speedometer

[Hugos]

I have a function by means of which I learn car speed:

function GetSpeed()
	if isPedInVehicle(getLocalPlayer()) then
		vehicle = getPedOccupiedVehicle(getLocalPlayer())
		px, py, pz = getElementVelocity(vehicle)
		speed = ((px^2 + py^2 + pz^2)^(0.5)) * 111.847
		mph = math.floor(speed)
	else
		guiSetVisible(disc, false)
		guiSetVisible(needle, false)
	end	
end

I have a speedometer and an arrow (to watch pictures). How to make that the arrow was smoothly scrolled and specified what car speed now?

1) Your function is wrong

2) You need to use DX functions

You were helpful AF, bro Keep up the good work!

Use the getElementSpeed function from WIKI to get the current speed. It works quite well.

For the arrow of the speedometer:
You know that the speedo can show 260 max. You know the degree for the 0 on the speedo and the degree for 260. Now you can divide the current speed of the vehicle by 260 and then you get the relative number to multiply the degrees with.
So like:

local arrowRotation = 0; -- This will be the actual rotation of the arrow.

local vehicleSpeed = 180; -- This will serve as the current speed of your vehicle. You get this with getElementSpeed
local speedoMaxSpeed = 260;
local degreesFromZeroToMax = 180; -- This is the degrees between 0 and 260 for example

arrowRotation = (vehicleSpeed/speedoMaxSpeed)*degreesFromZeroToMax;

I hope it works. It's been a long time since I made something like this.

About dx. Yup! You HAVE to use dx for this.
