game-maker - Gamemaker Studio 2 中的弹丸不动

Question

我的枪的开始步骤代码：

if (global.night == true) {

    image_angle = point_direction(x, y, mouse_x, mouse_y);
    image_index = 1;
    alarm[0] = 0.5 * room_speed;
    firingdelay -= 1;

    if (mouse_check_button_pressed(mb_left)) && (firingdelay < 0) {

        firingdelay = 10;
        with (instance_create_layer(Revolver.x+12, Revolver.y, "Bullets", Bullet)) {
            direction = Revolver.image_angle;
            speed = 25;
            image_angle = direction;
        } 
    }
}

它会产生子弹，但它们不会移动。任何人都可以帮忙吗？

如果您在房间中启用了物理，则常规的速度和方向变量将不起作用。你启用物理了吗？代码看起来不错。
