if that should be :
addEventHandler("onPlayerSpawn",getRootElement(),
function()
local vehicle = getPedOccupiedVehicle ( source )
vehicles = {602, 545, 496, 517, 401, 410, 518, 600, 527, 436, 589, 580, 419, 439, 533, 549, 526, 491, 474, 445, 467, 604, 426, 507, 547, 585,
405, 587, 409, 466, 550, 492, 566, 546, 540, 551, 421, 516, 529,513, 581, 510, 509, 522, 481, 461, 462, 448, 521, 468, 463, 586, 485, 552, 431,
438, 437, 574, 420, 525, 408, 416, 596, 433, 597, 427, 599, 490,528, 601, 407, 428, 544, 523, 470, 598, 499, 588, 609, 403, 498, 514, 524,
423, 532, 414, 578, 443, 486, 515, 406, 531, 573, 456, 455, 459, 543, 422, 583, 482, 478, 605, 554, 530, 418, 572, 582, 413, 440, 536, 575, 534,
567, 535, 576, 412, 402, 542, 603, 475, 568, 557, 424, 471, 504, 495, 457, 483, 508, 571, 500,
444, 556, 429, 411, 541, 559, 415, 561, 480, 560, 562, 506, 565, 451, 434, 558, 494, 555, 502, 477, 503, 579, 400, 404, 489, 505, 479, 442, 458}
local randomindex=math.random(1,#vehicles)
local vehicleid=vehicles[randomindex]
setElementModel ( vehicle,vehicleid )
end)
then it aint working
