How can I detect if a mob is spawned?

[wara286]

I´ve got a question: How can I detect wether a mob is spawned?

I´m going to code a mod that kills bat´s if they spawn,  but how can i detect if they spawn and how can i get the entity to kill it?

Forge events.  There's one, I believe, for entity spawns, but you could also use EntityLivingEvent which occurs every tick.  Just test to see if the entity passed is an instance of EntityBat, and if it is, kill the entity (setDead() will just remove it from the world without triggering death sounds, etc. unlike kill())

EntityJoinWorldEvent.

Not sure what kind of mob would actually stop bat from spawning instead of killing it afterwards, but, who knows ?

Hi

 

It kind of depends on what you want to do.

 

Is your entity like a sentinel or something, that sits and waits until a bat comes into range then hunts it down?

Or do you want bats to never spawn at all if there is at least one of your entity in the world?

Or do you want the entity to instantly know if a bat is spawned, then move to it and kill it?

 

Different answers in each case...
