I generally use 'feel and 'engage to control things independently in
View. ie...
counter: 1
view layout [
b1: box
b2: box rate 10 feel [engage: [
; This is executed 10 times a second. See 'rate in the
; previous line.
b1/color: random 255.255.255 show b1
if counter [
counter: counter + 1
if counter > 5 [
counter: 1
b2/color: random 255.255.255 show b2
]
]
]]
button "Stop" [counter: none]
button "Start" [counter: 5]
]
HTH.
