我是 GML 新手，昨天才开始。我不知道为什么“spawn_off_camera”中的“repeat(num1)”根本不起作用，我重新检查了很多次，但似乎没有任何问题。你能帮我修一下吗？

我的错误：

############################################################################################
ERROR in
action number 1
of Create Event
for object <undefined>:

DoConv :1: illegal undefined/null use
 at gml_GlobalScript_spawn_off_camera (line 9) - repeat(num1){
############################################################################################
gml_GlobalScript_spawn_off_camera (line 9)

生成关闭相机：

var obj = argument0;
var num1 = argument1;
var xx,yy;


var paddding = 64;

repeat(num1){
    xx = random_range(0,room_width);
    yy = random_range(0,room_height);

    while(point_in_rectangle(xx,yy,global.cameraX- paddding,global.cameraY- paddding, global.cameraX+global.cameraWidth-paddding, global.cameraY+global.camHeight- paddding)){
        xx = random_range(0,room_width);
        yy = random_range(0,room_height);

    }
    instance_create_layer(xx,yy,"Instances",obj);
}

obj_game 房间开始：

if(room == rm_game){
    spawn_off_camera(obj_asteroid,40);
    
    if(audio_is_playing(msc_song)){
        audio_stop_sound(msc_song);
    }
    audio_play_sound(msc_song, 2, true);
    
    alarm[0] = 60;
}

obj_game 警报 0：

if(room != rm_game){
    exit;
}
spawn_off_camera(obj_asteroid,1);

alarm[0] = 1*room_speed;

如果您使用的是 GameMaker Studio 2.3 或更新版本，要使用较旧的脚本/教程，您需要将脚本内容包装在function <name>() {<code>}.

所以spawn_off_camera可能是

function spawn_off_camera() {
var obj = argument0;
var num1 = argument1;
var xx,yy;


var paddding = 64;

repeat(num1){
    xx = random_range(0,room_width);
    yy = random_range(0,room_height);

    while(point_in_rectangle(xx,yy,global.cameraX- paddding,global.cameraY- paddding, global.cameraX+global.cameraWidth-paddding, global.cameraY+global.camHeight- paddding)){
        xx = random_range(0,room_width);
        yy = random_range(0,room_height);

    }
    instance_create_layer(xx,yy,"Instances",obj);
}
}
