Help point me in the right ""Direction""

So currently, i am to edit the heli script and i already have it so it says the road but i also want it to convert GetEntityHeading(vehicle) into Cardinal Direction so i can use it in a Text Component String. so if anyone knows how i would do that please let me know :slight_smile:

Hey, by direction do you mean the direction of the car that the heli is looking at?
I’m also guessing you want it in North, East, South and West right?

Yeah, i tried to use one array from a compass hud script but it breaks the heli script function.

Wanna post the code that broke in here a sec?

Heading is in right-handed degrees relative to North.
Adapt this to whatever language you’re using.

cardinalDirections = [“North”, “West”, “South”, “East”]
index = floor(heading / 90)
return cardinalDirections[index]

7 
local directions = { [0] = 'N', [45] = 'NW', [90] = 'W', [135] = 'SW', [180] = 'S', [225] = 'SE', [270] = 'E', [315] = 'NE', [360] = 'N', }

while true do
	Citizen.Wait(0)
	for k,v in pairs(directions)do
		if vehicle ~= nil then
			direction = GetEntityHeading(vehicle)
			if(math.abs(direction - k) < 22.5)then
				direction = v
				break;
			end
		end
	end
end

^^^ LUA btw forgot to mention

The direction variable should now be the vehicles direction.
If you only want N, E, S and W just remove the middle ones from the table.
That should work, let me know!

I tried using your snippet but every time i opened up the camera and tried to lock on to the vehicle it crashes the hud. heres some code so if i messed up you can see it.

function RenderVehicleInfo(vehicle)
	if DoesEntityExist(vehicle) then
		local model = GetEntityModel(vehicle)
		local vehname = GetLabelText(GetDisplayNameFromVehicleModel(model))
		local licenseplate = GetVehicleNumberPlateText(vehicle)
		local direction = GetEntityHeading(vehicle)
		local directions = { [0] = 'N', [45] = 'NW', [90] = 'W', [135] = 'SW', [180] = 'S', [225] = 'SE', [270] = 'E', [315] = 'NE', [360] = 'N', }

		while true do
			Citizen.Wait(0)
			for k,v in pairs(directions)do
				if vehicle ~= nil then
					direction = GetEntityHeading(vehicle)
					if(math.abs(direction - k) < 22.5)then
						direction = v
						break;
					end
				end
			end
		end
		if speed_measure == "MPH" then
			vehspeed = GetEntitySpeed(vehicle)*2.236936
		else
			vehspeed = GetEntitySpeed(vehicle)*3.6
		end
		local x,y,z = table.unpack(GetEntityCoords(vehicle, false))
		local streetName, crossing = GetStreetNameAtCoord(x, y, z)
			streetName = GetStreetNameFromHashKey(streetName)
		local location = ""
		if crossing ~= 0 then
			crossing = GetStreetNameFromHashKey(crossing)
			location = direction .. " | " .. streetName .. ", " .. crossing
		else
			location = direction .. " | " .. streetName 
		end
		SetTextFont(0)
		SetTextProportional(1)
		if vehicle_display == 0 then
			SetTextScale(0.0, 0.49)
		elseif vehicle_display == 1 then
			SetTextScale(0.0, 0.55)
		end
		SetTextColour(255, 255, 255, 255)
		SetTextDropshadow(0, 0, 0, 0, 255)
		SetTextEdge(1, 0, 0, 0, 255)
		SetTextDropShadow()
		SetTextOutline()
		SetTextEntry("STRING")
		if vehicle_display == 0 then
			AddTextComponentString("Speed: " .. math.ceil(vehspeed) .. " " .. speed_measure .. "\nModel: " .. vehname .. "\nLocation: " .. location)
		elseif vehicle_display == 1 then
			AddTextComponentString("Model: " .. vehname .. "\nPlate: " .. licenseplate)
		end
		DrawText(0.45, 0.9)
	end
end

You caught me just as I was leaving for work, I’ll be back in a few hours and check then.

Try deleting the break, any errors?

Here’s a working code. Have just tested it a couple of times on my server. Had the same issue with GameTimeLewis’ code as you, so this should solve it for you, too.

function RenderVehicleInfo(vehicle)
if DoesEntityExist(vehicle) then
local model = GetEntityModel(vehicle)
local vehname = GetLabelText(GetDisplayNameFromVehicleModel(model))
local licenseplate = GetVehicleNumberPlateText(vehicle)

  -- Location of target vehicle 
  local x,y,z = table.unpack(GetEntityCoords(vehicle, false))
    local streetName, crossing = GetStreetNameAtCoord(x, y, z)
    streetName = GetStreetNameFromHashKey(streetName)
    local location = ""
  		if crossing ~= 0 then
  			crossing = GetStreetNameFromHashKey(crossing)
  			location = streetName .. ", " .. crossing 
  		else
  	location = streetName 
  end

  -- Heading of target vehicle
  	local directions = { [0] = 'North', [45] = 'North-West', [90] = 'West', [135] = 'South-West', [180] = 'South', [225] = 'South-East', [270] = 'East', [315] = 'North-East', [360] = 'North', }
  for k,v in pairs(directions)do
  	direction = GetEntityHeading(vehicle, false)
  	if(math.abs(direction - k) < 22.5)then
  		direction = v
  		break;
  	end
  end		
  
  if speed_measure == "MPH" then
  	vehspeed = GetEntitySpeed(vehicle)*2.236936
  else
  	vehspeed = GetEntitySpeed(vehicle)*3.6
  end
  SetTextFont(0)
  SetTextProportional(1)
  if vehicle_display == 0 then
  	SetTextScale(0.0, 0.40)
  elseif vehicle_display == 1 then
  	SetTextScale(0.0, 0.40)
  end
  SetTextColour(255, 255, 255, 255)
  SetTextDropshadow(0, 0, 0, 0, 255)
  SetTextEdge(1, 0, 0, 0, 255)
  SetTextDropShadow()
  SetTextOutline()
  SetTextEntry("STRING")
  if vehicle_display == 0 then
  	AddTextComponentString("Speed: " .. math.ceil(vehspeed) .. " " .. speed_measure .. "\nModel: " .. vehname .. "\nPlate: " .. licenseplate)
  elseif vehicle_display == 1 then
  	AddTextComponentString("Heading: " .. direction .. "\nLocation: " .. location .. "\nSpeed: " .. math.ceil(vehspeed) .. "\nModel: " .. vehname .. "\nPlate: " .. licenseplate)
  end
  DrawText(0.45, 0.8)

end
end

This is the complete function, including the text display. Just substitute it in heli_client.lua (lina 576 onwards for me). If you want to edit what is displayed how, edit the AddTextComponentString lines accordingly. The text size is above that in SetTextScale(0, 0.X). Just edit the X to make it smaller or larger.

Awesome! Thanks for the help and the code.
