I know this might sound strange but is it possible to redefine an entity's function or action at runtime?

I currently have a basic workaround that creates a new entity using ent_create, with the new function name, and then i get the properties of the existing entity (x,y,z,pan,roll etc), and set them to the new entity.

This sort of works, but it takes time and i don't know if i can set all properties, like flags etc.

Couldn't you just end the currently assigned action and start the new function and set its my-pointer to the entity's pointer?

Yes, just call the new action from the entity's old action, and then terminate the old action.

hmm i know how to do that, i should of said i'm looking for something that can do it outside of the entity's action.

like ent_set_function(entity,function).

You could do it outside the entity's action.

Call a new function and inside this function set the my-pointer to the entity's pointer.

If you call the new function from inside the old action the my-pointer is set per default to the entity's pointer.

What i'm doing is creating a small utility that generates actions. Entities are placed in WED and by default have no action applied to them. I'm trying to link the action i create using my utility, to the entity in WED.

I'm trying to do it programatically at the start of my script. I know the name of the action i generated, and which entity it must be linked to.

If there was a way to modify the .wmb file, and change the name of the action then it would be ok, but there isn't.

Why should you write it into the .wmb file???

Why don't you set the my-pointer in your function if you know the name and the entity?

you don't have to do it inside.
you can do it from outside like that:

my = entity;
new_function();

my simply is a global variable that always gets stored/restored by wait().

i do something very similar in my python wrapper. only with lite-c the WED actions get started automatically. in my python wrapper i have to do it manually. so i have my own level_load() function which reads the action names from the wmb file and then simply sets the my pointer before calling the right function. it works exactly like in lite-c.

and you could modify a wmb file of course. the file format specifications are in the manual. you could look into my a7_scheduler.py and the function get_actions() to see how i read the actions. writing the actions would only require some small changes.

yes, that's another way to set the my-pointer.

Oh, would you mind telling me how you can read the action names?


I can actually edit the .wmb files, and update the names of the actions inside? I thought this couldn't be done. If so could you explain how i can do this? Thanks.
