Get the block(or blocks nearby is ok) which player is looking at

[zerozhou]

I've known how to get the entity which the player is looking at through the implementation of the enderman... But how can I get the "block" far far away(maybe within a range) which the player is looking at?  Do something do this in minecraft(like get entity being looked at in enderman's code)? Or someone could give some ideas about doing this?

Probably not since nothing in Minecraft would use it.

 

You can use the "look" vector (math is required ) from the player and its position to check blocks in a straight line, and stop when said block isn't air.

Hmm. I've thought about the idea you said. Actually I'm seeking for a more beautiful way to do this as dealing with math is not a quite happy thing right? :-) Thanks any way.

This is the most efficient way (without editing the EntityPlayer).

You'll always find math at some point in your code
