Kheyre, sometimes in order to appropriately help with a problem, you need to gather more details, otherwise you end up giving a solution to an irrelevant problem.
If he means item wrench spawns (as opposed to throwing an item or something) you can package the ItemData::onAdd() method like so:
package ItemPosition
{
function ItemData::onAdd(%this,%obj)
{
%obj.setTransform(vectorAdd(%obj.getTransform(),"0 0 5 0 0 0 0"));
Parent::onAdd(%this,%obj);
}
};
activatePackage(ItemPosition);
For example, the above code would position all items 5 units above where they would normally spawn.
