Spawned objects and gravity

[AcidbRain]

I have this piece of code running client-side:

local x, y, z = getElementPosition(getLocalPlayer())
local boulder = createObject(1303, x, y, z + 10)
setElementVelocity(boulder, 0.0, 0.0, -0.1)

The fact is that the spawned boulder doesn't fall to the ground, even with my attempt to nudge it with setElementVelocity (which, by the way, returns true).

What else can I do?

Something has to hit it iirc. Do something cool like spawning an invisible dozer on top of it, that should make it roll.

Not exactly what I was hoping for, but that's a great idea nonetheless.
