Help needed: removing tiles and objects at certain place

[Dwojityv]

Hello,
I am creating an endless runner game and everything works just fine.
I am moving tiles and objects instead of player (dont ask me why, I just couldnt figure out other way to do It ^^). And thats where I am starting to feel uncomfortable, because I dont remove objects and tiles that leave my roomview.

Okay I know how to remove objects with adding some line of code to the step event what checks if the Object.x < 0 and if It is, remove It. But I would have to manually add this to every object and I believe there must be better way to do It.

About tiles - I have no idea How to remove tiles that are in certain position.

TL;DR:
I need efficient way to destroy all objects and tiles with x position smaller than -150.

Thanks in advance for your replies and sorry for my english, its my third language ^^

Well, what about this ?

// Delete tiles
var _id, _ids = tile_get_ids();
for (var i=0; i<array_length_1d(_ids); i+=1)
{
    _id = _ids[i];
    if (tile_get_x(_id) < -150) tile_delete(_id);
}

// Delete objects
with(all)
{
    if (x < -150) instance_destroy();
}

Just use it in some object that is in the room only once and to make it more efficient you should should put it in alarm.

Wow thats exactly what I needed. I did not know that I can use with(all) and tile_get_ids();

Thank you very much for your quick answer.
