[QUOTE=bobbleheadbob;47267780]I'll draw this out and give you the answer.

[editline]google[/editline]
Google came up with this:
R=V−2N(V⋅N)
R = reflected vector
V = Input Vector
N = Plane Normal

So
[lua]
function math.VectorReflect(vec,norm)
local ref = vec - 2 * norm * vec:Dot(norm)
return ref
end
[/lua][/QUOTE]

Curious, what did you google? Obviously I suck at google.

Also... I need to take more math classes or something because I don't know anything about dot products... is that just multiplication of two vectors?

So, this wouldn't work, then?

function math.VectorReflect(vec,norm)
	local ref = vec - 2 * norm * ( vec * norm )
	return ref
end

[editline]6th March 2015[/editline]

Research... no, vec * norm wouldn't work. I withdraw the question.

[QUOTE=GreyGeist;47267746]What is wrong with this recoil code? Seems to be extremely broken, to the point that the player's pitch can actually go way beyond where it should. How can I clamp this?

[/QUOTE]

Angles are between -180 and 180; you can use math.NormalizeAngle( Angle( 360, 0, 0 ).p ); for it to become 180. There are other methods of doing this too and you can manually clamp it by knowing the range - for example, this snippet to calculate the current angle yaw or whatever should be if rotating it at a set speed ( bound to time ) with an offset so other entities won't be in sync ( calculate self.Offset from 0-360 on entity creation ):

//
// Handles repetitive smooth rotational calculations into 1 line without the confusion and normalizes the angle ( -180 )
//
function math.rotate( _speed, _offset )
	return ( ( RealTime( ) * ( _speed || 180 ) + ( _offset || 0 ) ) % 360 ) - 180;
end
	

But, the solution for you could be simplified to simply be math.min or math.max of a value, you can also clamp the value... I'd recommend something like the rotation where it assumes 0-360 and subtracts 180 after it is done. math.Clamp( ( blah + 180 + kickback ) % 360, 0, 360 ) - 180; or so...

I'm using a shitty laptop on low settings. If it isn't clear, the issue is that for the 1-2 seconds while entering the vehicle, you can't move the camera.

Pretty much just do a trace on the door and get the normal, then get your angle from that. I can help you out more on Steam, I sent a request.

So this kind of goes with my last question but what is the thing that you call for the total amount of ammo a player has on the currently equipped gun? I already have the amount that the player has in the current clip.

Is there a function to collapse a sparse table into a sequential table?
for example:

1 = "One"
5 = "Five"
1200 = "Twelve-Hundred"

would become:

1 = "One"
2 = "Five"
3 = "Twelve-Hundred"

if not I might just make a Pull Request for it - sounds generic enough.

[editline]7th March 2015[/editline]

Oh and here's why:
[img]http://i.gyazo.com/b51740d7b6d5243992293f5a02b41bc5.png[/img]

[url]http://www.lua.org/cgi-bin/demo[/url][lua]local tab = {[1] = "One", [5] = "Five", [1200] = "Twelve-Hundred", abc = "Alphabet"}

print("=== BEFORE (ipairs) ===")
for k, v in ipairs(tab) do print(k,v) end

print("=== BEFORE (pairs) ===")
for k, v in pairs(tab) do print(k,v) end

local keys = {}

for k in pairs(tab) do
if type(k) == "number" then table.insert(keys, k) end
end

table.sort(keys)

local collapsedtab = {}
for k, v in ipairs(keys) do table.insert(collapsedtab, tab[v]) end

print("=== AFTER (ipairs) ===")
for k, v in ipairs(collapsedtab) do print(k,v) end

print("=== AFTER (pairs) ===")
for k, v in pairs(collapsedtab) do print(k,v) end[/lua]

(sorry for the ugly code, I literally did this in the browser)

Nup. You could make your own though.

[QUOTE=AIX-Who;47276612]Hey!, Anyone got any idea on how you make a circular avatar image?

You'd have to use stencils for that, I think I have a code that does this, actually.

Well, here it is, untested.

self.Avatar = vgui.Create("AvatarImage", self)
self.Avatar:SetPaintedManually(true)
end

function PANEL:PerformLayout()
self.Avatar:SetSize(self:GetWide(), self:GetTall())

local sin, cos, rad = math.sin, math.cos, math.rad

local function GeneratePoly(x, y, radius, quality)
local circle = {}
local tmp = 0
for i = 1, quality do
tmp = rad( i * 360) / quality
circle[i] = {x = x + cos(tmp) * radius, y = y + sin(tmp) * radius}
end
return circle
end

self.Poly = GeneratePoly(self:GetWide()/2, self:GetTall()/2, self:GetWide()/2, self:GetWide()*2)

Although i apparently have no avatar and its just a question mark, it may be something on my side

Try something like this;

avatar.Avatar:SetPlayer( LocalPlayer() )[/lua]

[Hoffa1337]

When changing player eye angles with calcview, why is the game still treating the mouse input as if the view was normal? If i rotate the players view 180 degrees on the roll or pitch axis the mouse movement gets inverted, how can I get around this?

You mean have the circle in focus and white background or what?

GoldTrigger just misunderstood a link I gave him in another thread (it's partly my fault - I just posted a link with no explanation).

GoldTrigger, the answer you're looking for is just a few posts above, in Post #4503 and #4505.
