描述

This function can be used to retrieve the unique layer ID value for the given particle system. You supply the particle system ID value (as returned by the function part_system_create_layer) and the function will return the ID value of the layer. Note that if the particle system has been flagged as persistent, then it may have been placed on a managed layer (if the layer defined when the system was created in a previous room does not exist), meaning that the value returned will be 0.

语法：

part_system_get_layer(ind);

参数	描述
ind	The particle system ID value to get the layer ID of

返回：

Real (unique layer ID value or 0 if the layer is an internally managed one)

例如：

if part_system_get_layer(global.p_sys) != "effects_layer"
    {
    part_system_layer(global.p_sys, "effects_layer";
    }

The above code will check a particle system to see what layer it is on and if it is not on the given layer it will be changed.
