Possible to change BlockNames after release?

[TeNNoX]

I would like to change the block names to something more unique because they were called something like "normal" or "corner" or "cross" in 1.6.4 and this is pretty bad for 1.7.4 I think.

 

Is there a way to change those without being unable to load older worlds?

 

PS: Is it right that there would be a conflict when another mod would call it's blocks "normal" or "corner etc., or isn't it?

When you register blocks and items through GameRegistry, the modid is automatically added to the name like:

modid:datAwesomeBlock

Unless you also choose a stupid modid (like "mymod" or "test"), you should be fine.

There are different names. There is the Icon Name, the Block registered name, and the unlocalized name. Each has a different purpose. There is even a display name. Which are you trying to change?
