Add this line in the while loop of your energy ball:
you = player;
and use the flag IGNORE_YOU for the c_move, that should do it.
If you have trouble with that you might want to check out IGNORE_PUSH and set the push value of the player entity lower than the energy ball push value.

About your function ENDME:
As far as I can tell from the manual, you need a break; at the end of each case branch:
Code:

---

function ENDME()
{
	switch(event_type)
	{
	      case EVENT_ENTITY:	
		my.alpha -= 20 * time;
		effect(explo,50,my.x,normal);
		
		wait (1);
	        effect(explo_smoke,40,my.x,normal);
         	ent_playsound (you, explosion, 300); // sword sound
        	ent_remove (me);
                break;

	      case EVENT_BLOCK:	
		my.alpha -= 20 * time;
		effect(explo,50,my.x,normal);
		
		wait (1);
	
	        effect(explo_smoke,40,my.x,normal);
        	ent_playsound (you, explosion, 300); // sword sound
        	ent_remove (me);
                break;
	}
}

The execution continues until either the closing bracket or a break statement is encountered
