Javascript alternative for arrays within arrays


I just discovered that unity that doesn’t support arrays within arrays, a feature I really liked in flash for things like tilemaps etc.

Is there a good alternative in unity?

What I want to do is creating an obstacle spawnsystem for an infinite runner game, which should work like this

array = [[obstacle 1, time till next obstacle gets spawned],[obstacle 2, time till next obstacle gets spawned],[etc., etc.]]

then there should be a random selection between these obstacle arrays to have a nice mixture of a designed levels with a random factor in it.

If you have a good idea how to do this with unity, i’m all ears.



Unity does support arrays in arrays. For a tilemap, however, you’d use a 2D array.
