Python tupleNormalize示例

示例#1

 def applyGravity(self, ship, deltaTime):
     distance = tupleDistance(ship.getPos(),
                              vec3ToTuple(self.planet.getPos()))
     if distance > Game.GRAVITY_DISTANCE: return
     gravity = Game.GRAVITY / distance
     gravityVector = tupleNormalize(
         tupleSegment(ship.getPos(), vec3ToTuple(self.planet.getPos())))
     gravityVector = scaleTuple(gravityVector, gravity * deltaTime)
     ship.applyForce(gravityVector)

示例#2

def colHandler(ship, contact):
    pos = ship.getPos()

    elasticity = 2.5
    #mass1 = ship.getMass()
    #mass2 = collider.getMass()
    vel1 = ship.getVel()
    normal = tupleNormalize(tupleSegment(pos, contact))
    force = (scaleTuple(normal,
                        -elasticity * (1 / 2.) * dotProduct(vel1, normal)))

    ship.applyForce(force)
    ship.setPos(addTuples(ship.getPos(), scaleTuple(normal, -.1)))
    ship.getCollisions().remove(contact)
