Battle Royale Loot Spawner (Tutorial or Example Proj)

Do you guys know any good online tutorials for battle royale weapon spawning systems? Same as Pubg or Fortnite’s spawning system (randomized weapon spawning when entering level with probability or weight for items to spawn, etc). Been looking for a while and can’t find anything…

Can you explain a bit more on what you need precisely?
Those systems are rather straightforelward but always completely custom since it is something purely based on what logic YOU as the end user want to use…

The base concept is, define spawn points, define spawn rates, use a random value to make it happen.
