Make a mob Explode on hit (and have mob live)

[Military Police15]

So I've been trying to make a mob for my mod, and the concept is this: if the mob gets hurt by the player, the mob explodes, but the mob would still live. I've got most of the AI and attributes down, I'm just having trouble finding a way to code it so when the mob is attacked by the player it explodes. Any help would be appreciated, here is what i've got so far

public class Jeff extends EntityMob
{
	
	private int explosionRadius = 3;
	
	protected void initEntityAI()
	{
		this.tasks.addTask(0, new EntityAISwimming(this));
		this.tasks.addTask(1, new EntityAIWatchClosest(this, EntityPlayer.class, 6.0F));
		this.tasks.addTask(2, new EntityAILookIdle(this));
		this.tasks.addTask(3, new EntityAIOpenDoor(this, false));
	}
	
	public float getEyeHeight()
	{
		return 0.5F;
	}

	protected void applyEntityAttributes()
	{
		this.getCreatureAttribute();
		this.getCreatureAttribute();
	}

	protected Jeff(EntityType<?> type, World p_i48553_2_) 
	{
		super(type, p_i48553_2_);
		this.getAttribute(SharedMonsterAttributes.MOVEMENT_SPEED).setBaseValue(0.25D);
	}
	
	
	
}

Override Entity#attackEntityFrom and call World#createExplosion (to create the explosion) if the DamageSource is from a player. Return true in this case as players are able to damage your entity.

If the DamageSource is from an explosion, return false.

I Found some of the code parts you were talking about, and implemented them into my code, but i have a small problem with 'this.damageEntity', which is giving the error 'Entity Living Base is not applicable for the arguments (EntityPlayer, float)

public class Jeff extends EntityMob
{
	private EntityPlayer player;
	private int explosionRadius = 3;
	
	protected void initEntityAI()
	{
		this.tasks.addTask(0, new EntityAISwimming(this));
		this.tasks.addTask(1, new EntityAIWatchClosest(this, EntityPlayer.class, 6.0F));
		this.tasks.addTask(2, new EntityAILookIdle(this));
		this.tasks.addTask(3, new EntityAIOpenDoor(this, false));
	}
	
	public float getEyeHeight()
	{
		return 0.5F;
	}

	protected void applyEntityAttributes()
	{
		this.getCreatureAttribute();
		this.getCreatureAttribute();
	}

	protected Jeff(EntityType<?> type, World p_i48553_2_) 
	{
		super(type, p_i48553_2_);
		this.getAttribute(SharedMonsterAttributes.MOVEMENT_SPEED).setBaseValue(0.25D);
	}
	
	public boolean attackEntityFrom(DamageSource source, float amount)
	{
		if (this.damageEntity(this.player, amount))
		{
			return true;
			World createExplosion;
		}
		else
		{
			return false;
		}
	}
	
	
}

You need to check whether the DamageSource is from a player by checking whether DamageSource#damageType is equal to “player”, not create a new field for player.

 

Do you know Java though? If not, please learn it before making a mod.

I figured I could just learn it as I went along, but i have been having a lot of problems with figuring out what to use where, so I'll try to learn more about it tomorrow
