layer_x

描述

You can use this function to set the x position of the layer within the currently scoped room. You supply the layer ID (which you get when you create the layer using layer_create()) or the layer name (as a string - this will have a performance impact) and the function will move the layer the given number of pixels along the horizontal axis of the room.

语法：

layer_x(layer_id, x)

参数：

参数	描述
layer_id	The unique ID value of the layer to set the x position of
x	The x position in the room to set the layer to

返回：

N/A（无返回值）

例如：

var lay_id = layer_get_id("Sprites");
if layer_get_x(lay_id) != 0 || layer_get_x(lay_id) != 0
    {
    layer_x(lay_id, 0);
    layer_y(lay_id, 0);
    }

The above code checks the given layer position and if it is not set to (0, 0) then it is set to that position.
