前言

接上篇文章继续解绍arcade游戏编程的基本知识。游戏的灯光阴影效果

灯光阴影效果 1、灯光效果 1.1 玩家灯光效果

蓝色效果 白色效果

1.2 代码 #创建一个灯光来跟随玩家。稍后，当玩家移动时，我们将对其进行定位。 #我们只会在玩家打开灯光时将其添加到灯光层打开。我们从熄灯开始。 radius = 150 mode = 'soft' color = arcade.csscolor.WHITE self.player_light = Light(0, 0, radius, color, mode) 2、灯光效果 2.1 软效果

2.2码实现 # 白色灯光 x = 100 y = 200 radius = 100 mode = 'soft' color = arcade.csscolor.WHITE light = Light(x, y, radius, color, mode) self.light_layer.add(light) 3、硬效果 3.1 灯光硬效果

3.2代码实现 # 创建三个重叠的RGB灯光，但不会褪色的“硬”灯。 x = 650 y = 150 radius = 100 mode = 'hard' color = arcade.csscolor.RED light = Light(x, y, radius, color, mode) self.light_layer.add(light) 4、灯光开关 4.1 灯光开关

4.2 代码实现 def on_key_press(self, key, _): if key == arcade.key.UP: self.player_sprite.change_y = MOVEMENT_speed elif key == arcade.key.DOWN: self.player_sprite.change_y = -MOVEMENT_speed elif key == arcade.key.LEFT: self.player_sprite.change_x = -MOVEMENT_speed elif key == arcade.key.RIGHT: self.player_sprite.change_x = MOVEMENT_speed elif key == arcade.key.SPACE: #
