The
Jump-thru behavior allows the
Platform behavior to stand on the object, and jump on to it from underneath. This differs from the
Solid behavior, which the Platform behavior can stand on, but not jump on to from underneath. The image below illustrates the difference.
The Jump-thru behavior has no properties, conditions, actions or expressions. Because of this, it is also known as an
attribute, since it simply enables the jump-thru ability for the Platform behavior.
