[1.8] [Solved] methods #onEntityWalking #onEntityCollideWithBlock

Posted September 21, 20169 yr

Edit: I was registering BlockFluidClassic and not my custom Block class so never called my overrided methods!!!

Having a bit of trouble getting potion effects to work onEntityCollideWithBlock ...I have tried both (World worldIn, BlockPos pos, Entity entityIn) as parameters and (World worldIn, BlockPos pos, IBlockState state, Entity entityIn)

 @Override   
    public void onEntityWalking(World worldIn, BlockPos pos,  Entity entity){

        super.onEntityWalking(worldIn, pos, entity);
        if ((!worldIn.isRemote && entity instanceof EntityPlayer ))
    	((EntityPlayer)entity).attackEntityFrom(DamageSource.wither, 100);
    	
    }  
   //tried using IBlockState needed for 1.8 since there are two possible overloads 

   @Override
public void onEntityCollidedWithBlock(World worldIn, BlockPos pos, Entity entityIn) {

	if (entityIn instanceof EntityLiving ) {

		((EntityLiving)entityIn).addPotionEffect(new PotionEffect(Potion.damageBoost.id, 200, 1, false, true));		//adds potion effect to mobs/ target --strength=damageboost
	}	
		else if (entityIn instanceof EntityPlayer){	

		((EntityPlayer)entityIn).addPotionEffect(new PotionEffect(Potion.confusion.id, 200, 0, false, true));		//adds potion effect to player/target--nausea=confusion
		System.out.print("Called");
		}
		else if ((entityIn instanceof EntityBlackTobo || entityIn instanceof EntityTobieKing || entityIn instanceof EntityTobieQueen)){

			((EntityBlackTobo) entityIn).addPotionEffect(new PotionEffect(Potion.heal.id, 2000, 7, false, true));
			((EntityTobieKing) entityIn).addPotionEffect(new PotionEffect(Potion.heal.id, 2000, 7, false, true));
			((EntityTobieQueen) entityIn).addPotionEffect(new PotionEffect(Potion.heal.id, 2000, 7, false, true));

		}
		  
}

At any rate, not real sure what the four parameters of PotionEffect are, I think it is duration, level ..not sure on the two booleans.

Also @Overriding onEntityWalking is redlined by eclipse . . .it does not seem to work at all in 1.8 ...has that method changed in 1.8 from 1.7.10?

Edit: Looks like #onEntityWalking is now #onEntityCollidedWithBlock with only the three parameters --ie, no IBlockState, and the former #onEntityCollidedWithBlock now has four parameters.

Mine is still not working though. Help appreciated

That means you aren't overriding a method (method signature doesn't match anything). You need to go look at the parent class to determine what the new signature is.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

I don't see that method #onEntityWalking in 1.8

Why is the #onEntityCollidedWithBlock is not working for me in 1.8? in 1.7.10 instead of the BlockPos parameter, it was x, y, z but I did not change anything else? Sry to bother you but I'm sure this is something pitifully simple I'm just f---ing missing it

Block#onEntityWalk(World worldIn, BlockPos pos, Entity entityIn)

and

Block#public void onEntityCollidedWithBlock(World worldIn, BlockPos pos, IBlockState state, Entity entityIn) (Which is only called when the entity is within the collision bounds).

Edited:

#onEntityWalk not coming up for me as a method...perhaps that's a 1.8.9 or later version not 1.8?

The other method Block#public void onEntityCollidedWithBlock(World worldIn, BlockPos pos, IBlockState state, Entity entityIn)is not working for me either maybe something wrong with my coding?

Could you fix your post? I think you typed inside the quote.

Help please ...just a couple more problems to fix with my 1.8 mod update then I can move on to a newer version ..what is wrong with my coding? neither #onEntityCollideWithBlock with IBlockState parameter or without is working

I have no errors in Eclipse, and no crash. The method is simply not being called. My Block class extends BlockFluidClassic.

It may have something to do with canCollideCheck(...)

Not exactly sure how to use that method, I added the following to my RudBlock code and nothing changed.

@Override
public boolean canCollideCheck(IBlockState state, boolean hitIfLiquid){

	//return hitIfLiquid && ((Integer)state.getValue(LEVEL)).intValue() == 1;
//	return false;
	return this.isCollidable();
}

  @Override
  	@SideOnly(Side.CLIENT)
      public boolean isCollidable()
      {
      	return true;
      }

Yes It's also working with minecraft 1.12.2
