Is it possible to have an entity with more than one action assigned to it.
For example, if I want a plane to move its propeler and at the same time
I wish for it to chase another plan, can I assign more than one action to it?

Thanks!

you might need to have the propeler as a seperate model and the plane as another.
You can use a code to add the propeler to the plane model.

Sure, create your seperate actions as functions then call them when needed in the aeroplane action.
You can have a s many as you want really.

action aeroplane
{
...
while(1)
propeller():
...
}

Thanks so much for the information!
What about if one og my entities has default animation
(Such as a moving propeler), how do I retain this behavior
while adding additional actions to it?

Thanks,

You may do this with one model... just create bones at pivot center of each propeller, attach verticles and use ent_bonerotate function.
Or do it with different models using vec_for_vertex to attach models then change roll or use simple animation.
