What do you need help with? V3

[Hyper Iguana]

What's the most efficient way to find an entity spawned by the map each time. The entity's index changes.

[amkoc]

[QUOTE=Disseminate;38878961]Are the lines parallel? If so, you can use util.DistanceToLine for any point.

Are they skew? Then the distance varies.
[/QUOTE]

Could be either, think a don't-cross-the-beams sort of thing

[disseminate]

Google intersection of two lines in R3.

Probably a quick for loop through ents.GetAll()

SoundScapeTable = {}
function FindSoundScapes() //finds all of the map's soundscape entities and adds them to a table
	for k, v in pairs(ents.GetAll()) do
		if(v:GetClass()=="env_soundscape") then
			table.insert(SoundScapeTable, v);
		end
	end
end
FindSoundScapes()

I need some help figuring out how to make a polygon draw inside the viewmodel (Circular Render Target, RT scope n' all)

if CLIENT then
	function SWEP:ViewModelDrawn()
		self.AcogGlass = Material( "models/wystan/attachments/acog/lense" )
		self.AcogRT = GetRenderTarget( "acog_glass_rt", 512, 512, false )
		self.AcogGlass:SetTexture( "$basetexture", self.AcogRT )

		local vm = self.Owner:GetViewModel() 
		local bone = vm:LookupBone("v_weapon.sg552_Parent")
		if !bone then print("bone doesnt exist") end
		local pos, ang = Vector(0,0,0), Angle(0,0,0)
			local m = vm:GetBoneMatrix(bone)
			if (m) then
				pos, ang = m:GetTranslation(), m:GetAngles()
			end
		pos = pos + Vector(0,0,0)
		ang = ang + Angle(0,0,0)
		print(pos)
		print(ang)
		local Radar = {}
		Radar.circle= {}
		Radar.res = 52
		Radar.radarRadius = 100;
		for i=1,Radar.res do
			Radar.circle[i] = {}
			Radar.circle[i].x = pos.x + math.cos(math.rad( (i*360)/Radar.res ))*Radar.radarRadius*0.99
			Radar.circle[i].y = pos.y + math.sin(math.rad( (i*360)/Radar.res ))*Radar.radarRadius*0.99
			Radar.circle[i].u = (math.cos(math.rad(  (i*360)/Radar.res )) + 1)*0.5 
			Radar.circle[i].v = -(math.sin(math.rad( (i*360)/Radar.res )) + 1)*0.5 
		end
		cam.Start3D(pos, ang , 4, pos.x, pos.y, 512,512)
			surface.SetMaterial(self.AcogGlass)
			surface.SetDrawColor(255, 255, 255, 255)
			surface.DrawPoly(Radar.circle)
			
		cam.End3D()
		render.SetViewPort( pos.x, pos.y, 20, 20 )
			render.SetRenderTarget( old )
						

	end
end)
--circular radar code obviously jipped from BaseWars radar. With permission!

All inside of ViewModelDrawn, and the drawpos is the same code from SWEP creation kit. i honestly cannot manage to do this.

Can I somehow disable tabs painting on DPropertySheet?
Using Paint will only make the background disappear :/

Create your own skin and edit the DPropertySheet tabs with your own paint func.

Multiply the rate by FrameTime()

That being said you should just do it procedural instead of holding on to a variable.

I'm using the net library and I'm wondering how I should use net.WriteUInt().

unsigned int has the same range as the signed one, it's just that all numbers have to be > 0 (correct me if I'm wrong, I'm really tired). And the message size is the integer's size in bits.

(signed) integers use the first bit to signify +ve or -ve
unsigned integers can therefore use the extra bit to signify a larger number, since they are always positive

So on a 32 bit system, we have integers ranging from –2,147,483,648 to 2,147,483,647 (normal)
and unsigned integers from 0 to 4,294,967,295

As you can see, both have the same size (32 bits) but can represent different ranges. As for getting the size of the integer... if you know you're dealing with small integers, such as 1 through 4 for example, you could get away with putting a size of 3 bits. This is purely for the sake of efficiency. If you have no idea what size, you can use 32, which would give you the range of the usigned integer above. It would be inefficient though, and I'd suggest looking into some sensible value ranges. If you're super keen, you could try detecting the size in bits of a number in Lua. To do that you could convert to binary using a fairly simple method, then convert that to a string and count how many elements in that string (representing the number of bits you need to send i.e the size argument)

[Labrasones]

[QUOTE=KatNotDinner;38891305]unsigned int has the same range as the signed one[/QUOTE]
An unsigned int and an int use the same number of bytes, but the unsigned int has a much larger range than the regular int. Roughly twice as large actually. Since the number range that normally maps from a negative to a positive now only maps from 0 to positive.
Here are the ranges of an average int.

signed: -2147483648 to 2147483647
unsigned: 0 to 4294967295

Edit: Ninja'd with a better description anyway.

[QUOTE=M0dSe7en;38882002]Anyone know how to fix this PCF bug I'm getting? I made a small effect for testing, and I used this script to see if I'm using ParticleEffectAttach() correctly:

[lua]

if (CLIENT) then game.AddParticles( "particles/test1.pcf" ) end
function AttachParticle()
for k,v in pairs(player.GetAll()) do
if v:IsPlayer() && v:Alive() then
local id = v:LookupAttachment("eyes")
//local att = v:GetAttachment(id)
ParticleEffectAttach("test2",PATTACH_ABSORIGIN_FOLLOW,v,id)
end
end
end
concommand.Add("test_particle", AttachParticle)
function StopParticles()
for k,v in pairs(player.GetAll()) do
if v:IsPlayer() then v:StopParticles() end
end
end
concommand.Add("stop_particles", StopParticles)
[/lua]

The effect works, but it only spawn at Vector(0,0,0) on whatever map i choose.
In gmod 12, I used ply.GetAttachment( attachmentID ) rather than just ply.LookupAttachment( string ) and it worked fine.
This is the first effect I made, so I don't know if I'm using the function wrong, or if my effect is bugged. Thanks.[/QUOTE]
