There are two ways for placing items:
Placing them directly:
Place ItemSpawn for randomization:For ItemSpawn:
Don't forget to set which items your level can have (and how many!):
Now you have some options for an ItemSpawn:GenerateAlways
puts the Item in the "important" list, these items will be generated first. This is only really important if you want "advanced" item generation (but to be safe, you can of course just tick it - it doesn't hurt).random item
does what it says. If you tick this, the ItemSpawn will select a random item from its list to use (otherwise the first one).
Every ItemSpawn has a pool of items that COULD spawn (although not the same item twice on the map AFAIK). random item
also automatically adds the level's item pool (screenshot #3) to this item's pool, which means that you can just always check "random item" for your items and they should appear (you don't have to use the "add Item" menu).
