はスプライトの動きに固執しました

Question

最近、私は少しプロジェクトを進めてきました。 私は多くの車を産んでいる背景があります。 私は自分が定義した道に沿ってそれらの車を動かすことを望んでいます。私は私の移動方法を呼び出すときに私の車の1つが（0,0）の位置に移動するポイントになった、また、パスに沿って滑らかなアニメーションを持つ方法がわからない、私はしたくない最後のウェイポイントに突然現れる車が即座に定義されます。ここで

は私のコードです：

誰かが私にいくつかのポインタを与えるか、私はそれを本当に感謝し、私はそれを修正するために何ができるかを教えてことができれば！ imageはポジションを維持していないと、それは常に(x,y) == (0,0)

クラスでupdate()を作成し、update()とcar_group.update()内を実行しているため、move_positionで

Answer 1

が

self.rect = self.image.get_rect() 

を使用していないすべてのループでそれを実行します。

私はので、私は誰もがそれを実行することができますので、画像なしで動作し、正しい方向に

radians_angle = math.radians(self.angle) 

self.rect.x -= self.speed * math.cos(radians_angle) 
self.rect.y -= self.speed * math.sin(radians_angle) 

例を移動するために使用することができself.angleでangleを保存します。
