How would I go about creating a timer that displays as "Minutes:Seconds". My gamemode at the moment is round based and I'd like to show the player how much time is remaining.

[lua]
local minutes = math.Round(time / 60)
local seconds = time - (minutes * 60)
[/lua]

There was some easier way though

Use the second argument.

Hi!
How would I measure driven kilometers (odometer)? Is there any function for this or must I make it myself? I would like to make on-screen odometer which starts measuring every time player sits in a car in addition to my speedo.

And while at it, how do you check is variable is declared?

Thanks!

How would one properly synchronize SWEPs? [B]IsFirstTimePredicted()[/B] doesn't seem to work. It messes up my PrimaryFire func. Any ideas?

Edit.
Made a [URL="http://www.facepunch.com/threads/1165351?p=34804867#post34804867"]thread[/URL] about this.

Is there anyway you could show me an example?

And while at it, how do you save a var so that is it usable next time function is called? Do you use global instead of local?

Thanks![/QUOTE]

Save current (old) position vector. Make a 1 second interval. Now for each second do:
get current pos. Calculate lenght between current vec and older one and add to a global var. Save current vec as old one. Repeat cycle.
The "global" var can simply be a networked int on an entity. And interval even 5 seconds.
Would write some real code, but I'm on a phone.

Oh, I get it now. But how do you get current position? (since wiki is down I cant look there :( )

Thanks!

One thing though. I read about calculating distance between two points:
"As you can see, this requires that you perform a square root. Square roots should be avoided like the plague if you want to write fast code. Only perform a Square Root if you really need to."
And since lua is scripting language ... :S

On a DListView, is it possible coloring the text on it, as of multiple colors?

Does that thread solve your question?

[Hugabuga]

Not realy, I've already checked the DListView options, but I haven't found any way of only changing the text color. I guess I can do my own skin tho.

yes its expensive. But you can lighten up the calculations if you do them only every 5 seconds. Calculate without Z axis if there are no hills.
IDEA:
calculate distance based on velocity and time! But wait... Probably still requires vector root calculation. And is not that reliable like 2 solid points.
So yeah, no way out.

[Panto]

You can try using the entity's velocity to get the speed in km/h.

I'm getting this error:

[gamemodes\mygm\gamemode\sql.lua:44] 'end' expected (to close 'function' at line 28) near '<eof>'
R

With this piece of code:

function DoesPlayerSQLExist(ply)//Line 28

	local steamID = ply:SteamID()
	Msg(ply:Nick().."'s Steam ID is: "..steamID.."\n Checking SQL record...")
	
	result = sql.Query("SELECT unique_id, money FROM player_info WHERE unique_id = '"..steamID.."'")
	if(result) then
		//Code for opening stats
		Msg(ply:Nick().."'s SQL record exists!\n")
	if(!result) then

		Msg(ply:Nick().."'s SQL does not exist!\n Creating Record!\n")
	else 
		Msg("Something went wrong checking "..ply:Nick().."'s SQL record\n")
	end
	
end

The error is definitely limited to this piece of code.

You are missing an end.
Posted second too late.

Edited for post below, end needs to be up a few lines under first if.

[joyenusi]

I didn't know that two if's in succession both required seperate ends. I just assumed the console was wrong and not me. Thanks a lot!

[QUOTE=Panto;34816116]You can try using the entity's velocity to get the speed in km/h.[/QUOTE]

Entity.GetVelocity returns a vector and to calculate a scalar lenght/power of it you need to use root fucntion with the vector.
What I proposed earlier with 2 vectors is more reliable than velocity * time.

Does anyone know a way to detect a collision between two objects? I know you can do it with SENTs using ENT:PhysicsCollide, but if I just have two jeeps that crash into each other, is there a way to detect that?

While raising the timer countdown time would lighten up the calculations it would also have a huge impact on precision on roads like this: [url]http://shrani.si/f/1p/M0/ZdaaBDn/1/example.png[/url]

Hmm, based on speed, I could try to squeeze something out.

distance = distance + LocalPlayer():GetVelocity():Length() / (1 / timer) * 0.00001905

This is probably lighter? Im interested how much time does GetVelocity() cost. If I make this calculation 10 times in a second or one square root in a second, is the first option still preferable :S

so we are stuck on this question :v:
[lua]
local distance = 0 --we need this outside the function
local pos1 = LocalPlayer():GetPos() --initial pos so its not nil and we also need this to save outside func
function calcDist()
local pos2 = LocalPlayer():GetPos() --current position vector
local lenght = pos1:Lenght(pos2)
distance = distance + lenght --might want to throw in your unit conversion here
pos1 = pos2 --so we get correct distance next time
end
timer.Create("distancecalculate interval",1,0,calcDist) -- check if interval is 1 second and times repeated = infinity[/lua]

Again, no way for me to check if this works. Look which way is better for you.

Could someone explain how I could make this camera rotate from a y axis around to move the camera slowly in front of me instead of just snapping to this view?
[lua]
hook.Add("CalcView", "CalcTheView", function(ply, pos, angles, fov)
local view = {}
view.origin = LocalPlayer():GetPos()-(LocalPlayer():GetAngles():Forward()*60)+Vector(0,-10,50)
view.angles = (LocalPlayer():EyePos() - view.origin):Angle()
view.fov = fov
return view
end)

hook.Add("ShouldDrawLocalPlayer", "MyHax ShouldDrawLocalPlayer", function(ply)
return true
end
[/lua]

how do i get an int value of player velocity and remove Z (up down)? i just want a value that shows directional velocity (flat surface)

I haven't worked with CalcView yet, but I think you need this:
