# Trouble with chosen random numbers

• 4 posts
• I am creating a air plane cargo and delivery game with exploration to find more airports.

You start with 3 airports , if you are at airport 1 it will give you passengers and cargo for airport 2 and 3 --choose(2,3) nice and easy

if you are at runway 2 you can only get passengers and cargo for airports 1 and 3 -- Choose(1,3)

now while exploring you may find another airport to add to list this could be runway 4 or 5 or 6 or 7 and so on

as you can see i cant just add a ,4 to the choose command as it may be airport 6 i find first so i need to add the 6 if i find runway 6

for about 6 airports i could probably do all combinations of the choose to sort this but i am going to have about 30 airports

so i need to add say runway 15 only if i find it

So is there a way that i can alter my choose line to add a number to a ready made choose line

Choose(2,3) as ma at runway 1 i fly off and find runway 7 and when i do make the choose line choose(2,3,7) then i find runway 5 choose(2,3,7,5)

i hope this is easy to understand. HELP WOULD BE MOST APPRECIATED

• I've done this before with arrays, when a runway becomes available you push the number to an array. I set the variable to always choose something that is available inside the array so set the number to array.at(random(0, array.width)) will pick a random value that exists, such as 0,1 0,2 0,3 0,4 in the array.

So at the start you push 2 and 3 to the array. These would be at 0,1 and 0,2. When you come across 7 you push that to the array so 0,3 is 7 and the array looks like this (2,3,7). Then using array.at(random(0,array.width)) it will set the variable to a random number in the array, either 2, 3 or 7. Hopefully it's easy to understand the approach I was taking.
