Removing objects from table

[rob]

It should be local screenGroup = self.view

tmp.someMethod(someParam) does not pass a reference (self) to the object to the method, only the specified parameter.  tmp:someMethod(someParam) does pass the object in as self.  tmp:someMethod( someParam ) is identical to tmp.someMethod( tmp, someParam) in calling and internally if you use : you don’t have to specify self, it’s there automatically.

Ed, I’m not sure what’s up with your posts getting mixed in out of order.

Also, keep in mind that if you do indexed arrays, if you nil out a member in the middle, the # operator only counts up to the first nil:

t = {  2, 3, 5, 8, 9, 1, 4, 6 }

print(#t) – outputs  8

t[4] = nil

print(#t) – outputs 3

You need to use table.maxn() to loop over a numerically indexed table with nil’s in the middle.

Hey there !

Just tried your code, and in both cases, outputs 8… Is is normal ?

Interesting.  This used to be an issue.  It doesn’t seem to be an issue now.
