为什么它会卡在case 5呢？我正在创建我的cutscene，我已经编写了很多函数。但是，我不理解为什么它会卡在case 5。它确实执行了case 5，但是出于某种原因，它认为没有触发cs_step++来移动到下一个cutscene cas

switch(cs_id) {

    case "first_meet":

        switch (cs_step) {

            case 0:

                global.in_cutscene = true;
                camera_set_view_target(view_camera[0], obj_smilie);
                cs_step++;

                break;

            case 1:

                //initialize coords
                move_x = obj_smilie.x;
                move_y = obj_smilie.y;
                cs_step++;

                break;

            case 2:

                //smilie walks a little further than the warp area
                //after moving camera will set noone
                if (scr_obj_move(obj_smilie, move_x, move_y-30, 1, "diag")) {

                    camera_set_view_target(view_camera[0], noone);
                    cs_step++;
