I’m stuck
on growBtn pressed do
(
i = 0
log.Caption = "Loop starting..."
total = selection.count
p = 0
for s in selection do
(
i = i+1
obj = instance pickBtn.object
theMod = SpacePathDeform()
thePath = getnodebyname selection[i].name
addModifier obj theMod
theMod.path = thePath
obj.transform = thePath.transform
p = i / total * 100;
progressBar.value = p;
lastObjects[i] = obj.name
obj.parent = thePath
--append lastObjects obj
log.Caption = "Iteration: "+i as String+" done..."
)
theObj = pickBtn.object
theObj.renderable = false
theObj.xray = true
log.Caption = "Done! Picked is not Renderable now!"
)
p stays at 0 until the loop is finished. Thought if I put i or total into the log output – those values are changing.
I think it is something really simple, but I can’t find the reason.
Thanks!
look at your code again… you need the variable i to be float just only to calculate right value for a progress bar. in the text expression “Iteration: “+i as String+” done…” where a float doesn’t make sense…
so you shouldn’t make the i float. you just have to write correct expression for the progressbar value…
you have:
i = 1
count = 2
p = i / total * 100
this expression returns an integer because all arguments are integers.
you can make any argument a float and it changes the return value to float.
i – is innumerate index – makes sense to stay integer
count – good to be number as well
so … 100 is your client
but if change to:
i/count*100.0
it will make a float, but it will be wrong result because int/int gives int. so… just change the order of your arguments:
i*100.0/count
-- or 100.0*i/count
You are dividing an integer by a biger integer ( i / total). As a result you get 0.
Try this:
total = selection.count as float
or
i = i+1.0
A useful trick is to times the first number by 1.0, this is useful when you’re dealing with variables and don’t know if you’re getting floats or integers.
5 / 2 = 2
2 / 5 = 0
1.0 * 5 / 2 = 2.5
1.0 * 2 / 5 = 0.4
