我已经编写了一个碰撞检查代码并运行它，运行良好，但它只适用于一层。例如，我的代码正在获取图层 id 并获取该图层中的图块并给它们一个介于 1 和 0 之间的数字。如果为 1，则表示碰撞，否则 (0) 则没有障碍物。我的问题是我有不止一层，比如对象和对象2。但是我不能选择“objects2”层来获取id。我可以选择“对象”层。这是我的代码：

"CREATE" EVENT IN COLLISION OBJECT "obj_collision"

var lay_id = layer_get_id("Objeler");
var lay_id2 = layer_get_id("Objeler2");
var map_id = layer_tilemap_get_id(lay_id);
var map_id2 = layer_tilemap_get_id(lay_id2);

hcells = room_width / 16;
vcells = room_height / 16;

for (var yy = 0; yy < vcells; yy ++){
    for (var xx = 0; xx < hcells; xx ++){
            //Bu kod tile'ın integer değerini veriyor.
            tile = tilemap_get(map_id, xx, yy);         

            if (tile <= 6){
                //Hareket edebilir.
                a_grid[xx,yy] = 0;
            }else{
                //Hareket edemez.
                a_grid[xx,yy] = 1;
            }
        }
    }

    for (var yy = 0; yy < vcells; yy ++){
    for (var xx = 0; xx < hcells; xx ++){
            //Bu kod tile'ın integer değerini veriyor.
            tile2 = tilemap_get(map_id2, xx, yy);           

            if (tile2 <= 6){
                //Hareket edebilir.
                a_grid2[xx,yy] = 0;
            }else{
                //Hareket edemez.
                a_grid2[xx,yy] = 1;
            }
        }
    }

我在 Heartbeast 教程之一中学习了这种方法：

我使用一个不可见的对象层进行对象碰撞，并使用另一个对象层纯粹用于视觉效果，以绘制碰撞。

我的碰撞对象是透明的正方形，这样很容易分辨出碰撞的位置。一旦我完成了碰撞层，我可以用眼睛符号隐藏它，或者在代码中隐藏这些层。（稍后可能会提供示例）

这样，碰撞与您使用的瓷砖无关，您只需使用一层进行碰撞。
