Proper location iteration. Possibly math related.

Hello.
I need to create particle effects in a straigt line. I already know how to display the particle effects (using packets) but using BlockIterator makes it not look very good when not looking in a straight line. I need it to work like this:
As you can see, it goes in a perfect line.

Thank you.

 

Maybe a vector using target block and eye location?

 

Have you even tried using the search function? The amount of times I have personally answered this questions is way to high and I know others have done the same.

Basic trig and location add methods. Doing something similar, haven't tested yet however.

Doing what i found in one of your other posts made it go per block, like from x0.0 to 1.0 but doing that vertically gives it some really hard corners.

Great, if you figure it out could you come back at me?

 

qlimax5000 So something like this ?

Code:java

 
void playEffectsInLineOfSight(Player player, double spacing, double distance) {
  Location nextLoc = player.getEyeLocation();
  Vector step = nextLoc.getDirection().normalize().multiply(spacing);
  double distanceLeft = distance;
  // this does not start directly in the players face but 1 step further
  while ((distanceLeft -= spacing) > 0.0D) {
    nextLoc.add(step);
    playEffectAt(nextLoc);
  }
}
 
void playEffectAt(Location loc) {
  // put your effect creation code here
}

Works great, thanks
