The characters which are in the classics/characters are not working right.Zombies are not attacking player.I tried to change their main like ai_fastzombie.lua they started to attack but their animations went crazy.What's the problem pls help.

Looks like the script you changed to uses the wrong animation frames. not used the old models in ages and I am guessing they are broken at the moment.

U need the ai_zombiewalk3.lua script 4 that model

You can not randomly swap scripts from model to model as they tend to reference different animations

The annoying thing is, there is a system in place so we can do exactly that, but a lot of the older characters aren't set up for it.

All the zombies can work with all the AI scripts, if the anim references were set up properly in the fpe, as simple as that, and all the zombie scripts would work with any character if whoever had written them had designed them to read the anim references in the fpe instead of choosing the quick and easy method of hard coding the animation frames in the script.

All of the characters we have in gameguru are perfectly capable of working with all AI scripts, if the FPE's are set right and the scripts use the fpe anim reference method. If i knew how to script AI i would go through all the characters and fix their fpe's and write new zombie and melee script, i know it can be done, but i just don't know how

Taking into account than there is just 1 soldier model base, and the others just are like instances of him, with the same behaviour,just change the uniform, driving by the same scripts; we can't wait them behaves different ways.

GG seems to have taken the uber soldier as a base model, and uses it even in the characters created by CC, as clones of the uber soldier.
Variation is what is needed, characters that behave differently, with different virtues and defects, obviously guided by different and personalized scripts.
As Belidos points out, the animations can be read from the fpe file by the script, and reproduced accordingly. Anything can be read from almost any GG file, and used in the script. You have a sample in the script forum.
I think I've almost never used Classic characters, but I don't know to what extent they work in GG.

but ai_zombiewalk3.lua actually works 4 that zombie nurse

Not for me its not ?

Do u working on a game project?

Just an FYI its always better to upload videos on Youtube and share the link here. Better for mobile as well as not everyone is prepared to download videos.

You can make the Youtube videos "Unlisted" and still share the links here. That way only we can see it.

EDIT: Just did a test with the old zombie characters (these are extremely old) and they do not appear to be responding. So the classics script may need to be rewritten.
