Price ($$) based on getDistanceBetweenPoints2D

[Hero192]

Hey guys,

today im making transport marker and i want make the price be as distance between player Position and markers Position

Also i want the distance price shows on the gridlist i tried that but doesn't works anymore..

Please guys help me out

Please try to help me i really stuck here

--Server side:

local markers = { --Markers table

Anyone?

[JR10]

Why are you getting the distance on resource start? Also, source in onResourceStart is the root element.

[Hero192]

I fixed the code but i get only distance for one marker and not all markers and i want to show the cash based on distances to the gridlist help me please

local moneyTable = { 
 {1111}, -- How to remplace the argument [1] in theTable by distance numbers as price 
 {1111}, 
 {1111}, 
 {1111}, 
} 
markerpos = {} 
playerpos = {} 
  
addEventHandler("onResourceStart",resourceRoot, 
function () 
        for index, data in pairs(markers) do 
        local busmarker = createMarker(data.x, data.y, data.z-1, "cylinder", 1.5,247,187, 7, 120) 
        markerpos = { getElementPosition( busmarker ) } 
        addEventHandler("onMarkerHit",busmarker,onMarkerHit)    
   end 
end) 
  
addEvent ("warpplayer",true) 
addEventHandler ("warpplayer",root, 
function () 
     local px, py, pz = unpack ( playerpos ) 
     local mx, my, mz = unpack ( markerpos ) 
     playerpos = { getElementPosition( source ) } 
     local distance = getDistanceBetweenPoints2D ( px, py , mx, my ) 
     local cash = math.floor(distance / 2) 
     if ( getPlayerMoney ( source ) < cash ) then 
    outputChatBox (" You need ".. cash .."$ to use this service.", source, 255,0,0) 
  else 
     takePlayerMoney (source, cash ) 
   end 
end)

Because you're always getting the position of the last busmarker created and setting it to the global variable 'markerpos'. The logic is not even close to being correct.

You need to find the marker on warpplayer to get its position.

[Hero192]

Can you please do it for me i tried alot of time before i post any thing but i fails

[Hero192]

anyone can help me?

[JR10]

Post the rest of the code.

[Hero192]

local markers = { --Markers table 
[1]={x=2220.43, y=2469.49, z=10.82, bx=2221.24, by=2468.76, blip=8, dim=0, int=0}, 
[2]={x=1625.00, y=1850.43, z=10.82, bx=1625.00, by=1850.43, blip=8, dim=0, int=0}, 
[3]={x= 1718.26, y=1484.68, z=10.82, bx=1718.26, by=1484.68, blip=8, dim=0, int=0}, 
[4]={x=1214.07, y=-1316.54, z=13.56, bx=1214.07, by=-1316.54, blip=8, dim=0, int=0}, 
} 
  
local moneyTable = { 
[1]={1111}, -- How to remplace the argument [1] in theTable by distance numbers as price 
[2]={1111}, 
[3]={1111}, 
[4]={1111}, 
} 
busmarker = {} 
playerpos = {} 
  
addEventHandler("onResourceStart",resourceRoot, 
function () 
        for index, data in pairs(markers) do 
        local busmarker = createMarker(data.x, data.y, data.z-1, "cylinder", 1.5,247,187, 7, 120) 
        markerpos = { getElementPosition( busmarker ) } 
        addEventHandler("onMarkerHit",busmarker,onMarkerHit)    
   end 
end) 
  
addEvent ("warpplayer",true) 
addEventHandler ("warpplayer",root, 
function () 
     local px, py, pz = unpack ( playerpos ) 
     local mx, my, mz = unpack ( markerpos ) 
     playerpos = { getElementPosition( source ) } 
     local distance = getDistanceBetweenPoints2D ( px, py , mx, my ) 
     local cash = math.floor(distance / 2) 
     if ( getPlayerMoney ( source ) < cash ) then 
    outputChatBox (" You need ".. cash .."$ to use this service.", source, 255,0,0) 
  else 
     takePlayerMoney (source, cash ) 
   end 
end)   
  
function onMarkerHit(hitPlayer) 
    if ( getElementType ( hitPlayer ) == 'player' and not isPedInVehicle ( hitPlayer ) and not isPedDead ( hitPlayer ) ) then 
    triggerClientEvent(hitPlayer,"showgui",hitPlayer,moneyTable) 
  end 
end 

[JR10]

This is different from your original code. Is 'source' defined in warpplayer?

local px, py, pz = getElementPosition(client) 

[Hero192]

so you mean that?

still doing the same and the problem is when i selecte the gridlist to check the prices of markers distance it give me the same price..

you said: You need to find the marker on warpplayer to get its position.

how to do that?

addEvent ("warpplayer",true) 
addEventHandler ("warpplayer",root, 
function () 
     local px, py, pz = getElementPosition(client) 
     local mx, my, mz = unpack ( markerpos ) 
     local distance = getDistanceBetweenPoints2D ( px, py , mx, my ) 
     local cash = math.floor(distance / 2) 
     if ( getPlayerMoney ( source ) < cash ) then 
    outputChatBox (" You need ".. cash .."$ to use this service.", source, 255,0,0) 
  else 
     takePlayerMoney (source, cash ) 
   end 
end)   
  

[JR10]

You're already doing that. Check /debugscript 3 for errors. Post the client side script and make sure that source is defined.

I suggest you start learning more.

[Hero192]

There's no errors,

client side:

local root = getRootElement() 
local client = getLocalPlayer() 
buswindow = guiCreateWindow(419,244,500,287,"Bus",false) 
guiSetVisible (buswindow, false) 
guiWindowSetSizable(buswindow,false) 
busGrid = guiCreateGridList(9,20,482,224,false,buswindow) 
costColumn = guiGridListAddColumn(busGrid,"Price:",0.7) 
spawnBtn = guiCreateButton(17,247,157,31,"Spawn",false,buswindow) 
rejectBtn = guiCreateButton(329,247,157,31,"Cancel",false,buswindow) 
  
addEvent("showgui",true) 
addEventHandler("showgui",root, 
function (moneyTable) 
   guiSetVisible(buswindow,true) 
   showCursor(true) 
   guiGridListClear(busGrid) 
  for i,v in ipairs (moneyTable) do 
  local row = guiGridListAddRow (busGrid) 
  guiGridListSetItemText (busGrid, row, 1, v[1], false, false) 
    end 
end) 
  
addEventHandler ("onClientGUIClick", root, 
function () 
      if (source == rejectBtn) then 
      guiSetVisible(buswindow,false) 
      showCursor(false) 
     elseif (source == spawnBtn) then 
      local row,col = guiGridListGetSelectedItem(busGrid) 
      if row and col and row ~= -1 and col ~= -1 then 
      guiSetVisible(buswindow,false) 
      showCursor(false) 
      triggerServerEvent("warpplayer",client,guiGridListGetSelectedItem(busGrid)+1) 
     end 
   end 
end) 

[JR10]

Your code is a total mess. Like I said, you should try to learn more.

@line33 client is not defined, and you're sending the selected item but you're doing nothing with it server-side.

I can't help you if none of your code make any sense.

[Hero192]

If i was good i wasn't going to post this topic, i posted this to find someone who can give me his hand and help me out to correct and learn from my fails , be sure next time i can't do the same fail if you helped me

[JR10]

My point is, instead of bumping into errors, warnings and logical faults, learning the basics and looking at examples can make it much easier.

[Hero192]

client is defined with localPlayer, look at the top of my code and i know basic lua scripting .. my problem is with mta functions
