[1.7.10] What event is called when a new chunk is created

[Nt..]

What event is called when chunk is generated for first time?

[Draco18s]

Also keep in mind that there are other mods out there that modify a chunk long after its been generated.  COG, for example, waits until the next chunk over is modified so that it can go in and clean up any coal that bleeds over before placing ores using its own algorithms ("deferred generation +16"; "deferred +32" would be two-chunks-over, etc. although nothing uses anything later than that by default).

 

So yeah, depending on what you're doing, the right place to sit and wait for an event might change.
