construct arrays are actually 3 dimensional, so the array represented as json looks like this
{
"c2array": true,
"size": [
1,
1,
1
],
"data": [
[
[
"stuff"
]
]
]
}
you would need to do something like this
+ System: On start of layout
-> Array: Set value at 0 to "{""enemies"":[2,2], ""position"":[1,2], ""wait"":[0,0]}"
notice you have to escape the double quotes
