So I’m trying to make a small adventure mode for my game, and I need to be able to store the information when a level is completed. I am trying to use a PrintWriter, and it actually prints the right result into a text file, but when the game restarts the line gets deleted which is against the whole …

Okay I just realised that it’s probably smarter to use the saveString function, since it saves the lines forever, but they are still being overwritten. (Oh yeah and I haven’t even gotten to the load Function, but maybe I’ll understand that one.)

Usually you would keep the whole content of the file in memory. When you want to save it, overwrite the whole file with a new file with saveStrings(). When you want to load it, load the whole file with loadStrings() and then access individual lines.

I think saving works now, but I have trouble loading the files. When I type in: String[] levelProgress = loadStrings("C:\Users\name\Documents\Processing\Space_Invaders\levelProgress.txt"); it gives me the error message: Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \\ ) I’m actual…

Thanks @GoToLoop , but I was rather looking for a solution that I can also understand at my current level :sweat_smile: Looks like I have it now anyways :stuck_out_tongue:

Okay so I have another question… What does the loadStrings function do exactly? I ask this because I’m loading the text file into the levelProgress String[], but it doesn’t really get the value. But on the other hand, it looks like it does…? :sweat_smile: When I print out the value of the first vari…

Thanks, I didn’t know about that :smile:
