I'm really banging my head on how to keeping items shown or hidden, like one might find in Nethack or the Mystery Dungeon series. Essentially: everything the player has actually been near is revealed, all else is hidden. I can't figure it out.

The key is significant to the operation I'm doing. It is a unique ID that is generated elsewhere.

This is a lua question, but I assume it will be of use to new love2d people, also. In PHP (the language I am most familiar with) I can, for example, create an multidimentional arrays like this: array[1]['field'] = "a value" , and then simply refer to it as array[1]['field'] in order to get...

The Wiki helped, specifically this:

Code: Select all

-- Initialize the pseudo random number generator
math.randomseed( os.time() )
math.random(); math.random(); math.random()
-- done. :-)

Calling math.random() 3 or 4 times before I actually need it seems to give me the results I need. Very weird.

I get the same result: 8, every single time running it via the Love executable in OS X and Windows XP. On OS X I just double click test.love, on windows I click and drag test.love (which contains the main.lua file posted by nunix) onto the Love.exe. 8 every time.

I am wondering if this is possibly an OS X issue? Both nunix and I are running Mac OS X 10.5 intel.

"seeming" random .vs. "being" random seems to be at issue, here. Getting numbers that "seem more random" is definitely a desirable goal, but how to accomplish it?

I'm working on a roguelike engine using love2d, and I'm really hitting a wall with lua's math.random() function to get, you know, random numbers. The first thing I did was try os.time() as my randomseed, but that kind of falls apart when you are hitting it multiple times within one second ( using th...
