Posted September 5, 20187 yr What would be the best method of notifying players of a null pointer exception caused by an improperly edited .cfg file without closing the game? I'm currently using a try catch expression to avoid crashes, but I'm unsure of what method is standard practice for notifying users.

Letting the game crash. VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect. Forge and vanilla BlockState generator.

Wouldn't it be better to send a client side chat message to the player once they log in/when the mod loads, use ConfigChangedEvent.OnConfigChangedEvent to detect a change in the .cfg filess and reload them using ConfigManager.sync(TestMod3.MODID, Config.Type.INSTANCE) so players don't have to reload the game every time they make a mistake?

Something went wrong. Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice. Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked. DO NOT PM ME WITH PROBLEMS. No help will be given.
September 5, 20187 yr Author Even in cases like changing block hardness where the game would still run fine even if it wasn't changed? NOTE: Block hardness is just an example, this is for the whole Block Health thing. Edited September 5, 20187 yr by 1SDAN
September 6, 20187 yr A null value can be valid but if you're getting an actual null error then you're usually doing something wrong in your code. For example, you've mentioned reading a config file and getting a null value. Well, first of all your file parsing should handle the case of non-exiting keys/value without really going null but if it does go null then just check for null value before trying to use it. In other words, a null pointer exception happens when you USE the null value, so you can always check for null before the possible use of it.
