How to draw polygon with radius around polyline in ios swift -


i have problem drawing polygon around polyline(( have coordinates polyline , want buffer coordinates coordinates of polygon around polyline.

i have this: enter image description here.

but want make this:

enter image description here

please help...

you can draw 2 polylines same path.

let's you've created variable thepath buffered coordinates. you've created polyline path. 

let redpolyline = gmspolyline() redpolyline.path = thepath redpolyline.map = mapview

create one.

let redpolyline = gmspolyline() redpolyline.path = thepath redpolyline.strokewidth = 6.0 // change accordingly  redpolyline.strokewidth = uicolor.redcolor().colorwithalphacomponent(0.5) // change accordingly  redpolyline.map = mapview

remember redpolyline's zindex should higher bluepolyline because can see in image you've provided, redpolyline on top of other one.

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
