layer_sprite_get_angle

描述

This function can be used to get the current angle for the sprite element. You give the sprite element ID (which you get when you create a sprite element using layer_sprite_create() or when you use the function layer_sprite_get_id()), and the function will return real value for the angle. This value will be between 0 and 360, where 0 represents right, 90 up, 180 left and 270 down.

语法：

layer_sprite_get_angle(sprite_element_id);

参数：

参数	描述
sprite_element_id	The unique ID value of the sprite element to get the information from

返回：

Real（实数）

例如：

var lay_id = layer_get_id("sprite_sky");
var spr_id = layer_sprite_get_id(lay_id, "Clouds");
if layer_sprite_get_angle(spr_id) != 0
   {
   layer_sprite_yscale(spr_id, 0);
   }

The above code will get the layer ID for the layer named "sprite_sky" and then use that to get the ID of the sprite element on that layer. This ID is then used to check the angle and if it is anything other than 0 it is set to 0.
