[1.7.2]Custom Arrow

Jetfan16ladd · December 5, 2014

I want to create a custom arrow for my mod and I have a few questions.

M first question is: Is there anyway to make a arrow that explodes 3 seconds after hits something?

Also is there a way to make it so that on contact with a entity it gives a potion effect to the entity.

I have not found any tutorials on how to render the arrow( When I shoot the bow I want to actually see the arrow).

If u know of a tutorial or a way to do any of these things please post here.

If you take a look at both the EntityArrow.class and EntityThrowable.class, they should get you started. They both implement IProjectile, so you could mesh them together to create what you want.

In EntityThrowable - there is an onImpact method. You can override this to wait the 3 seconds, create and explosion, then set the arrow to die.

@Override
protected void onImpact(MovingObjectPosition position) {
  if (!this.worldObj.isRemote) {

    // call the sleep command to wait 3 seconds - not sure what it is in JAVA

    worldObj.newExplosion(this, position.blockX, position.blockY, position.blockZ, 5 + rand.nextInt(3), true, true);
    this.setDead();
  }
}

Also might want to take a look at this:

https://github.com/Draco18s/Artifacts/blob/master/main/java/com/draco18s/artifacts/entity/EntitySpecialArrow.java

The class is coded to accept all kinds of special effects, though I only needed two: knockback and explosions. Look at

hitEffect(Entity entityHit)

Also, I think its set up to "always inflict damage" (ignores

hurtResistanceTime

) which was based off of having a "shotgun" effect working properly.

Because it extends EntityArrow, I never set up a special renderer.

Hi

You may need to derive your arrow from EntityArrow; if you don't you might get a weird symptom where the arrow sticks in the wrong place and then suddenly jumps to a new position.

The only problem I have is that when I extend entityarrow it doesn't let me use @override before onimpact. Also I am not sure what constructors to use.

The error that I keep on getting in the console is AL lib: (EE) alc_cleanup: 1 device not closed

Draco18s · December 6, 2014

Well. Thread.sleep is not going to make the arrow "wait a second" before exploding. It will cause the game to "freeze entirely for a second" then explode.

Jetfan16ladd · December 6, 2014

How do I make just the arrows explosion have a delay?

TheGreyGhost · December 6, 2014

Hi

Post your entire crashlog in pastebin? The line you quoted as the error isn't the actual cause of the crash.

You make a delay by counting ticks in onUpdate or similar.

Eg for 3 seconds, that is 3 seconds * 20 ticks / second = 60 ticks

Every time onUpdate is called, count up by one. When you get to 60, explode.

The error you get when using @Override before onImpact is a warning that you have a spelling mistake or incorrect parameters in your onImpact method

eg onimpact(..) instead of onImpact(...)

brandon3055 · December 6, 2014

Get the arrows age when it first hits the object then when the arrows age is x number of ticks greater the when it hit the block make it explode.

coolAlias · December 7, 2014

EntityArrow does not have an onImpact(MovingObjectPosition) method at all - that's why you get an error 'overriding' it. It can be quite tricky to extend EntityArrow and get any real functionality out of it, but it is possible.

My solution was to take advantage of the fact that 'onEntityUpdate()' does not do anything in EntityArrow, thus allowing me to override onUpdate() with my own code and still get the standard Entity class update functionality, and then rewrite the entire class around that so that I could manipulate any part of it that I wanted.

Battlegear2's solution is much simpler, but not quite as flexible: use Forge events to trigger methods within your arrow class.

Both approaches have advantages and disadvantages; it all depends on what you need to accomplish. For yours, BG2's approach is probably easiest - check when an entity is hit with your arrow, then spawn an exploding entity at that position with a timer of 3 ticks (or however many you need). Reason for the extra entity is EntityArrow is set to dead when it strikes an entity, so you will no longer have the benefit of its update tick (in this particular solution), unless you only want it to explode when hitting the ground.

coolAlias · December 7, 2014

First, please don't P.M. me about problems - the forums exist for everyone to learn.

Second, learn Java - you would know what to do with most of the errors you mentioned if you just took some time to study. I mean come on, you copied the Battelgear2 code exactly into your project and it's complaining because it can't find other class and object references - what did you expect to happen?

Third, my apologies - I forgot to mention that Battlegear2 uses byte-code manipulation to make certain fields in EntityArrow public, but even this would not be a problem for you if you understood Java better.

I know this may sound harsh to you, but it really does boil down to the very simple fact that you aren't going to get very far until you become comfortable with Java.

Draco18s · December 7, 2014

Or you could use my custom arrow:

https://github.com/Draco18s/Artifacts/blob/master/main/java/com/draco18s/artifacts/entity/EntitySpecialArrow.java

Which doesn't have any non-Minecraft imports, already deals with the onImpact problem, and is easily modifiable to add potion effects. See line 321.

Jetfan16ladd · December 8, 2014

I tried the code but I am getting errors on ArrowEffect. Do I have to create a class or something?

Jetfan16ladd · December 8, 2014

Nvm I fixed it.

Jetfan16ladd · January 18, 2015

Now when ever I shot the explosive bow it crashes.

Null pointer errors are easy to fix.

go to the line it indicates, look at it, figure out what objects could possibly be null, backtrace to figure out why.

Jetfan16ladd · January 18, 2015

I am at the line but I cannot figure out what is incorrect or how to fix it. The line is called setStatsByEffect.

Jetfan16ladd · January 18, 2015

Btw Draco wrote this code so idk what much of it means or how it works.

Draco18s · January 18, 2015

Well the thing that looks null is an object of type ArrowEffect.

Figure out why it is null. Which constructor are you calling, what's the default value, etc.

Jetfan16ladd · January 18, 2015

I cannot figure out why it is null. Also was I supposed to make a arrow effect class? Is the error in that class or in the entity explosive arrow class?

Jetfan16ladd · January 18, 2015

I fixed it. It was a error with the greenbow2 class.

Draco18s · January 18, 2015

I fixed it. It was a error with the greenbow2 class.

Tada. There was no way we could have figured that out from the code you posted.

And now you know how to debug.
