increase crowbar range/width

Garry's Mod coding
#1

I have a swep I’m working on that is a big sword, I have the model and animations down (as that is my skill), along with some simple lua code. The code uses the crowbar as a base and I feel it is too limited for a big sword. Is it possible to increase the range that I can hit with the weapon and change the hit area from a bullet hole to maybe a larger diameter?
For the record, I don’t really know how to program in lua, so I apologize for any ignorance in advance.

Oh yeah, forgot to post this:

What crowbar as base? Show what code you already have.

#3

Oh yeah, that’d probably help, sorry.

#4

70 on this line is the range:


local sdest = spos + (self.Owner:GetAimVector() * 70)

Change it to whatever you need.

This line:


SWEP.AdminSpawnable	 = true

Doesn’t do anything for almost a year now.

This line:


SWEP.base					= "stunstick"

Won’t do anything. First it’s SWEP.Base, and “stunstick” isn’t a valid weapon base and you can only use Lua weapons as base.

#5

Okay, and what about increasing the hit diameter? Right now it is only the size of a pistol shot, is it possible to make it as large as a shotgun blast (basically the majority of the player’s screen)?

#6

You will have to perform traces in the areas that you want to give the illusion of a blade swiping.

#7

I found the code for increasing the hit diameter and increased it(still playing with the numbers though, thus the # sign in the code):



	bullet = {}
	bullet.Num    = #
	bullet.Src    = self.Owner:GetShootPos()
	bullet.Dir    = self.Owner:GetAimVector()
	bullet.Spread = Vector(#, #, #)
	bullet.Tracer = 0
	bullet.Force  = 3
	bullet.Damage = 120	//originally 60

BUT
changing that 70 for the range didn’t do anything.

#8

Shooting several bullets with spread might simulate a larger range, but several of those bullets could hit the one target.
You can increase the size of the trace in your original code by playing with the *10 after kmins and kmaxs. It is using those variables to define the size of the hull trace.

#9

Well the spread was a bad idea, and I found where to modify the range


if trace.HitPos:Distance(self.Owner:GetShootPos()) <= 120 then

I changed the *10 for kmin and kmax to higher values, but I’m not noticing any differences in-game.

#10

Try multiplying the vector components themselves, like



   local kmins = Vector(-10,-10,-10)
   local kmaxs = Vector(10,10,10)
#11

That won’t make any difference, Vector(1,1,1)*-10 is the same as Vector(-10,-10,-10), but if you want to make a change to the code you only have to change 1 number instead of 3.

#12

Don’t you have to multiply it by the respective components? Unless you only want one component to be multiplied, at which point you’d have to define it after typing out the variable.
like for a local variable that is an angle:

angle.yaw * 10

?

#13

I’m not sure about Angles but I know for certain that if you multiply a Vector by a Number it multiplies all components.

#14

Angles and Vectors can both be multiplied by scalars.
