[1.7.2] Custom Arrow problems


brandon3055

Recommended Posts

I am trying to create a custom arrow for my custom bow but i have run into some problems.

At first the arrow was hitting the player when it was was fired. I was able to partially fix this problem buy removing super.onUpdate() from onUpdate() however the arrow still "visually" hits the player which looks terrible. I tried this fix  http://www.minecraftforge.net/forum/index.php/topic,16368.msg94429.html#msg94429

but was unsuccessful.

This is my custom arrow code as it is now.

If anyone can help me fix this problem it would be much appreciated

My custom bow is almost the same as the vanilla bow and works fine with the vanilla arrow entity but if you would like to see that code to i would be happy to post it.

If you remove "super.onUpdate()", you must replace it with "super.onEntityUpdate()" so you still get the benefit of the Entity#onEntityUpdate() code; luckily, this is possible because Entity#onUpdate() just calls #onEntityUpdate(), meaning you can bypass EntityArrow's onUpdate() method in this way while still calling a super method.

 

"shootingEntity", "canBePickedUp", and "arrowShake" are all public fields of EntityArrow - you do not need to add them again to your class, and doing so actually deprives you of the benefits of inheritance, since you now have to do all the work on those three fields yourself, rather than letting EntityArrow do it for you, not to mention giving them the exact same name is a potential cause of confusion (e.g. this.shootingEntity and super.shootingEntity are NOT the same!).

Thanks I lost count of how many times I went over that code but somehow I missed those every time. And thanks for the super.onEntityUpdate() fix it also seems that the custom datawatcher is not needed.

 

I just have one more annoying problem I need to figure out. I have modified the damage code to prevent enderman from teleporting away from the arrow.

DamageSource damagesource = null;

if (this.shootingEntity == null) {
    damagesource = DamageSource.causeArrowDamage(this, this);
} else {
    damagesource = DamageSource.causeArrowDamage(this, this.shootingEntity);
}
if (movingobjectposition.entityHit instanceof EntityEnderman)
    damagesource = DamageSource.magic;

And this works the arrow damages enderman end the enderman doesn't teleporting away but it dose "visually" teleporting for a second then snap back to its original position. I suspect for some reason the endermen is still teleporting client side then the client re syncs with the server. Any idea why this is happening?
