Not really. You've kinda mixed a few concepts up. To put it simply;
'For' is used for 'for-next' loops, which generally look like this in C#:
- Code: Select all
for (int t = 0; t < Insert Value Here; ++t)
Insert Code Here
Which simply starts at zero, runs Insert Code Here and loops and increments t until its equal to Insert Value Here, at which point the for-next loop ends.
'float' is a decimal value. It's used to declare your algebraic letter(s) as a decimal value. ('int' is an integer; it's used to declare that something doesn't have decimals).
'Something.SubSomething' is used when you have a value that has sub-values. That's a whole topic on its own. Basically, you used this correctly, save that sub-values are always typed (That is declared float, integer or some other type of value) in the main value.
Anyway, that's it from off the top of my head.
