[SOLVED] Question about Logging

[Armetron]

Hey guys

 

So I'm slowly but surly making my mod by following every kind of tutorial I can find, however in many example codes I find I see something called a logger mixed into the code. After doing some research I found out that this part of the log4j api which basically responsible for printing all the text in console when you boot up an instance of forge (INFO, ERROR, ext...) which is something I find very useful and probably better than using println()

 

however despite all these examples that have loggers placed in them I cant seem to find out how modders are actually using them.

 

I followed McJty's Basic Mod - 1.9 tutorial and added logger = event.getModLog() into my preInit and included org.apache.logging.log4j.Logger but now I dont know how to use it, or if I even need to use it

 

does anyone have any experience with loggers or is this something I shouldn't worry about? if this is something worth using are there any tutorials regarding it? (didn't seem to find any here)

Can't you do logger.print or something like that?

You can use Logger#info, Logger#debug, Logger#warn, etc. quite easy. So what is your problem? Referencing?

There's also Logger#log(Level,Message)

well what my problem is in how to actually use it, for example in my CommonProxy file I have within the preInit "ModBlocks.init();" and "ModItems.init();" which loads all my stuff, I would l to print to console using the logger "Loading *my mod's* blocks" then "Done Loading *my mod's* blocks" that way if any errors happen with loading all I have to find are those two blocks of text

 

to do this would I just have to type

Logger#info("Loading " + Reference.MOD_ID + "'s Blocks")

No, java won't understand something like '#' there.

You should get the logger and call the method of it named 'info'. (It was what I meant by 'Logger#info)

welp It seems I need to go back to Java class because the solution to my problem was rediculasly easy to fix, I read that I had to use logger.info("string") for it to work but every time I tryed to use it on a file that wasn't the mod file I couldn't get it to work

 

turns out I forgot that I dont have to type logger.info(), I have to type *mymodfile*.logger.info(). I actually feel a bit of shame for not realizing that sooner

 

Thanks anyway you guys

"Logger#info" means you need an object of Type "Logger" and you need to invoke the method "info" on it.  In your other files you tried doing just "logger.info(string)" but that didn't work because you didn't have an object of Type Logger in that scope.

 

So yeah, this was one of the more painful things I've read on this forum in a while.
