I'm apparently trying to do the same thing... or something quite similar. See /viewtopic.php?f=53&t=15788

Could you be so kind to link or paste the code in which you got the beetles to go nuclear?

Took me a bit of fiddling, but finally got it working! There were a lot of little things that had to be fixed, and I continuously interpreted the error messages poorly! Thanks for your help Exotic. New unit added to my mod thread :p

Code:: OnFire = function(self) self:Fire() KamikazeWeapon.OnFire() end,

i meant something like this.

atm it wont fire ofc since nothing is calling it xD
Onfire is a callback that is called.... on fire xD
Fire is just a function that is SOMETIMES called if a script asks for it. only place i know of that happening is the death thread, which has to do it like this since weapons are cleared by that point.

you should also rename the Fire function to something else, or just put the function inside Onfire instead.

@Tokyto; no worries;

Code:: local DeathNukeWeapon = import('/lua/sim/defaultweapons.lua').DeathNukeWeapon

@Exotic; So spoilers for my mod thread lol
Do you mean like this? This is in my hooked terranweapons.lua file;

Code:: local KamikazeWeapon = WeaponFile.KamikazeWeapon DeployableNuke = Class(KamikazeWeapon){ OnFire = function(self) end, Fire = function(self) local bp = self:GetBlueprint() local proj = self.unit:CreateProjectile(bp.ProjectileId, 0, 0, 0, nil, nil, nil):SetCollision(false) proj:ForkThread(proj.EffectThread) -- Play the explosion sound local projBp = proj:GetBlueprint() if projBp.Audio.NukeExplosion then self:PlaySound(projBp.Audio.NukeExplosion) end proj.InnerRing = NukeDamage() proj.InnerRing:OnCreate(bp.NukeInnerRingDamage, bp.NukeInnerRingRadius, bp.NukeInnerRingTicks, bp.NukeInnerRingTotalTime) proj.OuterRing = NukeDamage() proj.OuterRing:OnCreate(bp.NukeOuterRingDamage, bp.NukeOuterRingRadius, bp.NukeOuterRingTicks, bp.NukeOuterRingTotalTime) local launcher = self.unit local pos = proj:GetPosition() local army = launcher:GetArmy() local brain = launcher:GetAIBrain() local damageType = bp.DamageType proj.InnerRing:DoNukeDamage(launcher, pos, brain, army, damageType) proj.OuterRing:DoNukeDamage(launcher, pos, brain, army, damageType) -- Stop it calling DoDamage any time in the future. proj.DoDamage = function(self, instigator, DamageData, targetEntity) end end, }

(Accidentally hit submit): The detonation command doesn't do anything but no errors are produced, except when i Control-K and I get:
WARNING: Error running lua script: ...ata\faforever\gamedata\lua.nx2\lua\terranweapons.lua(274): attempt to call method `GetBlueprint' (a nil value)

Re: Nuke "Fire Beetle"

so you simply copy that code from either the nuke projectile and put it into onfire instead
or you copy it from the deathnuke and also put it into onfire

then you just get the beetle to fire its weapon. which should be default.
what we are doing here is simply transferring the code from the projectile to the units weapon, so here it will go off as soon as its fired and not when it hits sth

probably easier to copy from the deathnuke since its more related to the unit and would need to be tweaked less.

Sorry to flood your thread :S But any idea what was this renamed to?

local CIFCommanderDeathWeapon = CWeapons.CIFCommanderDeathWeapon

@Tokyto; Your mod probably doesn't work because FAF moved the commander death weapon to defaultweapons.lua instead of the respective faction weapon files.

@Exotic; the code I pasted is from defaultweapons.lua
If I follow say UEB2305 (uef sml):
UEB2305_unit.bp

