Thanks for finding that i'll give it a go! :D
found the roving patrols also
// add some random patrols on the island
// if the array is empty, no patrols
// same size like a rectangular trigger
// first element = center position, second element = a, third element = b, fourth element = angle, fifth element = number of groups
d_with_isledefense = [[6592.61,8606.63,0], 6000, 6000, 0, 4];
