObjectCategory == 3 or StaticDCSObjectCategory == 6

then

 

local StaticDCSObject = StaticSet:GetDCSObject()

local StaticIdentifiableName = StaticSet:GetName()

local StaticObjectCurrentLife = StaticDCSObject:getLife()

 

MESSAGE:New(StaticIdentifiableName.." initial life = "..StaticObjectCurrentLife,10):ToAll()

end

end

)

 

 

RedSet:HandleEvent(EVENTS.Hit)

 

function RedSet:OnEventHit(EventData)

 

local TargetCategory = EventData.TgtObjectCategory

 

Attacker = EventData.IniUnitName

 

if TargetCategory == 3 or TargetCategory == 6

then

 

local TargetName = EventData.TgtUnitName

local TargetObjectCurrentLife = EventData.TgtDCSUnit:getLife()

local TargetCoalition = EventData.TgtCoalition

 

--The following are custom life percentage calculations for (almost) each static object (the only thing that changes is their initial life value)

Hi Guys,

 

@Grime: Thanks for your prompt reply. I will have a look at the list.

 

@Hardcard: Thanks. Already got things in the other thread but got these ones as well. This helped a lot.

 

This community rocks :smartass::thumbup::pilotfly:

[Grimes]

getLife0() was added after they changed how getLife() worked. Likely they just forgot to add it to static and scenery objects. Can always fall back on using getDesc().life to get initial life value.

 

The sea shelf objects suffer from the same bug as a FARP where the object fails to return, I should probably update that bug report since its been around for a while.

[Hardcard]

@Grimes

 

Thanks for the explanation and for the getDesc().life, it'll come in handy!

 

Unfortunately, I've noticed some discrepancies in the returned life values of certain statics.

 

 

 

I've attached my test mission, here's the script it runs on (no errors in dcs.log):

 

SCHEDULER:New( nil,

function()

 

local StaticSet = SET_STATIC:New()

:FilterPrefixes("Static_") -- All relevant statics in ME must use this prefix!

:FilterStart()

 

StaticSet:ForEachStatic(

function(StaticSet)

 

local StaticDCSObjectCategory = StaticSet:GetCategory()

 

if StaticDCSObjectCategory ~= nil

then

 

local StaticDCSObject = StaticSet:GetDCSObject()

local StaticIdentifiableName = StaticSet:GetName()

local StaticObjectInitialLife = StaticDCSObject:getDesc().life

local StaticObjectCurrentLife = StaticDCSObject:getLife()

 

MESSAGE:New(StaticIdentifiableName.." getDesc().life reading = "..StaticObjectInitialLife.."\n"..StaticIdentifiableName.." getLife() reading = "..StaticObjectCurrentLife,10):ToAll()

end

end

)

end, {}, 1, 10

)

 

 

Is the description table out of date?

 

It's a real pity, this is really useful stuff :cry:

I know this is an old thread but would you help me export the life status of objects via export.lua?
