  1. Hello, I recently returned to making a server after a year and I wanted to remind myself how the "source", "root", "this", "sourceResource", "sourceResourceRoot", "client" etc. Elements worked. Unfortunately, when I checked the MTA wiki, I didn't understand any of these elements. In general, the best help would be if someone explained to me how these elements work on examples for AddEventHandler because in mta wiki there is only one example for a "source" and I guess "root"? element
  2. addEventHandler + group elements I noticed that some people like to add 10000000000000000 addEventHandlers for each element, while you probably only need 1 addEventHandler. Using ONE addEventHandler on a group of elements? Answer: local group = createElement("groupMyCutePeds") -- Create a custom element and save it in to the variable <group>. -- Create 3 peds. local ped1 = createPed(120, 5540.6654, 1020.55122, 1240.545) local ped2 = createPed(120, 5541.6654, 1021.55122, 1240.545) local ped3 = createPed(120, 5542.6654, 1022.55122, 1240.545) -- Set the parent of the 3 peds. setElementParent(ped1, group) setElementParent(ped2, group) setElementParent(ped3, group) -- Add an addEventHandler and use the <group> as <attachedTo> element. addEventHandler("onPedWasted", group, -- "onPedWasted" = serverside. "onClientPedWasted" = clientside. function () outputChatBox("One of my cute peds just died. ;'( No exceptions!") end) Code is untested, but the method is tested. Syntax for functions in example createElement syntax element createElement ( string elementType, [ string elementID = nil ] ) setElementParent syntax bool setElementParent ( element theElement, element parent ) addEventHandler syntax bool addEventHandler ( string eventName, element attachedTo, function handlerFunction, [ bool getPropagated = true, string priority = "normal" ] ) DO NOT disable getPropagated getPropagated: A boolean representing whether the handler will be triggered if the event was propagated down or up the element tree (starting from the source), and not triggered directly on attachedTo (that is, handlers attached with this argument set to false will only be triggered if source == this). If you disable this, children of the <group> element are not included. Make use of the element tree Element tree For applying addEventHandlers to elements created by the resource: Use: resourceRoot / getResourceRootElement For applying addEventHandlers to elements created by scripts of the resource: Use: getResourceDynamicElementRoot For applying addEventHandlers to elements created by maps of the resource: Use: getResourceMapRootElement I hope your code will be without... print(10^10^10^10) -- Print here: https://www.lua.org/cgi-bin/demo ...addEventHandlers in the future.
  3. The question is the following needs to get an item from the server side to the client side, how can I do it? (Elements such as markers, vehicles etc.)
  4. I would like to ask where I can find a guide on: createElement, ElementData, Shaders etc. I need it because soon I will be making radar and inventory system. It would be nice if you would share your knowledge on the things I gave
  5. I've been working on a script that realistically manipulates the wheels. I've gotten to the point I can hide the original wheels, in hopes I can later attach a new set in the same place. I'm aware I might have to use attachElements, and several other functions. For the moment, I'd like to attach a single wheel. I've got this: -- All GUI elements. local vehicle = getPedOccupiedVehicle(localPlayer) local x1, y1, z1 = getVehicleComponentPosition(vehicle, "wheel_lf_dummy") local x2, y2, z2 = getVehicleComponentPosition(vehicle, "wheel_rf_dummy") local x3, y3, z3 = getVehicleComponentPosition(vehicle, "wheel_lb_dummy") local x4, y4, z4 = getVehicleComponentPosition(vehicle, "wheel_rb_dummy") local function replace1 () attachElements (1097, vehicle, x1, y2, z1, 0, 0, 0) end addEventHandler ("onClientGUIClick", set1, replace1, false) -- Function runs when button called 'set1' is clicked. -- Everything else. Here's my thought process: First, I get the player's vehicle. Then, I get the position of all four wheels in the player's vehicle, and represent them with x1, y1 and z1. With all wheels hidden by another function, I then attach the wheel model in the same place as the front left wheel. At the moment, I'm only aiming at the position; I'll handle the rotation later. DB 3 can't identify '1097', and thus asks for a valid element. Am I on the right path?
  6. This is in 1440x900 (in my resolution): This is in 1920x1080: I calculate the dx elements position with this: local sx_, sy_ = guiGetScreenSize() local sx, sy = sx_/1440, sy_/900 And i draw dx elements like this: dxDrawRectangle(sx / 2 + 290, sy / 2 +240,850,65,tocolor(0,0,0,200)) What wrong??? How can i fix this problem??
