The point in direction () block is a stack block and a Motion block. The block points its sprite in the specified direction, rotating the sprite. The blocks use the 360 degrees in a circle. The default value is 90 and can be replaced by any Number (360+x displays the same than 0+x). When the input is clicked, a circle appears where one can select a direction.
There has been some confusion involving the number system due to the fact that 0 is straight up, rather than off to the right (the default direction) or off to the left (as in a protractor), and that it uses a -180 to 180 circle rather than a normal 360 degree circle. Despite complaints,[1] no changes have been made.
Prior to Scratch 3.0, this block had a dropdown in addition to the input for degrees, which looked like this: point in direction ( v)
Example Uses
If a sprite must be turned and its direction is not known, this block can be used.
Some common uses for the point in direction () block are:
- Flipping a sprite:
when I receive [flip v] point in direction ( ( direction ) - ( 180 ) )
- Choosing where a cannon points:
point in direction (answer)
- Pointing vehicles towards a destination
point in direction (wanted destination)
Workaround

The blocks can be replicated by turning the needed number of degrees:
turn right ( ( wanted direction ) - ( direction ) ) degrees turn right ( ( wanted direction ) + (360) ) degrees
