Hi, Gravity Games here, and I'm working on a simple platform game for android. Unfortunately however, I'm having trouble implementing a level format that spawns objects. I'm trying to read a .txt file, then write integers into an arraylist, and finally using the appropriate line in the array for a variable in the object (x and y position, and later on which graphic file it uses)
Here's what I've got:
gameView:
Tile:
and here's the error I keep getting:
Here's what I've got:

Happens all the time, no worries.
