Detect Game Version

[cristimirt]

Hi. Simple question, not sure if simple answer as well. How can we detect the game version? I'm interested in detecting if it's pre-4.0 or 4.0+.

You want it not without a reason. So the reason will give you the answer.

Say, if you want to know if it has a certain function to use it, or not, just check if that function does exist.

if common.MyUsefullFunction then
DoStuff()
else
DoOtherStuff()
end

But if the function does not exist, won't it give an error? Getting an error everytime you load the addon will make the mod.txt pretty big with time.

Checks if that function exists or not. If not - it will return nil which is same as false to "if" function, so the code after "then" will not be executed, else will trigger instead.

Here's an example:

Once upon a time a function common.GetLocalTime() was moved to mission.GetLocalTime().

Here's how to fix that:

if common.GetLocalTime then 
mission.GetLocalTime = common.GetLocalTime
end

So if you use this script in a 4.0.0 - it will work with no common.GetLocalTime at all. And if you run this in an older version, it will create mission.GetLocalTime and mission.GetLocalTime in your script will work as common.GetLocalTime does.

You may download SetMyFPS and look at first couple of lines. I think you'll understand how does that work.

Ooo.. I get it now Thanks. And yes, reading the code for SetMyFPS also helped
