Small values for setSize() of clones may not work properly i.e. if setSize(value) is less than 40? Clone does propagate but behaviour is erratic.
Example:
Alien.whenReceiveMessage('Start', function(){
Score = 0
this.hide()
this.setSize(40) // but if setSize(30) then irratic behaviour
x = -210
y = 120
// make a total of 32 clones
for (var counter1 = 1; counter1 < 5; counter1++) {// make 4 rows of clones
for (var counter2 = 1; counter2 < 9; counter2++) {// make 8 coloumns of clones
this.clone()
console.log('create clone')
this.wait(0.25)
x = x + 60
}
y = y - 70
x = -210
}
console.log('finished making clones')
})
