This is me again, reviving one more time, so please forgive me everyone, and ASHLEY. But a very important part of the game I am working on is closely related to this subject, so it could be nice to know the priority of this subject. If it's very low priority, I will have to re-work the entire digging system to something else. I have left the digging part in hopes of this coming but other parts are almost done and I will have to tackle digging soon so...
Basically, I have to use huge layouts (as big as 25k x 25k) and a grid based obstacle system to create a maze like sturcture, which is dynamic and changes during gameplay. Regenerating entire obstacle map pauses the game for a second, sometimes more. It breaks the game as it is now.
Please forgive for reviving twice in a row...
regards;
