CreateObject

Creates an object element at a given position and rotation.

[[{{{image}}}|link=|]]	Note: Dynamic objects do not automatically have physics applied to them. Use setElementVelocity(object, 0, 0, 0) to fix this.

[[{{{image}}}|link=|]]	Note: The alternative createBuilding function allows you to create objects that are non-dynamic. This createObject function can also create non-dynamic objects, but for optimization reasons it is recommended to spawn Buildings when creating static objects in the Dimension 0 (because they don't use the MTA object-streaming system).

Syntax

object createObject ( int modelId, float x, float y, float z, [ float rx, float ry, float rz, bool isLowLOD = false ] )

OOP Syntax Help! I don't understand this!

Method: Object(...)

Required Arguments

• modelId: A whole integer specifying the GTA:SA object model ID. See Object IDs for a list of model IDs.
• x: A floating point number representing the X coordinate on the map.
• y: A floating point number representing the Y coordinate on the map.
• z: A floating point number representing the Z coordinate on the map.

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

• rx: A floating point number representing the rotation about the X axis in degrees.
• ry: A floating point number representing the rotation about the Y axis in degrees.
• rz: A floating point number representing the rotation about the Z axis in degrees.

• isLowLOD: A bool value specifying if the object will be low LOD. A low LOD object has no collision and a longer draw distance.

Returns

• Returns the object element if the creation was successful, false otherwise.

How to automatically perform object/building creation

This example shows you how to automatically create an object or building element according to certain parameters.

This script onlys works CLIENTSIDE due to createBuilding and engineGetModelPhysicalPropertiesGroup.

-- Creates an 'object' or 'building' element based on certain parameters or one of the functions fails
-- This function will throw an error when unexpected arguments are used
-- TODO: Add LOD support
function createObjectOrBuilding(modelID, x, y, z, rx, ry, rz, interior, dimension)
    -- Validate the arguments passed
    assert(type(modelID)=="number", "invalid modelID passed: " .. tostring(modelID))
    assert(type(x)=="number" and type(y)== "number" and type(z)=="number", "invalid position passed: " .. tostring(x) .. ", " .. tostring(y) .. ", " .. tostring(z))
    if not rx then rx = 0 end
    if not ry then ry = 0 end
    if not rz then rz = 0 end
    assert(type(rx)=="number" and type(ry)== "number" and type(rz)=="number", "invalid rotation passed: " .. tostring(rx) .. ", " .. tostring(ry) .. ", " .. tostring(rz))
    if not interior then interior = 0 end
    if not dimension then dimension = 0 end
    assert(type(interior)=="number" and interior >= 0 and interior <= 255, "invalid interior (must be 0-255) passed: " .. tostring(interior))
    assert(type(dimension)=="number" and dimension >= -1 and dimension <= 65535, "invalid dimension passed (must be -1 65535): " .. tostring(dimension))

    -- Dynamic object models will always have a physical properties group different than -1.
    local isNonDynamic = engineGetModelPhysicalPropertiesGroup(modelID) == -1
    -- Buildings can't be affected by dimension
    local isNormalDimension = dimension == 0
    -- Buildings can't be placed outside regular map boundaries
    local isInsideMapLimits = x >= -3000 and x <= 3000 and y >= -3000 and y <= 3000

    local obj, bld
    if isNonDynamic and isNormalDimension and isInsideMapLimits then
        bld = createBuilding(modelID, x, y, z, rx, ry, rz, interior)
        assert(bld, ("Failed to create building with model ID %d at %f, %f, %f in interior %d"):format(modelID, x, y, z, interior))
    else
        obj = createObject(modelID, x, y, z, rx, ry, rz, false)
        assert(obj, ("Failed to create object with model ID %d at %f, %f, %f"):format(modelID, x, y, z))
        setElementInterior(obj, interior)
        setElementDimension(obj, dimension)
    end
    return obj or bld
end

-- Test this create object/building function
addCommandHandler("testobject", function()
    -- This would be your object's model ID
    local modelID = 3556
    -- This would be your object's position coordinates
    local x, y, z = 0, 0, 69
    -- This would be your object's rotation coordinates
    local rx, ry, rz = 0, 0, 90
    -- This would be your object's interior ID
    local interior = 0
    -- This would be your object's dimension ID
    local dimension = 0

    -- We use pcall to catch any errors that may be thrown
    local success, element = pcall(createObjectOrBuilding, modelID, x, y, z, rx, ry, rz, interior, dimension)
    if not success then
        outputDebugString(("Failed to create object or building: %s"):format(tostring(element)), 4, 255, 25, 25)
        return
    end

    -- OPTIONAL: Then you can apply additional properties, like so:
    if getElementType(element) == "object" then
        setObjectScale(element, 1.69)
        setObjectBreakable(element, false)
    end
    setElementAlpha(element, 255)
    setElementCollisionsEnabled(element, true)
    setElementFrozen(element, false)
end)

Server-only Example 1

This example creates an object when the resource starts:

function loadMapObjects()
   -- create an object at a specified position with a specified rotation
   createObject(1337, 5540.6654, 1020.55122, 1240.545, 90, 0, 0)
end
addEventHandler("onResourceStart", resourceRoot, loadMapObjects)

Server-only Example 2

This example creates an object near the player who write /createObject in the chat:

-- this function is called whenever someone types 'createObject' in the console:
function createObjectCommand(thePlayer, commandName)
   if (thePlayer) then
      local x, y, z = getElementPosition(thePlayer)
      -- create a object next to the player:
      local theObject = createObject(980, x + 2, y + 2, z, 0, 0, 0)
      if (theObject) then -- check if the object was created successfully
         outputChatBox("Object created successfully.", thePlayer)
      else
         outputChatBox("Failed to create the object.", thePlayer)
      end
   end
end
addCommandHandler("createobject", createObjectCommand)
