=== Next\r
-* Continue making the scripting system:\r
- * Make updateNodeMesh for a less verbose mesh update on add/removenode\r
- * Switch to using a safe way for the self and env pointers\r
- * Make some global environment hooks, like node placed and general\r
- on_step()\r
+* Make a system for pregenerating quick information for mapblocks, so\r
+ that the client can show them as cubes before they are actually sent\r
+ or even generated.\r
\r
=== Fixmes\r
