How can I add weapon mecanim to Standard-assets Third Person Controller?

Hi guys,

How can I expand the provided third person controller mecanim from the standard assets with managing rifle combat? I have the animations:

• walking with Rifle,

• running with Rifle

• walking and Aim,

• idleing with Rifle

• standing and aiming

For this mecanim feature I think I need to add this properties:

• WeaponEquipped

• Aiming

When WeaponEquipped should manage the switch between the locomotion blendtree and the RifleLocomotion blendtree.

Should I do a seperate layer? There is no tutorial for starting this with the standard assets TPC out there.

Thanks in advance.
