Here is an example of a CSV:
CSV,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20
First,1,2,1,1,1,0,1,2,2,0,3,0,2,0,0,1,1,1,2,12
Second,2,2,0,1,2,1,1,1,2,1,1,0,2,3,3,3,1,2,2,0
Tirth,0,0,1,0,0,2,1,0,3,1,3,0,2,1,3,2,3,0,0,0
Fourth,1,0,3,1,3,2,0,2,3,2,3,1,0,2,1,0,2,3,2,0
Fifth,0,0,0,1,2,0,1,1,0,1,2,0,1,0,2,2,0,3,3,0
The idea is to spawn that amount of fireball at Y (100, if in the first line, 200 if in the second, 300 thirth, 400 fourth, 500 fifth) at every 2 seconds, for example. This is done, let's say, 40 times at the first stage and 60 at the second.
Please tell me if my question is clear enough.
