"Islands" not being generated after certain x/y value

Post by BlueThumbDevelopment » Sat Feb 02, 2019 4:20 pm

So I've been messing around with island generation and i do have on that works. However if I try and generate an island after certain x and y values it says it generated but does not draw on screen? I do not know if I have accidentally made a limiting factor for x/y values perhaps?

Feel free to request code or have a look at the code (generation is in noise.lua)

I've tried to fix this for god knows how long and I'm in need of help :3

Are you maybe drawing outside the 5000x5000 canvas? I don't see any other limits in the code.

The # operator isn't guaranteed to work unless the arrays start in 1. I think LuaJIT is more forgiving about not starting exactly with 1, but not as much as 1000 times more forgiving.

The problem seems to be in the iteration limit for the drawing loop. Changing it to this worked for me:

Code: Select all

                for x = island.x, island.x + size do
                        for y = island.y, island.y + size do

Okay pgimeno, I'll give it a try in the morning! Thanks for giving me a hand 😀
