Eng:Distance to () (block)

The Distance to  block is a Sensing block and a Reporter block. The block reports the distance (a measurement of pixels) between it and a specified sprite's costume center, or the mouse-pointer.

Example Uses
As this block can give distances between objects, it is very useful in projects that require a great deal of careful sensing and movement.

Some common uses for the Distance to block: if <(distance to [snowball v]) < (40)> then say [Watch out!] wait until  say [] //stop saying the message set [movements v] to ([ceiling v] of ((distance to [meteor v]) / (10))) //"movements" being the amount of 10 pixel motions to reach the meteor set [real distance v] to (join ((distance to [asteroid v]) * (10000)) [ kilometers]) //for relating pixel distance to real life
 * Estimating when collisions will occur
 * Helping determine how long it should take a sprite to move somewhere, judging from the distance
 * Determining how far a rocket should fire

Workaround
This block can be replicated with the following code: ([sqrt v] of ((((x position) - ([x position v] of [Wanted Sprite v])) * ((x position) - ([x position v] of [Wanted Sprite v]))) + (((y position) - ([y position v] of [Wanted Sprite v])) *((y position) - ([y position v] of [Wanted Sprite v])))))

Related Suggestion
Some Scratchers want a block that gives the distance to any location, not just a sprite. It would be like this:

(distance to x: y: )//category=sensing

It is technically unnecessary because it can be replicated with a similar workaround:

([sqrt v] of ((((x position) - (wanted x)) * ((x position) - (wanted x))) + (((y position) - (wanted y)) * ((y position) - (wanted y)))))
