I have an entity that has a main class similar to entity throwable,

I have adjust the eye height that it gets (which I shouldn't have to when not specifying onImpact of PlayerEntity)

+ 0.2000000149011612D instead of - 0.10000000149011612D which entitythrowable has.

 

I have also changed the getGravityVelocity to 0.0

 

Main Class:

previously this worked without having to adjust eye height level. specifying the player such as:

 

{
        if (result.entityHit != null)
        {
            int i = 0;
            if (result.entityHit instanceof EntityLivingBase)
            {
                i = 0;
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.STRENGTH, 200, 1));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.INSTANT_HEALTH, 10, 3));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.REGENERATION, 200, 5));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.JUMP_BOOST, 200, 7));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.SPEED, 200, 2));
                
            }
            
            if (result.entityHit instanceof EntityPlayer)
            {
            	i = 0;
            	((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.STRENGTH, 200, 1));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.INSTANT_HEALTH, 10, 3));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.REGENERATION, 200, 5));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.JUMP_BOOST, 200, 7));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.SPEED, 200, 2));
            }
            result.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), (float)i);
            worldObj.playSound((EntityPlayer)null, posX, posY, posZ, SoundEvents.ENTITY_EXPERIENCE_ORB_PICKUP, SoundCategory.NEUTRAL, 0.7F, 1.3F / (worldObj.rand.nextFloat() * 0.4F + 0.8F));
        }

 

 

 

Not too certain if this is a bug or not, so I figured I'd post it here.

 

When I right click, potion effects are applied to my player even though it is spawned in above his head and onImpact EntityPlayer is not specified.

 

When I hold shift and right click the entity is spawned in and no potion effects are applied. It just sits there in the air then goes to setdead.

 

edit:

....this has got to be either a bug or something being worked on or something....

 

as this does not work:

if (result.entityHit instanceof !EntityPlayer)
            {
                i = 0;
                ((!EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.STRENGTH, 200, 1));

The hell?  What are you trying to do here?

An anti-cast?

 

Also, that's not how you check for "not an instance of."

I don't believe it would work there anyways, haha.  :o:blank:

 

-your link seems to be broken btw.

 

edit:

 

Its so you can heal players and mobs, without applying it to yourself.

To apply it to yourself then you'd shift right click. and that would summon the other entity in, that part I haven't gotten too.

 

that way you can heal everyone, and everything, including yourself in a nice manner while slaying everything undead.

Not sure if this is working or not, will soon find out after making entity2

but by the looks of it this appears to be working:

 

{
        if (result.entityHit != null)
        {
            int i = 0;
            if (result.entityHit instanceof EntityPlayer == false)
            {
                i = 0;
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.STRENGTH, 200, 1));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.INSTANT_HEALTH, 10, 3));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.REGENERATION, 200, 5));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.JUMP_BOOST, 200, 7));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.SPEED, 200, 2));   
            }
            if (result.entityHit instanceof EntityLivingBase == false)
            {
            	i = 0;
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.STRENGTH, 200, 1));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.INSTANT_HEALTH, 10, 3));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.REGENERATION, 200, 5));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.JUMP_BOOST, 200, 7));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.SPEED, 200, 2));
            }
            result.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), (float)i);
            worldObj.playSound((EntityPlayer)null, posX, posY, posZ, SoundEvents.ENTITY_EXPERIENCE_ORB_PICKUP, SoundCategory.NEUTRAL, 0.7F, 1.3F / (worldObj.rand.nextFloat() * 0.4F + 0.8F));

If the entity is not EntityLivingBase, then magically it is an EntityPlayer? That's not type-safe casting.

Not to mention, guess what class EntityPlayer extends... Well look at that, EntityLivingBase, which means Entityplayer IS an instance of EntityLivingBase, because it extends it.

