[SOLVED]Checking to see what entity is being hit by sunlight.

[Mopop]

I want creepers and other monsters that don't normally burn at daylight to burn. I see the code in the EntityZombie and figured I could use this and rewrite it or to possible just add it into the existing creature code? Or would I better off just making a "custom" mob?

 

 

 

public void onLivingUpdate()

    {

        if (this.worldObj.isDaytime() && !this.worldObj.isRemote && !this.isChild() && this.func_190730_o())

        {

            float f = this.getBrightness(1.0F);

 

            if (f > 0.5F && this.rand.nextFloat() * 30.0F < (f - 0.4F) * 2.0F && this.worldObj.canSeeSky(new BlockPos(this.posX, this.posY + (double)this.getEyeHeight(), this.posZ)))

            {

                boolean flag = true;

                ItemStack itemstack = this.getItemStackFromSlot(EntityEquipmentSlot.HEAD);

 

                if (!itemstack.func_190926_b())

                {

                    if (itemstack.isItemStackDamageable())

                    {

                        itemstack.setItemDamage(itemstack.getItemDamage() + this.rand.nextInt(2));

 

                        if (itemstack.getItemDamage() >= itemstack.getMaxDamage())

                        {

                            this.renderBrokenItemStack(itemstack);

                            this.setItemStackToSlot(EntityEquipmentSlot.HEAD, ItemStack.field_190927_a);

                        }

                    }

 

                    flag = false;

                }

 

                if (flag)

                {

                    this.setFire(;

                }

            }

        }

 

        super.onLivingUpdate();

    }

You can't just rewrite existing methods or add methods to existing classes.  And creating a custom mob won't really solve your problem either.

 

What you should do is subscribe to the LivingUpdateEvent and use the zombie code to set other mobs on fire.

[Mopop]

Okay cool I almost have it all re-written and ready to go but I'm not sure what this line means? And what it wants.

 

super.onLivingUpdate();

 

Once I have that figured out I can test it out.

[Mopop]

Well I'm going to head to bed. I have it working, but it keeps burning NPCs and Players. Is there a simple way of just checking what entity is what?

[Lambda]

instanceof

might work.

Ignore it. You aren't writing a method override in a subclass, so you don't need it.

[Mopop]

Cool, it all seems to work when I run it in debug mode. As soon as I jar it and put it into a live game it crashes when the world loads.

This is line 39 (Along with the old call I had in there, that gave me the same error)

 

World world = Minecraft.getMinecraft().theWorld; //entity.getEntityWorld();

 

Why would it say the method doesn't exist? I'm sure it's probably some little nuance I'm doing wrong, but why would it work on the debug server too? I've removed all other mods too and it still crashes.

 

-Thank you so much for all of your help so far.

Why are you using Minecraft.getMinecraft()? Where are you using it?

[Mopop]

I was just poking around and trying different things. I originally used

entity.getEntityWorld

 

Here is the full method.

 

 

       public void BurnMobs(LivingEvent.LivingUpdateEvent e) {
            Entity entity = e.getEntity();
            World world = Minecraft.getMinecraft().theWorld; //entity.getEntityWorld();
            Random rand = new Random();

            if (world.isDaytime() && !world.isRemote && !(entity instanceof EntityPlayer) && !(entity instanceof EntityAnimal)
                    && !(entity instanceof EntityVillager) ) {
                float f = getBrightness(1.0F, world, entity);

                if (f > 0.5F && rand.nextFloat() * 30.0F < (f - 0.4F) * 2.0F && world.canSeeSky(new BlockPos(entity.posX, entity.posY + (double) entity.getEyeHeight(), entity.posZ))) {
                    boolean flag = true;


                    if (flag) {
                        entity.setFire(;
                    }
                }
            }
        }

 

[Animefan8888]

Couple critiques

• Instead of event.getEntity() use event.getEntityLiving() and use an EntityLivingBase field.
  
• Go back to using entity.getEntityWorld()
  

[Mopop]

Ok I changed the code as recommended. I'm still getting the error when it's live, but it still works in debug mode on the IDE. I put a breakpoint on the line it's complaining about and it seems to run the

entity.getEntityWorld()

fine.

 

However I did notice this when I looked at the crash report

Is the null EntityType causing this? What is different about the game when running it through the IDE?

[Animefan8888]

How are you compiling your mod?

[Mopop]

In intelliJ using the Gradle sidebar. build->clean->jar

In intelliJ using the Gradle sidebar. build->clean->jar

You need to use the forge gradle building I believe. Never used intelliJ, but this should help.

That did it! Thanks so much.
