Get the blocks in between set coordinates and the player?

I was wondering if anyone knew how to get the types of blocks in between the player and a set value of coordinates? I'm not sure if this has been covered in a thread before and if it has then this can be a more updated thread than an older one.

Thanks!

Like a cuboid selection?

 

Like a straight line if thats possible....?

Between the player's location and 1 coordinate?

 

For example if the player was at 100, 60, 200 (x, y, z) and the set coordinate was at 200, 60, 200 I would like to get the blocks in between.

 

RandomGuyDom Create a for loop that increments x each time, get the location, and do whatever it is you want to do to the block.

 

Triple nested for loop through each coordinate x, y, and z.
