HIVE

Sure thing. You don't have to ask for help, write down your questions immediately.

I felt that would have been quite bossy and unpolite.

Well, I need:
-Different regrowing times for different kinds of trees.
-No revival as long as there are units walking on top of them.

Thanks for your help.

There first one is easy, but the second one is entirely different thing - i.e. should not be a part of that system, but instead a customization.

To implement the first, one can use hashtable for saving respawn timers for each destructable-id separately. Before starting regrow timer, check if such value exists for given destructable-id. If not, fall back to default regrow delay.

Second one is trickier. I.e. you would have to specify a "collision size" of a destructable i.e. area which given tree occupies and needs no units inside to be regrown. Each time a periodic timer elapses and system is about to regrow a tree, check for existence of unit objects within nearby area given the collision size. If at least one is found, this means that timer should be restarted and attempt again in the future.

I can help with coding if you are not sure how to proceed with this one. I might also be updating my TreeRevival this weekend, so our goals align.

Then I'm in my lucky week! I'll wait for your update before deciding what to do next.

Thanks again.

Delayed due to amount of requests ppl threw at me : )
I'll look into it either today evening or tomorrow. Don't think I've forgotten : )

How familiar are you with vJass? Asking in case I'd like to provide solution in vJass.

I'm afraid I'm a GUI peasant with no (v)Jass knowledge at all.

Just take your time, my friend. This is far from being an emergency.
