I'm trying to make a block that when the player walks on it they will be randomly teleported, so i figured i could just use the onEntityWalking method then convert the entity to an entityPlayer and then figure out how to make them teleport, but I seem to be unable to cast entity to entityPlayer. does anyone know a way to make entitys teleport or how to cast to entityPlayer

on this is the code with out me trying to teleport the player as i have not figured out how to do that yet.

public void onEntityWalk(World worldIn, BlockPos pos, Entity entityIn)
    {
      if(entityIn instanceof IMob)
      {
    	  return;
    	  
      }
      else if(entityIn instanceof IAnimals)
      {
    	  
    	  return;
      }
      else
      {
    	 EntityPlayer player = (EntityPlayer)entityIn;
    	 //the error here says,"cannot cast from Entity to EntityPlayer"
      }
    }

 

regardless if it is actually player or not it should still let me cast, but your right if i ran the code the way it is now it would probably crash

Have you definitely imported the right

Entity

class?

Writing code that does a cast will always compile.  It's when it tries to cast something and it can't be that it will crash.  There's no syntax error with what you've written, but there is a fundamental problem that will cause runtime exceptions.

Point.

 

However, that's only true when the classes are not related at all.  For cases where you're taking a generic object and downcasting to a more specific one, where it will sometimes be valid, then that won't throw a pre-compile error.

 

eg

 

String s = "hello";
Object o = s;
Integer i = (Integer) o;

Makes sense.
