gaining access to a public variable
You would need a reference to your Hero object. It is the Hero objects that each hold a 'speed' field which has independent values. The class itself does not have a 'speed' field; it only has a line declaring that each object created from that class will be given a 'speed' field.
If you only have one Hero (which is probably the case), then the following lines will get that reference:
from an actor class (with the actor in the world), use 'getWorld().getObjects(Hero.class)' (getting a reference to the World object to call the World member 'getObjects' on).
// from world class
Hero hero = null; // variable to hold the Hero object (if any)
// can only get first element from list if there is a first element, so
if (!getObjects(Hero.class).isEmpty())
{
hero = (Hero)getObjects(Hero.class).get(0); // setting the variable
}
if (hero != null) // was field set to a Hero object
{
int speedValue = hero.speed; // getting your 'speed' value
// code dealing with speed
}ace. thanks for quick reply danpost :)