That's why it needs to look similar to this so you can also heal other players, heal entities, and heal yourself when holding shift and right click. Using the above false true etc and matching stuff up back and forth Is not working the same. I can cast it on entities and myself but when going to cast it on other players it won't work.

 

if (result.entityHit != null)
        {
            int i = 0;
            if (result.entityHit instanceof EntityLivingBase)
            {
                i = 0;

I finally fixed it, If it double impacts then it returns a false blank instant health so there is no permanent buff, and I am now able to walk realllly close to mobs and hit them. The false blank can be cleared by just applying the buff again with shift right click. The issue was with the amount of time before the onImpact was recognized. Now it works :)

 

if (ticksExisted >= 2.1001 && result.entityHit instanceof EntityLivingBase)

 

protected void onImpact(RayTraceResult result)
    {
    	if (result.entityHit != null)
        {
            int i = 0;
            if (ticksExisted >= 2.1001 && result.entityHit instanceof EntityLivingBase)
            {
                i = 0;
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.STRENGTH, 197, 1));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.INSTANT_HEALTH, 10, 3));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.REGENERATION, 195, 5));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.JUMP_BOOST, 200, 7));
                ((EntityLivingBase)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.SPEED, 198, 2));   
            }
            if (ticksExisted >= 2.1001 && result.entityHit instanceof EntityPlayer)
            {
            	i = 0;
            	((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.STRENGTH, 197, 1));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.INSTANT_HEALTH, 10, 3));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.REGENERATION, 195, 5));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.JUMP_BOOST, 200, 7));
                ((EntityPlayer)result.entityHit).addPotionEffect(new PotionEffect(MobEffects.SPEED, 198, 2));
            }
            result.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), (float)i);
            worldObj.playSound((EntityPlayer)null, posX, posY, posZ, SoundEvents.ENTITY_EXPERIENCE_ORB_PICKUP, SoundCategory.NEUTRAL, 0.5F, 1.0F / (worldObj.rand.nextFloat() * 0.4F + 0.8F));

EntityLivingBase Is EntityLivingBase and EntityPlayer is EntityPlayer.

 

But the effect will not effect the player when thrown, it will effect entities though.

It will effect other players when thrown.

 

The issue was when you threw it because entityplayer extends entitylivingbase it was applying the effect to the player when this was not what was needed.

this was fixed by adding a timed delay.

instanceof check is if that is the class or if it is an extension of the class ie EntityPlayer is an EntityLivingBase, but EntityLivingBase is not always an EntityPlayer. So by doing a check for EntityLivingBase you are also checking if it is a EntityPlayer. Then you go on to specifically check for EntityPlayer for no reason because it is included in the instanceof EntityLivingBase.

 

Edit: and yes I understand what the original problem was your entity was spawning in the thrower and applying the effects to that player so adding a time delay defiantly worked.

I don't know if its only me, but doing it that way seems to effect the timer and its success to not stick and result in a blank buff icon popping up in the top right of the screen. That's why I do it that way.

That's not quite correct, or at least not clear enough. Since EntityPlayer extends EntityLivingBase, any instance of EntityPlayer is an instance of EntityLivingBase. The reverse is not true, not all instances of EntityLivingBase are an instance of EntityPlayer. This is why you cannot cast an EntityLivingBase to EntityPlayer, unless you first check that the EntityLivingBase is an instance of EntityPlayer.

Yes, my wording on that was not quite right I will amend that right now.

I wouldn't be so harsh as to call it a bug, because on recommended 1.10.2 this worked alright.

The way it looks on my screen having the potion effects like that makes it look like the icons in the top right are spinning around in a circle and flashing.

 

Now that I recall the same happened on unrecommended 1.10.2 where my icon for instant health stuck.

I know that having the internet in the background running or multiple things going at once can cause it to stick too, so its w/e. I aint trippin' bout it.

Just to update this, after cleaning up all my code and making it look spotless the potion effects are applying right and I have no problem at all.

 

instant health doesn't stick.
