Randomizing Objects in Different Rooms

How do I make it so in every room, there are different chances (or equal chances) of different objects spawning in. Like rocks, sticks, leaves, etc. And a maximum to how much spawns in a room at once. Trying to best to avoid Libraries.


The first.

firsttime {
  SpawnZombie (this)
}

You can also do it with attributes, but it's trickier.

if (game.spawn = 2) {
  SpawnZombie (this)
}
else {
  msg ("...But nothing came.")
}

Ugh... What?


I think Empherdaen wants each room to have its own random "window-dressing", i.e., random stackable crafting objects for the player to collect. I haven't dealt with cloning, so am not equipped to advise about that.


Right you are Dcoder.


Hey again Enpherdaen here is the first part in that same series https://www.youtube.com/watch?v=BUGNbe2--Yk it shows how to make randomized room spawner for items.


Oh, very sorry. I misunderstood the question. I have reading difficulties, if you haven't noticed.


No problem Jmnevil54. Thanks Onimike.


Here is one way to do it...
I have a Split variable that contains the index list of room descriptions.
that is then randomized.
Then the rooms are numbered 1 through 20
That way, the 5th entry in the list is the description for room #5
Then a switch to select which room description to show.
The same could be used to random items, one to a room.
You could also use a for loop to seed stuff in each room.

(filler for getting my edited post, updated/posted)


here's an example:

(not fully complete, some more error and exception handling can be added to the 'spawn_data_object.set_spawn_script_attribute' as I got tired, and can still be refactored/stream-lined/improved further such as reducing some code redundency via using Delegates with the Script Attributes, and the code logic/design itself can probably be done better too)
