Re: Floating object attached to assigned actor.

INI:

Code:

AddEffect = MOSParticle
   PresetName = Stat
   Mass = 0.001
   GlobalAccScalar = 0.0
   LifeTime = 5150
   HitsMOs = 0
   GetsHitByMOs = 0
   ScriptPath = ActionHeroSoldier.rte/Devices/PartEff.lua
   SpriteFile = ContentFile
      FilePath = TesterBreachC4.rte/Devices/Timer.bmp
   FrameCount = 7
   SpriteAnimMode = 0
   SpriteAnimDuration = 725
   SpriteOffset = Vector
      X = -10
      Y = -8
   Atom = Atom
      Material = Material
         CopyOf = Air
      TrailLength = 0

LUA:

Code:

function Create(self)
local curdist = 50
for i = 1,MovableMan:GetMOIDCount()-1 do
   gun = MovableMan:GetMOFromID(i);
   if gun.ClassName == "HDFirearm" and gun.PresetName == "C-4 placer" and (gun.Pos-self.Pos).Magnitude < curdist then
      actor = MovableMan:GetMOFromID(gun.RootID);
    if MovableMan:IsActor(actor) then
      self.parent = ToActor(actor);
         local Stat = CreateMOSParticle("Stat");
            Stat.Pos = self.parent.AboveHUDPos + Vector(0,1);
            MovableMan:AddParticle(Stat);
         end
      end
   end
end

As you could probably guess the lua is attached to the fired projectile (It's a timer charge that shows how long it takes before detonation is possible by manual control) and not the gun or the actor itself.

Should I apply the :

Code:

function Update(self)
   self.Pos = Vector(actor.Pos.X, actor.Pos.Y);
end

to a new LUA file and attach that to the MOSParticle 'Stat' ?

It works, though, but it'll stop working if I stop moving.

See title. An event triggers an animation loop displayed as a HUD status bar (Like the Jetpack fuel bar?) It spawns fine and sticks above the character and all that... ... it just doesn't stick TO the character, and stays in mid air if the player moves... So, basically, I have no idea how to do this and the search function has too much scatter and needless information about guns =.=

Find the nearest actor using SceneMan:ShortestDistance and (if it's a custom actor, check that the presetnames match) use it as the 'zero' vector to modify by your deltaY to get a point above it.

No no no, I mean, I already got it to spawn on the right spot, just not to stick to it. Should I make it an attachable instead of a particle/pixel/thingitisnow ?

You can't permanently attach anything with Lua, you have to reset it's position every frame (or every 50 ms or whatever).

Just do function Update(self) self.Pos = Vector(actor.Pos.X, actor.Pos.Y - howevermanypixels); end

Facepalms D'ah! T-thanks... Edit: Is it, like, possible to make a MOSParticle with a script that does that? Or do I need to make it an attachable after all?

It's quite possible, though I'd need more specifics on exactly how you're doing all this to tell you just how. Is it a custom actor, or a weapon effect, or what?

That which is following the actor can be anything, if that's your question.

Yeah, if I'm reading you you want the Stat particle to stay with the Actor, in which case you would put that Lua attached to Stat.

Facedesk I edited just as you posted. Uhm, well, it works, sort of. It just vanishes if I stay standing still.

6 seconds, so no... And if I do put it in the same lua document, I'm pretty sure the round fired (The bomb) will stick above my head instead... as the lua is for the round, and the particle is something different from the round and shouldn't be affiliated with the script written for the round... ... r-right? Edit: Tried it. Me exploding into 50000 fleshy bits should make it obvious enough.

Okay, then this is pretty simple. Have the lua attached to the fired shot spawn the MOSParticle. That MOSParticle will have a script to find the nearest actor (look at the homing missile for a quick example), which it will then designate as the "target". Then, just use the update position code to keep it attached.

I shouldn't be doing this at 0:33 AM after a party... urgh. Kay, here goes nothing... Edit: Nope, too tired. Will try tommorow, at work, or something.
