碰撞检查GMS2

Question

我写了一个碰撞检查代码并运行它，完美地工作，但它只对一个图层工作。 例如，我的代码是获取图层ID并获取该图层中的瓷砖，并给它们一个1和0之间的数字，如果它是1，则有一个碰撞，否则（0）则没有障碍物。我的问题是我有多个图层，比如objects和objects2。但我不能选择 "objects2 "层来获取id。我只能选择 "objects "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;
            }
        }
    }

Answer 1

我在Heartbeast的一个教程中学习了这个方法。

我用一个不可见的对象层来处理对象碰撞 然后用另一个对象层纯粹是为了视觉效果，在碰撞上作画。

我的碰撞对象是透明的方块，这样很容易判断出碰撞的位置。完成碰撞层后，我可以用眼睛符号隐藏它，或者用代码隐藏层。(后面可能会提供例子)

这样一来，碰撞与你使用哪块瓷砖无关，你只需要使用一个图层进行碰撞。
