NMS Entity collision help

So with the update to 1.8 the Height float from the entity class was removed and with that being said I have no idea what to use in place of it. I'm trying to make it so when someone shoots an arrow it will pass through the other player

Code:

Class c = Class.forName(currentVersion + ".Entity");
Field field = c.getDeclaredField("width");
Field field2 = c.getDeclaredField("length");
field.setFloat(handle.invoke(p), (float) width);
field2.setFloat(handle.invoke(p), (float) length);

 

What's your overall goal? Like what plugin are you coding this for?

 

I'm trying to make it so when someone shoots an arrow it will pass through the other player.

 

Isn't that the default behavior of an arrow?

 

Oops lol. Wrong wording, I want arrows TO pass through players. I'm not sure what to use from the entity class, but there's definitely a method/float lying around in there.

 

When the player shoots the arrow, remove it and replace it with a custom arrow and then set the custom arrow's velocity to the original arrow's velocity.

For the custom arrow, override it's collide(Entity entity) method and cancel the collision by returning the method after damaging the entity given in the parameter.

 

I could do that, but it wouldn't work well with other methods. I have custom abilities in this plugin. I need a working float/method from the entity class (or any class) so I can update the previous method of cancelling arrows when players are invisible. Before the height float was removed, The plugin was able to set height,length and width to 0 resulting in the arrow to passthrough them. I'm using libshungergames btw, so I'm trying to fix spectators in 1.8 from being hit with arrows. I've updated the plugins reflectionmanager entirely, but can't find a solution to this one issue.

 

Maybe you can add a custom event that fires when an arrow hits an entity. It'll make the coding a bit easier and cleaner.

 

I wish height float wasn't removed , Oddly enough, setting length and width to 0 does basically nothing

 

Maybe you can shrink the bounding box? I don't know, I've never messed around with bounding boxes.

 

@CullanP Could override the default behavior for Projectile collision so that when the Entity it collides w/ is an EntityPlayer who is in the Spectator gamemode isn't considered as a collision (which, while it isn't the most easiest thing, its definitely possible).

Edit: 1.7 point of handling would be something round https://github.com/Bukkit/mc-dev/blob/master/net/minecraft/server/EntityProjectile.java#L129
Not sure if 1.8 logic for projectiles were changed, though its possible.

 

I'm going to try editing the bounding box and see where that gets me, I'll update this thread after trying
