[...]so we can prevent entities from landing inside a block in the first place.

You really can't - the player can place a block into a place where a pickup is, and the server needs to deal with it.

It might be easier to write a function that would return the nearest "available" space, and direct the entity towards it. Using NY-metric for "nearest" should be sufficient, to make the search algorithm easier.

how to spawn pickups[...]?

In C++ we have the cWorld::SpawnItemPickups() functions; they are not exported into Lua API, not sure why. I think they should work out of the box. Try auto-exporting them to API and use them.

Exporting is done by putting

Code:

// tolua_begin

above the function declaration and then

Code:

// tolua_end

after the function declaration (in the .h file; there are several exported functions so have a look at those); then running the AllToLua script in the Source folder (it will generate the bindings into the Bindings.cpp file)
