[1.6.4]Finding what the player is looking at

[AskHow1248]

Hi everybody.  I need to find what the player is looking at (block or entity).  I know somewhere in the Minecraft source code it does it (eg. when the player mines something) but I don't know how or where.  I was thinking something along the lines of using player.getLookVector().normalize() and extending it through a for loop until it hits something, but it seems like there must be a better way.  Any help will be appreciated, especially the location of the code Minecraft uses to do the same thing.

Hi

 

The information about what the player is currently looking at is stored in Minecraft.objectMouseOver.  See Minecraft.clickMouse().

 

It is updated in EntityRenderer.getMouseOver.  You have the right idea, actually the vanilla code does pretty much exactly that.
