sprite_get_bbox_bottom(ind);
| Argument | Description |
|---|---|
| ind | The index of the sprite to check. |
Returns: Real
This function returns the relative position of the bottom of the
sprite bounding box. This value is given as a relative value based
on the upper left corner of the base sprite asset being (0,0). it
is the same value as can be found in the sprite editor for the
collision mask properties. The image below shows how it is
calculated:
var ww, hh;
ww = sprite_get_bbox_left(sprite_index) -
sprite_get_bbox_right(sprite_index);
hh = sprite_get_bbox_bottom(sprite_index) -
sprite_get_bbox_top(sprite_index);
The above code calculates the width and height of the collision mask based on the relative bounding box side positions.
