Hi,
how can I get a list of object within a range of 40 and save these objects as a variable or something?
And then: how can I remove all these Objects?

Remove object in range
Well, 40 will the the radius of a circle here:
This code must be in a subclass of Actor.
And really, you should read the greenfoot documentation!
1 | getWorld().removeObjects(getObjectsInRange(40)); |
my problem: if i do this i remove all Objects within the range. But I want to remove only the Objects of a specific class
Do this:
1 2 3 4 5 6 7 8 9 | // at the top of the file:import java.util.List;// somewhere:List objects = getObjectsInRange(40);for (Object object : objects) { if (object instanceof ClassNameToRemove) getWorld().removeObject((Actor)object);} |
Doesnt work.
1. thing: I wrote
and i got an error which said: method getObjectsInRange in class greenfoot.Actor cannot be applied to given types; requred: int, java.lang.Class
found: int.
so I wrote then
and the rest of code i copyed.
After that i tried it but the Obect of the given cass does not remove.
Weres my faut?
1 | List objects = getObjectsInRange(40); |
1 | List objects = getObjectsInRange(40, Blocker.class); |
Remove the code and do this:
1 | getWorld().removeObjects(getObjectsInRange(40, Blocker.class)); |
thx
