 Reversed Air Resistance - Exponential Speed Increases Hi all.
I'm trying to create a particle to be fired from a bomb or from a weapon, that begins with a movement speed of 5, yet increases drastically for each second it's active. I've tried setting a negative AirResistance variable to the particle, yet that does absolutely nothing to the speed at which it progresses.
I'm looking for a way to create the desired effect, preferably just by modifying the .ini file, but I'll have a go at Lua if necessary.
It seems many variables can be modified by making them negative, I guess I just got my hopes up about AirResistance a bit too early. Thanks in advance!

Re: Reversed Air Resistance - Exponential Speed Increases Code: function Create(self)
self.AccelTimer = Timer();
self.acceleration = 5; -- acceleration
self.accelpertime = 1000; -- per time
end
function Update(self)
if self.AccelTimer:IsPastSimMS(self.accelpertime) then
self.AccelTimer:Reset();
self.Vel = Vector(self.Vel.X,self.Vel.Y):SetMagnitude(self.Vel.Magntiude+self.acceleration);
end
end Attach that script to your particle.

Re: Reversed Air Resistance - Exponential Speed Increases Thankyou sir, with a bit of number tweaking it worked like a charm

Re: Reversed Air Resistance - Exponential Speed Increases why not just Code: function Update(self)
self.Vel = self.Vel * 1.5 --put your number here
end ? obviously 1.5 will make it go inordinately fast, but tweaking should be easy enough.

Re: Reversed Air Resistance - Exponential Speed Increases How about this Code: function Create(self)
self.A = <Insert starting speed of choice>;
end
function Update(self)
self.Vel = self.Vel.Normalized * self.A;
self.A = self.A + <Insert increment of choice>;
end
?

Re: Reversed Air Resistance - Exponential Speed Increases How about directly reading from Air resistance and applying only if it's negative?

Re: Reversed Air Resistance - Exponential Speed Increases cause that would be silly when you could do it with an int and save reading the airresistance, and check how it works with PresetMan:ReloadAllScripts()

Re: Reversed Air Resistance - Exponential Speed Increases Right, so you purchased already? To get rid of the crabling, go to your forum profile settings and add your reg key to the corresponding slot.
