Interaction with transport

[fairyoggy]

How can I interact with nearby vehicles?

For example, a car is standing in front of me and I want to close or open door, namely it. How can I do it?

Not exactly sure what your question is. But I do believe this topic could help you out: 

Check out 'myonlake's' reply on it. He draws a colshape on the players position and warps all vehicle within that range to his location.
You could use this code as well but instead of warping the vehicles, you could do other things with them like opening or closing the doors.

Is this what you were looking for?

@Bartje I think it can help, but I don’t understand how to fix it.

addCommandHandler("wv", 
function(player, cmd) 
     local element = "vehicle" 
     local radius = 3 
     local x, y, z = getElementPosition(player) 
     local colshape = createColSphere(tonumber(x), tonumber(y), tonumber(z), tonumber(radius)) 
     for index, value in ipairs(getElementsWithinColShape(colshape, element)) do 
		  setVehicleLocked ( element, true )
          outputChatBox("lock", player, 220, 220, 0) 
     end 
end)

I think that Bartje has given you a really good script. Using the recommended script you can create a "remote car key" script where you lock all vehicles that are close to your player. Let me help you by fixing it:

addCommandHandler("wv", 
function(player, cmd) 
     local radius = 3 
     local x, y, z = getElementPosition(player) 
     local colshape = createColSphere(tonumber(x), tonumber(y), tonumber(z), tonumber(radius)) 
     for index, value in ipairs(getElementsWithinColShape(colshape, "vehicle")) do 
		  setVehicleLocked ( value, true )
          outputChatBox("lock", player, 220, 220, 0) 
     end 
end)

@The_GTA Okay, but if there are 2 cars nearby, and you need to close only one of them

How do you want to decide which car they player "needs" or wants to close? Does the player have a list of cars that he owns?

I made a parameter for each cars "uid"

For example, we have

setElementData(car,"uid",0) -- car1
setElementData(car,"uid",1) -- car2

How can I open / close, for example, a car with "uid" 0

      if (getElementData(value, "uid") == 0) then
        setVehicleLocked ( value, true )
        outputChatBox("lock", player, 220, 220, 0) 
        break -- only one car.
      end
    end 
end) 

The line that I added is line 7. If you have a way to get the real "uid" by player then please modify that if-condition.

very nice, everything works perfect, thank you very much!

@The_GTA Hi again. One more question about this code. If there are no cars in the radius, how can I check this? For example, if there are no cars in the radius, a chat message is displayed

function lockCar(player, cmd)
	local radius = 3
	local x, y, z = getElementPosition(player)
	local vehiclesAround = getElementsWithinRange(x, y, z, radius, "vehicle")
	local vehicleElement = false

	if #vehiclesAround == 0 then
		outputChatBox("no vehicles around", player, 220, 220, 0)
		return
	end

	for i = 1, #vehiclesAround do
		vehicleElement = vehiclesAround[i]

		if getElementData(vehicleElement, "uid") and getElementData(vehicleElement, "uid") == 0 then
			setVehicleLocked(vehicleElement, true)
			outputChatBox("lock", player, 220, 220, 0)
			break
		end
	end
end
addCommandHandler("wv", lockCar)

Here you go, i also changed loop to faster, and we don't need colshape to get vehicles around. (+problem is that, that you create colshape and never delete it)

Everything works as it should, thanks.

But I would like to know the nuances about the past code, what is wrong. I added delete colshape but did not post here.

local colshape = createColSphere(tonumber(x), tonumber(y), tonumber(z), tonumber(radius)) 

If you create colshape, and not delete it it will stay on map until resource restart, wanna see? After using your command follow steps below.

Execute this command in admin panel (Resources > Execute command)

setDevelopmentMode(true)

for client & server.

And then, simply write:

/showcol

in chat.

I've added additional element data check, so if vehicle doesn't have such element data, it wouldn't compare number with boolean. Besides, my version of code is somewhat faster, because of integer loop (you can't really see difference, but it's better to use it anyways)

Why after all people use ipairs without sensible reason? I don't know, maybe because some of them lazy, or they don't even know that you can use int loop.

Good points, majqq! Let me comment on your details.

Indeed the integer loop is 100% equivalent to ipairs. Under the hood ipairs calls a function for each iteration to receive the next item while the integer loop is pure Lua bytecode. One could ask why did the Lua developer not optimize ipairs in the compiler to be a simple integer loop? Clearly he did not care about performance. So I argument that Lua was not designed to be performant. But don't get me wrong: due to per-frame event handlers you clearly need good performance or else you could destroy somebody's gameplay experience with bad scripts!

I think it has been a good idea to replace the colshape with the getElementsWithinRange function. Since OP did not ask about optimizations I was sticking to the script for simplicity's sake. Thank you for pointing it out because OP seems to like your improvement.
