我打算用draw的方法绘制武器精灵，代码是这样的:
draw_self();
if state == "atk1" {
if (image_index == 0) draw_sprite_ext(wp_1,0,x-2,y-16,1,1,35,image_blend,image_alpha)
if (image_index == 1) draw_sprite_ext(wp_1,1,x+5,y+6,1,1,-90,image_blend,image_alpha)
if (image_index == 2) draw_sprite_ext(wp_1,2,x+2,y+9,1,1,-175,image_blend,image_alpha)
}
wp_1是武器精灵，坐标和武器位置我都测过了，没问题
但是实际运行时，武器精灵一闪一闪的，貌似是中间有几帧没有绘制，如何解决呢？
感谢

应为image_index是很多时候不是整数，它可能是0，0.2，1.5之类的。
所以你要加上floor()
if state == "atk1" {
if (floor(image_index) == 0) draw_sprite_ext(wp_1,0,x-2,y-16,1,1,35,image_blend,image_alpha)
if (floor(image_index) == 1) draw_sprite_ext(wp_1,1,x+5,y+6,1,1,-90,image_blend,image_alpha)
if (floor(image_index) == 2) draw_sprite_ext(wp_1,2,x+2,y+9,1,1,-175,image_blend,image_alpha)
}
