yes

@ Dico: I just sent you a PM.

Well let Dico take over.

Notes - All ent_bone function pass(return non-zero), which means the bone, by name was found.
Ent_bonerotate (..constant*time_step) shows no visible results, which means the mouse input not the problem. last vertex move in med so have some attachment.

Mal out, peace

So, it turns out that I needed to place my ent_rotatebone() function after all the ent_animate() functions in my player_code() function. The ent_animate() functions were resetting the ent_rotatebone().

Big thank you to Dico who helped me figure this out. :-)

put some cheese on the bone or get a dog

Right now, my code looks like this:



I hate to ask this, but is there a way to limit how far the player model using the ent_bonerotate() function will bend forward and backward at the waist (limit how much the waist bone will rotate?), independent of how far the camera will tilt and rotate behind the player? That way, if I look straight up, the player's head and shoulders will not block the camera's view looking straight up?

Thank you Malice. It worked.

Welcome Ruben ..
Add Clamp() to your memory, you'll find many times you'll need it.
floor() and cycle() and abs() and sign() and of course random/random_seed(). All found in that same var arithmetics section of the manual, all very useful.
