Shadows from sprites

Shadowsprites are an alternative method to cast shadows.

important

shadowsprites are slower than mesh shadows, and don't support depth.

Creating a Shadow sprite

You can create a shadowsprite with 2 functions.

// manually

ss_id = glr_shadowsprite_create(sprite, subimg, px, py, xscale, yscale, rotation, is_static)

// or from the object instance

// in this case it will use the object informations like x, y, scale, etc.

var is_static = false;

ss_id = glr_shadowsprite_create_from_instance(is_static);

You can move/rotate/scale a shadowsprite with

glr_shadowsprite_set_transform(ss_id, x, y, image_xscale, image_yscale, image_angle );

important

Static shadowsprites should not be moved and are way faster since they don't require a refresh for static lights.
