Question

最近我开始研究第三人称3D mmorpg幻想游戏，但我似乎无法根据时间量计算出玩家的旋转和移动。那么我需要在代码中进行哪些更改才能使角色旋转，然后能够在该方向上同时行走或同时行走。

我的目标是https://www.youtube.com/watch?v=PoxDDZmctnU和https://www.youtube.com/watch?v=d-kuzyCkjoQ这样的事情我尝试将代码翻译成python但是它不起作用，我的播放器遍布整个地方。请帮帮我。

这是我的代码：

玩家类

class Player:
    def __init__(self, model, engine):
        self.model = model
        self.engine = engine

        self.RUN_SPEED = 0.1
        self.TURN_SPEED = 0.6
        self.GRAVITY = -0.01
        self.JUMP_POWER = 2

        self.TERRAIN_HEIGHT = 0

        self.currentSpeed = 0
        self.currentTurnSpeed = 0
        self.upwardsSpeed = 0

        self.isInAir = False

        self.position = [0,0,0]
        self.rotation = [0,0,0]

    def move(self):
        Yrot               = 1.0 * (self.currentTurnSpeed * self.engine.getFrameTimeSeconds())       
        distance           = 1.0 * (self.currentSpeed * self.engine.getFrameTimeSeconds())
        self.upwardsSpeed += 1.0 * (self.GRAVITY * self.engine.getFrameTimeSeconds())
        dx = 1.0 * (distance * sin(Yrot+self.rotation[1]))
        dz = 1.0 * (distance * cos(Yrot+self.rotation[1]))

        self.increaseRotation(0,Yrot,0)
        self.increasePosition(dx, 0, dz)

        dy = 1.0 * (self.upwardsSpeed * self.engine.getFrameTimeSeconds())
        self.increasePosition(0, dy, 0)
        if self.position[1] < self.TERRAIN_HEIGHT:
            self.upwardsSpeed = 0
            self.position[1] = 0
            self.isInAir = False

    def jump(self):
        if not self.isInAir:
            self.upwardsSpeed = self.JUMP_POWER
            self.isInAir = True

    def render(self):
        self.model.draw(pos=self.position, rotations=self.rotation)

    def handleEvents(self, event):
        if event.type == KEYDOWN:
            if event.key == K_w:
                self.currentSpeed = self.RUN_SPEED
            elif event.key == K_s:
                self.currentSpeed = -self.RUN_SPEED

            if event.key == K_a:
                self.currentTurnSpeed = self.TURN_SPEED
            elif event.key == K_d:
                self.currentTurnSpeed = -self.TURN_SPEED

            if event.key == K_SPACE:
                self.jump()

        else:
            self.currentSpeed = 0
            self.currentTurnSpeed = 0
    def increaseRotation(self,dx,dy,dz):
        self.rotation = [self.rotation[0]+dx,
                         self.rotation[1]+dy,
                         self.rotation[2]+dz]

    def increasePosition(self,dx,dy,dz):
        self.position = [self.position[0]+dx,
                         self.position[1]+dy,
                         self.position[2]+dz]

main.py，可能没有必要，但只是有人需要它来帮助理解我的代码才能帮助我;）比抱歉更安全

我修复了它，我忘了将self.rotation [1]转换为radians

dx = 1.0 * (distance * sin(radians(Yrot+self.rotation[1])))
dz = 1.0 * (distance * cos(radians(Yrot+self.rotation[1])))

修复：如何在pygame，python和opengl中制作移动角色第3人？
