[HELP] Custom Instance

kuriku · July 4, 2011

I'm making a Custom Instance in Java, and i'm testing different possibilities. But I have a little error when in mi Instance I want to open/close door by java script (when you complete a condition for example).

The Instance runs perfectly. When I kill the two MOBs of the first room, spawns the next condition and spawns three aditional MOBs in the other room. The problem is only with doors.

Here is the full code:

package instances.InstanceTest;

Can someone help me to fix this error?

openDoor() is let null. You must initialize it somehow (surely with door DOOR1).

See how others instances are made on this side (use of openDoor( method).

kuriku · July 4, 2011

All the Instance that I see in L2j have the method openDoor(). For example, in Dark Cloud Mansion or Crystal Caverns. I've just copied the method and I don't know why I have this error if the method identical.
