what do i put in 'getobjectsinrange()'?
The documentation says what parameters you need.
getObjectsInRange
protected java.util.List getObjectsInRange(int radius, java.lang.Class cls)
Return all objects within range 'radius' around this object. An object is within range if the distance between its centre and this object's centre is less than or equal to 'radius'.
Parameters:
radius - Radius of the circle (in cells)
cls - Class of objects to look for (passing 'null' will find all objects).
This is what you would see if you looked up the 'getObjectsInRange' method in the Actor API.
Example:
// etc.
}
if (!getObjectsInRange(5, Worm.class).isEmpty())
{
Worm worm = (Worm)getObjectsInRange(5, Worm.class).get(0);
If you want a list of all objects near to you which are from the type Enemy (or any other class) you do this:
The first part just is the type (java.util.List) and the name of the variable
List<Enemy> enemies = getObjectsInRange(50, Enemy.class);//now 50 is the radius and Enemy.class is the class you are searching for;
If using a statement similar to the code Gevater_Tod4711 supplied, you must add the following at the top of the class:
Also, you need to cast the list as follows:
import java.util.List;
List<Enemy> enemies = (List<Enemy>)getObjectsInRange(50, Enemy.class);
Oh yes I forgot the import.
But do I realy have to cast the list?
I think it should work this way.
@Gevater_Tod4711, it appears you are correct about not having to cast the list; tested and confirmed!
