So I am trying to have an AI-controlled NPC walk around my level. The algorithm that I am using works, except the NPC doesn’t face the right way. I use the same algorithm to have the NPC run at the main character, and he faces the right direction. Yet, when I use it to make the NPC just walk around, whenever he changes direction, he faces a totally random direction instead of facing the direction that he is going. Can someone tell me what is going wrong with my code, or show me a better way to do this.
The code I am using right now is:
if ((self.counter%175) == 0): self.theta1 = (random.random()*359) self.dX1 = (math.cos(self.theta1)*.17) # this is how far the NPC moves on the X-axis self.dY1 = (math.sin(self.theta1)*.17) # this is how far the NPC moves on the Y-axis if (abs(self.deltaX) >= 80 or abs(self.deltaY) >= 80): self.badGuy.setH(self.theta1) self.badGuy.setPos(self.badGuy.getX()+self.dX1, self.badGuy.getY()+self.dY1, 0)
