help out with this script please

[leaf me alone]

temp.a = this.x
temp.b = this.y
Incrementing this.x makes it go horizontally sideways
Incrementing this.y makes it go vertically upwards / downwards
Put it in a loop that increments the x / y value.
Don't forget to put the gani in the loop as well.
For style points,make sure the npc is facing the right direction.
