Here you go. I'm using 1st and 3rd person camera. 1st is the main camera but 3rd is used for testing purposes (animation and movement). Just change camera with "t" on keyboard. Double click "w" for sprint. Jump isn't yet implemented.

Code:

#define zoffset skill31
var running;

#define animate skill32
#define animate2 skill33

#define nullframe -2
#define blend -1
#define stand 0
#define run 1
#define walk 2
#define walkSlow 3
#define walkBack 4
#define jump 5
#define fall 6

#define run_animation_speed 7
