[General] two jass questions

[Chaosy]

1. I have seen a few scripts using private nad public stuff is that a big deal? example why use private integer i insted of integer i. also public integer must be the most pointless line ever since it's allready global no need to make it public? (if it aint a local variable ofc)

I know that a private only works within the block but when is that something importment?

2. can i set loop speed into jass? Id want something like

loop 1.00
exitwhen i = 10
set i = i +1
endloop

that would be supposed to loop every second (1.00) is there something like that in jass or do I need to use a loop event for that?

You might not want to allow users to modify values outside of the library/scope/struct. For example you might have a projectile flying, and it has speed variable. You might not want to people to meddle with the speed so you set it to private.

2. can i set loop speed into jass?

Use a timer.

1. indeed but I would say the user shold have full controll over the spell/system but I wont debate about it

2. sad that there is no easier way.

About making variables private, it's more for preventing name collisions. A variable named speed is likely to be declared by multiple resources so instead of wasting time thinking of a new name, you make it system's private.
Public variables have scope prefix that also prevents name collisions and makes the variable identifier unique yet usable outside of scope.

exitwhen i = 10

This is a syntax error.

You need to do

exitwhen i >= 10

Reals are not absolutly accurate so you need to allow for errors so == is not recomended with them except when comparing constants.
