java - Direction from origin for a certain distance -


I want to push a crowd from a direction to a certain distance, I right click on the crowd, but when I This code uses the distance to remove the crowd, depending on how close or far I am to the crowd. 

  target.motionX = (target.posX- player.posX) * 0.5; Target.motionZ = (target.posZ - player.posZ) * 0.5;

I know that the direction I face is needed to get that direction, then the crowd should take it away from a certain distance. I do not know how to do this.

Firstly you will need to find the distance: 

  float xDis = target .posx - player.posX; Float zDis = target.posZ - player.posZ;

If xDis is zero, calculate angle: 

  float tangent = zDis / xDis; Float angle = Math Space (tangent); After that, set the length of your throw vector:  
  float length = 0.5;  
 
 and then projection on two axes: 
 
  float express = length * Math.cos (angle) * math. Signum (xDis); Boat zProj = length * Math.sin (angle) * math. Signum (xDis);  
 
 And these are your  motionX  and  speed  parts. 
 
 If  xDis  is   zero, then I think that you will need this special case. 
 
  float xProj = 0; Boat zProj = length * math. Signum (zDis);

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
