I have some World Gen in my world, and I'm using a Tick Handler to implement a structure that tells me to place things in IWorldGen.  However, because of how the Tick Handler works, the first couple dozen chunks around spawn are generated before the Tick Handler creates my Gen structure. Everything else is generated fine, but there is an empty circle around spawn. Is there a way I can respawn these chunks after my structure has been initialized? Or even better, is there a way to initialize a class on World Load before any chunks get generated?

Umm, TickHandler for WorldGen? You are doing something wrong

You might want to look at the IWorldGenerator interface.

 

Bad wording on my part! I use IWorldGenerator for actually placing my blocks and things, but I have a method that tells me where to place them.  And this method is unique for each world.  Thus, it need to be initialized every time the World Loads, which is where the tick handler comes in.  I would do it another way if I could, but I can't think of any other way to gen a unique structure for each world. 

 

But back to my original question.  Is there a way to force regenerate chunks? Or, even better, find a hook that will initialize this structure before anything is generated.