Code:: ProjectileId = '/projectiles/TIFMissileNuke01/TIFMissileNuke01_proj.bp',

TIFMissileNuke01_script.lua

Code:: # # Terran Nuke Missile # local TIFMissileNuke = import('/lua/terranprojectiles.lua').TIFMissileNuke TIFMissileNuke01 = Class(TIFMissileNuke) { InitialEffects = {'/effects/emitters/nuke_munition_launch_trail_02_emit.bp',}, LaunchEffects = { '/effects/emitters/nuke_munition_launch_trail_03_emit.bp', '/effects/emitters/nuke_munition_launch_trail_05_emit.bp', '/effects/emitters/nuke_munition_launch_trail_07_emit.bp', }, ThrustEffects = {'/effects/emitters/nuke_munition_launch_trail_04_emit.bp', '/effects/emitters/nuke_munition_launch_trail_06_emit.bp', }, OnImpact = function(self, TargetType, TargetEntity) if not TargetEntity or not EntityCategoryContains(categories.PROJECTILE, TargetEntity) then # Play the explosion sound local myBlueprint = self:GetBlueprint() if myBlueprint.Audio.Explosion then self:PlaySound(myBlueprint.Audio.Explosion) end nukeProjectile = self:CreateProjectile('/effects/Entities/UEFNukeEffectController01/UEFNukeEffectController01_proj.bp', 0, 0, 0, nil, nil, nil):SetCollision(false) nukeProjectile:PassDamageData(self.DamageData) nukeProjectile:PassData(self.Data) end TIFMissileNuke.OnImpact(self, TargetType, TargetEntity) end, DoTakeDamage = function(self, instigator, amount, vector, damageType) if self.ProjectileDamaged then for k,v in self.ProjectileDamaged do v(self) end end TIFMissileNuke.DoTakeDamage(self, instigator, amount, vector, damageType) end, OnCreate = function(self) TIFMissileNuke.OnCreate(self) local launcher = self:GetLauncher() if launcher and not launcher:IsDead() and launcher.EventCallbacks.ProjectileDamaged then self.ProjectileDamaged = {} for k,v in launcher.EventCallbacks.ProjectileDamaged do table.insert( self.ProjectileDamaged, v ) end end self:SetCollisionShape('Sphere', 0, 0, 0, 2.0) self:ForkThread( self.MovementThread ) end, CreateEffects = function( self, EffectTable, army, scale) for k, v in EffectTable do self.Trash:Add(CreateAttachedEmitter(self, -1, army, v):ScaleEmitter(scale)) end end, MovementThread = function(self) local army = self:GetArmy() local launcher = self:GetLauncher() self.CreateEffects( self, self.InitialEffects, army, 1 ) self:TrackTarget(false) WaitSeconds(2.5) # Height self:SetCollision(true) self.CreateEffects( self, self.LaunchEffects, army, 1 ) WaitSeconds(2.5) self.CreateEffects( self, self.ThrustEffects, army, 3 ) WaitSeconds(2.5) self:TrackTarget(true) # Turn ~90 degrees towards target self:SetDestroyOnWater(true) self:SetTurnRate(47.36) WaitSeconds(2) # Now set turn rate to zero so nuke flies straight self:SetTurnRate(0) self:SetAcceleration(0.001) self.WaitTime = 0.5 while not self:BeenDestroyed() do self:SetTurnRateByDist() WaitSeconds(self.WaitTime) end end, SetTurnRateByDist = function(self) local dist = self:GetDistanceToTarget() #Get the nuke as close to 90 deg as possible if dist > 150 then #Freeze the turn rate as to prevent steep angles at long distance targets self:SetTurnRate(0) elseif dist > 75 and dist <= 150 then # Increase check intervals self.WaitTime = 0.3 elseif dist > 32 and dist <= 75 then # Further increase check intervals self.WaitTime = 0.1 elseif dist < 32 then # Turn the missile down self:SetTurnRate(50) end end, CheckMinimumSpeed = function(self, minSpeed) if self:GetCurrentSpeed() < minSpeed then return false end return true end, SetMinimumSpeed = function(self, minSpeed, resetAcceleration) if self:GetCurrentSpeed() < minSpeed then self:SetVelocity(minSpeed) if resetAcceleration then self:SetAcceleration(0) end end end, GetDistanceToTarget = function(self) local tpos = self:GetCurrentTargetPosition() local mpos = self:GetPosition() local dist = VDist2(mpos[1], mpos[3], tpos[1], tpos[3]) return dist end, } TypeClass = TIFMissileNuke01

From that, I believe the lines that are useful are in the OnImpact function, but I have no idea how to transfer it into a kamikaze weapon, or just any sort of onfire command.

a daethnuke weapon is never really fired in the normal way, so an onfire callback is not needed.

in the death thread the script in unit.lua checks for any weapons with the DeathNuke label and fires then by calling weapon:Fire() which is what you are seeing defined here.

or something like that anyway.

is this from the acu script or something?

why dont you look at the nuke weapon and its projectile script instead?
but yes nukes do work differently, they just end up calling that fire function one way or another since they have complex stuff going on especially with the effects and damage rings.
it could be placed in the OnImpact callback of a projectile for example, but you could call it on beetle death or OnFired, then set up the weapon to be a dummy and deal damage with just the script.

It was working in my mod 'Tokytos balanced beetle''. But something was changed and it no longer functions :S

Maybe you can check it out, might or might not help.

Nuke "Fire Beetle"

2016-12-06T19:50:25+02:00

Hi Faf,
I've been trying to understand how nuke weapons work with considerable difficulty.

The kamikaze weapon seems easy enough to understand, in cybranweapons.lua it sets up the effects, in defaultweapons.lua it does the damage... But nukes don't appear to work the same way?

Why is the code under a Fire function, and not an OnFire? How would I sub in these details into the Fire Beetle?
Sorry that my question isn't very pointed, I really have no idea how to get this going!

Code:: local NukeDamage = import('/lua/sim/NukeDamage.lua').NukeAOE DeathNukeWeapon = Class(BareBonesWeapon) { OnFire = function(self) end, Fire = function(self) local bp = self:GetBlueprint() local proj = self.unit:CreateProjectile(bp.ProjectileId, 0, 0, 0, nil, nil, nil):SetCollision(false) proj:ForkThread(proj.EffectThread) -- Play the explosion sound local projBp = proj:GetBlueprint() if projBp.Audio.NukeExplosion then self:PlaySound(projBp.Audio.NukeExplosion) end proj.InnerRing = NukeDamage() proj.InnerRing:OnCreate(bp.NukeInnerRingDamage, bp.NukeInnerRingRadius, bp.NukeInnerRingTicks, bp.NukeInnerRingTotalTime) proj.OuterRing = NukeDamage() proj.OuterRing:OnCreate(bp.NukeOuterRingDamage, bp.NukeOuterRingRadius, bp.NukeOuterRingTicks, bp.NukeOuterRingTotalTime) local launcher = self.unit local pos = proj:GetPosition() local army = launcher:GetArmy() local brain = launcher:GetAIBrain() local damageType = bp.DamageType proj.InnerRing:DoNukeDamage(launcher, pos, brain, army, damageType) proj.OuterRing:DoNukeDamage(launcher, pos, brain, army, damageType) -- Stop it calling DoDamage any time in the future. proj.DoDamage = function(self, instigator, DamageData, targetEntity) end end, }