  7. Hi. I have a problem, that whoever is online on my server, sees edit boxes, that should only appear to who clicked a button (i use localPlayer), and it simply just appears for the ones who already passed the login panel. Pieces of scripts: (Client and serverside) Client: function loginButton_Click() loginUsernameText = guiGetText (loginUsername) loginPasswordText = guiGetText (loginPassword) triggerServerEvent ("attemptLogin", localPlayer, localPlayer, loginUsernameText, loginPasswordText) end Server: function attemptLogin(element, accountname, password) local q = exports.db:sqlQuery ("SELECT * FROM users WHERE accountname = '"..accountname.."' AND password = '"..md5(password).."';") local result = dbPoll(q, -1) if #result > 0 then for k, v in ipairs(result) do triggerClientEvent ("outputAccountMessage", element, "Successful login!", "information") setElementData (element, "logged", true, true) triggerClientEvent ("destroyEdits", element) setElementData (element, "id", v['id'], true) setElementData (element, "admin", v['admin'], true) setElementData (element, "aduty", v['aduty'], true) setElementData (element, "anick", v['anick'], true) setElementData (element, "banned", v['banned'], true) setElementData (element, "accountname", v['accountname'], true) local q = exports.db:sqlQuery ("SELECT * FROM characters WHERE owner = '"..getElementData(element, "id").."';") local result = dbPoll(q, -1) if #result > 0 then for k, v in ipairs(result) do setElementData (element, "hud", true, true) setElementData (element, "characterChosen", true, true) spawnPlayer (element, tonumber(v['posX']), tonumber(v['posY']), tonumber(v['posZ'])) fadeCamera (element, true) setCameraTarget (element, element) showCursor (element, false) showChat (element, true) setPedArmor (element, v['armor']) setElementHealth (element, v['health']) setElementInterior (element, v['interior']) setElementDimension (element, v['dimension']) setElementData (element, "name", v['name'], true) setElementModel (element, v['skinID']) setElementData (element, "anick", v['anick'], true) setElementData (element, "aduty", v['aduty'], true) dbFree (q) end else setElementData (element, "characterChosen", false, true) triggerClientEvent ("characterCreationMenu", element, element, v['accountname']) end end else triggerClientEvent ("outputAccountMessage", element, "Login failure!", "error") end dbFree (q) end addEvent ("attemptLogin", true) addEventHandler ("attemptLogin", root, attemptLogin) I mean for example edit boxes will appear to every if localPlayer's account has no character that is owned by his account id. And at the call of "destroyEdits" the editBoxes will get destroyed for everyone who has visual on the login panel. What did i screw up?
  8. Working on a First Person Shooter gamemode, and i found a bug. The event onClientPreRender causes some delay at attachElements. Can somebody reproduce attachElements maths for me?
  9. http://imgur.com/a/og3e5 this is the problem, how to fix this? code: local screenW, screenH = guiGetScreenSize() addEventHandler("onClientRender", root, function() local x, y, z = getElementPosition(localPlayer) local location = getZoneName ( x, y, z ) dxDrawImage(screenW * 0.0076, screenH * 0.7300, screenW * 0.2194, screenH * 0.2422, "mapbg.png", 360, 0, 0, tocolor(255, 255, 255, 255), false) dxDrawText(location, screenW * 0.0965, screenH * 0.7370, screenW * 0.2250, screenH * 0.7567, tocolor(118, 224, 90, 255), 1.00, "default-bold", "left", "center", false, false, true, false, false) end ) addEventHandler("onClientResourceStart", getResourceRootElement(getThisResource()), function () setPlayerHudComponentVisible( "area_name", false ) end) local sx, sy = guiGetScreenSize() local rt = dxCreateRenderTarget(290, 175) local xFactor, yFactor = sx/1366, sy/768 local yFactor = xFactor function findRotation(x1,y1,x2,y2) local t = -math.deg(math.atan2(x2-x1,y2-y1)) if t < 0 then t = t + 360 end; return t; end function getPointFromDistanceRotation(x, y, dist, angle) local a = math.rad(90 - angle); local dx = math.cos(a) * dist; local dy = math.sin(a) * dist; return x+dx, y+dy; end function drawRadar() showPlayerHudComponent("radar", false) if disableGTASAhealth then showPlayerHudComponent("health", false) end if disableGTASAarmor then showPlayerHudComponent("armour", false) end if disableGTASAoxygen then showPlayerHudComponent("breath", false) end if (not isPlayerMapVisible()) then local mW, mH = dxGetMaterialSize(rt) local x, y = getElementPosition(localPlayer) local X, Y = mW/2 -(x/(6000/worldW)), mH/2 +(y/(6000/worldH)) local camX,camY,camZ = getElementRotation(getCamera()) dxSetRenderTarget(rt, true) if alwaysRenderMap or getElementInterior(localPlayer) == 0 then dxDrawRectangle(0, 0, mW, mH, 0xFF5E656B) dxDrawImage(X - worldW/2, mH/5 + (Y - worldH/2), worldW, worldH, "image/world.jpg", camZ, (x/(6000/worldW)), -(y/(6000/worldH)), tocolor(255, 255, 255, 255)) end dxSetRenderTarget() -- dxDrawRectangle((10)*xFactor, sy-((200+10))*yFactor, (300)*xFactor, (200)*yFactor, tocolor(0, 0, 0, 175)) dxDrawImage((10+5)*xFactor, sy-((200+5))*yFactor, (300-10)*xFactor, (175)*yFactor, rt, 0, 0, 0, tocolor(255, 255, 255, 255)) (this not the full code)
  10. Hello, I am creating a PIN system on my server and wanted to ask you for help in my code. When I send the client to the server a trigger wanted to validate if the pin sent from the client to the server is an element of my table if yes setElementData will work and the Pin used will be unable to use again but in my script when it uses a pin all The others are disabled, can you help me? Note: I'm Brazilian, I'm sorry for English. local pins15k = {"UAIFKAJDKEFC15K", "KYJFKAJDEFKC15K", "BESFKSLLKEFC15K"} function PinEdit(Pin) if validatePin(Pin) then if getElementData(source, "Diamond") then setElementData(source, "Diamond", getElementData(source, "Diamond")+10000) else setElementData(source, "Diamond", 10000) end for k, v in ipairs(pins15k) do outputChatBox("["..k.."] = "..v) end else outputChatBox("Pin invalido", source) outputChatBox(tostring(pins15k)) end end addEvent("PinEdit", true) addEventHandler("PinEdit", getRootElement(), PinEdit) function validatePin(pin) local result = false for k, v in ipairs(pins15k) do if (pin == v) then pins15k[k] = nil result = true break end end return result end
