Get Block in Front of Entity

I want to have an entity moving and any blocks in its way are set to air.
How would I go about getting the block in front of the moving entity (like an arrow)?

 

What about using "getTargetBlock" on Living Entities for this?

I said like an arrow, not a living entity.

 

You could calculate the direction of the arrow by getting the yaw and then add distance to the arrow's location accordingly (lets say the yaw is 5 then you could calculate that the block in front of it is +1 on, lets say, x and then set the material of the block to air).

 

its some

Code:java

EntityArrow a;
a.getLocation().getBlock();

thing like:

 

This will not be easy. You basically gotta calculate where the arrow will fly, and therefore which blocks it flies through and then replace them with air. There is no EntityMoveEvent, sorry.
