[1.7.10] How to detect whether a player is looking at a block.

Hi, sorry I posting so late at night (If your on Mountain Time) but I have a few problems. Problem #1) I would like to know to detect if a player is looking at my custom block. Problem #2) I would like to draw some quads (I know how to do that) and make them rotate depending on the direction the player is looking. Like barriers (I know that's in 1.8 and uses particles, but that's besides the point).

 

Is there any way to do this? If so how? Could anyone point to some good tutorials, if any?

Problem #1) Which block you are looking at, try this:

 

MovingObjectPosition mop = Minecraft.getMinecraft().objectMouseOver()

 

or you could try rayTracing, but i'ts proven to be a bit inaccurate over long distances.

Problem #2) Get the players looking vector, you could look at the code for the enchanting table, the book does something similar.

I require Java, both the coffee and the code :)

Ok, but how do I get the look angles from a Vec3 (where the player is looking)?

Ill just send you a bit of code that I use whenever I get home.

 

I know this is an older thread, but mind sharing that code with everyone if you can? I'm trying to solve this same problem.
