Some of you, who probably don't read this forum, already know that I'm teaching myself C++. My efforts, however, have hit a snag.

I've set up an array that holds 10 random values; I want to use those numbers in a function as seeds for my randomized levels, but I can't figure out how to tie the array in to the level generator.

I've attempted to use pointers, but I'm not sure they'll do what I want, and I don't know how the heck they work anyhow :)

Is there a kind soul out there that can shed a light on things for me? :)

That sounds like regular C stuff, not even C++.

You can address the specific cell of the array. Let say you have declared an array called TestArray:
int TestArray[10]={3,4,7,9,8,etc};
So later when you need a value stored in specific cell of the array, you just call for that cell. Example:
TestArray[0] is the very first cell, it contains 3.
TestArray[1] contains 4.
TestArray[2] contains 7.
etc.

Okay! So, I'd just put TestArray[0] in the CreateRoom function?

if you put testArray[0] it will only pick the value of the FIRST index.. in the example above.. it will pick 3..

are you trying to use all the values in the array? then you will need to use something else to pick the values in the array.. The most common is a loop.

From your first description, it sounds like all you want is to use a random number generator.

i think a more elegant solution is to create a random number generator function, and whenever you need a random number generator, just call that function.. that way you can ignore dealing with array indexing in that specific part of the code.

Then the CreatRoom function will use the value stored in the TestArray[0] cell.

I've got the PRNG working. I'm just trying to store the level seeds when the game starts, so that I can create ten levels and go back and forth through the array.

Okay, let's say you have an array "seeds", and you want only the one room's seed to be passed to the room generator. Let's call this room index variable "x". To get the specific seed for room x, you'd use "seeds[x]" which gets the seed at position X. for all practical purposes you can treat that entire little phrase as a variable, meaning you can assign to "seeds[x]", do math with it, or pass it directly to a function that accepts a [whatever the array type is] like this: "GenerateRoom(seeds[x])".
