Code:
function Create(self)
   self.acceltimer = Timer();

   self.acceldelay = 100; -- time-delay between accelerations (in MS).
   self.acceleration = 2; -- scalar acceleration. 1 is no acceleration, 0.5 is deceleration by half previous vel, 2 is acceleration by double previous vel.
end

function Update(self)
   if self.acceltimer:IsPastSimMS(self.acceldelay) then
      self.Vel = Vector(self.Vel.X,self.Vel.Y)
   end
end

There's your acceleration/deceleration script.

In your script, where does it multiply the velocity by the acceleration? It looks to me like the update method isn't changing the velocity of whatever the script is attached to at all.

Change
Code:
      self.Vel = Vector(self.Vel.X,self.Vel.Y)
To
Code:
      self.Vel = Vector(self.Vel.X* self.acceleration,self.Vel.Y*self.acceleration)
Maybe?

Whoops, forgot to put that in. What 411570N3 said.

Yes all very well, and well done, but do you attach it to the bullet or the weapon?


Code:
AddEffect = MOPixel
   PresetName = *Bullet*
   ScriptPath = ???????/????.lua

Or
Code:
AddDevice = HDFirearm
   PresetName = *Weapon*
   ScriptPath = ???????/????.lua


Oops, it is a slightly old thread. Hope you don't mind.

You attach the script to the object that you're trying to deccelerate.

Soo.. The bullet.


Yeah i'll test this in a bit.
