generate in another thread
i'm doing the calculation on the thread but i can't place by thread
there will be empty places and sometimes the game crash

What do u mean can’t place the thread?
Offloading the work to another thread and maybe making the chunks smaller are the only real options you got i think

i made the thread place the areas but look what i get
even in small chunks it make them (20x20)
when i use the main thread to place everything in it place but it need to freeze for at least 20ms

Maybe share ur code? Its weird that it would stutter for such small operations, we would need some more details

here is the code thata generate the world
well chunks i did shrink the size to make it match
for now i'm using a button to make the world but it freezes a little like i said
if you the action of the button is what makes it freeze i was planning on make it automatic tmrw

There a few problems i think, i will give a detailed response in a few hours if i am behind my pc, if no one else has by that time

okayy htanks in advance *

So, am not gonna lie the part where you calculate the grid where you want to place new tiles is confusing me and I hope it is just a chunk of 20 tiles insteald of recalculation everything but if it is, then you are doing double operations on :
if n >= 0.1 :
_grass_array.append(cell)
if n >= 0 and n <= 0.2 :
And
if n >= -0.2 and n <= 0.1:
_sand_array.append(cell)
if n <= -0.2 :
_water_array.append(cell)
if it's -0.2, even though this isn't that costly, in terms of optimization it doesn't make sense.
In the end the biggest cost will come from apply_tiles, where you are placing tiles, this is still being done on the main thread
