[Vector Math] Getting the block the player is looking at with precise collision point

Hi !

The goal of this is to play an effect, in a line, from where the player is lookin at to a point, and this is already done:

Code:

Vector bulletVector = GunMechanic.getShootVector(p, getRange());
       
        // calculating the locations
        Location begin = p.getEyeLocation();
        Location end = p.getEyeLocation().toVector().add(bulletVector).toLocation(p.getWorld());
       
       
        Block target = p.getTargetBlock(null, getRange());
        if(target!=null) {
            p.getWorld().playEffect(target.getLocation(), Effect.STEP_SOUND, target.getTypeId(), 3);
        }
        GunMechanic.effectLine(Effect.PARTICLE_SMOKE, begin, end, 20);

However, this aways draws the effect at maximum range.

I can detect the block the player is lookin at and set the end position to it, but it will tweak the line a little bit to fit integer values of the block zyx while the vector draws precisely with double values.

So i need to know , the exact collision point that the player eye vector has with a block so i can do a precise draw of the particle effect line.

Does anyone knows how to perform this ?

Thanks alot in advance.

 

You can do something like this

Code:java

Location loc = player.getLocation();
loc.add(loc.getDirection().multiply(10));

Gets the exact point the player is looking at 10 blocks away. You could just increment the value.

Code:java

// Vector bulletVector = GunMechanic.getShootVector(p, getRange()); - I don't know what this is
 
// calculating the locations
Location begin = p.getEyeLocation();
Location end = begin;
double range = getRange();
while(!end.getBlock().getType().isSolid() && end.distance(begin) < range) {
end = end.add(p.getLocation().getDirection().multiply(.1));
}
 
// I didn't change anything below this
Block target = p.getTargetBlock(null, getRange());
if(target!=null) {
p.getWorld().playEffect(target.getLocation(), Effect.STEP_SOUND, target.getTypeId(), 3);
}
GunMechanic.effectLine(Effect.PARTICLE_SMOKE, begin, end, 20);[FONT=Georgia][/FONT]

I'm not really sure what bulletVector was, so I ignored it. I also assumed getRange() was a double.

If you have any questions about it, or my assumptions were wrong, tell me.
