ha sorry for my english.

is for paint one sprite on foreground or background of other sprites depending of the location of sprite on map.

in iso map this :

hello,

I search a speed sorted paint algorithm for my group of sprites.

have you a example or tips ?

thank you

Ok sorry now i have my degree with your solution :

int rotateAngle=(int)java.lang.Math.round(java.lang.Math.atan2(((pointTwoX - pointOneY)) , ((pointTwoY - pointOneY)))*360/java.lang.Math.PI);

now i can test the angle for choose good animationStrip for my sprite !

my code is good or have you a more speed solution ?

Thank you captain.

ok and i trie this :

i don' t compile with atan2:

int rotateAngle=(int)java.lang.Math.round(java.lang.Math.atan2(((double)(pointTwoX - pointOneY)) / ((double)(pointTwoY - pointOneY))));
       
because atan2 take two double in parameter .

with atan compile but the result is not my solution :

int rotateAngle=(int)java.lang.Math.round(java.lang.Math.atan(((double)(pointTwoX - pointOneY)) / ((double)(pointTwoY - pointOneY)))*180/java.lang.Math.PI);

       
you have the same example with atan2 ?
thank you very much

hello ,

I search how to obtain degree information from two location of point in my applet for ordinal direction for sprite .

I trie :

public class Angle {
   
   int pointOneX = 100;        // ->
   int pointOneY = 100;        // v
   
   int pointTwoX = 90;        // ->
   int pointTwoY = 58;        // v
 
   double distanceX = 0;
   double distanceY = 0;
   double distance = 0;
   
   public Angle() {
       
       calculDistance();
       calculAngle();
   }
   
   private void calculDistance() {
       
       distanceX = pointTwoX - pointOneX;
       distanceY = pointTwoY - pointOneY;
       
       distance = Math.sqrt(distanceX * distanceX + distanceY * distanceY);
       
   }
   
   private void calculAngle() {
       
       double startAngle = (int)Math.toDegrees(Math.asin(distanceY / distance));

           System.out.println(" startAngle : " + startAngle);
       
   }
       
   public static void main(String[] args) {
       
       new Angle();
   }
   
}

but the result is not very helpfull.

have you a solution ? thank you very much
