{{Server client function}}
__NOTOC__
This function will smoothly move an object from its current position to a specified rotation and position.

==Syntax==
<syntaxhighlight lang="lua">
bool moveObject ( object theObject, int time,
float targetx, float targety, float targetz,
[ float moverx, float movery, float moverz,
string strEasingType, float fEasingPeriod, float fEasingAmplitude, float fEasingOvershoot ] )
</syntaxhighlight>

===Required Arguments===
* '''theObject:''' The object that will be moved.
* '''time:''' The time in milliseconds the object will arrive at the destination.
* '''targetx:''' The X value of the target position
* '''targety:''' The Y value of the target position
* '''targetz:''' The Z value of the target position

===Optional Arguments===
* '''moverx:''' The rotation along the X axis '''relative''' to its current rotation, which is its starting angle.
* '''movery:''' The rotation along the Y axis '''relative''' to its current rotation, which is its starting angle.
* '''moverz:''' The rotation along the Z axis '''relative''' to its current rotation, which is its starting angle.
*'''strEasingType:''' the [[Easing|easing function]] to use for the interpolation (default is "Linear")
*'''fEasingPeriod:''' the period of the [[Easing|easing function]] (only some easing functions use this parameter)
*'''fEasingAmplitude:''' the amplitude of the [[Easing|easing function]] (only some easing functions use this parameter)
*'''fEasingOvershoot:''' the overshoot of the [[Easing|easing function]] (only some easing functions use this parameter)

===Returns===
Returns ''true'' if the function moved the object succesfully, and returns ''false'' otherwise.

==Examples ==
<section name="Server" class="server" show="true">
'''Example 1:''' This example moves every object in the game up 100 units in ten seconds.
<syntaxhighlight lang="lua">
allObjects = getElementsByType ( "object" )
for key, theObject in ipairs ( allObjects ) do
local origX, origY, origZ = getElementPosition ( theObject ) --get the origanal position
local newZ = origZ + 100 -- make a new z position
moveObject ( theObject, 10000, origX, origY, newZ ) --move the object to this position in 10 seconds.
end
</syntaxhighlight>
</section>

<section name="Server" class="server" show="true">
'''Example 2:''' This example created a model (of a bed) near a player called ''someguy'', if they exist in the game. It will then move the model towards the player over 3 seconds.
<syntaxhighlight lang="lua">
-- Find a player called 'someguy'
someGuy = getPlayerFromNick ( "someguy" )
-- If a player called someguy was found then
if ( someGuy ) then
-- Get the player's position
x, y, z = getElementPosition ( someGuy )
-- Create a bed (1700) object near to the player
bed = createObject ( 1700, x + 5, y, z )
-- Move the bed towards the player over 3 seconds (3000 milliseconds)
moveObject ( bed, 3000, x, y, z )
-- Tell the player in the chat box
outputChatBox ( "Moving a bed towards you!", someGuy )
else
-- Tell everyone that a player called 'someguy' could not be found
outputChatBox ( "Player someguy doesn't exist" )
end

'''Example 3:''' This example creates a ball moving (in front of CJ's house in Grove Street) using easing functions. Test command is "/smove" for instance "/smove OutBounce". This example is a serverside code but the same could be done clientside (adapting the command handler)
