That @override macro tells java that the object you're in is taking over a method in the object you extended. It'll stop the compiler if it can't find the method it's overriding. Maybe just remove @override? Or should it be overriding something? In which case you've implemented it incorrectly or it's just a mistake.

I was just going to recommend that you go look at the interface function and make sure you check if the arguments match, but the post earlier:

 

remove "String target" argument

 

Read your post a bit better than me.

 

In the function

public boolean useVoicedCommand(String command, L2PcInstance activeChar, String target)

 

You added the String target argument. Because this doesn't match the interface definition you've actually made a completely different function. The @override macro is reporting an error because that definition doesn't exist in the interface.

By the time you use one of my shares you can also PM me.

 

In case this is still unsolved, the error occurs because the pack you use doesn't contain one of the overriden methods I used.

 

You are propably missing the whole voiced command feature.

    • This update resaves 25_25 from the original (with sounds) (without the cave below) Some emitter fixes (removed waterfalls with high-poly meshes) The geodata is old, but it works Everything else is unchanged Download P.S. The effect files are taken from the high client for Interlude, so if you're experiencing critical skills, use the default ones for your Version.
