GUI Stops showing when calculations too large?

[DtrollMC]

Hey guys, so I'm messing around with 2D arrays and simple terrain generation algorithms. I know that the two algorithms I wrote are not very efficient, but I have gotten the results to display under certain settings. However, when I try to increase the size of the matrix I am generating / displaying, all the steps are done but the GUI just never shows up. What could be causing this?

 

The source code is only a few classes, so it won't take long to check out. Don't judge the code too much as I just refactored how the UI was structured so things are still messy.

Anything with size > 200 doesn't appear.

I don't know the language you're using but a general problem with GUI solutions is the program tying up the main thread so it cannot handle events, that results in a "program not responding" or the GUI not showing up.

 

Try doing the actual work in a new thread so the main thread can keep on doing the message pump.

I will look into that. Haven't done any multi-threaded programming before. Using Kotlin

Never heard of Kotlin before but you could always write the array into a bitmap very easily to view the terrain as a height map.
