如何将图像(玩家)旋转到鼠标方向?
创建 2D 射击游戏时,让玩家能够瞄准鼠标光标的方向。然而,找到解决方案可能具有挑战性。
问题描述
玩家图像(Player_1)需要根据鼠标位置动态旋转以增强瞄准能力
解决方案
为了实现这一点,我们需要计算玩家位置和鼠标光标位置之间的角度。这是通过以下方式实现的:
<code class="python">import pygame, sys, os import math # ... (rest of the code remains the same) def game_loop(): while True: events() mx, my = pygame.mouse.get_pos() # Get the mouse position player_rect = Player_1.get_rect(topleft=(P_X,P_Y)) # Get the player's rectangle dx, dy = mx - player_rect.centerx, player_rect.centery - my # Calculate the vector from the player to the mouse angle = math.degrees(math.atan2(-dy, dx)) - correction_angle # Compute the angle of the vector rot_image = pygame.transform.rotate(Player_1, angle) # Rotate the player image by the calculated angle rot_image_rect = rot_image.get_rect(center=player_rect.center) # Get the rotated image's rectangle DS.fill(White) DS.blit(rot_image, rot_image_rect) # Blit the rotated player image pygame.display.flip()</code>
Correction_angle 是一个常量,取决于玩家精灵的初始方向。常见值为:
该方法允许玩家图像旋转并准确瞄准鼠标光标位置,增强游戏体验。
