Hej,

I'm really new to modding and lua, but after I've seen what's possible I thought to try it for myself. So I'm working on a dungeon and use a lot of costum stuff from various users.
I found the NPC Script from Mahric and tried to implement a Skeleton Ghost. I'm really new to lua scripting and tried to copy/paste my way to the goal

.
The skeleton ghost is from Pandafox. It has his own models and textures and so on. How can I add the skeleton ghost into the existing files from Mahric, so that I have this fellow as a NPC?

I tried to copie a definition for a NPC from Mahrics monster.lua and merged the the skeleton_ghost.lua into that. But i get a lot of errors.

The animations refering still to the md_npc_skeleton_warrior animations. Is this a problem? I really don't have a clue. I learned lua via try and error during building my dungeon and that was ok - til now. Now its to complicated.

Can somebody help me?

---- edit:

So I tried it with the normal monsters, to look how it would work, but I get a strange Error:

The editor crashes and creates a error-file. In this version I didn't change anything.

I think what you have is 2 seperate entities using different tricks, or "backdoors" if you will; to simulate things that are not intended to happen. I believe you would need the knowledge to rewrite mahric's pathfinding script to handle how pandafox simulates a "brain". I am not familiar with either work, but generally speaking, 2 peoples projects will not work together in such a way, I'm sorry. On the bright side, you may be able to use blockers and hidden plates to make a rudimentary pathfinding for it, but it is a bit of work to do very much.

Ok thanks, I think thats to high for me.

But isn't it possible to only change the textures of Mahric's skeleton with the textures of the ghost skeleton without to write a new "brain"?

Absolutely possible, but you wont know till you try and break it!
