How do for-in loops in swift work? -


i've used them, i'm familiar code , read number tutorials still don't understand how work in can't run through head i'm doing , want achieve, opposed if statement can read in english quite well.

for-loops have been i've struggled through lack of understanding, can offer insight please?

the for-in loop performs set of statements each item in range or collection. swift provides 2 range operators a..<b , a...b, shortcut expressing range of values.

// prints 1-10 in 1...10 {     print(i) }   // way has been removed in swift 3 use above var = 1; <= 10; i+=1 {     print(i) }

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
