Hey guys

function removeModels() 
removeWorldModel(985, 10, 2497, 2773, 10) 
removeWorldModel(986, 10, 2497, 2773, 10) 
removeWorldModel(7172, 100, 2577.7, 2825, 15) 
removeWorldModel(961, 100, 2577.7, 2825, 15) 
removeWorldModel(960, 100, 2577.7, 2825, 15) 
removeWorldModel(3474, 100, 2577.7, 2825, 15) 
removeWorldModel(3269, 500, 230, 2502, 15.-- s8) -->
removeWorldModel(3270, 500, 230, 2502, 15.-- s8) -->
removeWorldModel(3271, 500, 230, 2502, 15.-- s8) -->
end 
addEventHandler ( "onResourceStart", getRootElement(), removeModels ) 

and

LSbase = createColRectangle ( 2602, -2705, 208, 110) 
function clearBases() 
    LSvehicles = getElementsWithinColShape(LSbase, "vehicle") 
    for theKey,theVehicle in ipairs(LSvehicles) do   
        health = getElementHealth(theVehicle) 
        if health < 30 then 
            destroyElement(theVehicle) 
        end 
    end 
end 
setTimer ( clearBases, 5000, 0 ) 
  
SFbase = createColRectangle ( -2497, -1831, 280, 500) 
function clearBases() 
    SFvehicles = getElementsWithinColShape(SFbase, "vehicle") 
    for theKey,theVehicle in ipairs(SFvehicles) do   
        SFhealth = getElementHealth(theVehicle) 
        if SFhealth < 30 then 
            destroyElement(theVehicle) 
        end 
    end 
end 
setTimer ( clearBases, 5000, 0 ) 
  
LVbase = createColRectangle( 2475.3491210938, 2606.2819824219, 294.8916015625, 341.60009765625) 
function clearBases() 
    LVvehicles = getElementsWithinColShape(LVbase, "vehicle") 
    for theKey,theVehicle in ipairs(LVvehicles) do   
        LVhealth = getElementHealth(theVehicle) 
        if LVhealth < 30 then 
            destroyElement(theVehicle) 
        end 
    end 
end 
setTimer ( clearBases, 5000, 0 ) 
  
function unBlock() 
setTimer ( destroyElement, 30000, 1, source ) 
end 
addEventHandler ( "onVehicleExplode", getRootElement(), unBlock ) 

Please Help me thanks!
