Thank you! and if I want to call a skill of the player ina function what I have to do?
for example:

action player(){my.health=100;}
action npc(){my.health=200;}
function add_health(){
//now to call the health of each one like
player.health+=20;
npc.health+=20;
// but when I use the pointer entities don't work so how to call the skills of each one?
