So I've been trying to make a triple shot bow/gun and I need to find a way to move the arrows a bit to the left/right (+/- 1 to the x) based on the position of the center arrow

Here's my current code:

#

Vector arrowDirection = player.getLocation().getDirection();

                    Entity arrow = player.getWorld().spawn(player.getEyeLocation().add(arrowDirection), Arrow.class);


                    Entity arrow2 = player.getWorld().spawn(player.getEyeLocation().add(arrowDirection).add(1,0,0), Arrow.class);
                    Entity arrow3 = player.getWorld().spawn(player.getEyeLocation().add(arrowDirection).add(-1,0,0), Arrow.class);```
                                                                                                                                                                                                              ^  this part needs fixing ^

mmm wouldnt you want to use the player's Y and Z? - me goes to check add. for vectors

what is not working right now?

leaden parcel what is not working right now?

it works good but only when im facing the right side of the world in game

#

on certain sides it just shoots 3 arrows in one spot (not spreading them)

leaden parcel Mar 17, 2022, 6:15 PM

#

I see

#

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Location.html#setYaw(float) would this work?

#

doesnt getEyeLocation only return the level of the eyes and not the direction?

agile lark Mar 17, 2022, 6:17 PM

#

im using eyelocation to get the direction the player is looking at, then adding one block forward so the arrows dont spawn in the players head and hurt it

leaden parcel Mar 17, 2022, 6:17 PM

#

Another solution would be to use

Entity arrow2 = player.getWorld().spawn(player.getEyeLocation().add(arrowDirection).add(0.5,0.5,0.5), Arrow.class);
Entity arrow3 = player.getWorld().spawn(player.getEyeLocation().add(arrowDirection).add(-0.5,-0.5,-0.5), Arrow.class);

instead

#

Actually if you shoot diagonally that won't help either

amber jungle Mar 17, 2022, 6:18 PM

#

but you are not using the Location with yaw and pitch ...

leaden parcel Mar 17, 2022, 6:18 PM

#

now that should help

leaden parcel Mar 17, 2022, 6:18 PM

#

amber jungle but you are not using the Location with yaw and pitch ...

why would you want to?

amber jungle Mar 17, 2022, 6:18 PM

#

the other doesnt return direction

leaden parcel Mar 17, 2022, 6:18 PM

#

The pitch/yaw is inherited from the player's pitch/yaw

agile lark Mar 17, 2022, 6:19 PM

#

yaw and pitch are weird sometimes and they cause performance issues so i just avoid using them

leaden parcel Mar 17, 2022, 6:19 PM

#

Oh, the player would damage itself there

amber jungle Mar 17, 2022, 6:20 PM

#

also without pitch wouldnt the two extra arrows go flat instead of up/down ?

leaden parcel Mar 17, 2022, 6:20 PM

#

Either you slightly nudge the pitch/yaw or you change your 1 block offset to be based around the pitch yaw, however at that point you still get the sin/cos calls

leaden parcel Mar 17, 2022, 6:20 PM

#

amber jungle also without pitch wouldnt the two extra arrows go flat instead of up/down ?

pitch is interhited from the player

agile lark Mar 17, 2022, 6:21 PM

#

^ i want the arrow

amber jungle Mar 17, 2022, 6:30 PM

#

leaden parcel pitch is interhited from the player

i see it now, its a different one for head height.

#

wondering though can you not use the bow event and use getProjectile to duplicate the arrows?

#


                    double x = arrowLocation.getX();

                    Entity arrow2 = player.getWorld().spawn(player.getEyeLocation().add(arrowDirection).add(x +1,0,0), Arrow.class);
                    Entity arrow3 = player.getWorld().spawn(player.getEyeLocation().add(arrowDirection).add(x -1,0,0), Arrow.class);```

maybe this would do?

#

ill try it ig

leaden parcel Mar 17, 2022, 6:40 PM

#

no

amber jungle Mar 17, 2022, 9:03 PM

Playing with thing, i think you might be looking for:

p.getWorld().spawnArrow(arrowOrigin, (arrowOrigin.subtract(arrowTarget)).toVector(), arrowForce, arrowSpread);

That should allow each arrow to hit the target, or at least close to it
