This function can be used to get the current speed multiplier value of the background element. You give the background element ID (which you get when you create a background element using layer_background_create() or when you use the function layer_background_get_id()), and the function will return real value that represents the speed multiplier being used to animate the sprite. Default value is 1.




参数 描述
background_element_id The unique ID value of the background element to get the information from




var lay_id = layer_get_id("Background_sky");
var back_id = layer_background_get_id(lay_id);
if layer_background_get_speed(back_id) > 0
   layer_background_speed(back_id, 0);

The above code will get the layer ID for the layer named "Background_sky" and then use that to get the ID of the background element on that layer. This ID is then used to check the animation speed for the element and if it is greater than 0, it is set to 0.
