Yes, they are predefined.
I thought about loading them via JSON but it doesn't give me the structure i need.
(the debugger shows 10 values in the array but they are all 0)
The output should allow me to do the following;-
index = random number from 1-10
array[index][0 for x position]
array[index][1 for y position]
then i can delete that array index so its not used again.
[EDIT]
I have solved my own question with the above reply.
Set Value at (0,0) to 60
Set Value at (0,1) to 150
Set Value at (1,0) to 60
Set Value at (1,1) to 265
etc
I just need to do that for all ten positions.
