Every time I get close to catching up, a new part releases! I look forward to following along with this one soon, too. Thank you!

As always nice and informative. Remember to dispose of Graphics2D object when you are done drawing to the BufferedImage(image), since you are creating Graphics2D g2 = image.createGraphics(), unless you dispose it, the resource will stay open. Its something that's easily forgotten.

I'm always so excited when i see a new video on your channel!

Hey, Ryisnow! I was looking back and wondered if it was possible to add interactive tiles on the map to avoid confusion. Thanks!

Wow cant wait to make my own game to enjoy

[ProjCRys]

how do you include the other entities such as NPCs and objects into the map? because if I wanted to display a map with abundance of objects the map looks desolated when it only displays the tiles.

So when I try to start the game after implementing the map for the first time, it crashes and sends this error: Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
I think it's cause my map is too large, cause when I shrink it down it works fine. Right now my map is 341x193. Do you know any way to fix this without changing the map size?

YAY THANKS!


If anyone has added new tilesets/maps I Was running into issue where I would get a :

Cannot read field "image" because "this.tile[tileNum]" is null
at
at tile.Map.<init>(Map.java:17)
at
at main.Main.main(Main.java:17)

Took me a second to figure out, but it was because I still had old maps that were not being used with old tilesets but I had not commented/deleted them out yet. Once I commented it worked just fine again.
