Random Array from anything?

[Sartan]

lets say i have... a integer with 7 arrays called:
int[0, int[1]...int[6]
how do i "pick" a random int[x] of these, without being able to pick the same int twice?

 

[Trollvottel]

first fill the fields:

var[1] = X
var[2] = X
var[3] = X
var[4] = X
var[5] = X
var[6] = X

get a new variable called i, its an integer and has the value 6

loop
now get a random int between 1 and i and call it r.

save the value of var[r] in tempvar
now just set var[r] to var
reduce i by 1.
endloop

tempBoolean is type "Boolean" with initial value of False
tempBoolean2 is an Array with a size of 7 and of type "Boolean" with initial value of False.
RandomInt is type "Integer" with initial value of 0

• Custom script: loop
  • Custom script: exitwhen (udg_tempBoolean == true)
  • Set RandomInt = (Random integer number between 0 and 6)
  • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
  • tempBoolean2[RandomInt] Equal to False
  • Then - Actions
  • Custom script: set udg_tempBoolean = true
  • Set tempBoolean2[RandomInt] = True
  • Else - Actions
  • Custom script: endloop

This was done free hand, if you'd like to know where to put your actions at to make this work for your game, feel free to PM me. And I'll make it look neater. (I'll make it JASS too.)

plz make a more JASS loking example
and trollvotel, how is your trigger working? is it removing the int that is picked or?

 

[Trollvottel]

yes thats right, its just picking one and setting the last int in this list to this position. kind of permutation i think.
the example by failenx just picks a random slot until it hits a free slot. that can work, but it could also go horribly wrong, remember the random numbers in warcraft III are not really random...
well i dont think i have to make a jass example, the code is not too complicated and you can learn by doing

 

[Sartan]

dont worry i can do the basic thing as this myself if i know how to do
