ios - Rotate SCNNode to face point -

-

i'm trying rotate object (scnnode) face point it's moving. move across x , y axis, far tried:

    // action move node     let action1 = scnaction.moveto(scnvector3(x: 4.0, y: 0.0, z: 6.0), duration: 3)     // tan angle:     let angle = cgfloat(atan2(z, x))     if angle - previousangle > pi {         playerangle += 2 * pi     } else if previousangle - angle > pi {         playerangle -= 2 * pi     }     previousangle = angle     playerangle = angle * rotationblendfactor + playerangle * (1 - rotationblendfactor)     let rot = playerangle - 90 * degreestoradians     flynode.rotation = scnvector4(x: 0, y: 1, z: 0, w: float(rot))

it works target points not all.

i try add constraints array scnlookatconstraint, rotates node perfectly, stop move animation:

    let targernode = scnnode()     targernode.position = scnvector3(x: -4.0, y: 0.0, z: -2.0)     let con = scnlookatconstraint(target: targernode)     flynode.constraints = [con]             let action1 = scnaction.moveto(scnvector3(x: 4.0, y: 0.0, z: -2.0), duration: 3)

can me out wit this, please?

the easiest solution, though perhaps not elegant, apply moveto scnaction node, , apply scnlookatconstraint child of node. should enable both operate without conflict.

ios - RestKit 0.20 — CoreData: error: Failed to call designated initializer on NSManagedObject class (again) -

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
