Explanation needed (and some GM help)

(In General) What are arrays, how are they used, and where are they useful?

(Specific) how would one use them in Game Maker?

[fruckert]

Arrays are a type of variable.
I honestly don't know the technicalities behind it, but it basically makes it so that the specific variable has different indices.
To make an array, do this:
variable[0]
variable[1] (bracket's are important)
They're often used to cut down on how many variables you have, as Game Maker, specifically, has a tendency to delete variables when they're not being called at that moment, causing humongous glitches in step events.
You can use them for damn near everything.
I personally use them for stats, or having different timers in things.
Just experiment, and see what you come up with.

"indices"?

I'm sorry, i still dont quite get it.

[fruckert]

Index's.
It's basically storing a bunch of mini-variables inside of one variable.
So then:
global.roomnext[0] can = "room0"
and global.roomnext[1] can = "room1"

[Vlad Shadeu]

How do i set an individual mini-variable and how do i call a specific mini-variable?

[fruckert]

Same as a variable.
Just get the variable (vari) and add a bracket with a number in it (vari[0]) in the create event.
As far as I know though, you can only use the ones you call.

[Vlad Shadeu]

Oh yeah, do you think you could do a little bit on the TACT engine? Just enough to get people interested.

[fruckert]

Sorry, not at the moment.
As I've mentioned before, too busy.

[Vlad Shadeu]

Okay then.........
