hi,i have a for next loop that randomly positions my trees,rocks,etc on my island.

my problem is dbp is always positioning too many objects in the center of my island together.i have randomize at the beginning of my code.this is a problem because when my player gets to this area,frame rate drops considerably.

anyone know how i can reposition these bunched up objects away from each other??

Break your island up into smaller chunks, and randomise the placement within those chunks. That way no 'chunk' can ever have too many objects in it.

Move a random distance in the X..repeat..Drop down in the Z, and keep doing that, making sure that the minimum distance in the X is not too close to a tree.

He didn't mean break up the island literally! He meant just break it up logically into squares and place a certain amount of each object in each sqaure.

Spooky speaks wise words I did mean that.

Say your island is 1000x1000 in size and you want to place 100 items.

Instead of picking a random number between 1 and 1000 - break it down into chunks 250 in size. So you'd place 25 items between 1,250. Then another 25 between 251,500 - etc until you've covered the whole island.

Then no one area can have more objects than another.

ok,ill try that.but im not sure how to keep the objects inside a specific box.the way i did it for my whole island was to make another check to see if any objects were past the x,z of the island & to delete them if they were.

Here's some simple code that splits an island up into equal sections. I have set 'split' to 4 which means split island up 4 times across and 4 times down, basically giving 16 sections. Then a couple more variables saying I want between 1 and 3 trees per section. Change the variables and you get different results.

The only thing missing is some distance code to stop you placing trees on top of each other.
