This function will smoothly move an object from its current position to a specified rotation and position.
Syntax
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 ] )
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 function to use for the interpolation (default is "Linear")
- fEasingPeriod: the period of the easing function (only some easing functions use this parameter)
- fEasingAmplitude: the amplitude of the easing function (only some easing functions use this parameter)
- fEasingOvershoot: the overshoot of the easing function (only some easing functions use this parameter)
Returns
Returns true if the function moved the object succesfully, and returns false otherwise.
Examples
Example 1: This example moves every object in the game up 100 units in ten seconds.
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
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.
-- Find a player called 'someguy' someGuy = getPlayerFromName ( "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) <syntaxhighlight lang="lua"> local START_POS = {2497.203125, -1672.4864501953, 12.640947341919} local STOP_POS = {2480.2595214844, -1666.521484375, 12.640114784241} local MOTION_DURATION = 5000 local WAIT_DURATION = 1000
addCommandHandler("smove", function (player, cmd, strEasingType, period, amplitude, overshoot) local x, y, z = unpack(START_POS) local object = createObject(1598, x, y, z) x, y, z = unpack(STOP_POS)
period = period or 0.3 amplitude = amplitude or 1.0 overshoot = overshoot or 1.70158
outputChatBox(string.format("Server Easing %s %s %s %s", strEasingType, tostring(period), tostring(amplitude), tostring(overshoot))) moveObject(object, MOTION_DURATION, x, y, z, 0, 0, 360, strEasingType, period, amplitude, overshoot) setTimer(destroyElement, MOTION_DURATION+WAIT_DURATION, 1, object) end)
Example 4: This example move gate with easing.
local x,y,z = 2096.3, 1721, 12.7
local easing = "OutBounce"
local time = 2000
local gate = createObject(980, x,y,z, 0, 0, 63)
local marker = createMarker(x,y,z, "cylinder", 12, 0, 0, 0, 0)
function moveGate(hitPlayer, matchingDimension)
moveObject(gate, time, x+4.9, y+9.6, z, 0, 0, 0, easing)
end
addEventHandler("onMarkerHit", marker, moveGate)
function moveBack()
moveObject(gate, time, x, y, z, 0, 0, 0, easing)
end
addEventHandler("onMarkerLeave", marker, moveBack)
