Anger core

you know the anger core from portal 1 right well this shows you how to recreate it.

making the shell

make a prop_dynamic with the model personality_sphere_skins.mdl and set the default animation to sphere_shiver_all then make another prop_dynamic and set the model to personality_sphere_angry.mdl and make the default animation angry then jam them both together

making it a pickup

create a prop physics that will fit inside the core and a logic auto with outputs so that you can collide with it then make the parent of the prop_dynamics to the prop physics.
